Generally, untreated soybean cake fertilizer can not be directly sprinkled into the soil as fertilizer, because it will ferment in the soil and release a lot of heat, thus burning the roots of crops. So small pieces of bean cakes can be mixed with warm water and piled up, then covered with plastic film, and can be used after fermentation. It should be noted that fertilization should not be carried out in rainy days or high temperature periods, but in cloudy days or evening.

1. Can bean cakes be directly sprinkled in the soil as fertilizer?

1. Can bean cakes be directly sprinkled into the soil?

(1) Under normal circumstances, untreated soybean cake fertilizer cannot be directly sprinkled into the soil as fertilizer, because soybean cake will generate a lot of heat after fermentation in the soil, which will burn the roots of crops and further affect the growth of crops, so it needs to be fermented and decomposed before it can be used as fertilizer.

(2) Usually you can cut the bean cake into small pieces, then mix it with warm water and pile it up, then cover it with plastic film and wait for fermentation.

2. Application considerations

(1) Weed and loosen the soil before fertilization.

(1) During the growth of trees, weeds generally grow and compete with them for nutrients, and the soil is easy to harden. If fertilization is applied at this time, the nutrients in the fertilizer are generally difficult to be absorbed by trees.

(2) Therefore, before fertilization, it is necessary to weed and loosen the soil reasonably, so that fertilizer water can penetrate into the soil, so that microorganisms can multiply as soon as possible, accelerate the decomposition speed of organic fertilizer in the soil, provide nutrients for crops and promote their better growth.

(2) Fertilization is not suitable in rainy days.

① Fertilization is not recommended in rainy days, nor in high temperature periods in summer.

② Fertilization can be carried out on cloudy days and in the evening, which is beneficial to the development of fertilizer efficiency.

(3) water after fertilization

Trees need watering after fertilization. More fertilizer and less water are easy to cause fertilizer damage.

Second, how to ferment bean cakes

1, accumulation

(1) First, crush the bean cake and stir it according to the ratio of adding 20kg warm water to each 100kg bean cake.

(2) Then, the bean cakes are piled into a pile with a height of 50-70cm, and sealed and fermented with a plastic film.

(3) Turn it every 4-5 days 1 time. After 2-3 months, if the bean cake turns red in color, has mellow fermentation sweetness, and has a slight caking phenomenon, it represents the completion of fermentation.

Step 2 use containers

(1) Prepare 1 small sealable fermentation containers, such as mineral water bottles, and grind the bean cakes into small particles.

(2) Then put the bean cake and water in a mineral water bottle according to the ratio of 1: 10, seal it, and then ferment it in a dark place with high temperature.

(3) Fermentation can be completed in about 65,438+00 days in summer and 30 days in winter.
