Organic fertilizer is an import source of fertilizer in agricultural production.Its nutrients are comprehensive and the balance of fertilizer efficiency is long-lasting.It can improve the soil structure,improve the soil fertility,promote the release of soil nutrients,but also supply and improve crop nutrition.It has the advantages of chemical fertilizer that can not be replaced.It is of great sigificance for the development of organic agriculture,green agriculture and pollution-free agriculture.Organic fertilizer can not be applied blindly because of the variety of raw materials,great difference in properties and different functions.It should be used scientifically according to the amount.Special attention should be paid to the following points in application:
1.Organic fertilizer contains more  comperhensive nutrients,but it is not balanced and can not fully meet the different needs of various crops for nutrients.Compared with chemical fertilizer with single nutrient,organic fertilizer contains more kinds of nutrients,but its nutrient content is low,and there is imbalanced fertilization.Mineral fertilizer should be applied even in the farmland where green food is produced growth and development of crops.
In the organic fertilizer manufacturing process,the organic fertilizer and inorganic fertilizer powder can be mixed and stirred before the granulation stage for granulation of organic compound fertilizer.The two in one granulator developed by our company is suitable for the mixed granulation of organic compound fertilizer.It uses the high-speed roating mechanical mixing force and the resulting aerodynamic force to make the fine powder continuously mixed and granulated in the machine,so as to achieve the purpose of granulation.The size of particle diameter can be adjusted properly by material mixing amount and sindle speed.The lower the mixing amount is,the higher the speed is,and the smaller the particle is.
2.The effect of organic fertilizer is low.Organic fertilizer is not only low in total nutrient content,but also slow in fertilizer efficiency.When the application amount of organic fertilizer is not large,it is difficult to meet the needs of crops for nutrient elements.Therefore,we should take advantages of high nutrient content and rapid fertilizer efficiency of chemical fertilizer,combine the organic fertilizer with chemical fertilizer,take advantages of combination of crops.
3.Organic fertilizer needs to be fermented by using the organic fertilizer machine.Many organic fertilizers contains pathogens,insect eggs and weed seeds.Some organic fertilizers contains organic compounds that are not conducive to crop growth.Therefore,organic fertilizers should be composted,fermented and processed before application.The mechanical tossing of fermentation raw materials by the compost tossing machine ensures that the raw materials are uniformly and fully fermented and the fermentation quality is guaranteed. The organic fertilizer production line will process the compost after fermentation into fertilizer particles which are easy to apply, green and harmless, and have a long-lasting balance of fertilizer effect. Plants can continuously absorb nutrients in the soil and avoid soil salinization and caking. Fertilizer production equipment plays an important role in the quality of organic fertilizer products.There,by the way,if we make organic fertilizer granulator,the fertilizer granulator machine is necessary.The rotary drum granulator machine is to be equipped in organic fertilizer production line to make organic fertilizer granulator.
