Profile of an agronomist

Agronomists facilitate the connection among producers and crop researchersregarding to new developments in crop varieties, disease and pest control, croprotation, and tillage systems to be implemented into farmers growingoperations.

Job duties

Communicate the community the latest methods for controlling disease,weeds, and insects.

Advise farmers on cropping practices that will improve their incomes aswell as protect environmental sustainability. Evaluate new crop cultivars and their potential in a grower's cropping

program. Encourage the use of best management practices for farming techniques

to minimize soil erosion. Monitor the effects of soil characteristics, water levels, and water

drainage on plant growth and implement crop management practices inorder to enhance production.

Work with producers to analyze crop nutrient needs and fertilityprograms.

Participate in technology transfer and training activities. Evaluate crop performance with management practices.

Workplace

The agronomist can work in an office doing paper work, participating as a policymaker or communicating with colleagues or experts in the field. In the field theagronomist can make presentations to farms and solve problems withproducers.

Agriculture

It is the science or art of cultivating the soil, growing and harvesting crops,

and raising livestock.

Types of FarmingArable farms are ones where the main way of making money is by growing

crops.

Livestock farms are where animals and crops are both important part of the

farm.

Mixed farms are where animals and crops are both important to the farmer.

Branches of agricultureAmong the branches of agriculture we have: Agronomy, horticulture, silviculture,

apiculture, aquaculture, ranching and forestry.

Agronomy: It is the science and technology of producing and using plants for

food, fuel, feed, fiber and reclamation. Agronomy encompasses work in the

areas of plant genetics, plant physiology, meteorology, and soil science.

Horticulture: It is the science , art, and business involved in intensive plant

cultivation for human use.

Silviculture is the practice of controlling the establishment, growth, composition,

health, and quality of forests to meet diverse needs and values.

Apiculture: It is also known as beekeeping is the maintenance of honey bees

colonies, commonly in hives, by humans.

Aquaculture is also known as aquafarming that is the farming of aquatic

organisms such as fish, crustaceans, molluscs, and aquatic plants.

Ranching is a method to raise less common livestock such as elk, American

bison. Ostrich, emu and alpacas.

Forestry: It is the science, art, of conserving forests and associated resources in

a sustainable manner to meet desired goals, needs and values for human

benefit and it is practiced in natural plantations and stands.

ORGANIC & CONVENTIONAL FOOD

ORGANIC FOOD

What is organic food?Food grows without synthetic pesticides or artificial fertilizers. The organicfarming is conducted for crop rotations and spread of manure to keep weeds atbay.Products that are completely organic such as fruits, vegetables, eggs orother single-ingredient foods are labeled 100 percent organic and can carrythe USDA ( The U.S. Department of Agriculture) seal.

INORGANIC FARMING OR CONVENTIONAL AGRICULTURE

It is a production system extremely artificial based on high consumption of

external inputs ( fossil, energy, chemicals, etc) without considering the natural

cycles.

Among the advantages and disadvantages of organic farming we have

Advantages of Organic Food

Reduces pollutants in groundwater and creates richer soil that aids plantgrowth while reducing erosion.

The flavor of organic fruit is better because it is a mixture of manydifferent and complex molecules.

It increases the soil fertility as a biological process and the nutrientsremoved from the crops are replaced.

Protect Future Generations because numerous studies show thatpesticides can adversely affect the nervous system, increase the risk ofcancer, and decrease fertility.

Build healthy soil through elevating the antioxidants levels.

Promotes biodiversity because it respects the animals habitats.

It is required in a number of alternative treatments like cancer therapiesdue to the absence of pesticide residues.

Disadvantages of Organic Food

Traditional fungicides generally kill any toxins creating molds, but organicfarms may be more susceptible to this hazard because such fungicidesare not allowed in organic production.

Manure and compost are often used to fertilize organic food but this canincrease the risk of fecal contamination of the organic food elevating thefecal-carried diseases like E. Coli.

The group of organic farming producers is smaller than the group ofconventional crops producers.

Differences between conventional and organic farming

Conventional OrganicApply chemical fertilizers topromote plant growth.

Apply natural fertilizers, such asmanure or compost, to feed soil andplants.

