This paper presents soil quality as affected by dumped municipal solid waste. Landfill leachate was collected from a hole dug 10 m away from the waste dump site for laboratory analysis. Soil samples were also collected from four trial pits in the dumpsites at the depth of 0.3, 0.6 and 0.9 m and at a distance of 10, 20, 30 m and the control 100 m away from the dumping site. The collected soil samples were subjected to physiochemical and geotechnical analysis. This includes particle size distribution, pH, EC, total organic carbon, total organic matter, extractable micronutrients and heavy metals (Zn, Cu, Mn, Fe, Pb, Cd, Cr, Cl and Ni), Attterberg limits, specific gravity and hydraulic conductivity. The physicochemical concentration was then compared with the maximum allowable concentrations of chemical constituents in uncontaminated soil. The Laboratory analysis shows high value of pH (8.51) DO (0.17 mg/l), COD (68mg/l), BOD5 (324 mg/l), Pb (0.31 mg/l) and Cd (0.06 mg/l) in the leachate sample. The physical properties of the soil near the dumpsite indicated that the soil belongs to sandy loam in texture. pH (6.3-8.32), Electrical conductivity (241-2018 s/cm), total organic carbon (0.24-2.16 ) and total organic matter (0.41-3.73%) were higher near the vicinity of the dumpsite and decreased with increase in the depth and distance. Extractable micro nutrient and heavy metal concentration (Zn, Cu, Mn, Fe, Pb, Cd, Cr, Cl and Ni) were also found to be high near the dumpsite and decreased along the soil depth and distance from the dumping site. The variance in the geotechnical properties of soil revealed by the test results was impacted by the dumped municipal solid waste. These effects decrease with increase in depth. These findings will help in facilitating the invention and introduction of site specific technologies.

The preliminary study was carried out to evaluate the growth performance of Jatropha curcas seedlings on different soils at the nursery of the Federal College of Forestry Mechanization Afaka, Kaduna. Farm land soil, forest soil and granulated iron stone soil were sourced within the college premises and FRIN/JICA plantation. Jatropha curcas seedlings were sown on the different soils and each was replicated eight (8) times. The experiment was laid out in Complete Randomized Design (CRD). Growth parameters were collected forth nightly and was subjected to Analysis of Variance (ANOVA) and Duncan Multiple Range Test (DMRT). Results revealed that there are significant (P>0.05) difference in the height, stem diameter and number of leaf among the three different soil for the growth assessment. The growth rate recorded from the farm land soil are statistical higher (P>0.05) in leaf width, plant height and stem diameter than the other two soil while the growth parameters assessed were significantly lower (P>0.05) in iron stone soil and forest soil. It is recommended based on the parameters assessed that soil from the farmland gives the best result for raising and nurturing of J. curcas in the nursery without addition of any plant nutrient media.

In Malawi, inoculating soybean with rhizobia, has been advocated for decades as a way of boosting productivity through enhancement of biological nitrogen fixation. The effectiveness of this strategy however, has been constrained by the low soil fertility status of soils in Malawi, necessitating the use of mineral fertilizer to supply nutrients to the soybean for increased productivity. Alternative strategies like foliar feeding of nutrients to improve grain yields are yet to be widely promoted due to lack of research evidence. Therefore experiments involving the soybean were conducted during the 2016/17 cropping season, laid in a randomized complete block design (RCBD) replicated four times, at Bvumbwe, Bembeke and Chitala  in Malawi to evaluate yields response to foliar feeding using a foliar fertilizer (Allwin-legumes). Agronomic data were analyzed in Genstat Discovery Edition 4 and were subjected to analysis of variance at 95% level of confidence. Means were separated using the least significant difference (LSD0.05). Generally, the result indicate that foliar feeding produced significantly higher (p<0.05) grain yields ranging from 33.7-364.7%, above the control across the different agro-ecological zones. The result underscores the importance of judicious and methodical application of nutrients to soybean under the changing climate and conditions of low soil fertility. In general, foliar feeding using Allwin fertilizer particularly when conducted twice can increase significantly soybean productivity in Malawi. The grain yields increase is attributable to the enhanced crop growth and development through foliar supply of nutrients.

A field experiment was carried out at Sher-e-Bangla Agricultural University Farm during the Rabi season of November 2008 to March 2009 to investigate effect of different levels of potassium fertilizer on the yield components of BARI Bush Bean-2. The red brown terrace soil of Tejgaon was silty clay loam having pH 5.6. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The experiment comprises 4 levels of potassium in the form of MoP (0, 20, 40 and 60 kg potassium/ha). The results revealed that different levels of potassium showed significant variations on the yield and yield components of BARI Bush Bean-2. The treatment K40 (40 kg potassium) gave the maximum pod length (10.90 cm), pod diameter (2.95 cm), average single pod weight (5.49 g), total pod weight per plant (25.37 g), pod yield per plot (1795.83 g) and pod yield per hectare (4.38 ton). Thus the results of the experiment suggested that the use of 40 kg potassium produced highest yield of BARI Bush Bean-2 in red brown terrace soil of the Tejgaon series.

To assess the quality of River Onyongo catchment area for agricultural purposes. Field and laboratory assessment was carried out.

Water resources potential assessment was carried out in part of River Onyongo catchments area. The topographical map was used to carve out the study area. Geological mapping of the study was carried out by compass. Field permeameter pits were established in four locations within the study area to determine the coefficient of permeability of sub-surface soils/lithology by Darcy Law. Depth to water table was measured in some selected hand-dug wells. Discharge measurement of River Onyongo rainy season was 199,888.12 litres/second and 2,770.62 litres/second in dry seasons while River Ichow (bridge) had 354.3 litres/second in the rainy season and 195.43 litres/second at the upstream; there was no flow during the dry season. Water samples were collected in the various locations in the study area and analysed in the laboratory. The relief of the study ranges from 100 m to 223 m above mean sea level. The Sodium Absorption Ratio (SAR) of the water sample ranged from 0 – 10 mg/l indicating that water can be used on all crops and all soils. The coefficient permeability/lithology of the study area ranged from 0.36 – 29.5 m/day corresponding to fine-grained sand to medium-grained sand – coarse-grained sand. Recommendations for the use of water for optimal agricultural purposes and production in the study areas were made.
