Is there a soil testing formula for fertilization in cherry trees?

Is there a soil testing formula for fertilization in cherry trees? Consult cherry tree fertilization can refer to the following: first, fertilizer characteristics of less than 3 years old young trees, should be based on nitrogen fertilizer, auxiliary appropriate amount of phosphate fertilizer. Young trees of 3-6 years old and early fruit stage should pay attention to controlling nitrogen, increasing phosphorus and supplying potassium in fertilization. When the 7-year-old trees enter the full fruit stage, they need to apply more nitrogen, phosphorus and potassium, and supplement potassium fertilizer in the fruit growth stage, which can improve the yield and quality of the fruit. In the process of growth and development, due to the short growth period of cherry fruit, it is characterized by rapid and concentrated need of fertilizer. From leaf spreading, flowering, fruit development to maturity, it is concentrated in April-June, and flower bud differentiation is also concentrated in a short period after harvest. Therefore, attention should be paid to the two key periods of fertilization in autumn and topdressing in spring. 2. Under the medium fertility level of fertilization technology, the amount of fertilizer applied per mu in the annual growth cycle is 2500-3000 kg of organic fertilizer (or 350,400kg of commercial organic fertilizer), 13-15kg of nitrogen, 5-7kg of phosphate and 7-9kg of potash. Organic fertilizer is used as base fertilizer, nitrogen and potassium are divided into base fertilizer and secondary topdressing, all phosphate fertilizer is applied, and chemical fertilizer and farm manure (or commercial organic fertilizer) are mixed. Base fertilizer: the base fertilizer is mainly organic fertilizer, combined with appropriate amount of chemical fertilizer. General mu application of farm fertilizer 2500-3000 kg or commercial organic fertilizer 350,400kg, urea 5kg, diammonium phosphate 11-15kg, potassium sulfate 4-5kg. Topdressing: topdressing at flowering stage: 11-12 kg urea per mu and 6-8 kg potassium sulfate per mu. Topdressing during berry expansion period: 8-9 kg of urea and 4-5 kg of potassium sulfate per mu. Extra-root topdressing: 4-5 times in the whole year, 2 times in the early growth stage, mainly nitrogen fertilizer, and 2-3 times in the later stage, mainly phosphorus and potash fertilizer. 0.3% Mel 0.5% urea, 0.2% Mel 0.3% potassium dihydrogen phosphate, 0.1% Mel 0.3% borax can be sprayed on the leaf.
