Background: Agriculture is the single largest geo-engineering initiative that humans have initiated on planet Earth, largely through the introduction of unprecedented amounts of reactive nitrogen (N) into ecosystems. A major portion of this reactive N applied as fertilizer leaks into the environm...

Agriculture and livestock production systems are two major emitters of greenhouse gases. Methane with a GWP (global warming potential) of 21, and nitrous oxide (N2O) with a GWP of 300, are largely emitted from animal production agriculture, where livestock production is based on pasture and feed ...

Management of harvested (senescent) banana pseudostems has implications for efficiency of nutrient use for sole cropped as well as intercropped bananas. Two studies were conducted on aspects of nutrient flows from senescent pseudostems. Sixty one and 55% of the initial N and P, respectively, in s...

A longterm experiment was conducted on Alfisols at Ibadan, Nigeria, to assess agricultural productivity and sustainability of different farming systems. The experiment, conducted for a 10 year period from 1979 to 1988, was implemented in two phases. The effects of methods of land clearing on crop...

At the 21st session of the United Nations Framework Convention on Climate Change (UNFCCC, COP21), a voluntary action plan, the ‘4 per 1000 Initiative: Soils for Food Security and Climate’ was proposed under the Agenda for Action. The Initiative underlines the role of soil organic matter (SOM) in ...

Black carbon (BC) is a quantitatively important C pool in the global C cycle due to its relative recalcitrance compared with other C pools. However, mechanisms of BC oxidation and accompanying molecular changes are largely unknown. In this study, the long-term dynamics in quality and quantity of ...

Identification of tree species or cultivars/provenances that are tolerant to low levels of available soil P will decrease the dependence on P fertilizer for the good establishment and growth of N2-fixing trees. The effects of phosphorus uptake and use efficiency on N2 fixation and growth of prove...
