Plant growth promoting rhizobacteria (PGPR) are a group of soil microorganisms which can
enhance plant growth parameters and can be used as biofertilizers. The aim of this chapter …

It is undoubtedly clear that phosphorus is the second most important nutrient after nitrogen
required for growth of plants. It is an essential element in all living systems. Hardly 1%-2% of …

Phosphorus has been identified as one of the most numerous elements that are available in
the earth's crust which exists in the form of both inorganic and organic forms. The presence …

The green revolution bought amazing consequences in food grain production but with
insufficient concern for agriculture and environmental sustainability. The efficient …

Enormous increasing human population and its life forms depend on the sustainable
agriculture, food security and also on the soil characteristics. Due to overpopulation the …

Plant growth promoting rhizobacteria (PGPR) are the living micro-organisms which colonize
the rhizosphere or the interior of the plant or promotes growth by increasing the supply or …

Soil microorganism plays an important role in regulating the levels of carbon, nitrogen,
phosphorus and sulphur at the rhizosphere. Solubilization of macronutrient is an important …

Microbes are vital for agriculture, specifically for soil and plant health. Various mechanisms
such as atmospheric nitrogen fixation, solubilization of mineral nutrients, synthesis of …

Plants absorb many nutrients and elements from soil. These elements are continuously
removed from soil. Therefore, there is a continuous demand for replenishment of these …
