The specific standard is to apply 15 kilograms of high-quality organic fertilizer (decayed chicken, pigs, cattle, and other livestock manure) per square meter of projected area of ​​the crown, and 0.05 to 0.1 kg of superphosphate. About 10 tons of organic fertilizer and 35 to 70 kg of superphosphate are needed per acre. When conditions are not available, they can be supplemented by adding them year by year. The organic fertilizer and phosphorus fertilizer were mixed with 5 to 8 times the amount of soil, and were distributed at the same density as the accumulation point. If the soil is heavy, it can be properly mixed with coarse sand when conditions permit. Puyang Linshi Medical Supplies Co., Ltd. , https://www.linshimedicals.com
How to build vineyards to fertilize soil
When constructing a garden, apply as much organic fertilizer as possible. When organic fertilizers are insufficient, do not apply them to the entire park and concentrate on improving the location of planting. Afterwards, expand the scope of fertilization from the planting sites year by year to ensure that the grape roots grow in a good and fertile soil environment.
