A combine harvester cuts down a crop, separates the seed from the plant material and stores the clean grain in a tank for transport or offload to another storage device. The combine is a self-propelled machine that is used by farmers to speed up the process of harvesting.Know More
A combine harvester is used to remove mature crops from a field when they are ready to be harvested. The combine has an attachment on the front, called a header, that is determined by the type of crop being harvested. The header is the portion of the combine that actually cuts the plant. The header then moves the plant up the throat and into the combine itself.
Once the plant has been moved out of the header throat, it is pushed into a threshing cylinder, which is used to separate the grain from the plant. The grain and plant material are passed through the combine over sieve beds. The sieves allow the grain to fall through while moving plant material toward the back of the combine. The clean grain that falls through the sieves is moved by clean grain elevators, augers or air delivery into the grain tank. The plant material is ejected out the back of the combine.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 >
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.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 >
Agricultural silos work by creating a pressurized area within a cylindrical container that helps to keep fodder and hay that is used to feed farm animals free from spoilage. There are several different types of silos that vary slightly in design but operate in the same manner to keep animal food from rotting. Most silos exist as upright cylinders that are constructed with sturdy materials such as porcelain or steel that help to prevent corrosion.Full Answer >
