Embodiment Construction

[0024] In one embodiment, the present invention provides a biological fertilizer composition comprising yeast cells. The present invention also provides, in various embodiments, methods of making biological fertilizer compositions and uses of biological fertilizer compositions.

[0025]The biological fertilizer composition of the present invention can replace chemical / inorganic fertilizers to supply nitrogen (N), phosphorus (P) and potassium (K) to plants, especially crops. The biological fertilizer composition of the invention can increase crop yield by 10-60%. Since the bio-fertilizer of the present invention uses the metabolic activity of live yeast to convert raw materials such as atmospheric nitrogen, phosphorus and potassium inorganic substances into plant nutrients, the conversion and release of these nutrients by yeast cells is partially regulated by the nutrient content in the soil. The nutrient content of the soil, in turn, depends in part on the environment and the...

Abstract

The present invention provides biofertilizer compositions comprising yeast cells with enhanced fixation of atmospheric nitrogen, decomposition of inorganic phosphorus and its compounds, decomposition of inorganic potassium and its compounds, decomposition of complex carbon compounds, overproduction of growth factors and excess Ability to produce ATP. The biological fertilizer composition of the invention can replace inorganic fertilizers to provide nitrogen, phosphorus and potassium to crops. The invention also includes a production method and an application method of the biological fertilizer composition.

Description

1. Field of invention [0001] The present invention relates to a biofertilizer comprising yeast for the fixation of atmospheric nitrogen and for the decomposition of insoluble compounds containing phosphorus, potassium and / or carbon. The invention also relates to a method for preparing biological fertilizer and a method for improving crop yield with biological fertilizer. 2. Background of the invention [0002] Fertilizers are necessary to support the growth of high-yielding crops. Among the basic nutrients required for the healthy growth of plants, a large amount of nitrogen (as NO 3 - or NH 4 + uptake), phosphorus (as H 2 PO 4 - intake) and potassium (as K + Uptake) Nutrients are required by most crops growing on most soils (Wichmann. W. et al., IFA World Fevtilizer Use Manual). Such a large amount of nitrogen, phosphorus and potassium nutrients are mainly provided in the form of mineral fertilizers, which can be processed natural inorganic substances or manufactur...
