What alternatives can you think of to lessen the need for agricultural chemicals?
What will be an ideal response?
Agricultural chemicals can be made to degrade more rapidly and are thus safer. However, a number of reduced-till and no-till options are being used successfully now. Genetic engineering pest-resistant crops will help reduce our use of pesticides. If agricultural fertilizers are applied right at the time the plants can use them, rather than when seeds are planted, it would reduce runoff of fertilizers. Planting shelterbelts of trees around fields helps reduce runoff and increases habitat and species diversity. Alternating soybeans with corn in the same field reduces the need for application of nitrogen fertilizers, since soybeans are legumes and add nitrogen to the soil.
