Sand
The soil is sandy, loose, coarse-grained, easy to lose fertilizer and water, and its potential nutrient content is low. This kind of soil should be more organic fertilizer, such as soil miscellaneous fertilizer, straw returning to the field, or planting green manure in a timely manner to turn over and fertilize the soil, and gradually improve soil properties.
clay
This kind of soil has strong fertilizer and water retention capacity, but the permeability is poor and the fertilizer efficiency is slow. The application of organic fertilizer must be fully decomposed, the application of chemical fertilizer should be appropriate early, and it is advisable to "eat more and eat less meals", appropriately reduce the number of fertilization, and avoid applying more nitrogen fertilizer in the later stage to prevent crops from being greedy for green and late ripening.
loam
Loam soils are soils with good agronomic traits. Its permeability, storage and potential nutrient content are between sandy soil and clay, which is suitable for the growth of various crops, and can generally be fertilized in a timely and appropriate amount according to the yield requirements and crop appearance.
Saline-alkali soil
The fertilization principle of saline-alkali soil is mainly based on the application of organic fertilizer and organic activated nutrient fertilizer, and the use of chemical fertilizer is strictly controlled. Organic activated nutrient fertilizer contains a large amount of organic matter, which can buffer harmful anions and cations in the soil, which is conducive to rooting and seedling preservation.
paddy fields and drylands
When selecting organic fertilizer in paddy fields, attention should be paid to the selection of fully decomposed organic fertilizer, otherwise too much reducing matter will be produced. At the same time, due to the vigorous activity of aerophobic bacteria, it will also increase the consumption of oxygen in water, further aggravate soil hypoxia, and cause damage to crop roots.
Dry land is the opposite of paddy field, dry land fertilization not only does not cause nutrient leaching, but also allows nutrients to accumulate gradually in the soil, which can easily cause high salt concentration, so dry land should not be fertilized close to the roots of plants.
