In large areas of sub-Saharan Africa crop production must cope with low soil fertility. To increase fertility, the application biochar (charred biomass) has been suggested. urban areas, untreated waste water is widely used for irrigation because it a nutrient-rich year-round source. Uncertainty exists regarding interactions between properties, biochar, and fertilization over time. The aims this study were to determine these in two typical sandy, organic carbon (SOC) nutrient depleted soils...
ABSTRACT Background Carbonized organic matter (biochar) and compost are both beneficial soil amendments particularly meaningful for the restoration of degraded soils. Application biochar adds stable carbon (C) but only little nitrogen (N) to soil. Compost is rich in C N, losses these elements during composting large, stability relatively low. The addition has been reported decrease N losses, accelerate process, increase cation exchange capacity (CEC), water‐holding compared without biochar....
Abstract This study reports and analyzes nutrient balances in experimental vegetable production systems of the two West African cities Tamale (Ghana) Ouagadougou (Burkina Faso) over a two‐year period comprising thirteen eleven crops, respectively. Nutrient‐use efficiency was also calculated. In Ouagadougou, up to 2% (8 80 kg N ha −1 ) annually applied fertilizer nitrogen were leached. While biochar application or wastewater irrigation on fertilized plots did not influence leaching both...
Abstract To quantify carbon (C) and nitrogen (N) losses in soils of West African urban peri‐urban agriculture (UPA) we measured fluxes CO 2 ‐C, N O‐N, NH 3 ‐N from irrigated fields Ouagadougou, Burkina Faso, Tamale, Ghana, under different fertilization (waste‐)water regimes. Compared with the unamended control, application fertilizers increased average cumulative ‐C emissions during eight cropping cycles Ouagadougou by 103% seven Tamale 42%. Calculated total across all reached 14 t C ha −1...
This study investigated the effects of corn cob biochar (CCB) and rice husk (RHB) additions (at 0%, 5%, 10% w/w) on nitrogen carbon dynamics during co-composting with poultry litter, straw, domestic bio-waste. The further assessed temperature, moisture, pH, nutrient contents mature co-composts, their potential phytotoxicity amaranth, cucumber, cowpea, tomato. Biochar decreased NH
Abstract Adding biochar to nutrient rich organic matter during composting reportedly reduces nitrogen (N) volatilization and carbonization of feedstock stabilized carbon (C). We studied the effects biochar, produced from agricultural residue as compost additives, on CO 2 , N O, NH 3 fluxes in northern Ghana. Three types [from corn cobs (cCC), rice husks (cRH), wood (cWO)] their uncharred feedstocks (CC, RH, WO), were co‐composted with poultry manure (15 vol.‐%) straw (60 randomly allocated 1...
Abstract Background Little is known about the effects of gypsum application to remediate saline–sodic soils in tropics and role microbial indicators soil reclamation. Aims Our study aimed at (1) remediating a highly weathered, irrigated sodic Lixisol under prolonged urban crop production by clean water (2) determine remediation on indices. Methods A three‐factorial on‐farm experiment with maize ( Zea mays L.) was used biomass degradation two levels salinity, irrigation wastewater, (3) impact...
The editorial office would like to draw reader's attention an error occurring in the publication by Akoto-Danso et al. · Nutrient flows and balances intensively managed vegetable production of two West African cities pp. 229–243 Volume 182 Number 2 April 2019 that we apologize for. 1. Abstract, 3rd sentence: correct sentence is: "While biochar application or wastewater irrigation on fertilized plots did not influence N leaching, P K as determined with ion-absorbing resin cartridges, were...
