Organic matter management-returning organic matter to a soil as it is removed-can do wonders to increase and sustain a soil's productivity. All of the properties of a highly productive soil are dependent upon the presence of organic matter: Soil fertility: Organic matter adds plant nutrients to the soil as it breaks down. It also provides ...

Seaweed sinking is a nature-based carbon removal method that involves dropping mature seaweed or kelp at least 1,000 meters under water so that the carbon released upon decay is trapped at the seafloor at immense pressures. Alkalinization, on the other hand, is an engineered solution that sees substances like lime or olivine added to ocean water.

Any organic matter can be a mulch: dried leaves, straw, grass, and (of course) eggshells. This is a far better use of your eggshell resources and actually works as intended. When the shells are crushed and layered on top of the soil around your tomatoes, they perform the same job as any store-bought mulch.
