The primary advantages of crop rotation include preserving fertile soil, enhancing the health of crops and minimizing the amount of pests, while the primary drawbacks and challenges include lingering fungi and pests. Another major drawback is the time involved in preparing the soil for new crops.Continue Reading
Certain insects and pests feed on different types of crops. By rotating crops, a person removes the food resource preferred by one pest. Therefore, that particular pest eventually dies. It is also less likely that pest populations build up. A reduction in the pest population improves the quality of the soil and mitigates the amount of crops that are destroyed each season. Rich soil and healthy plants also contribute to fewer weeds. Fewer weeds and stronger plants minimize the amount of chemicals needed to grow crops.
Rotating crops often requires more time in preparing fields for crops ahead of rotations. This point is especially true when rotating every two years instead of every three to four years. Also, the fungi and pests left behind from a previous crop can potentially harm the new crop. Some crops coexist better with weeds and fungi, and a new crop may have a more difficult time. Plant debris can also cause diseases when the new crop is planted.Learn more about Agriculture
Crop rotation is important to cotton farmers because it promotes nutritionally balanced soil and larger harvests. Cotton places great demands on soil because it depletes many of its nutrients, especially nitrogen. This quickly renders the land unsuitable for many other crops. Regularly switching crop locations reduces the negative impact cotton has on arable ground and promotes large harvests of valuable cotton.Full Answer >
Advantages of technology in agriculture include expediting crop production rate and crop quantity, which in turn reduces costs of production for farmers and food costs for consumers, and even makes crops more nutritious and livestock bigger and meatier. Technology in agriculture produces benefits for small-scale farms and national farming operations alike. These technologies include using environmentally sound and sustainable farming methods, such as no-till agriculture, and sophisticated equipment, including biotechnology.Full Answer >
Two major advantages to the use of GMOs, or genetically modified organisms, are increased crop yields and resistance to pests and diseases. Genetic modification does not always involve the use of chemicals and can sometimes be accomplished through grafting, selective breeding and cross-breeding.Full Answer >
Agriculture jobs include managerial roles with a farm or orchard, physical labor jobs harvesting and processing agricultural products, public relations careers representing farms, or scientific jobs studying different aspects of a crop or the farming process. Other jobs include educational roles teaching about the process or history of agriculture or positions as a liaison between farmers and food companies.Full Answer >
