Water and soil fertility are the main factors affecting crop growth. Especially soil fertility plays a decisive role in the growth of crops. Nitrogen fertilizers, phosphate fertilizers, and potash fertilizers are the most common fertilizers. Soil fertiliser detectors are commonly used to determine the content of these elements in the soil to guide fertilization. The soil fertilizer detector can determine the content of available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, etc. in the soil. It is an indispensable instrument for soil component detection experiment, and is sometimes called Soil composition analyzer.

According to studies, there is a certain relationship between adequate soil fertility and the absorption of soil moisture. Sufficient fertility helps better and more effective water absorption and produces more crops per millimeter of water. The soil moisture content can be measured by the soil moisture temperature tester. It can not only measure the soil moisture content, but also measure the soil temperature.
The relationship between soil fertility and soil moisture content can be explained as:
1. Adequate fertility can deepen the root system into the soil. Sufficient fertility will help expand the growth and lushness of the root system. Every 1 centimeter deep into the soil, the root system can obtain 0.85~1.7 mm of water.
2. Most of the phosphorus and potassium diffused toward the root along the water film surrounding the soil particles. In the absence of water, the water film is thin and the distance of ion movement increases. Therefore, the migration of phosphorus and potassium to the root is reduced. Increasing the concentration of phosphorus and potassium in the soil (ie, increasing its concentration in the soil solution) can increase its transport to the root.
3. High soil water suction (low humidity) exerts a physiological influence on the root system. As the suction increases, the length of the root hair decreases, the turgor pressure decreases, and the number decreases. Mitochondrial development slowed, vector concentration and phosphorylation decreased. All of these will reduce the absorption of nutrients.
4. Adequate fertility reduces water demand and transpiration decreases. Potassium has been shown to help close the pores and thus reduce water loss.
5. Increase crowning and speed up soil coverage. This reduces the amount of water that evaporates directly from the soil to the air, and most of it is used by plants. A survey conducted in Georgia, USA, showed that only 35% of soybean fields were covered completely in September. As a result of the test, 69% of the soil in the plot had a pH value of less than 6.9, while the other 39% had a moderately low phosphorus content, and 79% had a moderately low potassium content.
6. Sufficient fertility can accelerate maturation. This is particularly important for corn and helps to ensure pollination before summer drought. Similarly, delayed grain growth of cereals is also adversely affected by summer droughts at heading and thereafter.
7. Increased amount of plant and root debris. Under any kind of farming measures, a larger amount of debris will prevent the impact of raindrops, slow down the flow of water and increase water infiltration. The effects of wind erosion are also reduced by the debris.
Therefore, it is necessary to configure a soil fertilizer detector in farmland operations. It can determine the content of fertilizer in the soil and guide you in fertilizing, so that you can effectively use fertilizer and protect the environment at the same time. for? !
