Generally, yes. Since organic farms cannot use many of the insecticides, growth hormones, various chemicals and genetically modified organisms, they must rely on healthier and naturally rich soil. Although the soil is more susceptible to natural bacteria, molds, and pests, it is clean of the slurry of chemicals, hormones, and other unnaturally modified substances that non-organic farms can use.
In most cases, yes. Organic farming requires diverse, intact ecosystems, both above and below ground. Organic farmers rely on biodiversity above ground (predators and parasitoids) to control pests, and biodiversity below ground (the soil food web) to cycle nutrients to their crops.
Organic farmers have to avoid concentrated toxins and persistent chemicals in controlling pests, and rely instead on an enhanced ecosystem with lots of natural enemies. The border areas around organic farms are a critical part of this strategy. Since they’re not using persistent toxins, the soil around the perimeter of organic farms has greater biodiversity than soil around conventional farms.
Organic farmers rely on the soil food web to feed their plants, so they strive to increase soil organic matter by proper crop rotation, green manures, and adding compost and composted manure to soil on a regular basis. These soil management practices have residual effects around the borders of organic farms.
