The interactive effect of phosphate-solubilizing bacteria and arbuscular mycorrhizal (AM) fungi on plant use of soil P sources of low bioavailability (endogenous or added as rock phosphate [RP] material) was evaluated by using soil microcosms which integrated (sup32)P isotopic dilution techniques. The microbial inocula consisted of the AM fungus Glomus intraradices and two phosphate-solubilizin...

native phosphate solubilizing bacteria (psb) were isolated from four areas (ankober, keyt, mehalmeda and molale) of ethiopia to study their effect on releases of soluble phosphorus from insoluble p sources. the highest bacterial number was found at keyt (2.6103 g-1soil) and the least at molale (15 g-1soil). five efficient psb were selected for further study based on their ability in forming a ...

phosphorus is an essential element for plants. much of the agricultural lands of iran has calcareous soils, in which, due to high ph, phosphorous availability is less, therefore, it appears as a limiting factor for plant growth. application of biofertilizers instead of chemical ones has gained attention in order to produce healthy crops, reduce pollution of soil and water resources by reducing ...

Strain P17 was a bacterial strain identified as Bacillus megaterium isolated from ground accumulating phosphate rock powder. The fermentation broth of strain P17 and the yellow-brown soil from Nanjing Agricultural University garden were collected to conduct this study. The simulation of fixed insoluble phosphorous forms after applying calcium superphosphate into yellow-brown soil was performed ...

in order to investigate the role of bacillus cogulans on yield of two forage corn cultivars, an experiment carried out at agricultural research center of tehran province during 2009-2010. the experiment design consisted of three randomized complete blocks in a factorial arrangement. investigated treatments consisted of the kind of phosphorus and cultivar. the phosphorus factor included of the a...

biofertilizer is a substance which contains living microorganisms which can use instead of chemical fertilizer in sustainable crop production. the effects of phosphate solubilizing bacteria; root endophytic fungi (ef) piriformospora indica, and arbuscular mycorrhizal fungus (amf) glomus mosseae on growth and nutrient uptake of sunflower plants grown in mixture with two clover species, persian c...

Phosphorus (P) plays a vital role in many aspects of plant growth and development. The low amount available P agricultural soils reduces crop productivity phosphate fertilizers are often applied. However, due to the high affinity for soil constituents, availability this element becomes limited plants. Thus, alternative, ecological, low-cost techniques have been studied improve acquisition by cr...
