Utilis) On Soil Carbon In An Ultisol Under Maize Cultivation In Southern Benin", "description": "<p>Abstract.  Long term fallow is no longer possible in densely populated tropical areas, but legume cover crops can help maintain soil fertility. Our work aimed to study changes in soil carbon in a sandy loam Ultisol in Benin, which involved a 12\uffe2\uff80\uff90year experiment on three maize cropping systems under manual tillage: traditional no\uffe2\uff80\uff90input cultivation (T), mineral fertilized cultivation (NPK), and association with Mucuna pruriens (M). The origin of soil carbon was also determined through the natural abundance of soil and biomass 13C. In T, NPK and M changes in soil carbon at 0\uffe2\uff80\uff9340 cm were \uffe2\uff88\uff920.2, +0.2 and +1.3 t C ha\uffe2\uff88\uff921 yr\uffe2\uff88\uff921, with residue carbon amounting to 3.5, 6.4 and 10.0 t C ha\uffe2\uff88\uff921 yr\uffe2\uff88\uff921, respectively. After 12 years of experimentation, carbon originating from maize in litter\uffe2\uff80\uff90plus\uffe2\uff80\uff90soil (0\uffe2\uff80\uff9340 cm) represented less than 4% of both total carbon and overall maize residue carbon. In contrast, carbon originating from mucuna in litter\uffe2\uff80\uff90plus\uffe2\uff80\uff90soil represented more than 50% of both total carbon and overall mucuna residue carbon in M, possibly due to accelerated mineralization of native soil carbon (priming effect) and slow mulch decomposition. Carbon originating from weeds in litter\uffe2\uff80\uff90plus\uffe2\uff80\uff90soil represented c. 10% of both total carbon and overall weed residue carbon in T and NPK. Thus mucuna mulch was very effective in promoting carbon sequestration in the soil studied.</p>", "keywords": ["Soil nutrients", "Carbon sequestration", "13C natural abundance", "[SDE] Environmental Sciences", "Soil management", "http://aims.fao.org/aos/agrovoc/c_7170", "Npk", "SOL CULTIVE", "F08 - Syst\u00e8mes et modes de culture", "Soil fertility", "Zea mays", "http://aims.fao.org/aos/agrovoc/c_875", "630", "plante de couverture", "Legume cover crops", "Benin", "http://aims.fao.org/aos/agrovoc/c_1301", "legume cover crop", "Mucuna pruriens", "http://aims.fao.org/aos/agrovoc/c_4971", "ANALYSE STATISTIQUE", "580", "LEGUMINEUSE TROPICALE", "Acrisol", "2.
