Understanding carbon mineralization dynamics of organic amendments is essential to restore degraded lands. This study focused on the restoration potentials tea-growing soils using materials available in tea ecosystems. The Selangor-Briah soil series association (Typic Endoaquepts) consisted a high- (soil A) and low-carbon B) were incubated with different released dioxide (CO2) measured. Two kinetic models applied depict process. Soil health parameters including microbial biomass nitrogen,...
Official journal of the Postgraduate Institute Agriculture, University Peradeniya. Tropical Agricultural Research publishes complete accounts research outstanding significance, together with critical review articles on all aspects agriculture including agronomy and crop production, horticulture, agricultural biology, food nutrition, soil water resource management, engineering, economics, animal science, biotechnology, plant protection, genetics breeding.Tropical is now indexed in DOAJ.
Understanding of N mineralization dynamics frequently available organic amendments in the tea (Camellia sinensis (L.) O. Kuntze) ecosystem has greater importance land restoration. Hence, this study focused on assessing effects and soil quality improvement growing soil. Garden compost (CMP), Gliricidia (Gliricidia sepium (Jacq.)) leaves (GLI), charged waste biochar (CBC), (TW), without charging (RBC) were incubated with at a rate 186 mg kg-1. Incubated soils analyzed periodically for pH, NO3...
Phosphorus (P) enrichment of soil due to the intensification P fertilizer usage in crop production has resulted eutrophication and serious economic consequences. Further, rapidly decreasing reserves have renewed interest improving more sustainable management through monitoring diverse reactions contrasting soils. Therefore, study was conducted (i) characterize sorption desorption capacities related properties (ii) determine added availability distribution among different pools over period...
Phytoextraction is an attractive method to extract excess soil phosphorus (P) builds up from the soils. The crops potential enriched P in still lacking. Therefore, four were grown three different soils with variable levels (0 200 mg P/kg soil) and screened for acquisition potentials. Total accumulation roots shoot was high all soils, example A at soil, values 0.44% cucumber (Cucumis sativus), 0.40% sunflower (Helianthus annus), ∼0.30% cabbage (Brassica oleracea) 0.20% Indian mustard juncea)....
The rice plant accumulates silicon (Si) in greater quantity, which varies among the genotypes. This study was conducted to determine optimum fertilization rate and its effect on growth, yield, yield attributes, soil nutrient uptake. Six different dioxide (SiO2) rates, including 0, 50, 75, 100, 125, 150 kg SiO2/ha, were applied initially. of SiO2 obtained by statistical analysis, utilizing analysis variance (ANOVA) Duncan’s Multiple Range Test (DMRT) separate means. results showed that shoot...
