What is a benefit of digested sludge in agriculture?

Digested sludge is beneficial in agriculture primarily because it provides organic matter to the soil. This organic matter enhances soil structure, promotes the growth of beneficial microorganisms, and improves nutrient availability for plants. Digested sludge, often rich in nutrients and organic content due to the breakdown of organic materials during the digestion process, contributes to soil fertility and improves the overall health of the soil ecosystem.

Incorporating organic materials like digested sludge into the soil can also enhance carbon sequestration and lead to better soil aeration and drainage. This improvement in soil quality can support healthier crop growth and increased agricultural yields over time. The presence of organic matter also plays a key role in the soil's ability to retain moisture, although this specific aspect is a secondary effect rather than the primary benefit of digested sludge.