Spray synthetic insecticides toreduce pests and disease.

Spray pesticides from natural sources;use beneficial insects and birds,mating disruption or traps to reducepests and disease.

Use synthetic herbicides to manageweeds.

Use environmentally-generated plant-killing compounds; rotate crops, till,hand weed to manage weeds.

Give animals antibiotics, growthhormones and medications toprevent disease and spur growth.

Give animals organic feed and allowthem access to the outdoors. Usepreventive measures such asrotational grazing, a balanced diet andclean housing to help minimizedisease.

Nutritional Value

Organic Crops contained more significantly more vitamin C, iron, magnesium,and phosphorus and significantly less nitrates than conventional crops. The

recommended daily intake of organic vegetables is 75 mg for women and 90mg

for men.

Agricultural Machinery

It is any kind of machinery used on a farm to help with farming.

Types of Agricultural Machinery Traction and Power Self Propelled Machinery Soil cultivation Planting Fertilizing and Pest control Harvesting/ Post-harvesting Hay Making Loading

Traction and Power

We have two types in this group: Tractor and Crawler Tractor.

Self Propelled Machinery

We have 8 different types in this category: Bean harvester, beet harvester,

combine harvester, forage harvester, maize harvester, pea harvester, potato

harvester and rape swatter.

Soil Cultivation

We use these machinery for the soil: cultivator, chisel plow, harrow, plough,power tiller, portavator and spading machine.

Planting.

We can use a broadcast seeder, plastic mulch layer, potato planter, seed drill,

air seeder, and transplanter.

Fertilizing and Pest Control

We can fertilizer using these: terragator, manure spreader, sprayer, lime

spreader, slurry injector, and vacuum tanker.

Harvesting/ Post-Harvesting

We can harvest with these: potato digger, beet harvester, drum mower, trailer,

grain trailer, bale trailer, vegetable picker.

Hay Making

We can rack the hay using bale grab, baler, conditioner, hay rake, hay tedder,

hay cart, and mower.

Loading


9/24

8

We can use these devices: backhoe, front loader, rear loader, skid-steer loader.

Agricultural Plagues

A plague is an animal that produces damage to a crop, to people causing

diseases and economic loss in the agricultural work.

Types of Plagues

The Stem Borer

When the plant is young (spring), the newborn Larvitar feed on the leaves

causing small symmetrical holes and damage the terminal bud (bud) killing the

plant in early stages.

Weevil

These can be viewed by cutting up the corn. The damage is caused by the

larva. Sometimes adults can be seen in affected plantations and the presence

of these insects are monitored through a trap.

Nematodes

Nematodes are tiny worms that are only found when using a microscope. The

presence of swelling or reddish-brown lesions is an indicator of the presence of

nematodes.

TYPES OF PLAGUES

Control of Pests

There are three kinds of control: cultural, biological and chemical.

The cultural control is when the agronomist use different techniques to control

the pests. Besides, The biological consists on the use of natural methods such

as the use of natural pests as depredators. Finally, The chemical control iswhen we use the pesticides to kill the insects that affect the crops.

Agricultural Products

The coffee

Since 1860 the coffee is cultivated in Ecuador, especially in Jipijapa, which is

the best area for the coffee .

More than 105.137 families are dedicated to the coffee production. Our country

has more than 5 associatives organizations and 53 exporting organizations.

250 million of dollar in coffee were exported in 2011 ( 55% and 45% in

industrialised grain approximately)

Ecuador is one of the largest exporters of dried coffee.

Ecuador has a great production capacity: It is one of the few countries that

export all the varieties of coffee: washed Arabic, natural Arabic and robust. The

different ecosystems of the country give the opportunity to cultivate the coffee in

each part of Ecuador, even in the Galapagos Islands. The location of our

country makes our coffee one of the best in the world and it is very demanded

in Europe. In our country the production of The Arabic coffee begins in March

and ends in October, but the production of Robust coffee begins in February

and ends in November.

The potential Characteristics and benefits of coffee of the area

The coffee surface is 200.000 Ha.

The socio-organization strength ( more than 5 export partner organizations and

53 base organizations)

Exportation: 258 million in 2011 ( nearly 55% coffee industrialised and 45%

coffee in grain.)

