Jharkhand, the state covered with lush green forest has 80% of its rural population earning their primary income from Agriculture. The state practices mono-crop system (Kharif crops), mainly paddy and hence the yield mainly depends on soil moisture1. Soil moisture map of Jharkhand (as on 7th March 2017) shows less soil moisture in the northern part of the state, especially in districts – Giridih, Deoghar, Bokaro, Dhanbad etc whereas Godda, Sahibganji and Pakur shows good soil moisture. As June marks the beginning of the cropping season (sowing) in Jharkhand for Kharif crops, the decrease in soil moisture may be of great concern for the farmers. The problem should be addressed well before it worsens.
The map is prepared by merging data from multiple satellites using the vikleda algorithm.
Some of the applications where soil moisture is useful are:
- Optimal irrigation in farms
- Identify areas being over-irrigated
- Improved flood risk estimation
- Monitor agricultural drought in near real time
- Improved weather forecast
- Analyse the impact of an irrigation project
- Identify the irrigated area by an irrigation source
- Automatic billing of farm based on the actual irrigation
- Estimation of actual evapotranspiration taking place
- Estimation of area getting degraded
