Pre-harvest moisture content
The percentage of water present in seeds or plant material just before harvest, which determines the timing for gathering crops and their storability.

Pre-harvest moisture content is a critical metric for scheduling harvest operations to maximize grain quality and minimize storage losses. Identifying the target moisture range is essential for reducing mechanical damage to grains and ensuring efficient threshing performance.
Agronomists rely on field moisture sensors to track the drying progress across different zones of the field. Managing this parameter effectively prevents the risks associated with both harvesting high-moisture grain, which is prone to spoilage, and overly dry grain, which is prone to shattering losses.
A common mistake is failing to account for the moisture of weeds and green plant debris, which can drastically increase the total moisture load of the harvested mass. Relying on visual estimation rather than precise measurements frequently leads to improper storage conditions and heat damage in silos.
