A method of assessing the humidity or moisture content of crop is provided for an agricultural harvester for use during harvesting operations. The method involves harvesting a field using a harvesting machine equipped with a moisture sensor for monitoring the moisture content of the harvested crop and a mass flow rate sensor for monitoring the mass flow rate of crop material in the harvesting machine. The raw moisture data derived from the signal of the moisture sensor are combined with the mass flow rate data for establishing the actual moisture content of the crop material. This moisture data can be used to establish a moisture content map for the field, which has the advantage of identifying field spots with weed infection.

[ Having thus described the invention, what is claimed is:] [1.] A method for assessing the humidity of a crop during harvesting operations, comprising the steps of:harvesting a field using a harvesting machine which includes:a mechanism for collecting crop from the field and feeding it into said harvesting machine;a mechanism for processing said crop fed into said harvesting machine;a moisture sensor for monitoring the moisture content of the collected crop and generating a signal; anda mass flow rate sensor for monitoring the mass flow rate of crop material in said harvesting machine and generating a signal;logging data from said moisture sensor and said mass flow rate sensor while harvesting the field; andderiving the actual moisture content of the collected crop from the combined data from said moisture sensor and from said mass flow rate sensor by the substeps of:monitoring the signal from the moisture sensor and deriving therefrom a raw moisture content value;monitoring the signal from the mass flow rate sensor and deriving therefrom a mass flow rate value; andadjusting the raw moisture content value inversely proportionally to the mass flow rate value to obtain the actual moisture content value by dividing the raw moisture content value by a factor.
