What are the benefits of interplanting corn with soybeans? How to plant large land households?

Corn plants are the same height, and after intercropping, it can be better ventilated and transparent, avoiding canopy, which is beneficial to the growth of corn. Moreover, soybean is a short-day crop, and corn can just block some sunlight without affecting ventilation and soybean growth. Corn has a well-developed root system, which can penetrate deep into the soil and absorb more nutrients and water. The root system of soybean is shallow, that is, it is afraid of drought and waterlogging. Intercropping can improve the drought tolerance of soybean. In other words, even in a dry and rainy year, you can ensure that soybeans will be harvested and will not be abandoned. Planting method: expand the spacing of corn belts, preferably 2.4-2.7 meters. This will help soybeans get more light. In addition, it is suggested that the number of rows for soybean sowing should be 4-6, and the plant spacing should be 8- 10 cm.
