What makes food organic? You may be surprised to learn that the answer isn’t as simple as you might think. In fact, there are a number of different factors that contribute to whether or not a food can be considered organic.

Soil health and food
The USDA defines organic as “foods produced without using most conventional pesticides; fertilizers made with synthetic ingredients or sewage sludge; bioengineering; or ionizing radiation.” In other words, organic food is grown in a way that attempts to cycle resources, promote ecological balance, and conserve biodiversity. Simply put: organic food is grown with natural methods.
Organic foods are not necessarily pesticide-free or chemical-free. Certain approved pesticides and herbicides may be used on certified organic farms. For example, Farmers may use biological pest control – such as introducing predators to control pests – and approved Bacillus thuringiensis (Bt) products to manage insects.
Crop rotation, cover crops, green manures, and animal manure all contribute to soil health – which in turn leads to healthier plants that are more resilient to pests and disease. Soil health is essential for organic farming because it helps reduce the need for synthetic inputs.
Pest and disease control in organic farming
Organic farmers use a variety of management practices to control pests and diseases. These include mechanical controls (such as barriers, traps and physical removal), cultural controls (such as crop rotation and choosing resistant varieties), biological controls (such as using beneficial predators, parasites and pathogens), and organic sprays and dusts (such as soaps, oils, sulphur, rotenone, pyrethrum and Biological Control Agents – BCAs).
One of the biggest challenges facing organic farmers is the lack of approved pest control products. In general, there are far fewer products available to organic farmers than to conventional farmers. This means that organic farmers have to be more creative in their approach to pest management, often using a combination of different techniques.
Despite the challenges, organic farming can be very successful. A key reason for this is that organic farms tend to have more diverse crop rotations, which helps to reduce the build-up of pests and diseases. Organic farms also tend to have more beneficial insects, such as ladybirds and lacewings, which help to control pests.
Crop rotation in organic farming
Organic foods are those that are produced without the use of synthetic (man-made) pesticides, herbicides, or fertilizers. In addition, GMOs (genetically modified organisms), hormones, and ionizing radiation cannot be used during the production of organic foods.
Crop rotation is a common practice employed in organic farming. Crop rotation is the practice of growing a series of different types of crops in the same area in sequential seasons for various benefits, including weed and pest control.
Fertilizers and amendments in organic farming
In organic farming, farmers use a variety of methods to maintain and improve their soil quality. They use crop rotation, green manure crops, compost, and mechanical cultivation to keep the soil healthy and minimize the need for synthetic inputs.
The foundation of organic matter in the soil comes from plant and animal residues that are added back to the land. Farmers carefully manage these materials to compost them fully so that they can be used as fertilizer and soil amendments.
The use of synthetic fertilizers and other inputs is prohibited in organic farming. This means that farmers must find ways to build up the fertility of their soil without using these products. The key is to maintain a healthy balance of organic matter in the soil so that it can provide the nutrients plants need to grow well.
Water conservation in organic farming
Water conservation is one of the main reasons to choose organic foods. Farming without chemicals allows topsoil to retain more water, reduces water contamination, and helps keep aquifers from being depleted.
Organic farmers use a variety of techniques to reduce water usage such as terracing, contour planting, crop rotation, and using drought-resistant plants. They also often times create irrigation systems that use less water overall.
Energy conservation in organic farming
Organic farmers use a number of management practices that conserve energy. One example is reduced tillage. Conventional tillage (plowing, disking, and other soil disturbance) prior to planting can run from 4.5 to 9 gallons of diesel fuel per acre. Organic farmers often rely on rotations with cover crops, mulches, and green manures to keep weeds under control, which reduces the need for tillage. One study found that when organic farmers use conservation tillage practices, they can reduce their energy use by 30%.
In addition to improved soil management, organic farmers employ a number of other techniques that can help reduce their overall energy use. For example, they may use windbreaks and hedgerows to protect crops from wind damage and reduce the need for chemical pesticides. They may also plant crops closer together to reduce the amount of land that needs to be cultivated. These and other practices can help organic farmers conserve energy while still producing high-quality food.
Weed management in organic farming
There are three primary weed management strategies in organic farming: prevention, mechanical control, and cultural control. Prevention, also known as crop rotation, is the practice of planting a different crop in a field each year. This strategy reduces the chances of weeds infesting a field by depriving them of their preferred host plant. Mechanical control, also known as tillage, involves using machines to remove weeds from fields. This strategy is often used in conjunction with crop rotation to further reduce the chances of weeds infesting a field. Cultural control involves manipulating the environment to make it less conducive to weed growth. This might involve choosing crop varieties that are less susceptible to weed infestation or making changes to irrigation and fertilization practices.
Soil erosion and degradation in organic farming
Organic farming practices are designed to promote soil health, minimize soil erosion and degradation, and increase soil carbon levels. One way to build and maintain healthy soils is by using cover crops. Cover crops are plants grown for the purpose of protecting and improving the soil rather than for harvest. They improve soil health by providing living roots that help hold soil in place and improve its structure; increase biodiversity; and help regulate water, nutrient, and pest cycles.
Sustainability of organic farming
Organic foods are those that are produced without the use of synthetic (man-made) chemicals. To be certified “organic,” a farmer must follow specific standards that are designed to promote the sustainability of both the land and the food it produces.
The standards for organic farming were developed in the 1940s by a group of farmers in India who were trying to find a way to farm without using synthetic chemicals. These standards were later codified into law in many countries, including the United States.
In order to be certified organic, a farmer must demonstrate that they are using sustainable practices that protect the environment and the food they are growing. For example, an organic farmer may use cover crops and crop rotation to improve soil health, or they may use natural methods of pest control instead of synthetic pesticides.
Organic foods have become increasingly popular in recent years as consumers have become more concerned about the impact of synthetic chemicals on their health and the environment. Organic foods are often seen as being more “natural” and “healthier” than non-organic foods, although there is debate about whether these claims are truly accurate.
Whether or not you choose to eat organic foods is a personal decision, but it is important to remember that organic farming is an important step in achieving sustainable food production.
Economic viability of organic farming
In general, organic foods are grown without the use of synthetic pesticides, herbicides, or fertilizers. They also must be produced without genetic engineering, ionizing radiation, or sewage sludge. Furthermore, animals that produce organic meat, poultry, eggs, and dairy products cannot be given growth hormones or antibiotics. For a food to be certified as organic, a farmer must go through a lengthy process with the United States Department of Agriculture (USDA).
The economic viability of organic farming has been a controversial topic. Advocates of organic farming claim that it is more environmentally sustainable than conventional farming practices. They also point to health benefits associated with eating organic foods. Critics of organic farming argue that it is not economically viable on a large scale and that it can actually have negative environmental impacts.
