Soil acidification
Causes of soil acidification. One is that the amount of precipitation or watering is large and concentrated; the second is the long-term application of large amounts of chemical fertilizers. At present, most chemical fertilizers are acidic fertilizers.
Solutions for soil acidification. Pay attention to the application of high-quality organic fertilizer, increase the content of organic matter in the soil, and scientifically apply fertilizer. At the same time, pay attention to the application of microbial bacterial fertilizer and soil conditioner, increase the number of beneficial microorganisms in the soil, and keep the soil fertile.
Soil nutrition imbalance
The reason for the unbalanced proportion of soil nutrients. Crop growth requires 17 essential nutrients. In daily management, we only pay attention to nitrogen, phosphorus, and potassium fertilizers, and ignore medium and trace element fertilizers, which causes the depletion of trace elements in the soil and the accumulation of a large number of elements.
The solution to the imbalance of soil nutrient ratio. â‘ Scientific formula fertilization. According to relevant information disclosed by the Ministry of Agriculture, among the 1.8 billion mu of cultivated land in the country, the area lacking calcium, magnesium and other elements accounts for about 50%, the area lacking boron accounts for more than 40%, and the area lacking zinc accounts for more than 20%. Imperative.
â‘¡ Apply more organic fertilizer. Organic fertilizer can increase the humus of the soil, which is conducive to the formation of agglomerate structure, improve the aeration, water permeability and nutrient status of the soil, and can decompose and release some solidified nutrient elements to supplement the soil.
â‘¢ Apply trace element fertilizer. And crop harvests carry trace elements from the soil year after year, causing the trace elements in the soil to be depleted. Improper use of chemical fertilizers can also lead to antagonism of nutrients and lack of trace elements. Therefore, according to the growth of crops, it must be replenished in time and accurately to achieve a satisfactory harvest.
â‘£ Attach importance to top dressing outside the roots (foliar fertilizer). Foliar fertilizer can accurately and timely supplement the missing elements to the plant, and can effectively alleviate some unnecessary losses caused by the lack of elements.

Fuel monitoring is regarded as an important aspect of fleet management; it will assist fleet managers in reducing the large bite of fuel usage in operations.
Your fleet depends on fuel because you need a monitoring system for tracking and evaluating fuel consumption and expense. Fuel management software is intended to measure and manage fuel consumption in various industries. This is where fuel level sensors step in.
