Purpose Rapid nutrient depletion in soils is one of the major problems that affect food production and food security in Sub-Saharan Africa. Studies have linked the growth of food crops with seasonal variation and differences in weather conditions. This study was conducted to assess the effects of various organic fertilizer formulations (OFFs) on the growth […]
Purpose Biochar application could be a sustainable way to enhance the nitrogen fixation in Bambara groundnut and other legumes. The research was conducted to study the effect of rice husk biochar and the Christmas Island Rock Phosphate application on the performance of Bambara groundnut in the study area. Method Two levels of rice husk biochar […]
Purpose The beneficial effects of liquid humus applied to plants are well reported in the literature; however, studies of liquid humic application in the production and quality of garlic culture are practically nonexistent. The objective of this work was to evaluate the effects of foliar application of a liquid humic extract from vermicompost (HEVC) that […]
Purpose Persistence of herbicides in soil is a major concerning world issue due to their negative impacts on environment and human health. Laboratory and bioassay experiments were conducted to evaluate the effects of municipal waste compost (MC) and sheep manure (SM) on metribuzin degradation and phytotoxicity of this herbicide. Method In degradation studies, soil samples […]
Purpose The nursery is the production of vigorous seedlings for field transplantation. Fertilization improves the quality of Moringa oleifera in the greenhouse. Thus, the effect of composts amendments on the survival rate and mineral composition of M. oleifera was studied. Method A randomized complete block (RCB) design comprising fourteen treatments and twelve repetitions (pots referring […]
Purpose Climate change and global food demand in coming decades urge effective actions for more efficient uses of water and soil resources. This paper reports the preliminary findings of a study assessing the potential of sheep scoured wool residues (SWRs) as soil amendments to enhance the physical and hydraulic properties of a sandy loam soil […]
Purpose The aim of this study was to prove that the Fe-containing by-products (compost, sewage and lime sludge) have potential influence on the correction of Fe deficiency in sunflower and maize. Method The physiological parameters used were the dry matter (DM), the relative chlorophyll content, and the content of photosynthesis pigments (chlorophyll a, chlorophyll b […]
Purpose Nitrogen loss as ammonia (NH3) in a waste cocoa pod co-composting process was determined following the addition of three potential chemical amendments that could lower NH3 loss. Further, amended compost products were assessed for quality and possible phytotoxicity in a pot experiment. Method Pod borer damaged cocoa pods were co-composted in lab-scale vessels under […]
Purpose Industries are generating numerous amount and types of organic wastes to the environment. The aim of the present study was to investigate the effects of agro industrial wastes compost on soil physicochemical quality, soil microbial population, growth and yield of onion (Allium cepa L.) under field condition. Method The experiment was conducted in a […]
Purpose Soil fertility management requires a precise assessment of nutrient release from organic amendments to decide the rates and frequency of application. Method Time-dependent release of some macro- and micro-nutrients from farmyard manure, mushroom compost, poultry manure, vermi-compost, biogas slurry and biochar of Lantana sp. was studied during 120 days incubation through entrapment of released nutrients on ion […]
