Fertilizer plays an extremely important role in agricultural production, which can increase crop yield by more than 30%. However, the more important the fertilizer is, the more widespread the blind fertilization phenomenon is. Some farmers do not know what nutrition elements are needed in the process of crop growth. They apply fertilizer in accordance with the general trend, apply what others apply, apply what they apply, apply how much others apply and how much they apply... The wrong fertilization method not only restricts the increase of crop yield, but also directly affects the economic benefit of agriculture.

Based on soil testing and fertilizer field experiments, according to the law of crop demand, soil fertilizer performance and fertilizer effect, on the basis of rational use of organic fertilizer, the appropriate proportion and amount of nitrogen, phosphorus, potassium and trace elements, as well as the corresponding application technology (including application time and application method) were proposed.

The soil testing formula fertilization mainly focuses on soil testing, formula, fertilizer allocation, fertilizer supply, fertilization guidance five links to carry out the work. Commonly speaking, soil testing is to find out the soil bottom, understand what is missing in soil nutrients, and conduct regular physical examination for soil, so as to find the right remedy for crop diseases. With fertilizer is a delicious recipe for nutrition, what the lack of soil to fill what. How many fill how many, the most economic, the most cost-effective, but also the most delicious!

The significance of carrying out soil testing formula fertilization

1. Balance soil nutrients and improve crop yield.

Crop growth and development needs 16 kinds of nutrition elements. Carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, manganese, zinc, iron, molybdenum, copper, chlorine.

The first 6 kinds of nutrient element crop demand is large, call large element. Carbon, hydrogen, and oxygen are available from water and air and generally do not require supplementation; Nitrogen, phosphorus and potassium crops need more, but the available nutrients in the soil are less, often need to add fertilizer to supplement, known as the three elements of crop nutrition or fertilizer three elements; Calcium, magnesium and sulfur are medium nutrient elements. Boron, manganese, iron, zinc, copper, copper, chlorine 7 nutrients crop demand is very low, and the content of soil is very low, known as micronutrient elements. These elements of feng, lack of relations with the stand or fall of crop growth and development and production of high and low, so before fertilization on the nutritional status of the existing soil should have a comprehensive understanding, to know what we are planting soil nutrient elements, and the lack of nutritional elements, that kind of fertilizer fertilizer should be applied in calculated according to the expected yield, use how much, this is to be measured soil fertilizer use.

2. Reduce agricultural costs and reduce fertilizer loss.

In production, farmers often blindly apply fertilizer, resulting in uneven distribution of fertilizer and incorrect reimbursement of soil nutrients, resulting in waste of fertilizer. By measuring the soil formula fertilization can be targeted to determine what kind of fertilizer to apply, how much to apply, reduce the loss of fertilizer, reduce agricultural costs, protect the environment, reduce pollution. Make the fertilizer in the soil be absorbed and utilized by the crops as much as possible. It is very beneficial to the protection of agricultural ecological environment.

3. Improve the quality of agricultural products.

The overall quality of agricultural products is not high and unreasonable fertilization has a great relationship, especially partial application of nitrogen fertilizer, potash fertilizer does not aggravate the occurrence of disease.

Vegetable nitrate content is high, not resistant to storage; The fruit becomes sour, the skin thickens, the color and some quality index reduce and so on, these tests soil formula fertilization can solve, tests the soil formula fertilization can provide the crop to need the nutrition comprehensively.

Solve the problem of crops, improve the yield and quality of agricultural products, and naturally improve the income of farmers, improve farmers' lives, and harvest!
