Claim 14:
15. One or more non-transitory machine-readable information storage mediums comprising one or more instructions which when executed by one or more hardware processors cause:
estimating bare surface soil moisture associated with bare soil in a geographical area by applying a soil moisture estimation model to a remote sensing derived data, via one or more hardware processors, wherein the remote sensing derived data obtained under no-vegetation condition in the geographical area using a remote sensing technique;
estimating, at a plurality of time-instants, the vegetation surface soil moisture associated with the soil in the geographical area under vegetation cover on the soil, via the one or more hardware processors, wherein the vegetation surface soil moisture at the plurality of time instants computed based on the bare soil moisture, a soil parameter, a weather parameter, a crop parameter, one or more time-series satellite derived remote sensing parameters, wherein the one or more time-series satellite derived remote sensing parameters derived based on optical sensing data obtained at the plurality of time instants;
estimating, via the one or more hardware processors, a point-based root zone soil moisture using a soil water balance model, wherein the soil water balance model computes root zone water balance on a periodic basis based on water stored in the root zone at periodic intervals, and precipitation, irrigation, drainage and evapotranspiration amount of water during the periodic intervals; and
determining, via the one or more hardware processors, spatially distributed root zone soil moisture at the geographical location using the vegetation surface soil moisture and the point-based root zone soil moisture.
