Biological nitrogen (N2) fixation in both free-living and symbiotic organisms is an energy-requiring process dependent upon a supply of carbon and energy. In this paper the energy costs for N2 fixation and nodule respiration in symbiotic systems are compared with those of free-living N2-fixing sy...

Costa Rica impulsa a sus sectores a ser carbono neutral en el 2021 y uno de sus principales es el caficultor. El café tiene un gran aporte en la economía, cultura y sociedad en Costa Rica, pues es el medio de vida de 47182 productores en todo el país (ICAFE, 2015) además aporta un 5.2% del PIB ag...

Soil carbon enhancing practices (SCEPs) have been proven to be low-cost solutions in enhancing agricultural productivity and alleviate the detrimental effects of climate change. These practices can be adopted as complementary or as substitute practices due to their associated ecological benefits ...


Kanyenji, George MagamboOluoch-Kosura,WillisOnyango, Cecilia MoraaNg’ang’a, Stanley Karanja[Does the adoption of soil carbon enhancing practices pay off? Evidence on maize yields from Western Kenya.]Does the adoption of soil carbon enhancing practices pay off? Evidence on maize yields from Western Kenya.

Sustainable agricultural practices that enhance soil carbon simultaneously improve farm yields and income. Despite the expansive literature on adoption of soil carbon practices in Kenya, there is limited information on the impact of the elemental practices on farm output. This study attempts to f...

Water drainage is an important mitigation option for reducing CH4 (methane) emissions from residue-amended paddy soils. Several studies have indicated a long-term reduction in CH4 emissions, even after re-flooding, suggesting that the mechanism goes beyond creating temporary oxidized conditions i...

Common bean (Phaseolus vulgaris L.) is the most important food legume in the diet of poor people in the tropics. Drought causes severe yield loss in this crop. Identification of traits associated with drought resistance contributes to improving the process of generating bean genotypes adapted to ...

To assess the efficiency of seven treatments including biochars produced from dried faecal matter and manures as stabilizing agents of cadmium (Cd)-spiked soils, lettuce was grown in glasshouse on two contrasting soils. The soils used were moderately fertile silty loam and less fertile sandy loam...

In 1998, Fisher et al. attempted to draw together published and anecdotal information to answer some of the questions raised by the findings of Fisher et al. (1994; 1995), that introduced pastures of African grasses on the eastern plains of Colombia accumulated large amounts of C in the soil. Thi...
