What are the advantages of the combination of organic fertilizer and chemical fertilizer produced by organic
fertilizer equipment?It is scientific decision to combine chemical fertilizer with organic fertilizer processed by organic fertilizer production line.This is determined by the properties and characteristics of organic and chemical fertilizers.The characteristics of organic fertilizer and chemical fertilizer are compared and analyzed as follows:
1.Most of the high-quality organic fertilizers contain a lot of organic matter.The application of the high-quality organic fertilizer production equipment to process and produce the organic fertilizer all the year round can not only increase the content of soil organic matter,but also make the soil organic matter continuously upddated,so as to improve the physical and chemical properties of the soil,so it has a significant role in soil improvement:while the chemical fertilizer does not contain organic matter,generally there is no direct soil improvement.This shows that organic fertilizer is the basic material for the construction of high and stanle yield farmyard.
2.There are many kinds of organic fertilizer,which contains all kinds of nutrients.People often call it complete fertilizer,but the nutrient content of the organic fertilizer processd by the organic fertilizer production equipment is very low,about 1000 kg of high quality stable manure only contains 5 kg of nitroge;while the nutrient content of chemical fertiilizer is high,for example,100 kg of urea contains 46 kg of nitrogen,calculated by 1000kg,contains 460 kg of nitrogen,which it can be produced in the npk fertilizer manufacturing process.However,the disadvantage of chemical fertilizer is that it contains a relatively single variety of nutrients.Take urea as an example,it only contains nitrogen in the three elements of nitrogen,phosphorus and potassium,and does not contain phosphorus and potassium,while superphosphate only contains phosphorus,does not contain nitrogen and potassium,and single application can not meet the needs of crops.
3.Most of the nutrients in the organic fertilizer are organic,which can be absorbed and utilized by crops only after the continuous decomposition of soil microorganisms.Therefores,the fertilizer efficiency of the organic fertilizer processed by the
organic fertilizer production line is slow,but it lasts for a long time,and has aftereffect.Most of the nutrients in the chemical fertilizer are water soluble,which can be directly absorbed and utilized by crops.Therefore,chemical fertilizer can provide more nutrients when crops need nutrients most,but its fertilizer effect is short and cannot last.It can be seen that rational application of chemical fertilizer is the material guarantee to improve the per unit yield of crops.
4.Organic fertilizer needs to be decomposed and transformed to release nutrients for crops to absorn.Therefore,the utilization rate of organic fertilizer processed by organic fertilizer production equipment is not high in the current season.For example,the nitrogen utilization rate of the rotten organic fertilizer is only 20%-30%,but when it decomposes,the nutrient loss is less,and the fertilizer supply time is long;while the nutrient content of the chemical fertilizer is high,most of which is available nutrient,which is easy to be lost through volatilization,leaching(especially nitrogen fertilizer),so that the fertilizer utilization rate is not high in the current season.For example,the utilization rate of nitrogen is generally about 35%,which of phosphorus is about 10%-25%,and that of potash is over 40%.
Through the comparsion of the two,it is not difficult to see that the organic fertilizer and the chemical fertilizer processed by the organic fertilizer production equipment have their own advantages and disadvantages of the chemical fertilizer which can be produced in the
npk fertilizer manufacturing process,while some advantages of the chemical fertilizer are the disadvantages of the organic fertilizer.Therefore,they can learn from each other and give full play to their own characteristics.This is the necessity and scientific principle of the combination of the two.
