Nitrogen (N) cycling in mangroves is complex, with rapid turnover of low dissolved N
concentrations, but slow turnover of particulate N. Most N is stored in soils. The largest …

Abstract Nitrate (NO 3−) leaching from agriculture is a growing environmental concern, but
little attention has been given to the cropping systems in sub-Saharan Africa, where efforts …

Slash-and-burn practices and subsequent fallow periods affect soil nitrogen (N) availability.
Although extensive studies have examined the global temporal patterns of inorganic N after …

Contexto: La conformación de conglomerados habitacionales ilegales, en la mayoría de los
casos, sin saneamiento básico adecuado, puede generar deterioro de los recursos …

Rapid litter turnover in tropical forests and during summer seasons might be due to
increases in ligninolytic enzyme activities during warmer periods. We compared ligninolytic …

Some O horizons showed higher nitrification rate than mineral horizons.• Both total N and
pH were positively correlated with nitrification rate in O horizon.• Nutrient richness in litters …

Cassava, one of the most important crops in the tropics is positively affected by the
association with Arbuscular Mycorrhizal Fungi (AMF). Such association is greatly influenced …

In no-tillage systems, there is an accumulation of crop residues (CR), which plays an
essential role in the availability of soil-N. A study was set up to provide information regarding …

Deforestation of native tropical forests has occurred extensively over several decades. The
plantation of fast-growing trees, such as Acacia spp., is expanding rapidly in tropical regions …

Forest-savanna mosaic is widespread in tropical Africa mainly occurring on nutrient-poor
Oxisols. Though sustainable agriculture is a major concern in this region, little is known …
