A pot experiment was carried out to study the phosphrous-sulphur interaction at Department of Agricultural Chemistry and Soil Science, Rajasthan College of Agriculture, Udaipur on a sandy loam soil (Typic Haplustept) medium in P and deficient in S with clusterbean. The treatment consisted of three levels of P (0, 20 and 40 kg P O ha ) and three levels of S (0, 10 and 20 kg ha ) applied from gyp...

A biotechnological strategy for the production of an alternative P fertilizer is described in this work. The fertilizer was produced through rock phosphate (RP) solubilization by Aspergillus niger in a solid-state fermentation (SSF) with sugarcane bagasse as substrate. SSF conditions were optimized by the surface response methodology after an initial screening of factors with significant effect...

BACKGROUND Pyrolysis of slaughterhouse waste could promote more sustainable phosphorus (P) usage through the development of alternative P fertilizers. This study investigated how pyrolysis temperature (220, 350, 550 and 750 °C), rendering before pyrolysis, and wood or corn biomass additions affect P chemistry in bone char, plant availability, and its potential as P fertilizer. RESULTS Linear ...

In acid soils, soluble inorganic phosphorus is fixed by aluminium and iron. To overcome this problem, acid soils are limed to fix aluminium and iron but this practice is not economical. The practice is also not environmentally friendly. This study was conducted to improve phosphorus availability using organic amendments (biochar and compost produced from chicken litter and pineapple leaves, res...

Agricultural intensification is associated with the use of great amounts of agrochemicals that may result in the accumulation of metals in soils, and –subsequently—agricultural products and food chain. Nowadays, this is a major concern for many Iranian agricultural products, necessitating scientific researches on the issue. Therefore, the present study has been conducted to evaluate the level o...

introduction bean (vicia faba l.) has the great old history of crop cultivation to date would be pushed back to a fairly long day plant, resistant to frost and cool season crop and up to 5 degrees celsius tolerated. bean prefers wet and cold conditions. excessive heat may cause fetal growth problems, loss and reduce the number of seeds per pod bean flowers to the growth of plant and fruit set o...

The concern about soil quality has increased, since its use and intense mobilization may decreased its ability to keep a biological and sustainable production. However, since soil quality cannot be comprehensively measured by a single indicator, emergy synthesis rises as an alternative to assess this issue. This study aimed to present a comparative method for soil quality vis-a-vis the resource...

Low phytic acid (LPA) barley (Hordeum vulgare L.) cultivars partition phosphorus (P) in seed tissue differently than conventional wild-type (WT) barley cultivars. A reduction in seed phytic acid (myoinositol-1,2,3,4,5,6-hexkisphosphate) is coupled with an increase in inorganic phosphorus (Pi). The response of the LPA characteristic to phosphate fertilization has not been previously investigated...
