One of the main obstacles to plant growth is the lack of the availability of nutrient elements in
many agricultural environments in the world, especially the tropics where soils can be …

Publisher Summary This chapter elaborates the microbially mediated increases in plant-
available phosphorus (P). The importance of microorganisms in soil nutrient cycling and …

The use of phosphate solubilizing bacteria as inoculants simultaneously increases P uptake
by the plant and crop yield. Strains from the genera Pseudomonas, Bacillus and Rhizobium …

Phosphorus (P) is one of the major plant growth-limiting nutrients although it is abundant in
soils in both inorganic and organic forms. Phosphate solubilizing micro-organisms (PSMs) …

The ability of phosphate-solubilizing rhizobacteria to enhance the growth and phosphorus
uptake of canola (Brassica napus L., cv. Legend) was studied in potted soil experiments in …

The global necessity to increase agricultural production from a steadily decreasing and
degrading land resource base has placed considerable strain on the fragile agro …

Two phosphate-and potassium-solubilizing strains (KNP413 and KNP414) were isolated
from the soil of Tianmu Mountain, Zhejiang Province (China) and they were phenotypically …

To fulfil the demand of a growing population for rice food, a better understanding of soil
biological systems is urgently required to improve the efficient use of chemical fertilisers …

Piper nigrum is an interesting plant to study the endophytic microbial factors affecting plant
growth because of its unique features. Endophytic bacterial isolation from the plant resulted …

Biological nitrogen fixation (BNF) is carried out by representatives of various bacterial
phylogeneticgroups named diazotrophs. These bacteria can live free in many ecosystems …