Production and target market

The production of Washed Arabic is majority in El Oro, Manab, Loja. Guayas

and Zamora Chinchipe. Natural Arabic in Loja, Manab. El Oro, Los Ros and

Guayas and Robust in Pichincha, Orellana, Sucumbos and Manab.

In Ecuador the exportation of coffee during the 2011 was nearly 55.512 Tones.

The ecological importance is manifested in the wide adaptability of coffee to

different agro-ecosystems of Coast, Highlands., the Amazon Region and the

Galapagos Islands.

The social importance relates to generate direct employment for 150.000

families of farmers in activities like trade, agribusiness, craft, instant coffee

industry, transport, and export.

The organization of an important segment of the coffee that forms a broad

social fabric and actively participate in national life, becoming a partner

organizational strength.

Benefits of coffee

Scientifically proven that moderate coffee consumption help to prevent diseases

such as : cancer , diabetes and cirrhosis.

Cancer: Research in Europe, USA and Japan found that people who drink more

than four cups of coffee per day is 24% less likely to develop colorectal cancer

as it inhibits the secretion of bilic acids that are the precursors of this disease.

Diabetes: According to the studies of the university of Helsinki ( Finland) coffee

reduces the risk of type 2 diabetes because theophylline and caffeine are

stimulants of pancreatic cell, which produce insulin the body needs.

Cirrhosis: Research with more than 128.000 adults found that people who take

the same amount of coffee, has 5 times less likely to develop liver cirrhosis or

reduce mortality by 30% if the patient is already sick.

The molisoles are soil grassland, with dominance of clays and soil of dark

colour.

The oxisoles are present 1:1 ratio of clay, soils of low fertility and they are red

and yellow colour, due to the high concentration of iron.

The vertisoles are soils rich in clay, with strong expansion and they are gray or

black colour.

Farm Tractor Rollover Prevention

There are nine steps that tractor operators must follow to avoid overturns

1)Safe operation : the operator tractor must read the operator manual . knows

the equipment and how it handles.

2)Fasten Seat Belts Securely: The seat prevents the tractor operator from being

thrown crushed or receive a severe injury if an upset occurs.

3)Avoid steep slopes: Watch out for bumps on the uphill side. Keep side-

mounted equipment on the uphill side.

4)Reduce Speed: When turning, crossing slopes or on rough, slick or muddy

surfaces reduce speed. A raised front-end loader is more likely to cause a

rollover.


14/24

13

OPERATIONS TO AVOID

5)Rules and regulations: A small moving vehicle (SMV) must be visible for a

minimum of 500 ft Attach the SMV emblem to the rear of tower equipment if it

obscures the rear of the tractor.

6)Operate tractor smoothly: Slow down before stopping ot turning when towingequipment. Sudden high-.speed braking can cause the equipment to jackknife

or roll over . Turn safely by reducing engine speed, applying both brakes if

needed and make a wide turn and allow the engines power to pull the load.

7)No riders: Tractors are designed for one operator, no passengers.

8)Hitching: Hitch as low as possible as hitching above the normal drawbar

height may cause the tractor to tip over backward.

9)Parking: If the tractor does not have a parking brake, shift the transmissionlever into the park position. Lower and raised equipment and remove the

ignition key.

Falls from Tractors and Trailing Equipment

Runovers caused by falls from tractors and trailing equipment are one of themost common forms of unintentional injuries that happen on the farm or ranch.Falls from machinery can be prevented by adopting these basic practices:

Wear shoes and boots with slip-resistant soles and heels. Keep platforms, foot-plates and steps clear of mud, snow, manure or otherdebris. Before moving, check the tractor and trailing equipment to see that no one hasclimbed aboard without your knowledge. Remove tools or other items that may cause a tripping hazard from theoperator platform. Don't use working farm equipment as a place to baby-sit children. Arrange forproper childcare. Never allow anyone to ride on the drawbar or towed machinery.

Insist that no one ride on farm equ ipment except those required for itsoperation, instruction, or diagnostics. Reduce speed on rough, uneven or hilly ground. Watch for obstacles. Wait for the tractor to stop before getting off. Set brakes and step down usinghandholds or rails.

