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...

Phosphorus (P) is one of the most important elements required for crop production. The ideal soil pH its absorption by plants about 6.5, but in alkaline and acidic soils, consumed P forms an insoluble complex with calcium, iron, aluminum availability plant decreases. supply needed mainly achieved through chemical fertilizers; however, addition to high price these fertilizers, long run, their de...

Phosphobacteria is one among the soil microorganisms which plays an important role in improving the chemical and physical nature of the soil, adding organic matter to soil, solubilizing the insoluble phosphate increasing availability and utilization of growth and yield. The phosphate solubilizing bacteria, which were inoculated with Avicennia officinalis seedlings, increased significantly the a...

One of the main limitations in intensive crop production in Northwestern Mexico is the dependence on the use of phosphate fertilizer. In this study, we isolated indigenous microorganisms with phosphate solubilization capacities from mesquite (Prosopis glandulosa) present in the Mexicali valley. In total, 4 bacteria were isolated from the rhizosphere of mesquite, including ICA01, ICA02Ba, ICA03B...

to evaluate the effects of some phosphorus solubilizing bacteria strains on yield and agronomic traits in local bean (phaseolus vulgaris l.) of guilan, different phosphate fertilizer rates were tested during 2014 growing season. this research was carried out in experimental field of agricultural and natural resource research center of guilan province as split plot arrangement based on randomize...

Winter oilseed rape was cultivated in monoculture or in combination with turnip rape as trap crop sown in trap strip. Preventative microbiological treatments for diseases control in winter oilseed rape were tested using Trichoderma asperellum and product based on effective microorganisms. Microorganisms were effective to protect of oilseed rape and allowed to obtain higher yield comparing to un...

Phosphorus is the second most important macro nutrient required by the plants for its optimum growth and yield. But it is considered to be a most limiting factor of many crop production systems, due to its unavailability of soluble forms in the soils. About 80% of applied P fertilizers are immobilized due to the formation of complex with Al or Fe in acidic soils or Ca in calcareous soils. An al...

the high cost of fertilizers in farming systems, soil pollution and degradation of soil are factors that caused to full use of available renewable nutrient sources of plant (organic and biological) with optimal application of fertilizers in order to maintain fertility, structure, biological activity, exchange capacity and water-holding capacity of the water in soil. therefore, in recent years, ...
