What impacts the growth of healthy crops and how do farmers and scientists help to make it better?
Many factors impact the growth of healthy crops. Weeds, plant diseases, and insects can be harmful to crops, threatening their healthy growth and development. Many farmers and scientists work together to combat this problem. Today, many farmers control pests by using chemicals called pesticides and herbicides. Although these chemicals are useful, they can pollute our environment if they are not used properly. They can also cause health problems for people and animals. **These activities are the result of questions and discoveries raised by the students. One way that some farmers and scientists are attempting to combat this problem is through organic farming. Natural substances rather than chemicals are used to fertilize soil and control pests. Many farmers conduct organic farming by rotating their crops each year. Crop rotation helps fight against disease and insect pests in a special way. Usually, if certain crops are planted and grow in the same field each year, diseases and insects