Tractor Safety

Farm tractors provide the primary source of power on many farms, but it is also

involved in a high proportion of farm fatalities and severe injuries. To avoid


15/24

14

them, follow safe management principles and implement a tractor safetyprogram on your farm.

Develop a "safety first" attitude. Be physically and mentally fit when operating tractors. Fatigue, stress,

medication, alcohol and drugs can detract from safe tractor operation. Takebreaks. Read operator's manual and warning decals.Equip the tractor with a Rollover Protective Structure (ROPS) and wear seatbelts. Inspect the tractor for any hazards and correct them before operating. Make sure everyone who operates a tractor has received training and isphysically able to operate it safely. Shut down equipment, turn off engine, remove key and wait for moving partsto stop before dismounting equipment. Keep bystanders and others away from tractor operation, especially children.

Livestock Handling Safety

It is important to recognize the symptoms of dangerous animals to avoid injuries or

even the death. Among the symptoms we have to recognize from animals are: raised

or pinned ears, raised tail, raised hair on the back, bare teeth, pawing the ground,

Stiffed-legged gate, snorting and growling.

PESTICIDE POISONING

The pesticides are a diverse group of substances with toxic effects. There are

many forms to be intoxicated: by inhalation, dermal exposure, ingestion and

ocular exposure.

The inhalation through dusts, vapor, mists and gases represent a significant

occupational hazard. The absorption through the skin is determined by the

nature of the pesticide. Condition of the exposed skin, and external factors,

such as temperature, duration of exposure and the area exposed. The ingestionmay occur through accidental splashing of chemicals n the face and mouth,


16/24

15

eating contaminated food, using contaminated smoking materials, or by rubbing

the face with contaminated hands or gloves.

The ocular exposure is usually the result of accidental splashing a pesticide

while no wearing eye protection and may cause effects as burns to the eyelids

and conjunctiva

PESTICIDE FAMILIES AND SYMPTOMS

The Organ Phosphates are cholinesterase inhibitors (nerve poisons) and range

in toxicity from mild to acutely toxic. This family of pesticide includes: carbomate

and chlorinated hydrocarbons.

The carbomate are cholinesterase inhibitors that include carbaryl, dimetilan,

landrin, carbofuran and propoxur. The symptoms may include: headaches.Nervousness, nausea, diarrhea, vision or respiratory difficulties.

The chlorinated hydrocarbons are now banned in the U.S. because they affect

the central nervous system or can depress or stimulate the central nervous

system. This pesticide family includes Aldrin, BHC, Chlordane, DDt, Diedrin,

Heptachlor, Lindane, Mirex and Toxaphene. The symptoms may include:

constricted pupils, fatigue, diarrhea, stomach pain and tightness in the chest.

GENERAL FIRST AID FOR PESTICIDE POISONING

Keep airway clear, provide artificial respiration, use oxygen available tosupport breathing.

Decontaminate the victim as indicated by the material safety data sheet.

If poison was ingested, and the person is not vomiting and is fullyconscious give the person water with 5 percent sodium bicarbonate.

Consult the insecticide label for active ingredients and specific first-aidtreatment.

Grain Storage Structures and Handling Equipment

Storage and handling of large volumes of grain or feed on farms is common inmany areas. Farm workers should make sure they take the proper steps to putsafety first to prevent injuries, illnesses and even death like the followings:

Label grain bins to warn of entrapment hazards. Lock entrances to grain handling areas to keep bystanders and children out. Install ladders inside bins. Do not enter grain bins that are being loaded or unloaded If it is necessary to enter a bin, shut off and lockout power before entering. Usea safety harness and safety line. Have several people available outside the binto lift entrant out in case of an emergency. Wear approved hearing protection when working around noisy equipment,aeration fans, dryers, etc. Be very cautious of grain that may have gone out of condition. Crusted grainmay have cavities beneath the surface that can collapse, leading to entrapment

and suffocation. Keep bystanders and children away from grain bins and grain handlingequipment.


