Why Should I Have My Soil Tested?

Definition:

Popular to say, scientifically applying formula fertilizer under the guidance of agricultural science and technology person.Based on soil test and field experiment of fertilizer, according to the law of crop need fertilizer, soil supply capacity and fertilizer effect, and based on reasonable application of organic fertilizer, the quantity, fertilization period and application method of nitrogen, phosphorus, potassium, medium and trace elements and other fertilizers were put forward.A pre-plant soil test will tell you what fertilizers you need to apply to get your plants off to a good start by providing them with proper soil fertility at planting.

Implementation steps：

The technology of soil measurement and fertilization includes five core links and nine key contents，these are: soil measurement, formulation, fertilizer distribution, supply and fertilization guidance by agricultural technological perpons.

Field experiments:

For Beidou‘s subsidiary Tianxuan, we helped farmers to apply soil-tested formula fertilizer for a year, autumn comes, they caculate the output and outcome with their apples.Here I’d like to post some pictures:

Soil testing:

Soil testing is one of the important bases for the formulation of fertilizer. With the continuous adjustment of planting structure and the emergence of high-yield crop varieties, the structure and quantity of fertilization have changed greatly, and the soil nutrient storage has also changed obviously.Through the soil nitrogen, phosphorus, potassium and medium and microelement nutrient testing, understanding the soil fertility status.

Formulation design:

Fertilizer formula design is the core of soil formula fertilization. By summarizing field experiment and soil nutrient data, different areas were divided into different fertilization zones. At the same time, according to the similarity and difference of climate, geomorphology, soil and farming system, and combined with expert experience, the fertilization formula of different crops was proposed.

Calibration test：

In order to ensure the precision of fertilizer formulation, minimize formula fertilizer production and the risk of widespread application, set up in each application partition unit formula fertilization, farmers used fertilizer fertilization three blank, processing, to the local main crops and their main variety as the research object, contrast formula fertilization effect of yield and fertilization parameter, verify and improve the fertilizer formula, technical parameters measured soil fertilizer.

Formula processing：

It is the most important step to improve and popularize the technology of soil formula fertilization in the field.
At present, different regions have different modes, among which the most important and most promising mode of operation is market operation, factory processing and network operation.This mode is adapted to the current situation of low scientific and technological quality, small scale of land management and separation of technology and materials in rural China.

Demonstration and popularization

Publicity and training：
It is an important means to improve farmers’ awareness of scientific fertilization and popularize technology.
Farmers are the ultimate users of the technology of soil formula fertilization. At the same time, we should also strengthen the systematic training of technical personnel at all levels, fertilizer production enterprises and fertilizer distributors, and gradually establish a system of certification for technical personnel and fertilizer suppliers.

Effect evaluation：
Farmers are the ultimate implementers and implementers of the technology of soil testing formula and fertilization, and also the ultimate beneficiaries.To test the actual effect of soil formula fertilization, obtain the feedback information of farmers in time, and constantly improve the management system, technical system and service system.At the same time, in order to evaluate the effect of soil formula fertilization scientifically, a dynamic investigation must be carried out in a certain area.

Technology innovation：
Technological innovation is the scientific and technological support to ensure the long-term effectiveness of soil testing and fertilization.We will focus on innovative research on field test methods, soil nutrient testing techniques, fertilizer preparation methods, and data processing methods, and constantly improve the technical level of soil formula fertilization.
