Dextrose is a sugar derived from corn and research suggests that it is very valuable when mixed with liquid nitrogen. Dextrose has a very valuable role to play in supplying the sugars that feed the bacteria as the bacteria are just beginning to break dormancy and get active in the soil.
Vesicular Arbuscular Mycorrhizal (VAM) is a fungus which has the ability to dissolve the phosphates found in abundance in the soil. Apart from increasing the availability of phosphorus, VAM provides the plants with the necessary strength to resist disease germs and unfavourable weather conditions and to tolerate various pathogenic infections.
VAM fungi can increase the nutrient uptake of their host plants. Arbuscular mycorrhizal association with the host plant increases the uptake of water and most essential mineral nutrients for their host plant, such as phosphate and nitrogen.
