Seed cleaning is the process of removing impurities and unwanted materials from seeds to ensure their quality and viability. This involves separating seeds from debris, such as dirt, plant matter, and other seeds that may not be desirable for planting. Clean seeds are essential for successful agriculture and gardening, as they promote healthy growth and reduce the risk of disease. The cleaning process can be done manually or with the help of machines designed for this purpose. Techniques may include screening, air blowing, and gravity separation. Properly cleaned seeds can lead to better crop yields and more efficient use of resources in farming.
