Rock phosphates are less soluble and agronomically not as efficient the acidulated. However, some rhizobacteria can improve solubilization of inorganic in soil, raising efficiency rock phosphates. The objective was to evaluate development maize plants response application P sources associated with inoculation. A greenhouse experiment carried out six sources: no application; ​​Triple Superphosph...

A pilot-scale field demonstration was conducted at a Pb-contaminated site to assess the effectiveness of Pb immobilization using P amendments. The test site was contaminated by past battery recycling activities, with average soil Pb concentration of 1.16%. Phosphate amendments were applied at a 4.0 molar ratio of P/Pb with three treatments: T1, 100% P from H(3)PO(4); T2, 50% from H(3)PO(4)+50% ...

Improving solubility of rock phosphate is critical for phosphorus (P) management in cropping. This experiment was conducted during 2010 to determine the P solubilized from rock phosphate (RP) through composting with fresh poultry litter (PL). The RP used in the experiment was collected from Hazara area of Khyber Pakhtunkhwa (KP) province, Pakistan. The treatments comprised of PL alone, PL+RP, a...

A greenhouse pot experiment was conducted to evaluate the effect of phosphorous (P) fertilizers application to an alkaline calcareous soil on the water use efficiency (WUE) of lettuce cultivar "robinson" of iceberg type. Head fresh and dry weights, total water applied and WUE were affected significantly by the P fertilizer type and rate. P fertilizers addition induced a significant enhancement ...

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 ...

The Pampa’s rangeland in South America is underused or replaced by annual crops forest cultivation with higher economic returns. Our goal was to test the long term effects of phosphorus fertilizer and limestone applications on P availability, aluminum neutralization deep soil layer productivity. For this, three rates sources combined were applied a 21 year field trial. dry matter (between 2016 ...

This experiment was lay out in order to evaluate the effects of different biofertilizers on seed yield, protein and oil of rapeseed in Iran. The experiment was a factorial design with three replications. Treatments were four nitrogen biofrtilizers (control (N1), Nitroksin (N2), Azotobacter (N3) and Supernitroplat (N4)) and three phosphate biofrtilizer...

in order to determine the effects of applied phosphate bio-fertilizer on yield and morphological traits of wheat, a research was conducted in sari agricultural sciences and natural resources university during 2008-2010. a factorial experiment was performed based on randomized complete block design with four replications. the first factor consists of two levels of phosphate bio-fertilizer (0 and...
