Adding mycorrhizal fungi into difficult soils will enable plants to establish and thrive. In poor sandy soils the mycorrhizal fungi will be able to find scarce nutrients and hold onto water. In clay soils these fungi will be able to release nutrients from the soil acting like a clay breaker. The benefits to plants are;
Better nutrient uptake. These fungi are so much finer and thinner than the plant’s own roots, they can therefore find nutrients in the soil far more efficiently than the plant’s own coarse roots.
They are especially good at finding nutrients responsible for flowering and fruiting such as Phosphorus and Potassium. As they can explore a much greater amount of soil than the plant’s own roots they are also far more likely to find trace elements and the rare nutrients that all plants need to grow well.
