Weed admixture
Weed admixture refers to foreign materials, including weed seeds and plant debris, present in a grain sample that reduce its commercial quality and storage stability.

In grain handling and storage, the weed admixture percentage is a critical factor for determining market value and processing requirements. It represents everything that is not the target crop, ranging from weed seeds and soil particles to stem fragments.
Effective crop management involves regular monitoring of weed pressure in the field to prevent excessive contamination at harvest. High levels of admixtures significantly increase the risk of spoilage and heating within storage bins, necessitating immediate cleaning or drying.
A common operational error is neglecting primary cleaning procedures after harvesting. Proper calibration of harvesting machinery is essential to ensure that debris levels remain within acceptable thresholds, avoiding unnecessary expenses in later stages of post-harvest processing.
