Advanced estimate of the crop yield is useful in various applications e.g. crop insurance, harvest planning, delivery estimates, etc. Advanced estimate of the crop yield can be obtained by performing the statistical analysis, however, it does not take into account the current ground realities and rely only on the historical data. The satellite remote sensing […]
The Kharif season is approaching its end and the availability of water to crops in Maharashtra using Satellite microwave remote sensing reasonably be quantified. The satellite estimated daily soil moisture is converted into monthly average relative soil moisture for June-September 2017 as shown in the figures. During June, relative soil moisture varies from 0 to […]
In India, 72 % of the farmers hold less than 2 ha of land, out of which approximately two-third has less than 0.5 ha of land, based on the latest available agriculture census (see Figure 1). With more than a lakh farmers falling in this category, the regular maintenance of the farm records (farming type, […]
The satellite soil moisture can provide the estimate of evaporation and transpiration. The information on the evaporation from the land surface and transpiration from plants can be used to enhance the short and medium term weather forecast. The weather forecast would help us in preparing for the calamities like flood and in short-term irrigation planning.
The primary objective of IWMP is to address the issue of soil degradation & moisture conservation in the rain-fed areas of the state. The satellite soil moisture can help in the assessment of the impact of the watershed management programme on agriculture. The availability of long term (before and after the project is executed) soil […]
The flood depends upon the intensity of rainfall and the infiltration (absorption) capacity of soil which is related to soil moisture. The satellite soil moisture provides information on the soil infiltration capacity. A combination of real-time precipitation availability and satellite soil moisture can predict the floods. Based on precipitation forecast and soil moisture data, the […]
A deficit in the available soil moisture for agriculture is termed as drought which results in the lack of crop growth and production. Microwave satellite provides information about the available soil moisture in near real time which is useful for drought early warning. The conventional method of monitoring drought based on crop variables e.g. NDVI […]
Knowledge of higher spatial resolution soil moisture is of paramount importance in agriculture, water resource management, flood, drought, etc. Soil moisture has a high spatial variability due to the variability in soil, vegetation and climate. Soil moisture can be measured using soil moisture sensors, however these measurements are point based and not feasible to cover […]
