Many soils are suffering from a lack of organic matter. Farmers and growers often want to maintain or enhance soil organic matter (SOM) content as this can have a range of benefits for soil health. However, recent work has shown that, where improved soil quality is concerned, not all forms of organic matter are equal. Given that applying bulky organic matter has a financial cost, it is important to understand the merits of different organic materials.
This GREATsoils case study considers the benefits of the application of compost to soils and the impact on soil health.
