1. Nutritional needs of crops Scientific formulas must conform to the nutritional needs curve of crops. Since different crop varieties have different nutritional curves, it is necessary to comprehensively consider the fertilizer characteristics of crop types, different varieties, and different growth stages for recommended fertilization.
2. Nutritional absorption capacity, characteristics and regulation techniques of crops Different crop varieties and different bio-regulation techniques can affect the nutrient absorption capacity of crops.
3. Soil nutrient content The soil testing formula is to accurately quantify the basic nutrient content of the specific land, and then combine the various local actual influencing factors to determine the reasonable and effective fertilization ratio, fertilization amount and fertilization method.
4. Fertilization and Fertilization Characteristics of Soil Different soils have different adsorption and release capacities for fertilizers, and the scientific formula should conform to the characteristics of soil fertilizer and fertilizer supply.
5. Nutrient content, quality and cost performance of fertilizers Scientific formulas should be carried out according to specific fertilizer quality, nutrient content and cost performance. The purpose is to enable farmers to reduce costs and increase production and income.
6. Characteristics of fertilizer loss The scientific formula should consider the loss of fertilizer in the environment, the natural loss characteristics of the soil and the chemical reaction after mixing different fertilizers.
7. Release and absorption characteristics of fertilizers The scientific formula should consider the release curves of different fertilizers in the environment and soil and the absorption efficiency of different fertilizers by the same crop.
8. Synergistic technology of fertilizer products Scientific formula should consider the fertilizer utilization rate of different production technologies and synergistic technologies of fertilizers. The efficacy of fertilizer synergists should be fully considered in soil testing and formula fertilization. In addition, some product technologies have obvious characteristics of improving fertilizer utilization, such as bio-conditioning technology, fertilizer synergy technology, integration technology, and small molecules (easy to absorb). Production technology. These can improve fertilizer utilization and save costs.
9. Influencing factors of climate The main climatic factors such as temperature, rainfall and light can affect the absorption of nutrients by crops and the conversion and loss of fertilizers in the soil. Therefore, scientific formulas must consider the effects of environmental climatic conditions.
10. Fertilization methods and means Scientific formulas should consider local fertilization methods and means. The same fertilizer, if the fertilization methods and means are different, the fertilizer utilization rate will be different.
