Final answer:
The practice of planting a single crop over a large area, such as soybeans in this case, is called monoculture. Crop rotation, such as alternating corn and soybeans, helps improve soil health and control pests. Natural conditions like drought can greatly impact the supply of agricultural goods.
Step-by-step explanation:
The farmer adjacent to your land who plants a single crop (soybean) over their entire 100 hectare field is practicing what is known as monoculture. This agricultural practice of planting only one type of crop across a large area can have various economic advantages; however, crop rotation, which involves alternating crops like corn and soybeans in successive planting seasons, offers benefits in terms of soil health and pest control.
For instance, growing a legume such as soybeans helps to fix nitrogen in the soil, benefiting subsequent cereal crops like corn which require more nitrogen for growth. Countries like Paraguay, a major producer of soybeans, rely heavily on agriculture, emphasizing the importance of sustainable farming practices to ensure long-term productivity and economic stability.
Natural conditions like drought can severely affect the supply of agricultural goods as seen in the 2014 drought in the Manchurian Plain, where supply of wheat, corn, and soybeans decreased. Conversely, favorable weather conditions can increase the overall agricultural supply, indicating the supply's sensitivity to environmental factors.
