Municipal solid waste and NPK fertilizer effects on soil physical properties and maize performance in Nsukka, Southeast Nigeria

Abstract

A study was carried out in the experimental farm of the Department of Crop Science, University of Nigeria, Nsukka to determine the effect of composted Municipal Solid Waste (MSW) on some soil physical properties and also the effect of combined application of MSW and NPK 20:10:10 fertilizer on maize. Four rates of MSW; 0, 1000, 1500 and 2000 kg/ha and four rates of NPK fertilizer; 0, 100, 200 and 300 kg/ha were tested. These were laid out in a 4 × 4 factorial experiment in randomized complete block design (RCBD). The result shows that the application of MSW did not cause significant improvement in some soil physical properties such as soil aggregate stability, saturated hydraulic conductivity, bulk density and porosity. Maize yield was significantly increased by the application of MSW. Combined application of MSW and NPK fertilizer resulted to higher yield in maize than sole application of either MSW or NPK fertilizer. The highest grain yield was realized from the combined application of 2000 kg/ha of MSW and 300 kg/ha of NPK fertilizer. The result shows that combined application of MSW with NPK performed better than sole application of either MSW or NPK fertilizer. Combination of 2000 and 300 kg/ha performed better than other treatment combinations and was found satisfactory to improve maize performance in sandy loam ultisol in Nsukka.

The effect of municipal sewage sludge on the quality of soil and crops

“…Therefore, studies are needed for land application of sewage sludge to avoid any serious risk to the environment. Municipal sewage sludge fertilizers can improve the physiochemical properties of soil and affect crop yields and its growth (Antonkiewicz and Pelka 2014;Onwudiwe et al 2014;Baawain et al 2014a, b;Jaffar Abdul Khaliq et al 2017). These fertilizers are very rich in macro and micronutrients, which can supply nutrients to plants and increase their fertility (Al-Busaidi 2014b; Zhao et al 2012).…”

Effect of Inorganic Fertilizer on Soil Properties, Growth and Yield of Maize in Makurdi, Southern Guinea Savanna Zone of Nigeria

“…The physical and chemical properties of a soil are one of the fundamental factors affecting maize crop growth and yield. This is because these properties have high degree of correlation with maize crop production and have high influence on soil fertility [10,11].…”

Effect of Vermicomposting and Composting of Municipal Solid Waste (MSW) on Growth, Yield and Quality of Chickpea

“…MSW vermicomposting and composting is being encouraged in many countries of the world and researchers have experienced the benefits of rising MSW in the field. Onwudiwe et al [6] and Elayarajan et al [7] reported that maximum nutrient, yield and quality of maize were observed through integrated application of 100% NPK along with MSW vermicompost and FYM.…”
