Soil Moisture

Soil moisture is the critical parameter in agriculture. If there is a shortage or overabundance of water, plants may die. At the same time, this data depends on many external factors, primarily weather conditions and climate changes. That is why it is so vital to understand the most effective methods for analyzing soil moisture content.

This term refers to the entire quantity of water in the ground’s pores or on its surface. The moisture content of soil depends on such factors as weather, type of land, and plants. The parameter is vital in monitoring soil moisture activities, predicting natural disasters, managing water supply, etc. This data may signal a future flood or water deficit ahead of other indicators.
