Soil nutrient analyzer can solve problems caused by unreasonable application of nitrogen fertilizer
In the process of plant growth, nitrogen fertilizer is usually closely related to its yield. Therefore, the reasonable application of nitrogen fertilizer can increase the yield of vegetables and other crops, but at the same time the unreasonable use of nitrogen fertilizer can also cause some problems, such as the degree of soil compaction and salinization. High, white frost and so on, so to solve these problems caused by the unreasonable application of nitrogen fertilizer, first of all to use soil nutrient analyzer to carry out soil nutrient detection, clear the current soil nutrient structure and content, and then guide the scientific application of nitrogen fertilizer , To achieve the goal of saving costs, increasing production, and increasing farmers' income.
The unreasonable application of nitrogen fertilizer can be divided into two cases, one is the overuse of nitrogen fertilizer, and the other is the nitrogen fertilizer is applied too little, resulting in the lack of nitrogen in the soil. In the soil, nitrogen exceeds the standard, but it causes the vegetable plants to grow indefinitely, and causes the degree of salinization of the soil to increase. The soil compacts, affects the growth of the vegetable roots, and even causes the vegetables to burn out and die, while the nitrogen-deficient soil It can not meet the growth needs of crops, easily lead to slower growth of vegetable plants, flowering fruit set is not good, is not conducive to the production of vegetables.
Through analysis, we found that the main reason for the mismatch between the application of nitrogen fertilizer and plant demand was that farmers did not have testing equipment and did not pay attention to soil fertigation. As a result, soil nitrogen exceeded the standard or was lack of nitrogen. Therefore, in response to this situation, the most effective improvement measure is to use a soil nutrient analyzer to carry out soil testing and formula fertilization. Based on the soil test, according to the law of crop manure requirements, soil nutrient performance and fertilizer effect, scientifically propose organic fertilizers. The application amount of nitrogen, phosphorus, potassium, and trace elements and other fertilizers, nutrient ratio, fertilization time and application method, etc., can not only meet the growing needs of crops, but also avoid unnecessary caused by blind and excessive fertilization. Losses, through improving the utilization of chemical fertilizers, solve the soil problems caused by the unreasonable application of nitrogen fertilizers.
