The effect of soil moisture on crops
Soil moisture and its availability to support plant growth are major factors in agricultural productivity. Too little water can cause yield loss and plant death. Too much leads to root diseases and wasted water. Equally important, water is the transport mechanism of any nutrient that is not tightly bound to the soil. . The flow of water in the soil governs how it is transported to the roots of plants. Good water management is important in itself, but good water management also means good nutrient management. Precise control of the root zone environment in terms of water and nutrient content can make crops healthier and higher yields. Soil moisture sensors for agriculture can make irrigation decisions by measuring and observing the trend of push flow over time to help control the root zone environment. If applied correctly, the result can significantly increase productivity and reduce costs.
Soil moisture measurement:
The most accurate method of measuring soil moisture is through weight (measurement. Although it is practical in a laboratory environment, the heavy measurement method is too time-consuming for farm water management. Soil moisture measurement devices can be classified as a device for measuring tension and direct measurement Soil moisture sensors for agriculture. Measuring soil moisture has always played a role in successful farm management. For many years, farmers have relied on the “look and feel” of the soil to assess moisture content. In fact, research shows that experienced farmers can By feeling the soil and visually observing the soil characteristics, certain moisture levels, such as field capacity, can be identified with very high accuracy. However, the soil moisture is continuously monitored at several locations in the root zone, and the information is systematically used to make Irrigation decision-making requires measuring equipment, computers and networked communication equipment.
Types of soil moisture sensors for agriculture
Soil moisture sensors are divided into two categories: soil moisture sensors and soil tensiometers. Each has its advantages and disadvantages. Choose suitable soil moisture monitoring equipment according to different monitoring scenarios.
