NPK + Mycorrhiza

Azotobacter in NPK liquid formulation increase nitrogen uptake, produce plant growth hormones (IAA, GA), vitamins enhancement in uptake NO3, NH4, H2PO4, K and Fe. Azospirillum is an associative micro aerophillic nitrogen fixer. This bacterium induce the plant foods to secrete and mucilase which aerate low oxygen environment and helps to fix atmospheric nitrogen. PSB possess the activity to solubilize the Phosphorous by secreting organic acids (Gluconic acid, formic acid, glutomic acid, lactic acid, citrate, malic acid) lower soil pH and turns unavailable forms of soil phosphate to available form. Some of hydroxyl acids ch-e-late Ca, Al, Fe and Mg resulting in effective availability of soil and reduced phosphate dose by 50%. KMB to mobilize potash available in soil of the plant activates the numerous enzymes system involved in formation of organic substances and protein compounds.

Mycorrhizae are obligate and saprophytic in nature requires a living host for their survival. Commonly divided into three major groups Ectomycorrhiza, Endomycorrhiza and Ectendomycorrhiza. Ectomycorrhiza and Endomycorrhiza are important in agriculture, fungi penetrate into the plant cells, producing balloon like vesicles. The structure of the arbuscules increase the contact surface between the hyphal and the cell cytoplasm to facilitate the transfer of nutrients between them and VAM fungi produce the glycoprotein glomalin which may be one of the major stores of carbon in the soil, management of VAM fungi enhances phosphate uptake and mobilize immobile micronutrients like Fe, Mn, Zn, Cu, Bo, Mo. Besides these to impart resistance to plant against drought, soil borne fungal pathogens and nematodes. There is no septum in their hyphae. The fungi hyphae penetrate in to cortex layer of the root and form the hyphal organ “vesicles” and “arbusculus”. The interaction between AM fungi and plants is generally mutualism based upon nutrient exchange.
