Introduction Research at CLIMA has indicated that Lathyrus cicera and L. sativus (grasspea) have potential as grain legumes on 100 000 to 300 000 ha of neutral to alkaline soils in low-to-medium rainfall areas of southern Australia. They do not have serious disease problems and are envisaged as low maintenance/low cost crops for the purposes of green manure, managing herbicide resistant weeds, ...

Knowledge of spatial variability in soil fertility is important for site specific nutrient management. In this study, spatial variability in properties that influence soil fertility such as soil organic carbon (OC), available N, available P O and available K O in surface soils of 154 farmers' fields of Karlawad village in 2 5 2 Navalgund taluk of Dharwad district of Karnataka (India) were quant...

Organo-arsenical compounds are considered non-carcinogenic, and hence, are still allowed by the regulatory agencies for use in agriculture as pesticides. Due to rapid encroachment of suburban areas into former agricultural lands, the potential for human exposure to soil-arsenic has increased tremendously in recent years. However, insufficient data is available on the stability of organo-arsenic...

Humic acids are complex, partly macromolecular, yellow-brownish substances occurring in soils, waters and sediments. In order to bring some light on their molecular structure, crop humic acids were cleaved by alkaline hydrolysis (KOH). The products were fractionated by thin layer chromatography to give mono-alcohols which were analysed as acetate derivatives by gas chromatography coupled to mas...

Recent studies have shown that nitrification inhibitor (NI) impairs the efficacy of urease inhibitor, N-(n-butyl) thiophosphoric triamide (NBPT), in reducing ammonia volatilization and urea hydrolysis rate. A laboratory study was conducted to evaluate influence NI (specifically 3,4-dimethyl pyrazole phosphate) on degradation NBPT six soils. Soils were amended with either (10 mg kg−1 soil) or pl...

The effective and safe use of FGD gypsum in agricultural land is still debated some countries even though its effectiveness soil management has been reported many studies. Thus, the changes levels salinity, alkalinity, crop yield, other physicochemical properties different types crops after reclamation planting with over four years are evaluated this paper. main aim paper to review effects six ...
