This study assessed the effect of gas flaring on the physicochemical properties and heavy metal contents in soils of Ebocha gas flaring site in Rivers State. It involved the assessment of various distances from gas flaring point to 200 meters away (50 m, 100 m, 150 m, and 200 m) which represents the extent of gas flared pollution on soils to determine the physicochemical properties and heavy metal load. The gas flaring significantly decreased soil organic carbon and calcium content when compared with non-gas flaring polluted soils. Soil acidity increased, soil exchangeable ions decreased. N, P and K were altered in gas flared soils when compared to the controls. There were detrimental effects on soils physicochemical properties. Heavy metals observed were Cd (Cadmium), Ni (Nickel), As (Arsenic), Cr (Chromium), while Pb (Lead) was not detected. The concentration of heavy metals in gas flared soils decreases down soil depth from 0-15 cm to 45-60 cm respectively. The gas flaring extremely caused the acidic nature of gas flared soils. Coefficient of variation (CV) in percentage shows significant increase in acidic nature of the gas flared soils when compared with the control soils.</p> O. I. Achieche, O. O. Njoku, C. M. Duru, M.

There were five systematically combined rates of vermicompost and one rate of NPS treatments during the study. The experimental design was randomized complete block with three replications. Surface soil samples were collected before planting to analyze selected soil properties. The textural class of the soil was clay. The pH of the soil was rated under moderately acidic. Available P was rated under medium in most of the experimental sites while total N was low in all experimental sites.&nbsp; The treatments significantly affected crop phenology, yield and yield components of wheat. Thus tallest plant height was found from treatments that received 100kg/ha NPS, followed by 8.75t/ha vermicompost which resulted in (73.25cm) while the shortest plant (62.73cm) was obtained from control plots, respectively. Highest mean wheat grain yield (2642.8kg/ha) was obtained in response to 100kg NPS from inorganic fertilizer application followed by the second highest dose of vermicompost (7t/ha) with grain yield of 2620 kg/ha.&nbsp; At the wheat plants grown in plot received vermicompost compost at 7t/ha of vermicompost increased the grain yield by 67.78% over the control. Though highest grain yield was obtained from highest dose of vermicompost the partial budget analysis shows that the highest marginal rate of return (456) was obtained from 3.5t/ha VC ha<sup>-1</sup> plus 100kg/ha urea at the study area.</p> Weldegebriel Gebrehiwot, Tewolde Berhe, Tsadik Tadele, Kinfe Tekulu, Geberesemaeti Kahsu, Solomon Mebrahtom, Samrawit Mebrahtu, Goitom Aregawi, Gidena Tasew, Aklil Gebremedhin ##submission.copyrightStatement## https://journalasrj.com/index.php/ASRJ/article/view/30089 Mon, 26 Oct 2020 00:00:00 +0000 Effect of Losing Nitrogen Fertilizers on Living Organism and Ecosystem, and Prevention Approaches of their Harmful Effect https://journalasrj.com/index.php/ASRJ/article/view/30088 <p>The world’s population is drastically increasing; therefore, an enormous amount of nitrogen and other fertilizers are used to produce enough food for their feeding. Furthermore, since the applied nitrogen amount is not completely absorbed by plants, its big proportion is released to the environment in different ways. The released nitrogen amount damages both humans’ health and the environment. Some technical and agronomical techniques help to minimize the loss of this nitrogen. The fertilizer's loss not only affects farmers' economic condition, but their effects are integrated. Nitrogen fertilizers pollute water, soil, air, as well as our foods. Leaching nitrate can cause eutrophication in sea, lakes, and water bodies. This condition poses a big threat to the lives of fish and other aquatic organisms. It also causes various diseases in humans such as blue baby syndrome, carcinoma, and others. For instance, Nitrate-N (NO<sub>3</sub>-N) leads to the blue baby syndrome, carcinoma, and other diseases in humans. NO<sub>3</sub>-N leaching stimulates the growth of blue-green algae and creates hypoxic zones in the water. Moreover, cyanobacteria produce toxins that affect the liver`, kidney, brain, skin, and other parts of the human body, as well as cause complicated diseases. Ammonia and nitrogen oxides contribute to acid rains and have adverse effects on ecosystems. Nitrous oxides (N₂O) deplete the ozone layer, a layer that prevents harmful rays from reaching the earth. N₂O contributes extremely to global warming due to its potentiality. Although Nitrogen fertilizers have contributed to produce high yields in the world, their excessive application has created different problems in our environment. To reduce nitrogen leaching, some agronomical, technical, and other practices are required to be used in the large and small farming system.</p> Rahmatullah Hashimi, Mohammad Hanif Hashimi ##submission.copyrightStatement## https://journalasrj.com/index.php/ASRJ/article/view/30088 Tue, 15 Sep 2020 00:00:00 +0000
