REMOTE SENSING TECHNIQUES FOR AGRICULTURAL MANAGEMENT:  REMOTE SENSING TECHNIQUES FOR AGRICULTURAL MANAGEMENT The following factors influence the use of remote sensing in agricultural surveys Characteristics of the agricultural landscape Detection, identification, measurement and monitoring of agricultural phenomena are predicated on the assumption that agricultural landscape features e.g. crops, livestock, crop infestations and soil anomalies have consistently identifiable signatures on the type of remote sensing data. Some of the parameters which may cause these identifiable signatures include crop type, state of maturity, crop density, crop geometry, crop moisture, crop temperature, soil moisture, soil temperature.
