How to make organic fertilizer

Organic inorganic compound fertilizer is a compound fertilizer containing organic matter and inorganic nutrients. Most of the organic materials are processed organic fertilizers (such as animal manure, municipal waste organic matter, sludge, straw, wood chips, food processing waste, etc.) and organic matter (charcoal, weathered coal, lignite, humic acid, etc.), and some add microbial funguses and stimulate the growth of the material, called organic active fertilizers or biologically slow-acting fertilizers.

Straw to make organic fertilizer

Fertilizer material preparation (1) 100% crop straw (corn stalks need to be roughly crushed, wheat straw can be used directly). (2) "Kendall Green" special rapid fermentation bacterial agent 0.1%. (3) cottonseed cake or soybean cake powder 1-2% (no cottonseed cake, soybean cake powder can be used urea 0.5-1% or 10-20% of human feces instead).

3, the technical points of fertilizer (1) drink enough: the crop straw must be fully watered. Fresh crop straw depending on its degree of wet and dry can be less watering or no watering. (2) Mix well: mix the cake powder with special fast fermentation bacterial agent, and then evenly spread on the surface of straw after watering. Use shovel and other tools to turn over and mix evenly, and pile up into a long strip of 2 meters wide and 1 meter high. (3) cover tightly: in order to retain water, fertilizer, heat preservation, rain, will be mixed evenly with the straw immediately with a plastic cover tightly.

4, straw decay process from the straw pile temperature change can be roughly divided into the following stages: (1) warming stage. That is, from room temperature to about 50 ℃ stage, generally only 1 day. (2) High temperature stage. That is, from 50 ℃ to 70 ℃ stage, generally only 2 days. (3) Cooling stage. That is, the sustained high temperature for 1-2 weeks, began to cool down. At this time, the straw fertilizer process is basically complete, dry or not dry can be used directly in a variety of crops as a bottom fertilizer.
