Soil Moisture Tester for Wheat at Different Growth Stages

In the soil moisture tester's experiment, the ratio of soil water consumption or the remaining amount of soil effective water to the effective water storage before sowing is commonly used in the whole growth period of the crop to illustrate the ability to use the soil water. As already mentioned The reason is that this method fails to reflect the real ability of crops to soil moisture, neglecting the role of soil water storage as “turnover water”, and it is not comparable between different years.

The WUE of the crop's soil water use factor (WUC) is introduced to indicate the degree of utilization of soil moisture. For a given crop, the WUC depends more on the nature of the soil and is a measure of the crop's ability to use the soil's ability to use water. The water consumption of crops reflected in the instrumental tests included soil evaporation, but in general, the consumption of soil moisture during crop growth was mainly produced by crop absorption.

The water loss caused by evaporation below 20 cm and the water content caused by water movement are not as large as the water content of crops due to moisture absorption. Therefore, evaporation and soil water movement do not affect the significance of WUC expression. The use of a soil moisture tester is based on the maximum degree of soil water use under different treatments (determined by soil moisture dynamics).

Soil Moisture Tester calculates the soil water use efficiency of winter wheat in 0~150cm cumulative soil layers based on 0~150cm accumulated soil water storage. The utilization coefficient of soil moisture in 0-150cm soil layer of winter wheat is 0.543-0.799, which means that the maximum water use of winter wheat in 0-150cm soil layer can reach 54.3%-79.9% of the effective water content in field water capacity. From 21.1% to 45.7%, the effective moisture is not available.
