How to improve soil color
The main objective to make your soil healthier is to improve organic matter content of your soil.
It is important to understand that organic matter is a crucial storehouse for nutrients and a major contributor to aggregate formation and stability, playing a central role in ecosystem functioning for all soil types (sandy, clay, loamy and all the ones in between). Soil Organic matter influences fertility and associated (primary or crop) productivity and hydrology (infiltration/runoff rates and flood regimes). It prevents erosion on shallow soils, especially by providing protection against flooding and run-off (soil cover, plant).
You can:
- Add a thick layer of rotted manure, mulch or compost to the soil surface. Even a 5 cm layer added each year will soon significantly increase your soil depth.
- Consider bringing in additional top soil from another site or from another part of your site.
