The cake is fertile, but it must be fermented before it can be used.

Some friends asked whether rapeseed, soybean and peanut meal could be sprinkled directly into farmland as organic fertilizer. Although there was no targeted answer to this question in the article before the scientific development of agriculture, it was also mentioned in the answer to farm manure: it must be mature! There are many parasitic eggs and bacteria in farm manure, and the organic matter in it belongs to organic state, which is not timely and can not be well utilized by plants.

Cake fertilizer is no exception, although cake fertilizer is generally made from the seeds of oil crops, with fewer parasitic eggs or bacteria, but the lactic acid and acetic acid contained in the incomplete cake fertilizer can also cause damage to the roots or seeds of the plant. After fermentation, the organic matter can be degraded into small molecular substances, which is convenient for plant absorption and utilization, fast fertilizer efficiency and high utilization efficiency, and the fermented organic matter can also improve soil biological activity and improve soil structure, which is helpful to increase production.

Having said so much, let's introduce some methods of cake fertilizer fermentation.

Traditional fermentation

Cake fertilizer fermentation, which is often seen in rural areas, is to pile up the cakes and cakes, but mix them well with water. Basically mix 100 jin of cake with 20 jin of water, first mix the cake well, pay attention to not too much water, otherwise it can not be fermented, and too little is difficult to ferment well, it is basically the degree to which the hand is saved into a ball and let go. After mixing, pile the cake into a pile, preferably covered with plastic film, open the film compost and turn it once after an interval of four or five days, until it is not sticky and the color is red, which means it is done.

After fermentation, thinning and drying can be carried out, and storage can be carried out after drying, or fertilization can be applied directly without drying.

Microbial strain fermentation

Now there are some fermentation agents on the market, generally speaking, these strains are screened by biology, and their fermentation efficiency is much higher than that of traditional fermentation. That is, in the process of fermentation, some bacterial agents are mixed in the cake fertilizer to improve the fermentation efficiency. However, the overall operation is basically similar to the above, and it will not be introduced too much here.

The application of cake fertilizer still has to go through ripening, and the unfermented cake had better not be applied to the farmland, not to mention its low efficiency, and some organic acids may also cause damage to plants. Cake fertilizer fermentation production is not troublesome, can be used after ripening, the effect will be better.

Here is science to promote agriculture, welcome to add attention, with you to grow knowledge.
