Corn Belt soybeans, no leakage in nine out of ten years, what does this sentence mean?

The meaning of the saying "Soybeans in the Corn Belt will not be lost nine times out of ten years" means that the benefit of interplanting soybeans in corn fields is that it saves land and can harvest more food. Farmers cherish their land very much. In order not to waste every bit of land, they often use intercropping when planting crops. That is to plant two crops in one field, which does not affect each other and maximizes the benefits of land and soil. . Of course, there are some issues that need to be paid attention to when interplanting. For example, it is best to choose crops that are high and short. In addition, when preparing to interplant crops, the distance should be as wide as possible so as not to affect ventilation.

Everyone knows that planting sweet potatoes requires ridges, so that there will be a free space at the bottom between the ridges. Farmers are reluctant to leave the open space between the ridges for sweet potatoes, so they will plant them in the open space at the bottom. Plant crops such as sesame or soybeans, and some people also plant corn. In short, these crops basically grow stalks, and sweet potatoes are vine crops and will not affect the growth of each other. It should be noted that for interplanted crops such as soybeans and sesame, the distance between plants should be larger and should not be planted too densely. The same goes for interplanting soybeans in corn fields.

Farmers grow corn in two seasons, one is spring corn and the other is summer corn. When planting spring corn, the distance is usually about 40 centimeters, so of course there is no way to interplant soybeans. As long as corn is planted after the wheat harvest, soybeans will be interplanted with corn. The time to plant summer corn is usually after farmers harvest the wheat and then plant corn directly in the wheat field. This planting method is to plant corn on the back of the ridges on both sides of the wheat field, and the distance between the wheat ridges is at least Four feet, which is one meter and three meters of open space. Of course, such a large place cannot be left idle, so farmers usually choose to interplant soybeans in corn fields.

The purpose of interplanting soybeans is not only to save land and harvest more food. There is another benefit, that is, if the land is left idle, the weeds in the field will grow wildly after a rain. This not only wastes the land, but the weeds can also absorb the nutrients of crops and affect the harvest of crops, so regardless of From whatever aspect you think about, you should interplant another crop. This will not only increase production and income, but also prevent grass from growing in the field. Once the field is full of weeds, it is easier to get rid of the weeds than to manage crops.
