The soil testing and formula fertilization touch screen inquiry system can also be called a GIS-based soil testing and formula fertilization intelligent inquiry touch screen machine. From the name of the instrument, it can be seen that this is a touch screen multimedia computer and soil testing and fertilizer application The system instruments that the system combines organically.
The soil testing and formula fertilization touch screen inquiry system is suitable for the query and application of the relevant information of the cultivated soil testing formula. Touch the touch screen according to the prompts to query the soil type, physical and chemical properties, nutrient content, and abundance and lack of soil information of the target arable land, as well as the implementation formula of soil testing formula for various crops, and print the “Recommended Fertilizer Card†to make decisions based on this information. Widely used in grassroots agricultural technology services. These fertilization schemes are not only targeted, scientific, and cost-effective, but also minimize fertilizer waste and protect the environment. It is precisely because of the many contributions that the soil testing and formula fertilization touch screen inquiry system can bring to agriculture. Many experts have experimentally developed this kind of multifunctional instrument.
At present, China's annual average fertilizer utilization rate is only 30%, nitrogen fertilizer utilization rate is generally 30% to 50%, phosphate fertilizer utilization rate is generally 10% to 15%, potassium fertilizer utilization rate is generally 40% to 70%. Fertilizer is an important means of production in agricultural production, accounting for more than 50% of the production investment in the crop production, directly related to the cost and quality of agricultural products. There are many reasons for the low utilization rate of chemical fertilizers, but the amount of fertilization and the proportion of fertilization are unreasonable, which is the main factor.
Soil testing and formula fertilization is based on soil testing and fertilizer field trials. Based on the laws of crop manure requirements, soil nutrient properties and fertilizer effects, based on the rational application of organic fertilizers, nitrogen, phosphorus, potassium, and trace elements are proposed. Fertilizer application amount, fertilization period and application method.
The core of soil testing and formula fertilization technology is to regulate and solve the contradiction between crop demand fertilizer and soil fertilizer supply. At the same time, we need to supplement the nutrient elements needed for crops. What elements will be added to crops will be supplemented with what elements and how much it will need to be supplemented to achieve a balanced supply of nutrients to meet the needs of crops; and to increase the use of fertilizers and reduce the use of crops to increase crop productivity. Output, improve the quality of agricultural products, save labor, save money and increase revenue.
By carrying out soil testing and formula fertilization, the amount of fertilizer and the proportion of each nutrient element in the fertilizer can be reasonably determined, and the utilization rate of chemical fertilizer can be effectively improved. Balanced fertilization technology is a more complex technology, and it is not easy for farmers to master it. Only after materializing this technology can it be realized. One-stop service is measured, matched, produced, supplied, and applied. Soil testing and formulating are performed by specialized departments. Fertilizer companies produce and supply farmers according to formulas, and agricultural technicians direct scientific applications. In order to further accelerate the development of agricultural informatization, better serve the development of agriculture, farmers, and the rural economy, and truly serve agriculture and farmers, the “touch-inspection system for soil testing and formula fertilization†was introduced.
