Fermentation and application of cake fertilizer

Nowadays, cake fertilizer is welcomed by the majority of growers and is often used in greenhouse vegetable crops. The residue of cake fertilizer left after oil extraction from real-time oil crops is a kind of high quality organic fertilizer. The application of cake fertilizer can not only improve the soil, but also improve the quality of crops, but only after fermentation can its nutrients be absorbed. Let's take a look at the fermentation and use of cake fertilizer with the editor.

1. Cake fertilizer fermentation

1. Harm of non-fermentation

The use of cake fertilizer after fermentation can effectively avoid its harmful effects, because cake fertilizer contains organic matter, and fermentation decomposition will produce acid substances such as formic acid, acetic acid, lactic acid and young root development, especially in sandy soil and dry land. After fermentation and application, this phenomenon can be avoided. Some cake fertilizers contain about 10% oil, which decompose slowly in the soil, reduce soil water content and prevent root absorption. In addition, cake fertilizer without fermentation may be due to root burning.

2. Fermentation method

First, mash the cake fertilizer, then accumulate it with compost or stable compost for 2-3 weeks, or mix rotten human and animal feces and urine with broken cake fertilizer, add some water and rett together for 2-3 weeks, pay attention to the proper composting, so as not to attract flies after smelly. Finally, the use of starter fermentation can contain citrus peel and other substances such as limonene, can make the fermentation broth fragrant, cake fertilizer fermentation pile around and the surface should be strictly sealed with wet mud, do not turn over the pile to prevent the loss of ammonium volatilization.

II. Usage

1. Base fertilizer or topdressing

As a base fertilizer, it can be retted directly and applied one week before planting. It is suitable to apply 10-20 cm deep in the soil layer, not directly on the surface, but also fertilize too deep. If it is used as a kind of fertilizer, it must be fully mature, so as not to burn roots to affect the emergence of seeds, or to apply it to the soil together with compost organic fertilizer as base fertilizer, which is safer. When applied as topdressing, it also goes through fermentation, without fermentation, its fertilizer effect is slow, and the best time for topdressing is lost.

2. Application method

Before the application of the plant, we should first dig the planting hole, apply about 100 grams of cake fertilizer in each hole, mix it with the soil evenly and then plant it. This fertilization method can increase the crop yield by about 10% and 20%, and has good commercial quality and good quality. especially in cucumbers and tomatoes. It can also be mixed with base fertilizer, according to crop and soil fertility temperature, low soil fertility and fertilizer-tolerant varieties should be applied more, otherwise, the amount of fertilizer application should be reduced.
