The amount of nitrogen-based fertilizers greatly exceeds the demand for crops. China's arable land accounts for only 7% of the total area of ​​cultivated land in the world. However, in fact, 35% of the world's fertilizer is used, and deformed agriculture needs to “lose weightâ€. While reasonably regulating the amount of chemical fertilizers, the average amount of chemical fertilizers should be reduced as much as possible. Especially for vegetables and some economic crops, it is necessary to strictly control the amount of chemical fertilizers, scientifically and rationally apply fertilizers, and increase the utilization rate of chemical fertilizers.
Accelerate the promotion of balanced formula fertilization techniques and measurement of soil fertiliser detectors to increase fertilizer use efficiency: Scientific and rational use of fertilizers, which is the balanced formula fertilization technology promoted in developed countries, allows experienced experts to determine scientific fertilization schemes for use in chemical fertilizers It is necessary to pay attention to the proportion of fertilizers used, and to calculate the types and amounts of chemical fertilizers applied under the premise of full use of organic fertilizers, so that the proportions of nitrogen, scale, and potassium can be used in coordination to meet the needs of crops.
Blind overdosing of chemical fertilizers has exacerbated the pollution of the environment's chemical fertilizers, reduced the use of fertilizers and reduced the quality of agricultural products, increased agricultural costs, caused an imbalance in the proportion of soil nutrients, insufficient phosphorus and potassium fertilizers, and deteriorated the relationship between soil structure and soil microorganisms. Occurrence of pests and diseases can cause severe crop failure. Therefore, the amount of chemical fertilizers should be reduced. Before fertilization, the content of the fertilizer can be measured by a soil fertilizer detector. The amount needed for calculation is the demand for planting in many projects.
Soil Fertilizer Tester Effectively Improves Chemical Fertilizer Application
With the trend of social and population growth, people's demand for food and some crop products is getting higher and higher. This also makes the amount of fertilizers put into the farmland increase in order to increase production, but the unreasonable amount of fertilizer and excessive application will Soil, water quality, atmosphere, etc. will all bring about certain effects and pollution. Since the use of chemical fertilizers has always been one of the effective measures to increase the yield of crops, all kinds of conditions are basically caused by over-application of chemical fertilizers. In this case, the use of soil should be combined with the continuous updating and development of scientific and technological instruments. Fertilizer detectors of this type can accurately control the amount of fertilizer applied.
