Biodegradable solid waste management by microorganism: Challenge and potential for composting

Purpose Composting is known since long for reducing the use of synthetic chemical fertilizers. These fertilizers are applied to the crops for the supply of required macro/micronutrients. The present study describes how to decompose biodegradable solid wastes quickly into compost without harming the environment. Method The microbial inoculums were developed from cow dung concentrate. The […]

Malting barley response to integrated organic and mineral nutrient sources in Nitisol

Purpose Depletion of soil fertility accounts for the low yield and quality of malting barley (Hordeum vulgare) in Ethiopia. Mineral fertilizers can counteract nutrient depletion but are unafordable by low-input farmers. Organic amendments can contribute to correct soil degradation but are often unavailable in the required amounts. Therefore, this experiment was conducted to investigate the […]

Poultry feather waste management and efects on plant growth

Purpose Poultry industries produce a lot of feathers which are considered as waste and needs to be managed properly. Poultry feathers are rich with keratin protein and therefore they could be a source for good nitrogen fertilizer. Proper treatment of poultry feather waste (PFW) might be an environmental friendly solid waste management tool and a […]

The effects of biosolid application on soil chemical properties and Zea mays nutrition

Background: The application of biosolid as a fertilizer in agricultural cultivation is a common practice in many countries. This study investigates the effects of sewage sludge and compost usage on soil chemical properties and Zea mays nutrition in comparison with those of iron and manganese sulfate solution. The experiment was carried out in a completely […]

Compost’ leachate recycling through land treatment and application of natural Zeolite

Background: The entrance of untreated wastewater or disposal leachate to water resources such as surface water, groundwater or irrigation water increases the risk of contaminant accumulation. Removal or deduction of water contaminant concentration is then crucial before entering water to the natural resources or its transfusion directly to the soil as irrigation water. Four studies […]

Bioconversion of organic solid wastes into biofortified compost using a microbial consortium

Purpose Urban municipal solid waste in India are 75–85% organic. Uncontrolled dumping of this waste is a major health concern. Degradation of organic waste by use of a microbial consortium is safe, efficient and economic. Therefore, this study was taken up to recycle the organic solid waste into effective compost using a microbial consortium. Methods […]

Growth and proximate composition of Amaranthus cruentus L. on poor soil amended with compost and arbuscular mycorrhiza fungi

Purpose The study was carried out to examine growth, shoot yield, dry matter and proximate composition of Amaranthus cruentus on poor soil augmented with compost or AMF either singly or in combination. Methods The experiment was arranged in completely randomized designed in six replicates with four treatments. Four treatments: comprised control and three other amendment […]

Organic and inorganic fertilizer application enhances the effect of Bradyrhizobium on nodulation and yield of peanut (Arachis hypogea L.) in nutrient depleted and sandy soils of Ethiopia

Purpose An investigation was carried out to evaluate the effect of the integrated application of organic and inorganic fertilizer effect on Bradyrhizobium effectiveness on nodulation and yield of peanut at the major growing areas of Eastern Ethiopia, Babillae and Fedis sites. Methods Systemic combination of compost, manure, Bradyrhizobium inoculation and NP application was laid out […]

Biochar‑compost mixture as amendment for improvement of polybag‑growing media and oil palm seedlings at main nursery stage

Purpose Production of oil palm seedling in the nursery mainly utilises top soil as polybag medium. These soils, especially in tropical regions, are acidic and have low organic matter content. The aim of this study was to investigate the efects of oil palm empty fruit bunch (EFB) biochar and compost incorporation as amendment in polybag […]

Application of rock phosphate enriched composts increases nodulation, growth and yield of chickpea

Purpose Phosphorus (P) defciency in agricultural land is one of the main factors which reduce the crop production and yield. To increase the crop growth, the availability of P using the rock phosphate (RP) can be enhanced using organic waste with the addition of phosphate solubilizing microorganisms (PSMs). Moreover, the combination along with time and […]
