Is it possible to increase the nutrient-holding capacity of a sandy soil?
In a home garden setting, the best way to increase a soil’s nutrient-holding capacity is to mix organic matter, such as composted leaves, into the soil. As added benefits, organic matter enhances biological activity within the soil, increases water retention and provides essential plant nutrients. In a field crop situation, green manure (cover crops) can be incorporated into sandy soils to increase nutrient and water retention. To maintain beneficial effects, organic matter must be added to the soil regularly.
