What does rotting of organic fertilizer mean? Why is it rotten?

Organic fertilizer refers to the process of converting waste organic matter into fertilizer through the fermentation of microorganisms under artificial control and certain moisture, C N and ventilation conditions. Through the composting process, the organic matter is transformed from an unstable state to a stable humus substance, and its compost products do not contain pathogenic bacteria, weed seeds, and are odorless and fly-free, which can be safely handled and preserved, and is a good soil conditioner and organic fertilizer.

There are two main meanings of fermentation:

1. Kill pathogenic bacteria, grass seeds, etc.

2. Through the process of mineralization and humification, the organic matter is converted into substances that are easily absorbed by plants. It also improves the texture of the soil.

Undecomposed organic fertilizer carries a large number of pathogenic microorganisms and parasitic roundworm eggs, and after being applied to farmland, some of them attach to crops to cause direct pollution, and some of them enter the soil to cause indirect pollution. In addition, after the undecomposed organic fertilizer is applied to the soil, it can be absorbed and selected by the crop after self-fermentation, on the one hand, it produces high temperature to cause the phenomenon of burning seedlings, and it will also release ammonia gas to make the plant grow poorly, therefore, it must be fully decomposed when applying organic fertilizer.

The standard of decomposed organic fertilizer is: the color is brown or gray-brown, the temperature of the fermentation product drops below 35 degrees, there is no odor, and there is a faint smell of ammonia.

Qualified organic fertilizer is made of livestock and poultry manure and other organic waste materials after full fermentation and decomposition, fermentation or not, and the way of fermentation, the degree of fermentation and decay determines the quality of the organic fertilizer generated.

The root system of crops is an important way to absorb nutrients. The root system can absorb nutrients in gaseous, ionic, and molecular states. Ionic nutrients are the main form of uptake by plants.

After the fresh organic fertilizer is applied to the soil, the organic nutrients contained in it can not be absorbed and utilized by the crop immediately, and after the unrotted organic fertilizer is applied to the soil, the organic fertilizer contains pathogens, insect eggs and weedy seeds, and produces high temperature and organic acids in the process of decaying, which seriously hinders the normal growth of crops. Therefore, organic fertilizer must be completely decomposed before it can be applied.

Qualified organic fertilizer is made of organic waste materials such as livestock and poultry manure after full fermentation and decomposition, fermentation or not, and the way and method of fermentation, the degree of fermentation and decay determines the quality of the organic fertilizer generated. The simple methods of judging are:

It is possible to see the colors with the eyes. The organic fertilizer that is only dried by pure physical methods still maintains the color of the original manure, but the moisture is reduced, and the composting technology is treated, especially after high-quality fermentation auxiliaries, such as the use of Gymboree type 1 fermentation auxiliaries, the organic fertilizer after fermentation and decomposition, the color of the finished product becomes brown or black-brown, and there are no other impurities in the finished product.

It can be touched by hand. High-quality organic fertilizer is grasped by hand, and its feel is consistent, soft and elastic when wet, brittle when dry, and easy to break, while low-quality organic fertilizer can touch impurities such as sand with your hands. It can also be judged by blisters.

Soak two kinds of high-quality and low-quality organic fertilizer in clean water, and after a few minutes, you can see that the high-quality organic fertilizer is evenly distributed in the water, while the bottom of the container of low-quality organic fertilizer will sink into a lot of sand or soil, and the difference is obvious.

The above opinion is correct, and it is true that we in the fertilizer industry say so.

1 is taste 2, and it depends on the degree of rot of its appearance.

4 kinds of judging techniques for fermented organic fertilizer to be fully decomposed.

If it is not rotted, a large amount of heat will be emitted during use, resulting in the burning of seedlings, and there are toxic gases in the organic fertilizer that is not rotten, which will also be harmful to crops.

Organic fertilizer is used in the process of decomposing for a long time, and it is easy to ferment and rot when it encounters a certain amount of moisture and temperature, which will release a lot of heat, which is easy to cause root burning.

If it is not completely decomposed, heat will be released during the fermentation and decay of organic fertilizer, resulting in seedling burning.

The organic acids secreted by microorganisms in the life activities of fission can dissolve phosphate and nitrate in the soil, release the phosphorus, potassium and trace elements stored in the soil to be fixed, increase the availability of soil nutrients, promote the formation of aggregate structure in the soil, eliminate compaction, improve soil water, fertilizer, gas and heat, and enhance soil fertility. The so-called balanced fertilization and soil testing formula, what is lacking, what can be supplemented, and how it can be fully absorbed and utilized, is judged by the secretion and release of elements in the soil by the action of microorganisms.

<> fertilizer decomposition generally refers to the process of manure, that is, the use of materials that can provide plant nutrients, such as human and animal manure, soybean cake, bellflower, etc., through the process of brewing, fermentation, and decomposition, to form fertilizer that can be absorbed and utilized by plants. After decay, there are few eggs and a lot of nutrients in the farmyard fertilizer, which can ensure good crop growth.
