The pure spores of four different mycorrhiza species form the active ingredient of VA PWI. This composition is supplemented with natural catalysts to ensure a good start of these essential fungi. Endo mycorrhizal fungi are an essential requirement for almost all crops for healthy plant growth. The hyphae of mycorrhiza provide the plant an extended uptake capacity by 700% average. This allows the plants to deal efficiently with water and fertilizers. The fungal threads are able to grow in the fi nest soil pores to get the sparing nutrients for plants. Leaching can be prevented by dosing of fertilizers and use of mycorrhiza.
Hyphae of mycorrhizal fungi support the mobilization of P, N, S and various trace elements such as Cu and Zn to the plant. The mobilization of these elements promotes the nutrient density which is essential in food/feed crops. Research has shown that tolerance to (environmental) stress factors can be increased by the use of mycorrhiza. Plants that grow with mycorrhiza are more resistant to salinity stress for example. Use of mycorrhiza is directly visible in the increased dry matter content, vegetative growth, fruit weight and plant health. The growth of plants under field conditions in combination with mycorrhiza can be increased by 300%.
The use of mycorrhiza is not only important for plants, these fungi are also essential for the soil structure. By enlarging the root system, a more airy soil is created which is better able to buffer water. Glomalin, secreted by these mycorrhizae, also provides for the binding of soil particles and minerals. In addition, glomaline is important in capturing CO2 in the soil, soil structure, preventing erosion and water stability.
