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.Know More
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
Fish farming has the advantage of providing a consistent supply of fish for food and providing a source of income and employment. Disadvantages of fish farming include possible water pollution and the need to provide feed for the fish.Full Answer >
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 >
Between the end of the Civil War and the 1930s, Southern cotton farmers used the crop-lien system for credit so that they could survive until the crop came in each year. Tenant farmers and sharecroppers who were not landowners had to get food and supplies on credit from local business owners. When the cotton crop came in, these merchants had a lien on the crop, and they received the first share of the profits, with the leftovers going to the farmer.Full Answer >
The primary disadvantage of shifting cultivation, also called slash and burn or swidden agriculture, is the destruction of large areas of land, primarily crop fields and tracts of forest. When performed improperly, slash and burn can make once-fertile lands unable to support the new growth of crops and plants. Slash and burn may cause environmental and economic consequences by reducing the growth potential for crops in certain areas, which limits the variety and quantity of agricultural goods farmers can produce.Full Answer >
