In recent years, due to the excessive use of pesticides and fertilizers, the soil fertility decline is very serious, and the soil fertility declines, the direct consequence is that the quality of grain yield declines. Therefore, taking effective measures to assess and enhance soil fertility has become an important factor in improving agricultural productivity. content. At present, many areas are very good at quality and safety of soils. Soil fertility testers are actively used to carry out soil nutrient testing. Through scientific testing, data are used to assess soil fertility status, and data for scientific improvement is provided. Soil is the basis of crop growth and the basis of agricultural production. Therefore, from the root cause, improving soil fertility is of great significance to the development of agricultural production and the increase of yield per unit area. In the face of the current unsatisfactory soil quality and safety status, the use of soil fertility testers for on-site testing to investigate the quality of cultivated land and soil fertility is the first and most important step. The soil fertility tester can accurately determine the nutrient content of nitrogen, phosphorus and potassium in the soil, save the data, and use the data to assess the soil fertility status, which is more reasonable and scientific. Not only that, through the data of these measurements, we can also know the current profit and loss of each nutrient in the soil, combined with the characteristics of crop growth, we can formulate a reasonable and effective fertilizer distribution scheme, so as to achieve targeted fertilization, so as not only can avoid fertilizer waste. Reduce the cost of agricultural production, but also improve the production capacity of crops, improve soil water and fertilizer capacity, and lay the foundation for agricultural production and efficiency. The improvement of soil fertility is the foundation of agricultural production development. The improvement of soil fertility, excellent crop quality and scientific and rational farming habits are important factors for agricultural high yield. In the face of the problem of soil fertility decline, we should first pay attention to it, followed by scientific improvement and improvement, and use scientific instruments such as soil fertility tester to continuously improve soil fertility, thus promoting the sustainable development of agricultural production. Shrink Wrapping is a process that involves the application of temperature sensitive films. When heat is applied to the film it shrinks tightly to whatever it is covering. Shrink wrapping equipment is available for a variety of product sizes and in both automatic and semi-automatic formats. At Wanfeng Packaging, we can help you find the right shrink wrap machines that are tailored to your operation`s unique needs.
