“…After six years of amendment, CTS increased the organic C content in the soil because the waste has a high content of organic matter (Table 1). Our results are in agreement with those of others studies, which reported increased organic C contents after compost amendment (Garba, Cornelis, & Steppe, 2011;Arthur, Cornelis, & Razaghi, 2012). The soil pH increased after six years of CTS amendment, which is contrary to the general belief that organic residues decrease soil pH via the production of acids formed during the decomposition of organic matter.…”

ABSTRACT. This study evaluated soil properties and cowpea yield after six years of consecutive amendment of composted tannery sludge. The compost was applied annually at 0, 2.5, 5, 10, and 20 Mg ha -1 and at the end of the sixth year, the chemical and physical properties of the soil were evaluated using a randomized block design. The Cr, P, K, Ca, Na and organic C contents and the pH and cation exchange capacity increased linearly after six years of compost amendment. The soil bulk density decreased linearly while the aggregate stability index increased after compost amendment. As a consequence of the changes in the chemical and physical properties of the soil, cowpea yield showed a quadratic response to the tannery rates, with an estimated maximum cowpea yield at 8.3 Mg ha -1 . In conclusion, the soil chemical and physical properties improved after six years of composted tannery sludge amendment. However, the soil pH and the Cr and Na contents increased with composted tannery sludge amendment, which influenced the cowpea yield and resulted in a quadratic response to the compost.Keywords: waste management, soil fertility, soil quality.Propriedades do solo e produtividade do feijão-caupi após seis anos de aplicações consecutivas de lodo de curtume compostado RESUMO. Este estudo avaliou as propriedades do solo e a produtividade do feijão-caupi após seis anos de aplicações consecutivas de lodo de curtume compostado. Anualmente, o composto foi aplicado a 0, 2,5, 5, 10 e 20 Mg ha -1 e no sexto ano as propriedades químicas e físicas do solo e a produtividade do feijão-caupi foram avaliadas em experimento de blocos casualizados. Cr, P, K, C orgânico, pH, Ca, Na, e a capacidade de troca de cátions aumentaram linearmente após seis anos de aplicação do composto. A densidade do solo diminuiu linearmente enquanto a estabilidade de agregados aumentou após a aplicação do composto. Em consequência das mudanças nas propriedades químicas e físicas do solo, a produtividade do feijão-caupi apresentou resposta quadrática às doses de lodo de curtume compostado com máxima produtividade estimada encontrada na dose de 8,3 Mg ha -1 . Em conclusão, as propriedades químicas e físicas do solo melhoraram após seis anos de aplicação do lodo de curtume compostado. Entretanto, o pH do solo, bem como os teores de Cr e Na aumentaram com aplicação do lodo de curtume compostado e estes parâmetros influenciaram a produtividade do feijão-caupi que apresentou resposta quadrática.Palavras-chave: manejo de resíduos, fertilidade do solo, qualidade do solo.

The Effect of Water and Soil Conservation (WSC) on the Soil Chemical, Biological, and Physical Quality of a Plinthosol in Niger

The hazard for recurring food insecurity in the Sahel is largely affected by insufficient biomass productivity of degraded, marginal lands. In general, water and soil conservation (WSC) techniques are believed to tackle the deterioration of soil quality by enhancing soil hydraulic properties, soil life, and soil organic carbon (SOC) content, but this beneficial effect on soil quality is hardly ever quantified in WSC research. This study therefore evaluates the effect of WSC on soil chemical, physical, and biological quality indicators by means of an in situ experiment, which was installed in 2011 nearby Sadoré, Niger. The treatments include the following: zaï + manure (Z), demi‐lunes + manure, scarification + manure, control + manure, and control. WSC increases grain yields up to 0·7 ± 0·2 Mg ha−1 on degraded, marginal lands, which is similar to yields produced on fertile lands in the area. Nevertheless, a trade‐off between biomass production and SOC accumulation was observed. After three growing seasons, SOC was found to rise significantly for the treatments provided with manure, from ±2·5 to ±5 g kg−1, but the increase was lowest for Z, which produced the highest yields. WSC also showed significantly elevated nematode counts but did not considerably affect other soil chemical and soil physical properties. Hence, on the short term, WSC does not improve soil quality, as was widely proclaimed. Therefore, future research should include the assessment of long‐term WSC effects and the evaluation of integrated management combining WSC with alternative, yield‐enhancing strategies.

“…Termites are dominant members of the soil arthropod community in all tropical ecosystems, and their biomass may represent up to 95% of the total soil arthropod abundance (Eggleton et al, 1998;Bignell & Eggleton, 2000). As ecosystem engineers, termites are responsible for large-scale bioturbation, soil aeration, and organic matter decomposition, altering physical, chemical, and biological properties of soils, which in turn affect plant growth and diversity (Garba et al, 2011;Van der Plas et al, 2013;Jouquet et al, 2015). The decomposition of complex organic matter into nutrients available for plants is one of the most important ecosystem services termites provide to tropical forests, which leads to ecosystem stabilisation under global change (Obi & Ogunkunle, 2009;Bonachela et al, 2015;Veldhuis et al, 2017).…”

1. While it is clear that land‐use change significantly impacts the taxonomic dimension of soil biodiversity, how the functional dimension responds to land‐use change is less well understood. 2. This study examined how the transformation of primary forests into rubber tree monocultures impacts individual termite species and how this change is reflected in termite taxonomic and functional α‐diversity (within site) and β‐diversity (among sites). 3. Overall, individual species responded strongly to land‐use change, whereby only 11 of the 27 species found were able to tolerate both habitats. These differences caused a 27% reduction in termite taxonomic richness and reduced taxonomic β‐diversity in rubber plantations compared with primary forests. The study also revealed that the forest conversion led to a shift in some termite species with smaller body size, shorter legs and smaller mandibular traits. Primary forests exhibited higher functional richness and functional β‐diversity of termite species, indicating that functional traits of termite species in rubber plantations are more evenly distributed. 4. The present study suggests that forest conversion does not merely decrease taxonomic diversity of termites, but also exerts functional trait filtering within some termite species. The results affirm the need for biodiversity assessments that combine taxonomic and functional indicators when monitoring the impact of land‐use change.
