The total energy uptake in the mill was higher than in the texture analyser, but of the same order of magnitude and with the same relation with the moisture content.
Moisture content continued to decrease and after 3 weeds of field-drying it was less than 20%, and after 6 weeks it was down to 15.2%. At Farm Suwan the moisture content was below 22% after just 1 week, and after 2 weeks of field-drying it was at 19.4%. The moisture content seemed to stabilise at about 17% after the fourth week.
