A monoculture is when a large amount of one crop planted in a field. This has detrimental effects on the soil because this crop takes in the nutrient out of the soil, leaving it deficient and unable to sustain other crops. The monocultures also attract many pests. Since there are no other plants that would attract other pests, which in turn would make these pests compete and therefore regulate the amount of insects, farmers uses a large amount of pesticides and insecticides.
