Formula Fertilization Cannot Overlook Farmhouse Fertilizer
First, the meaning of formula fertilization Formulated fertilization is based on the law of crop manure, soil fertilizer performance and fertilizer effects, based on the application of farmyard manure, put forward the appropriate amount and proportion of nitrogen, phosphorus, potassium fertilizer and trace elements. And the corresponding fertilization technology. It can also be said that formula fertilization is to regulate the supply and demand balance of nutrients needed by the soil supply fertilizer and crops by means of fertilization, to find out the best dosage and suitable ratio, and to truly achieve scientific, rational, quantitative, and time-based. Second, the active ingredient of farmyard manure (organic fertilizer) At present, the amount of nitrogen, phosphorus, and potassium in the formula fertilization refers to the chemical fertilizer, generally does not include the amount of farm manure. However, in order to properly reduce the amount of chemical fertilizers. It is necessary to refer to the choice of formula for various crops. Now briefly introduced as follows: Human urine containing N0.5-0.8%, P2O50.2-0.4%, K2O0.2-0.3%; pig manure containing N0.45%, P2O50-0.19%, K2O0.6%; horse manure containing N0.58%, P2O50.28%, K2O0.53%; burdock manure contains N0.34%, P2O50.16%, K2O0.4%; sheep manure contains N0.83%, P2O50.23%, K2O0.67% Compost includes N0.4%-0.5%, P2O50.18-0.26% and K2O0.45-0.7%; high-temperature compost contains N1.05-2%, P2O50.3-0.82% and K2O0.47-2.53%; Including bean cakes, rapeseed cakes, peanut cakes, sesame cakes, etc. containing N1-7%. P2O50.3-3%, K2O1-2.5%. Third, the content of nitrogen, phosphorus, and potassium per ton of farmyard manure is equal to 25-40 kg of ammonium sulfate. Superphosphate 13-25kg, potassium sulfate 4-6kg; pig excreta equivalent to ammonium sulfate 17kg, superphosphate 21kg, potassium sulfate 10kg; cow excrement equivalent to ammonium sulfate 16kg, superphosphate 16kg, potassium sulfate 3kg; Manure equivalent to ammonium sulfate 28kg, superphosphate 19kg, potassium sulfate 5kg; sheep manure equivalent to ammonium sulfate 3.3kg, superphosphate 31kg, potassium sulfate 5kg, rabbit manure equivalent to ammonium sulfate 86kg, superphosphate 150kg, potassium sulfate 20kg; Pig manure equivalent to ammonium sulfate 23kg, superphosphate 10kg, potassium sulfate 8kg; calves excrement equivalent to ammonium sulfate 17kg, superphosphate 10kg, potassium sulfate 6kg; common compost equivalent to ammonium sulfate 20-25kg, over Calcium phosphate 11-16kg, potassium sulfate 9-11kg. As can be seen from the above, farmyard manure is rich in nitrogen, phosphorus, and potassium, and a small amount of trace elements. In recent years, in Baoqing County, farm manure was neglected in formula fertilization, and only chemical fertilizers were used to fertilize manure. Not listed one by one. Therefore, formula fertilization is based on the application of farmyard fertilizers, using chemical fertilizers to supplement the part of the crop that needs nutrients, in order to ensure increased production and improve quality. Therefore, it is necessary to actively increase farmyard manure in order to maintain the potential of soil fertility, and at the same time it is an important agricultural measure to increase crop yield and quality.
