Soil color varies due to natural and anthropogenic factors. The field to field distinction is possible mainly because of anthropogenic factors (espeically the dark tone / color as compared to the next or adjoining fields) including burning of crop residue, application of fertilizers, silt application and the status of the field (crop grown – fallow / current, ploughed / unploughed), with crop or without crop, irrigated / unirrigated etc.
