Everyone knows that different soils contain different nutrients and are suitable for growing crops. Therefore, different soil fertigation methods are also different. Let's introduce them in detail.
Sandy soil: The soil is sandy, loose in soil, and has many coarse grains. The performance of the capillary tube is poor, and the fertilizer and water are easy to lose. The potential nutrient content is low. This type of soil should be applied more organic fertilizer, such as soil miscellaneous fertilizer, straw returned to the field, or a kind of green manure fertilization fertility timely, and gradually improve the soil properties.
Clay: This kind of soil is of heavy texture and has strong fertility and water retention capacity, but its permeability is poor and its fertilizer efficiency is slow. Therefore, the application of organic fertilizer must be fully brewed and decomposed, the topdressing of chemical fertilizers should be appropriate early, and should "eat more meals," appropriate to reduce the frequency of fertilization, the late bogey over-application of nitrogen fertilizer to prevent sluggish crop maturity. In addition, cultivating loose soil and improving soil ventilation should also be carried out.
Loam: A soil with good agronomic traits. Its permeability, conservation, potential nutrient content between sand and clay, suitable for all types of crop growth, generally according to output requirements and crop appearance, timely and appropriate fertilizer. However, it is also necessary to apply rationally, fertilize fertility, and better play the role of increasing fertilizer production. In principle, it is necessary to combine long-acting fertilizer with short-acting fertilizer to meet the fertilizer demand in different growth periods of crops in a timely manner. Organic and chemical fertilizers are combined to fertilize the soil and be used for the same purpose; a large amount of fertilizer and micro-fertilizer combine to provide the plant in time. Need all kinds of nutrients.
Different soil fertilization methods are different. I hope everyone will classify them during fertilization.
Low Residue VOID OPEN Security Labels
