Humus is the basis of soil fertility.
Humus positively influences virtually every soil property.
Spar and WWF Austria are working with farmers to promote healthy soils. Their approach is to focus on building humus by gentle soil-working, observation of crop rotation, and fertilization with compost and manure. Innovative farmers and Frutura suppliers are also lending their support to this project.
Currently some 70 hectares of land belonging to farmers and Frutura suppliers are undergoing conversion or have already been successfully converted; with more to come successively. Each participating farm has signed a written agreement with Frutura in order to take part. The long-term objective is to be able to offer consumers products from verifiable humus sources. The following products are currently sold under a proprietary humus brand: Chinese cabbage, lettuce and tomatoes.
Farmers who successfully build humus are paid a bonus by Spar.
Humus improves plant availability of major and trace nutrients
Humus is important for crumb stability
The higher the humus content, the more water the soil can store
A humus-rich soil can absorb water faster (percolation) because carbon is bound.
Improved crumb stability, water storage and percolation reduce erosion.
