The reason why agricultural experts use soil acidity meter to determine the pH of soil is mainly because there is a close relationship between soil acidity and soil fertility. In fact, soil acidity is one of the important factors of soil fertility, and it is in soil. The existence and availability of nutrients have a tremendous impact on the activity of microbes in the soil and on the plants themselves. Therefore, the pH value of the soil can be measured by a soil acidity meter to understand the soil fertility. Based on this, soil improvement can be performed to ensure the health and growth of the crop.
By measuring the soil acidity meter, we found that when the phosphate in the soil at pH 6.5 ~ 7.5, the soil nutrients the most effective, when the pH exceeds 7.5, due to the formation of calcium phosphate and its fertilizer efficiency, At a pH of less than 6.5, the effect of ferric ammonium phosphate will greatly reduce its effectiveness. Therefore, when the soil acidity meter is used to determine the problem, it is time to take effective measures to regulate it. For example, in the case of nitrogenous fertilizers, nitrification only proceeds most vigorously around pH 6.5. In strongly acidic soils, microbial activity will be limited. Therefore, after lime is applied to acidic soil, it can promote the decomposition of organic matter and the formation of nitrate nitrogen, thus contributing to the growth of crops.
At present, the soil acidity meter has become an important instrument product for agricultural soil testing. Especially when the soil health status is deteriorating, many areas of the arable soil have appeared acidification problems. The use of soil acidity meter to determine To provide scientific basis for the formulation of soil improvement measures and ensure the effect of soil improvement, which will contribute to the improvement of China's agricultural soil environment and the sustainable development of agriculture.
Relationship between Soil Acidity and Soil Fertility Determined by Soil pH Meter
The development of science and technology has brought a series of changes to the agricultural sector. Taking soil acidity testing as an example, agronomists can use the soil pH meter to quickly and accurately understand soil pH conditions!
