Benefits of Using Fertilizer with Organic Fertilizer

Lead: Do you still apply NPK to your own fields today? Now the soil is no longer allowed! In the fertilizing process of crops, some farmers tend to apply chemical fertilizers, which often leads to problems such as soil compaction. However, if organic fertilizers are used in combination with chemical fertilizers, they will have a very good effect.

1, can improve fertilizer efficiency

Fertilizers such as superphosphate are applied to the soil and are immobilized by soil and fail. When used in combination with organic fertilizers, it reduces the contact surface with the soil and reduces the fixing of nutrients. Organic fertilizers can also increase the solubility of phosphate rock and are better under paddy conditions.

After many fertilizers are mixed with organic fertilizers, fertilizers can be absorbed by organic fertilizers to reduce losses. In addition, organic fertilizer with organic fertilizer can also promote the maturity of organic fertilizer, improve fertilizer efficiency.

Experiments have shown that the use of chemical fertilizers in combination with organic fertilizers can both reduce the soil redox potential and reduce ammonia nitration, as well as reduce the loss of nitrogen. Generally can increase nitrogen fertilizer utilization by 10% to 15%.

2, can reduce some of the unfavorable side effects that chemical fertilizers may produce

When a large application of large-scale fertilizer or chemical fertilizer is not applied uniformly, the concentration of soil solution is high, which affects the water absorption of crops and even damages the roots. This problem does not occur if it is mixed with organic fertilizers.

In addition, if the physiological acid fertilizer is applied alone for a long period of time, the soil will become acid, and excessive active iron, active aluminum and other harmful substances will be generated, and the crop will be poisoned. In combination with organic fertilizers, soil buffering performance can be increased and soil acidification can be prevented.

Another example, some superphosphates contain too much free acid, which can affect seed germination and seedling growth when used as a seed fertilizer. Neutralization of free acids after organic fertilizers are added can reduce the harm to the seeds.

3, can increase crop nutrition

Organic manure contains more nutrients and has a stable and long-lasting fertilizer effect. It contains many organic substances and can increase soil organic matter content and improve soil physical and chemical properties. Not only can supply crops, but also can supply soil microorganisms with nitrogen, phosphorus, potassium and other nutrients, as well as vitamins and growth hormone. After the application of organic fertilizer, soil enzyme activity is enhanced, which is conducive to nutrient conversion.

Such as organic fertilizer mixed with superphosphate or superphosphate magnesium fertilizer can promote the growth of aerobic bacteria in the soil, increase crop nitrogen nutrition. According to experiments, the use of chemical fertilizers in combination with organic fertilizers for three years is 0.08%-0.11% higher than that of single-fertilizer soils, ammoniac bacteria is increased by 260%, aerobic bacteria are increased by 119%, and cellulolytic bacteria are increased by 600. %.

4. Adding chemical nitrogen fertilizer when returning straw and applying unfermented organic fertilizer

This can avoid the slow supply of crops due to the early lack of nitrogen and affect the growth, and the maturity phase of cereal crops need to provide both nitrate nitrogen and ammonium nitrogen, organic fertilizer can do this.
