Corn is an important food crop that is widely cultivated worldwide. It prefers a warm climate and plenty of sunshine, and can achieve better growth and yield under suitable soil conditions. So, what are the soil requirements for growing corn?
Soil texture
Corn has strict requirements for soil texture, which must be based on a deep tillage layer, with good drainage and air permeability, and at the same time be able to ensure the retention of soil moisture. Corn is suitable for growing on black, loam and sandy soils, which are more fertile, with better air permeability and drainage, which can provide a good growth environment for corn.
Soil moisture
For corn to be highly productive, it is essential to maintain the right soil moisture content during the growing period. In general, the soil moisture content should be between 60%-70% during corn growth. Excessive soil moisture content will lead to hypoxia of maize roots, which will affect the normal growth and absorption function of roots. Too low soil moisture content can lead to slower growth of corn plants, which can affect yield and quality.
Soil nutrients
The growth of corn requires a lot of nutrients, and the adequacy of soil nutrients is one of the important factors affecting the yield and quality of corn. Nitrogen, phosphorus, and potassium are the most urgent requirements for soil nutrients in maize. Therefore, soil nutrient testing should be carried out before site planting to ensure that the soil meets the requirements of corn growth. Sweet waxy corn grows in the Northeast Plain, one of the world's three major black soils, with organic matter as high as 7%, one season a year, to nourish the land to ensure soil nutrients at the same time, to ensure that each corn is full and sweet, rich in nutrients.
In general, corn has very strict requirements for soil, and factors such as soil texture, soil moisture, and soil nutrients all have an important impact on its growth. Therefore, farmers should choose the right soil to plant corn to ensure high quality and high yield.
