Why need PH soil sensor?

The influences of soil pH on plants

Plants grow normally over a wide range, but plants have their own proper pH. PH value of most plants grow normally around 7.0. Most plants are difficult to grow at pH> 9.0 or <2.5.

Therefore, the actual production should pay more attention to changes in pH of soil to take a scientific and rational means to actively control the soil pH, soil buffer to improve performance.

measure the significance of soil pH value

· The effect of soil pH on nutrient availability. Such as: nitrogen in 6 to 8 highly effective, because less than 6, Azotobacter activity decreased, while greater than 8, the nitrification was inhibited; Phosphorus 6.5 to 7.5 in the high availability. The availability of calcium and magnesium is best at pH 6-8; borates are more effective at pH 5-7.5.

Plant pests are directly related to soil pH. Underground pests often require a certain range of pH environmental conditions, such as bamboo locust like acid, beetle like alkali. Some diseases only occur within a certain pH range, such as damping-off disease often occurs in alkaline and neutral soil.

· Proper use of fertilizers. Based on the application of organic fertilizer, fertilizers should be rationally applied according to the degree of acid, alkali and soil fertility.
