Crop Residue Management: Importance, Benefits, And Hurdles
Crop residue management (CRM) is a strategy based on reducing the frequency and intensity of tillage operations and increasing the amount of leftover debris from previous harvests. The goal of this management approach is to conserve soil and water quality while providing numerous other ecological and economic benefits.

Water treatment residues (WTR) refer to the sludge that is formed during the production of potable. Water treatment residues comprise typically 3-10% of the conventional drinking water plant throughput, with approximately 90-95% of the waste stream produced at the clarification stage of the water treatment process.
Crop residue management
Target corn residue harvest in fields that you'll be planting corn in next year. Rotate residue harvest among fields so you don't remove residue from the same field every year. Reduce tillage following residue harvest. To add carbon back to the soil, use manure instead of or in addition to commercial fertilizer. Consider winter cover crops.

When left in the field, these residues increase water-holding capacity, control erosion, and add nutrients. They can be tilled back into the same soil. Ex- stem, leaves, stalks, etc. Post-harvest residues. Post-harvest residues are the materials left after processing. These residues are used as animal feed and soil amendments.
Turning desalination waste into a useful resource | MIT …
The rapidly growing desalination industry produces water for drinking and for agriculture in the world's arid coastal regions. But it leaves behind as a waste product a lot of highly concentrated brine, which is usually disposed of by dumping it back into the sea, a process that requires costly pumping systems and that must be managed …
