Final answer:
The question asks for the term related to tilling sideways across a hillside to slow water running down the slope, which is known as contour farming. Other farming methods such as swidden agriculture, green manures, shelterbelts, intercropping, conservation tillage, crop rotation and terracing are also discussed.
Step-by-step explanation:
Tilling sideways across a hillside to slow water running down the slope is known as contour farming. This method helps prevent soil erosion and conserves water. A couple of other terms defined here are: swidden agriculture, which is a farming technique in which vegetation is cut down and then burned to create a field, also known as slash and burn. Green manures are crops that are grown to be turned into the soil to improve its fertility. Shelterbelts are rows of trees that protect crops from damaging winds. Intercropping involves growing two or more types of crops in the same field. Conservation tillage is a farming practice which leaves the previous year’s crop residue on the field before and after planting the next, reducing erosion and runoff. Crop rotation is the process of growing different types of crops in the same area over a sequence of seasons to help replenish soil nutrients. Lastly, terracing is the practice of cutting flat areas out of a hilly or mountainous landscape to grow crops.
