Soil is the main material basis for plants to survive and can provide crops with the necessary water, fertilizer, heat, and air for growth. This is mainly because the composition of soil includes organic matter, minerals, soil air, and soil moisture, microorganisms, etc., Minerals are the most basic substances that can provide a variety of nutrients to plants. Organic matter can not only provide nutrients to plants, but also play a very important role in improving soil aggregate structure and physical and chemical properties, as well as water supply, water retention, temperature stabilization, and ventilation. What parameters can the soil sensor soil detector detect and what are the functions?
The monitoring of soil moisture
Less soil moisture will directly (reduce photosynthetic raw materials) or indirectly (stomata closure, enzyme inactivation, etc.) affect the decline of photosynthesis, and become a large limiting factor for photosynthesis. The lack of water can also cause crop death, because the total volume of soil gaps is a certain amount, and this part of the volume is occupied by water and air. Then when the water is too low, the water absorbed by the root system of the plant is insufficient, and the transpiration of the plant causes the plant to lose a lot of water, which leads to the loss of wilting of the plant. The root system is broken, and in severe cases, the plant will die. When there is too much water, the proportion of air is small, resulting in weakened aerobic respiration of plant roots, and plant roots are forced to turn to anaerobic respiration.
To monitor soil moisture, soil moisture sensors can be used to timely decide whether to irrigate or stop irrigation through data to ensure that soil moisture is suitable for crop growth.
The monitoring of soil temperature
A suitable soil temperature is conducive to the growth of plants, and a temperature that is too low or too high is not conducive to the growth of plants. The seeds of crops can only germinate within a suitable soil temperature range. Within a certain temperature range, the higher the soil temperature, the faster the growth and development of crops. Different plants have different requirements for temperature.
The soil temperature is monitored by the soil temperature and humidity sensor so that the soil temperature is kept within the suitable growth temperature range of crops, so as to ensure the increase of crop production and income.
3. Monitoring of soil pH
The growth of various plants has its own suitable soil acidity and alkalinity, and most plants are difficult to grow normally when the pH is too high or too low. Some diseases can only occur in a certain pH range, such as damping off, which tends to occur on alkaline and neutral soils. The soil pH is detected by the soil pH sensor. Appropriate soil pH is helpful for the growth of agricultural crops and reducing pests and diseases, so the monitoring of soil pH is very necessary.
4. Monitoring of soil nitrogen, phosphorus and potassium
Nitrogen is the main component of protein, plays an important role in the growth of stems and leaves and the development of fruits, and is the most closely related nutrient element to yield. The uptake of nitrogen by the plant increases gradually before the first ear of fruit expands rapidly.
Phosphorus fertilizer can promote tomato flower bud differentiation, early flowering, and fruiting, promote seedling root growth and improve fruit quality. When phosphorus is deficient, young shoots and roots grow slowly, plants are short, and the leaves are dark green, dull, and purple on the back.
Potassium can promote the robustness of plant stems, improve fruit quality, enhance plant cold resistance, and increase fruit sugar and vitamin C content. Like nitrogen and phosphorus, potassium deficiency symptoms first appear in old leaves. When potassium supply is insufficient, carbohydrate metabolism is disturbed, photosynthesis is inhibited, and respiration is enhanced. Therefore, when potassium is deficient, the plant’s ability to resist stress is weakened, and it is susceptible to disease attack, and the fruit quality is reduced and the coloring is poor.
Soil NPK Sensor
The soil nitrogen, phosphorus, and potassium sensor can detect the content of nitrogen, phosphorus, and potassium in the soil to provide the necessary nutrients for plants and promote their growth of plants.
Soil is the most important substrate for crop growth. Crop roots need to absorb nutrients and water from the soil in order to grow normally. Soil conditions directly affect crop yield. Therefore, for agricultural practitioners, only accurate and sufficient soil Soil quality data can be targeted in the process of irrigation and fertilization and provide a better growth environment for crops.
For smart agricultural projects, soil comprehensive sensors are extremely important basic equipment. Although the demand varies according to the area of the planting area, the demand is relatively large.

This five-pin soil comprehensive sensor launched by Jingxun Changtong can measure soil temperature, humidity, Ph value, electrical conductivity, nitrogen, phosphorus, and potassium content in real-time, five factors that have a greater impact on crop growth. Data, LoRa, NB-IoT, and 4G are uploaded to Jingxun Cloud IoT cloud, users can log in to Jingxun cloud intelligent agricultural management platform to view through mobile phones and computers. Favor has achieved breakthroughs in monthly sales many times this year, and the monthly sales exceeded 2,000, showing strong market competitiveness.
Soil moisture monitoring takes farmland as the object and establishes monitoring stations in different ecological and climatic regions according to different planting patterns and adopted agricultural technologies. Through fixed-point and regular measurement of meteorological factors such as soil moisture and precipitation, as well as observations and records of agricultural production management, crop appearance, etc., the soil moisture status and soil effective moisture content of the active layer of crop roots can be timely understood.
The first is to reflect the current water demand and soil water utilization status of crops, and to understand whether the crops are affected by insufficient soil moisture and affect planting or normal growth, so as to determine agricultural operations such as irrigation, fertilization, and sowing;
The second is to reflect the relevant laws of atmospheric drought and soil drought, understand the trend and degree of drought disasters, and put forward drought early warning forecasts;
The third is to reflect the regulatory effect of different agricultural technologies on the storage, preservation and use of soil moisture and their impact on crops, and provide support for the scientific popularization and application of water-saving agricultural technologies.
Fourth, by accumulating long-term soil moisture monitoring data for many years, master the changing laws of soil moisture in different regions, soil types, and application conditions of different technology models, and combine the analysis of meteorological and hydrological data in various places to improve the regional soil moisture classification and early warning system, explore Prediction of soil moisture changes.
