Description

When using compost, the time, amount and method of application are all important, so how to use compost properly?Please see the following for detailed explanation:

1. Application method

Organic fertilizers mainly improve soil and provide nutrients. Combined with deep ploughing, organic fertilizers should be applied into the soil before planting crops, so that organic fertilizers and soil can be completely mixed together, so as to achieve the purpose of improving soil.

The topdressing fertilizer should mainly be fully soluble quick-effect fertilizer, which can be quickly absorbed by the crops after decomposition and has little impact on the soil.

In the base fertilizer, because the nutrients in organic fertilizer are mainly phosphorus, potassium and nitrogen, organic fertilizer should be applied with chemical fertilizer.Phosphorus and potash fertilizer can be applied as base fertilizer once. Phosphorus fertilizer should be applied as base fertilizer to the soil because of poor mobility and poor effect of later topdressing.

2, The time of application

Organic fertilizer has a slow effect and should be applied in advance. Generally, it should be applied one-time base fertilizer before sowing or transplanting. It is best to choose fully fermented and decomposable organic fertilizer before use.

Fertilizer has a quick effect. Base fertilizer should be applied about one week in advance. Top dressing should be applied before the critical period of crop nutrition or the peak of nutrient absorption in order to meet its needs.

Biological fertilizer can only play the role of bacteriostasis after a large number of propagation in the soil, so it should be applied early in the premise of planting, so that it has time to multiply and grow. It can be applied to the soil together with organic fertilizer, or it can be applied in holes before or during planting.

3. Application amount

Different crops have different growth periods and require different amounts of fertilizer.They should be fertilized according to the proportion of fertilizer they need, no more, no less, and take into account the nutrients in the soil.It is best to carry out a soil test, according to the soil test formula for fertilization, to do a good job of overall consideration.