18/24

17

Safe Use of Hand Tools

Tools have always been indispensable helpmates, and a good set of hand toolsis essential for any farm shop, machinery or facility repair, but they alsocontribute to countless injuries when used incompetently.

Use the correct tool for the job. Keep tools in good condition. Handles should be tight and free from defect.

Cutting tools should be kept sharp. Wedges and punches should be free from"mushroom heads". Use and maintain power tools according to their instructions.

Make sure power tools are properly grounded or are double insulated. Nevercut the three-prong plug off or use a two prong adapter. Switch off and unplug power tools before changing blades or servicing andrepairing. Wear clothing with no strings or loose ends to catch on things. Wear appropriate personal protective equipment (PPE), such as glasses,goggles, dust masks, face shields, hearing protection, etc. Keep bystanders at a safe distance. Keep all guards and shields in place. Learn to use a "push stick" with tablesaws. Unplug and put tools away after use.

Consider locking out power tools to prevent others from using them without

permission, especially young children.


19/24

18

Personal Protective Equipment ( PPE)

Personal protective equipment (PPE) can reduce the number and severity offarm work related injuries and illnesses. Personal protective equipment not onlyhelps protect people but also improves productivity and profits.

Protect your head with a hard hat when performing construction work,trimming trees, repairing machinery, and doing other jobs with head injury risks. Use a sun safety hat to prevent skin cancer. Protect your vision with appropriate safety eyewear (safety glasses, goggles,face-shields) when applying pesticides, fertilizers, working in the shop, or inheavy dust conditions. Protect your hearing with acoustic earmuffs or plugs when operating noisyequipment such as grain dryers, feed grinders, older tractors, chain saws, etc. Protect your lungs with the correct respiratory equipment (dust masks,cartridge respirators, gas masks, air pacts) when working in dusty or moldyconditions, spray painting, applying chemicals, working in bins, tanks, silos, andmanure storage places. Protect your hands from everyday abuse with job-matched gloves and barriercreams.

Protect your feet with safety shoes or boots with non-slip soles and heels. Protect your skin with impervious garments when using toxic or irritatingchemicals. In addition, use sunscreen to protect against the sun's harmful rays.

Manure Pit Gas Hazards

A confined-space hazard that often claims multiple lives before anyone realizes

there is a danger is manure gas. Manure pits can be oxygen-deficient, toxic andexplosive. There are four gases in manure pits that are of primary concern.Hydrogen Sulfide is a highly toxic gas that is heavier than air. It can causedizziness, unconsciousness and death. At low concentrations it may smell likerotten eggs, but at higher concentrations it deadens the sense of smell so thatno odor can be detected.Carbon dioxide is an odorless, tasteless gas that is heavier than air. Itdisplaces the oxygen supply in the bloodstream, which can causeunconsciousness and death.Ammonia is a gas that is lighter than air. It has a pungent smell and can irritatethe eyes and respiratory tract. Ammonia also displaces oxygen in the

bloodstream.Methane is also a gas that is lighter than air. The primary hazard of methanegas is that it can create an explosive atmosphere. This gas also displacesoxygen.It is important to never enter a manure pit alone, label the manure pit and

manure storage areas to warn of the gas hazards, obtain and use monitoring

equipment to determine the level of gases present in the manure storage area

and a safety harness should also be worn and personnel should be available

outside the storage area to monitor the entrant's progress.

Crop Protection Chemical Safety

Crop protection chemicals are necessary to ensure the production of food fromour nation's farms and ranches. They prevent unwanted weeds, insects,rodents, fungus and diseases. When we work with chemical is necessary to dothese things:

Always read packaging labels.

Keep up with Material Safety Data Sheets (MSDS) for the crop protectionchemicals that you use because it contains additional health hazard data, spillor leak procedures and handling information.

Be sure to keep a set separate from the storage area and label it when it

contains pesticides.

Wearpersonal protective equipment (PPE) such as: chemical-resistant gloves,coveralls, boots, hat and apron, approved respirator with cartridges forpesticides, and chemical protection goggles and face shield to prevent workaccidents.

Keep crop protection chemicals in storage areas that can be locked to ke ep

bystanders and children . Launder chemical-soiled c

lothing separately from other laundry and triple rinse
