The ideal fertilization method is to apply organic fertilizer first, then apply nitrogen, phosphorus, and potassium fertilizers in a reasonable way and apply them scientifically.
Avoid doing rootless fertilization at noon
The high temperature at noon makes the liquid fertilizer not only evaporate quickly after being sprayed, but also cannot be well preserved in the body surface of the crop, and it is difficult to be absorbed by the stomata and lenticels soon.
Avoid nitrogen fertilizer on topsoil
Apply nitrogenous fertilizer to the shallow layer of the topsoil, and nitrogen is easily decomposed and evaporate when exposed to sunlight.
Avoid excessive application of high-concentration fertilizer
Regardless of the type of fertilizer, if the amount is too large, the root system of the crop will “suck down†and cause damage to the roots.
Avoid spraying with water
Phosphate fertilizer and potash fertilizer are easily fixed, and nitrogen fertilizer is easy to evaporate and lose. Fertilizers applied with water basically stay in the topsoil, and the fertilizer utilization rate is very low.
Avoid ammonia and ammonium bicarbonate in greenhouses or greenhouses
Because the ecological environment within the greenhouse is closed at high temperatures, the two fertilizers are easily volatilized under high temperature and confined conditions, causing the plants to be smoked and affecting normal growth.
Avoid "Lalang match"
Irrespective of the nature of the fertilizer, it is unscientific to mix and apply it arbitrarily. If ammonium fertilizer is applied in combination with alkaline fertilizers such as grass ash, lime, and phosphate fertilizers, it will inevitably accelerate the volatilization of nitrogen, cause waste of fertilizer, and also cause damage to crops.
Avoid application of phosphorus fertilizer
Phosphorus is very mobile in soil, and it is particularly easy to apply it to the surface of the soil for adsorption and fixation, which greatly reduces the fertilizer efficiency of phosphorus.
Avoid applying excessive nitrogen fertilizer to legume crops
The roots of leguminous crops are affiliated with Rhizobium. If nitrogen is used excessively, it will directly affect the ability of Rhizobium to fix nitrogen.
Avoid excessive application of chlorinated fertilizer to sensitive crops
Tobacco, citrus, potato, and grapes are sensitive to fertilizers. Do not apply too much chlorine at a time, otherwise it will affect normal plant growth.
Avoid applying fertilizer before heavy rain
If heavy rain or showers are encountered after fertilization, the fertilizer is easily washed off by the rain, causing loss of nutrients.
Bogey on fertilizers
The application of zinc fertilizer, molybdenum, boron and other fertilizers can solve the problem of crop nutrient deficiency, but if single application of micronutrient fertilizer will cause crop malnutrition, growth and development are hindered.
