Direct harvesting
A harvesting method where cutting and threshing of crops are performed in a single pass of the combine harvester across the field.
Также говорят: direct combining, single-phase harvesting
Direct harvesting is the most efficient and widely used method for collecting cereal and grain crops. By combining mowing and threshing into one operation, farmers significantly reduce the time required for harvesting and decrease the number of machinery passes, which helps to minimize soil compaction.
This method is typically used when crops have reached full maturity and have uniform moisture content. Crucial factors for successful implementation include clear field conditions and minimal weed presence, as high weed density can impede machine efficiency and raise the moisture level of the harvested grain.
Common mistakes include attempting to harvest before the crop is sufficiently dry or harvesting in weed-heavy conditions, which often results in machine clogging, increased grain damage, and higher post-harvest energy costs for drying and cleaning the grain mass.
