Ten factors affecting fertilizer formula

The scientific formula should conform to the nutritional needs curve of the crop. 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. Fertilizer nutrient content, quality and cost performance

The scientific formula should be based on the specific fertilizer quality, nutrient content and cost performance, in order to reduce the cost and increase production and income.

5. Characteristics of fertilizer loss

The scientific formula should consider the loss of fertilizer in the environment, the natural loss of soil and the chemical reaction of different fertilizers.

6. Release and absorption characteristics of fertilizer

The scientific formula should consider the release profile of different fertilizers in the environment and soil and the absorption efficiency of different fertilizers by the same crop.

7. Characteristics of soil fertility and fertilizer supply

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.

8. 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.

9. Synergistic technology of fertilizer products

The 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.

10. Climate influencing factors

Main climatic factors such as temperature, rainfall and light can affect the nutrient absorption of crops and the conversion and loss of fertilizers in the soil. Therefore, scientific formulas must consider the effects of environmental climatic conditions.
