Soil moisture measurement
The water particles held in the gaps between the soil molecules are called soil moisture, as per soil science terminology.
Measuring this moisture is important, because it helps in
1. irrigation scheduling,
2. estimating crop yields,
3. and reservoir management.
Soil moisture measurement gives us an idea about soil erosion, slope failure, and the quality of the water. It also gives early warning of droughts and floods. It helps to control water evaporation and heat energy released through plant transpiration between the soil surface and the atmosphere. It is a potent variable in the downfall of water and the development of weather patterns. Agencies and companies, that are concerned with water and weather, use soil moisture equipment for measuring and monitoring.
in the process of making clay hence required moisture absorber to absorb water content in soil.
