Generally, the soil with heavy texture has a close structure and poor ventilation(cheap plastic plant pots bulk). In spring, the ground moisture rises slowly, but the ability of water and fertilizer conservation is strong. In spring, the sandy soil with loose texture has a good ventilation and a fast rise of ground temperature, which is conducive to the growth of seedlings, but the ability of water and fertilizer conservation is poor(72 cell seed starter trays). Corn is very sensitive to the air content in the soil.

On the contrary, during the growth period of corn, because of the frequent cultivation and loosening of soil(105 cell plastic propagation tray wholesale price), fertilization and watering, not only can promote the soil weathering, maintain the soil moisture and nutrients, but also can timely prepare the land and keep picking after harvest, with thorns to improve the sowing quality of the following winter wheat, achieve the whole seedling, and obtain high yield(18 cell seed starting trays). The oxygen needed by roots for respiration is mainly supplied by the air of purple soil.(cheapest half gallon nursery pots suppliers canada)
The nitrogen supply of maize is not enough(gallon pot), which can promote the synthesis of various organic substances, strengthen the metabolism process, make the growth of corn stem and leaf flourish, form more chlorophyll, enhance photosynthesis and accumulate more dry matter. Like cotton, it is a kind of aerobic crop that requires good soil ventilation and large air capacity(20 cell seed starting trays). Generally, the most suitable soil oxygen content for corn growth is 10-15%.
(cheapest half gallon nursery pots suppliers canada)Not only the rhizobia of legumes can fix the nitrogen in the air, but also the green manure of legumes can promote the formation of soil aggregate structure(seed starting trays). In the first 30 cm soil layer, the number of grains larger than 0.25 cm is about double that of annual crops(40 cell seed starting trays). Suitable soil water and air conditions can promote the activities of soil aerobic microorganisms, decompose organic matter into effective nutrients, and meet the needs of corn growth.
In the soil with poor ventilation, even if the nitrogen is sufficient, it will often show the symptoms of nitrogen deficiency(square grow pots), increase the anaerobic respiration of the root system, consume a lot of organic matter, and affect the growth of corn. In the southern hilly corn region, where rice is the main crop, the rotation of corn and soybean is due to the long-term water immersion of paddy field(105 cell seed starter trays). Under the condition of poor soil aeration, the ability of corn to absorb various nutrients decreased.
Under the condition of gas aversion, the nutrients in the soil are in the reducing state, the content of nitrate nitrogen is low, and the soil is hardened(plastic plant pots wholesale suppliers). The early rotation of rice and corn with water can improve the soil structure, promote the decomposition of organic matter, change the reducing nutrients into the effective state, and improve the soil fertility(50 cell plastic propagation tray wholesale price). Soil is one of the main media for the spread of crop diseases and insect pests.
According to the margin test of the people in the northern rice and corn production areas(plastic plant trays wholesale), in the case of a thousand droughts and insufficient water sources, the rice fields with good drainage will be changed into corn or soybean, and then planted with wheat for 2-5 years. The implementation of early water rotation can make economic use of water, adjust soil nutrients(104 cell seed starting trays), improve soil structure, and further improve rice and corn production.(cheapest half gallon nursery pots suppliers canada)
