Abstract

The study was conducted at the Abuhoy Gara Catchment, which is located in the Gidan District of North Wello Zone in the ANRS in year 2014. The aim of the study was to study farmers’ perceptions about assessment of soil fertility and comparing them with the criteria of soil fertility used by researchers. To address this issue, semi-structured interviews were conducted in 60 households to gain insight into soil fertility management practices, local methods used to assess the fertility status of a field, and perceived trends in soil fertility. Thirty-three farmers were then asked to identify fertile and infertile fields. Characteristics of these fields in terms of the indicators mentioned in the interviews were recorded, and soil samples were taken for physicochemical analysis in a laboratory. The collected data were grouped according to altitude, slope and type of field. A total of six indicators (soil color, texture, soil depth, topography, soil drainage, and distance from home) were found to be used by farmers to evaluate and monitor soil fertility, which were classified into three categories: Crop production, soil fertility and soil degradation). The overall result showed that there was good agreement between farmers’ assessment of the soil fertility status of a field and a number of these indicators, particularly soil color and texture, which were examined in more detail. The soil physicochemical analysis also corresponded well with farmers’ assessment of soil fertility. The soil attributes under improper cultivated land showed an overall change towards the direction of loss of its fertility compared to the condition of the soils under proper management. The manner in which soils are managed has a major impact on soil fertility indicators. In order to bring sustainable change in soil quality, research activities must follow scientific and participatory approaches. Therefore, to design more appropriate research and to facilitate clear communication with farmers, researchers need to recognize farmers’ knowledge, perceptions about assessments of soil fertility. Because, as they included all soil factors affecting plant growth, farmers’ perceptions of soil fertility were found to be more long term day-to- day close practical experience finding than those of researchers.

Abstract

The aims of study is to distinguish the different origins of dissolved organic matter and emphasizes the spatial variations of dissolved organic matter quality in Lomé lagoon system composed by three lakes and Equilibrium canal. The results showed that, the three lakes of Lomé are dominated by biological dissolved organic matter (HIX < 4) except the site O11 (HIX = 5.75) with high biological activity (BIX included between 0.8 and 1). This high biological activity could due to the water contribution from north plateau and offshore bar. Apart from O11 and C4 the information brought by the ratio Iγ/Iα shows that the dissolved organic matter of the lagoon is autochthonous and composed by labile organic compounds. Lomé lagoon system is composed in majority by humic substances with a small amount of microbial products.

Abstract

The intensive airstrikes on agricultural lands in the Gaza Strip create craters of 20 m diameter and 10 m depths. Samples from the craters are collected from fourteen different locations, were analyzed to assess the impact of war activities on soil pollution. Soil samples were analyzed for major heavy metals (Ni, Cr, Cu, Mn, Co and Pb) by using hotplate digestion and A Perkin-Elmer Analyst 600 GF-AAS analyzer, equipped with pyrolytically coated graphite tube with integrated platform Zeeman background and correction. The results showed that most of the soils had mean Ni concentration that was over four times higher than the control, Cr was five times, Cu was thirty one times higher, Mn was greatly higher than the control (114 times), Co was five times higher while Pb was twelve times higher than the control. Due to its texture, some samples from sandy soil origins had not significant higher metals concentration than the control. Ni, Cr, Cu, Mn, Co and Pb clearly contributed by the content of munitions of the airstrike. Soil pollution by Cu, Mn and Pb was more widespread than the other heavy metals, which was contributed mostly by munitions. The results also indicate that the concentration of specific heavy metals depends on the type of the explosives material and the soil texture. The current research highlighted the danger and risk of munitions on the agricultural lands. It is highly recommend for the relevant institutions to monitor and follow up research program to investigate the fate of the metals in soil, groundwater and food chain to protect the environment and health.
