The aim of this study was to evaluate P availability, P and C contained in the microbial biomass, and enzymatic activity (acid phosphatases and β-glucosidases) in a Nitisol with the application of mineral and organo-mineral fertilizers. The experiment was performed in a protected environment with control over air temperature and soil moisture. The experimental design was organized in a "5 x 4" ...

This work aims to valorize an invasive brown macroalga (Sargassum spp. consisting of two species Sargassum fluitans and natans) by producing biochars (BCs) activated carbons (ACs). Its abundant frequent occurrence along the Caribbean coastlines, Florida, Gulf Mexico during last past nine years, have triggered human health concerns negatively impacted local economy, ecology environment. In this ...

The field experiment was conducted in 2018 and 2019 cropping season to determine the effects of urea stable on nitrogen use efficiency maize performance highland Nitisol Midakegn Toke Kutaye districts. laid out randomized complete block design with three replications. Nine treatments different application times used. Application rate from were significantly (P < 0.05) influenced mean plant h...

The productivity of the faba bean has declined in Ethiopia, owing to poor management practices, such as blanket fertilisation. In 2018, a field experiment was conducted Nitisol soil during main cropping season Northwestern determine amount chemical fertiliser and Rhizobium inoculant be used for optimum yield within economic feasibility. consisted factorial combination five rates blended NPSZnB ...

Sugarcane cultivation is suitable for the exploitation of organic waste products. However, minimum complementary mineral input necessary optimal fertilisation. Control fertilisation treatments with mulch (MCM) or without (MC) were compared two treatments, a pig slurry (PSM) and (PS), sugarcane vinasse (SVM) (SV) on Nitisol in French Reunion Island. The yields obtained different differed each ye...

Abstract Changes in soil organic carbon (SOC) and aggregate stability as a result of agricultural practices have been extensively studied, but the extent these changes is site crop specific. In this study, SOC were evaluated under undisturbed grassland, cultivated pasture arable land uses northern KwaZulu-Natal, South Africa. The soils study sampled from 0–5, 5–10 10–20 cm depths Nitisol, Stagn...

Detailed knowledge of chemical, petrographic and mineralogical compositions as well the effects applying rock powder on soil chemical properties plant production are required for classifying these materials remineralizers (SR), according to Brazilian legislation in force. This study aimed evaluate potential powders siltstone, tephrite olivine melilitite, pure or mixed, improving fertility a Cam...

Sweet potato [Ipomoea batatas (L) Lam] yields currently stand at 4.5 t ha-1 on smallholder farms in Uganda, despite the attainable yield (45-48 t ha-1) of NASPOT 11 cultivar comparable to the potential yield (45 t ha-1) in sub-Saharan Africa (SSA). On-farm field experiments were conducted for two seasons in the Mt Elgon High Farmlands and Lake Victoria Crescent agro-ecological zones in Uganda t...
