The key factors that you need to notice when you choose the equipment: fermentation method, organic raw material, mechanization degree, and the annual output. The inherent quality of organic fertilizer is mainly depends on the fermentation and the formula of products. The key factors of fermentation are microorganism, carbon-nitrogen ratio, carbon-phosphorus ratio, moisture, pH value and aeration control. If the one kind of factor can not control well, that will cause unfermented, incomplete fermentation or need long time fermentation. The formula of organic compound fertilizer is also different from the inorganic fertilizer according to the different soil and crop formula. If it can have the properly formulated, the effect is better than the inorganic fertilizer, and has the lower cost, as the green fertilizer, it can also improve the environment of plant survival and the agglomerate of the soil.
Organic manure has the advantages of high nutrient content, less side components and good physical properties. These advantages play an important role in improving fertilizer utilization, balancing fertilization and promoting high and stable yield of crops. However, the proportion of nutrients is always the same in different soil and different crops. Therefore, it is best to measure soil before use the fertilizer, to understand the texture and nutritional status of the soil in the field, and to pay attention to the application of the unit fertilizer in order to make the best effect.
