Farmer Answers Farming Questions | Tech Support | WIRED

Farming is an expensive business. For many, a major expense is repair and maintenance of equipment, which can cost hundreds of thousands annually. For those with newer equipment, the cost of purchasing tractors (up to $450,000), combines (approaching $1 million), and cotton pickers (up to $1.2 million) can be the largest expense.

Farmers haul their crops to market, sometimes traveling significant distances to find the best prices. The hardest part of farming is the inherent gamble on weather and market conditions, coupled with the stress of transporting increasingly large equipment on busy public roads.

Farmers do much more than just grow food and fiber; they are also agronomists, pathologists, mechanics, and electricians, requiring diverse knowledge. Their lives are dictated by seasons and weather, often involving long working hours, especially during planting and harvest.

Winter is a crucial preparation period for farmers, involving equipment maintenance, financial planning, seed selection, securing financing, and ongoing training. Farmers are often environmentalists by necessity. To make farming more sustainable, economical, and environmentally friendly, increased funding for independent research at land-grant universities is vital to explore methods for reducing product usage.

Switching to 100% organic farming is possible but challenging. It requires a complete change in agricultural practices, with a three-year transition period where products cannot be sold as organic, leading to lower yields and income. Organic methods restrict the use of many yield-boosting and pest/weed control products, and limit fertilizer options primarily to manure, which is slower-acting.

Farmers use GPS-powered auto-steer systems in modern tractors to achieve perfectly straight rows. An 'AB line' is set by marking a starting and ending point in the field, and the computer then steers the tractor precisely along this line, repeating it across the field.

Must-have tools include tractors for pulling various implements (planters, plows, sprayers), harvest machines like combines for grain crops, specialized harvesters for other crops, grain bins for storage to take advantage of market prices, and equipment sheds to protect expensive machinery from the elements.

Farmers use on-board computer systems in tractors and harvesters to log activities and data. This data, including fertilizer application maps, yield maps, and soil type analysis, is stored and analyzed using software to inform decisions for future growing seasons and manage costs, sales, and inventory effectively.

A bushel is a unit of volume for dry goods (e.g., 56 lbs of corn, 60 lbs of soybeans). Tractor GPS systems are highly accurate, reaching within one inch using RTK (Real-Time Kinematics) technology with base stations. This precision allows for efficient resource use, such as shutting off individual rows to prevent over-application of seeds.

Farming is a dangerous profession due to heavy machinery, chemicals, extreme weather, and financial stress. Becoming a farmer, especially in row cropping, typically requires access to significant land. Many farmers are born into the profession, continuing family legacies.

Farming can have varying profitability. Examples show gross incomes in the millions but net profits can be small or even negative, especially in challenging years due to factors like drought and fluctuating commodity prices versus rising input costs. Subsidies are necessary to support farmers, ensuring a continuous and affordable food supply for society. Programs like subsidized crop insurance help farmers manage risk.

The majority of corn grown in fields (field corn or dent corn) is not for direct human consumption off the cob. It's used for ethanol in gasoline, tortillas, cornbread, and high-fructose corn syrup, a sweetener found in many processed foods and soft drinks.

Soil erosion, caused by water and wind, is a significant problem, as exemplified by the 1930s Dust Bowl. Modern farming uses technology like no-till farming (planting without plowing) and cover cropping (planting non-cash crops to protect soil during fall and winter) to minimize erosion and maintain soil health.

Farmers use pesticides but also employ 'cultural practices' such as crop rotation to break disease cycles. Managing pests like deer often involves allowing hunting, but farmers widely accept a certain level of crop damage.

Plants extract nutrients from the soil, but these are replenished through fertilizers. The amount removed is minimal compared to the overall soil mass, so the soil level doesn't visibly recede. Irrigation methods vary by climate, from center pivots and flood irrigation in wetter areas to efficient drip tape in arid regions, though many farmers rely solely on rainfall.

Trade wars significantly impact American farmers as agricultural commodities are a major U.S. export, particularly to countries like China. Retaliatory tariffs and broken agreements can lead to depressed commodity prices and long-term financial pain for farmers, as exports play a crucial role in the market for corn, soybeans, and cotton.

Crops are bred for maximum yield over longer growing periods, while weeds are naturally selected to grow quickly and produce seeds for survival. GMOs (Genetically Modified Organisms), like corn with a BT gene for pest resistance or herbicide tolerance, are considered perfectly safe for consumption by farmers.
