The difference between commercial organic fertilizer and manure

Commercial organic fertilizers and manure can also supplement organic matter and promote the formation of aggregate structure. However, in terms of green and sustainable development, commercial organic fertilizer has advantages. This is because there are many differences between commercial organic fertilizer and manure.

First, commercial organic fertilizer is “harmless” than manure.

The difference between the two fertilizers is that they are “decomposed” and “harmless”. Manure has many drawbacks compared to commercial organic fertilizers:

Manure

First, it contains more salt and is easy to salinize the soil.

Second, the manure has a large number of germs and eggs, which are most likely to cause pests and diseases in the greenhouse;

Third, the nutrient content of manure is unstable, and it is impossible to make a reasonable fertilizer.

Fourth, if the manure contains harmful substances or heavy metal substances, it cannot be removed only by high temperature fermentation.

Livestock and poultry manure has both a favorable side and a negative side to the soil, and the two aspects can be transformed into each other under certain conditions. The beneficial side of livestock and poultry manure is that it can be applied as fertilizer to farmland fertilizing soil; frequent application of manure can also improve soil resistance to weathering and water erosion, change soil aeration and cultivation conditions, and increase soil organic matter and beneficial microbial growth.

The downside is that excessive use of manure that is not harmless can endanger the quality of crops, soil, surface water and groundwater. In some cases (usually fresh manure) there is a burning phenomenon; the use of a large amount of manure can also cause the accumulation of dissolved salts in the soil, which increases the soil salinity and affects plant growth. According to reports, in 1999, 31% of pastures in Africa caused salinization of soil due to livestock manure contamination, and soil fertility declined.

Second, commercial organic fertilizers improve soils more quickly.

If there is a bad condition in the soil, it is faster to use commercial organic fertilizer to improve than manure.

This is because commercial organic fertilizer has two characteristics of cleanliness and maturity. In the production process, commercial organic fertilizer not only carries out high temperature sterilization and insecticide, but also completely ferments by microorganisms, and controls the oxygen and fermentation temperature well, so that the organic matter is fully decomposed into humus which directly forms agglomerate structure, and at the same time, amino acids and beneficial metabolism are produced. The product was retained. Substances that have an effect on vegetables will not be produced after use.

Again, the ratio of commercial organic fertilizer is more reasonable.

The various nutrients in commercial organic fertilizers are adjustable and can be used with different nutrient content for different soil conditions.
