The Effects of Crop Rotation and Nitrogen Fertilization on Soil Chemical and Microbial Properties in a Guinea Savanna Alfisol of Nigeria

Abstract: The impacts of crop rotation and inorganic nitrogen fertilization on soil microbial biomass C (SMBC) and N (SMBN) and water-soluble organic C (WSOC) were studied in a Guinea savanna Alfisol of Nigeria. In 2001, fields of grain legumes (soybean and cowpea), herbaceous legume (Centrosema pascuorum) and a natural fallow were established. In 2002, maize was planted with N fertilizer rates of 0, 20, 40 and 60 kg N ha )1 in a split-plot arrangement fitted to a randomized complete block design with legumes and fallow… Show more

“…pH and available N (Alvey et al, 2001) and biological properties i.e. higher microbial biomass C and N, respiration rate, ATP content and early mycorrhizal infection (Adeboye et al, 2006;Jemo et al, 2006). Apart from this, some legumes also sequester heavy metals in nodules, roots, stem, leaves and vacuoles (Georgiev et al, 1996).…”

“…The results also show that MBC values in the “cultivated soils are inferior to those of sub‐humid tropical and Guinea savanna (Nsabimana et al ., ; Adeboye et al ., ; Adeboye et al ., ), probably because of shallow sampling depth (10 cm) and higher nutrient inputs in those soils. Consequently, we found a low microbial contribution to SOC only near the lower limit of 0 · 9–2 · 8% (Anderson & Domsch, ; Chodak & Niklińska, ; Joergensen, ).…”

“…Con respecto a las demás zonas experimentales este efecto no resultó igual. Adeboye et al (2006) demostraron que la fertilización química no presenta un efecto significativo sobre la biomasa microbiana del suelo, pero si la rotación del cultivo. También demostraron que el flujo de la biomasa microbiana del suelo está determinado por el pH y el carbono orgánico presente en el suelo.…”
