Humus Management for Healthy Soils & Soil Life
High financial investments are made in climate protection, flood protection, erosion control and costly water treatment. But hardly any attention is paid to the fact that healthy soils are needed!
To secure the future and especially in view of climate change, increasing the humus content of soils and supporting soil life is hardly needed. We have to regenerate the reduced water absorption, storage and filtering capacity and the increased susceptibility to erosion – i.e. the disturbed soil functions – of our soils used for agriculture and forestry.
Wise humus management thus supports the ecosystem services of soils, such as water absorption, water storage and flood prevention.
The production of own manure and fodder via the N-fixation of legumes as well as the reduction of fuel demand during soil cultivation through root loosening with catch crop mixtures and mixed crops reduces energy demand and is climate-friendly.
Together with the use of compost, these measures significantly improve the humus content. Research shows that organically managed soils can bind 2 x more carbon (FAO 2007) and store twice as much water (KBU 2016) as conventionally managed soils. This is because the high humus content promotes soil life and the development of a good soil structure.
Agroforestry systems also contribute to the build-up of humus down to deep soil layers, Keyline Design creates water retention.
