What is 15-15-15 fertilizer?
All fertilizers consist of three numbers with hyphens. This describes the ratio of nitrogen, phosphorus and potassium, also known as the NPK ratio. 15-15-15 fertilizer refers to fertilizers with equal content of each element. The easiest way to think of fertilizer is: chemical fertilizer is plant food.

About Compound fertilizer
(1) Compound fertilizer fertilizer 15 15 15 has long fertilizer effect and is suitable for base fertilizer. A large number of experiments have shown that the base application is better for both binary and ternary compound fertilizers. This is because compound fertilizers contain various nutrients such as nitrogen, phosphorus, and potassium. The early crops are especially sensitive to phosphorus and potassium, and phosphorus and potassium fertilizers are required to be used as base fertilizers and applied early. Controlled-release compound fertilizer adopts coating, granulation and other processes in the production process. The fertilizer effect is slow and stable, and the decomposition is slower than simple chemical fertilizer, the nutrient leaching loss is less, the utilization rate is high, and it is suitable for base fertilizer. Generally, the dosage per mu (667 square meters) is 30-40 kg. Compound fertilizer should not be used in seedling stage fertilizer and middle and late stage fertilizer to prevent greed and youthful growth. Compound fertilizers decompose slowly. For crops that use compound fertilizers as base fertilizers when planting, it is necessary to add quick-acting nitrogen fertilizers in time when topdressing according to the fertilizer requirements of different crops to meet the nutritional needs of crops.
(2) The concentration of compound fertilizer fertilizer 15 15 15 is quite different, so care should be taken to select the appropriate concentration. At present, most compound fertilizers are configured according to the average nutrient status of the soil type in a certain area and the ratio of fertilizer required by crops. There are series of high, medium and low concentration compound fertilizers on the market. Generally, the total nutrients of low concentration are between 25%-30%, the medium concentration is between 30%-40%, and the high concentration is above 40%. Depending on the region, soil, and crops, choose to use economical and efficient compound fertilizers. Generally, high-concentration compound fertilizers are used on economic crops, with good quality, less residue and high utilization rate. The concentration of compound fertilizer is high, so direct contact between seeds and fertilizer should be avoided. Compound fertilizer has a high nutrient content. If it comes into direct contact with seeds or roots of seedlings, it will affect the emergence of seedlings and even burn seedlings and rotten roots. When sowing, the seed should be 5-10 cm away from hole application and strip application of compound fertilizer.
(3) The compound fertilizer ratio is different in raw materials, so attention should be paid to the use range of nutrient components. Different brands and different concentrations of compound fertilizers use different raw materials, and they must be used in production according to soil types and crop types. Compound fertilizer containing nitrate should not be used in leafy vegetables and paddy fields; compound fertilizer containing ammonium ions should not be used on saline soil; compound fertilizer containing potassium chloride or chloride ions should not be used on chlorine-free crops; containing sulfuric acid Potassium compound fertilizer should not be applied in paddy fields and acidic soils. Otherwise, it will reduce fertilizer efficiency and even poison crops. Compound fertilizer contains two or more large elements, nitrogen surface application is easy to volatilize loss or rainwater loss, phosphorus and potassium are easy to be fixed by soil, especially phosphorus has low mobility in soil, and it is not easy to be absorbed and utilized by crop roots when applied to the surface. It is also not conducive to deep rooting. In drought conditions, the fertilizer cannot be dissolved and the fertilizer efficiency is worse. Therefore, the compound fertilizer should be applied deeply and covered with the soil.
