Multiple nutrient limitation of the soil micro-food web in a tropical grassland revealed by nutrient-omission fertilization

Jean Trap, Manoa Raminoarison, Aurélie Cébron, Kanto Razanamalala et autres

Although involved in key functions of the terrestrial ecosystems, the activity and the diversity of soil microorganisms can be severely limited by energy and nutrients in weathered tropical soils. To optimize nutrient cycling for crop nutrition, assessing which nutrients limit the activity …

Diogo Néia Eberhardt, Robélio Leandro Marchão, Pedro Rodolfo Siqueira Vendrame, Marc Corbeels et autres

A presente obra é um marco para a ciência agrícola nos trópicos ao evidenciar que os importantes avanços conquistados nas décadas passadas, que fizeram do Brasil o único país do mundo com agricultura diversificada e competitiva, foram fundamentais, mas fazem parte de …

Short-Term PE Generation Processes in the Soils of a Farmer Plots Network in the Madagascar Highlands: Actors and Drivers

Kanto Razanamalala, Tantely Razafimbelo, Pierre-Alain Maron, Lionel Ranjard et autres

Carbon sequestration in agricultural soils, through the accumulation of high-quality organic matter, represents great potential to mitigate climate change and simultaneously improve soil fertility. Such a challenge is particularly important and relevant in developing tropical countries like Madagascar, where soil carbon storage …

Effect of Rhizobium Inoculation on Growth of Common Bean in Low-Fertility Tropical Soil Amended with Phosphorus and Lime

Harimenja Razafintsalama, Jean Trap, Bodovololona Rabary, Adamson Tsoushima Ernest Razakatiana et autres

The cultivation of grain legumes (e.g., common bean) in sub-Saharan Africa contributes to the provision of food for a growing population and delivers environmental benefits such as inputs of nitrogen (N) to crops and soil via symbiotic nitrogen fixation (SNF). However, the …
