Mixed green manure
Plants are essential for the soil biology. As soon as possible after harvesting our organic bulbs, we sow a green manure mixture, plants that improve soil fertility.
Every plant secretes certain substances by its roots. These substances feed the microbes in the soil which results in a collaboration between beneficial funghi and plants. If these mycorrhizal funghi are given the chance to grow, they form networks in the soil that protect and support the plants in essential processes during their growth.
Each type of plant secretes other substances, each having their own beneficial qualities. Biodiversity in green manure helps to improve soil fertility. We use a mix of 11 varieties.
The mix contains corn varieties that root deeply and improve the soil structure, leguminous plants that capture nitrogen from the air and give it off through the roots later, and different crucifers that keep away harmful nematodes.
A healthy, vital soil has a great resistance, and is less susceptible to diseases.
