Precision for smallholder farmers: a small-scale-tailored variable rate fertilizer application kit
Precision agriculture technology at the hands of smallholder farmers in the developing world is often deemed far-fetched. Low-resource farmers, however, are the most susceptible to negative changes in the environment. ...
Evaluation of three field-based methods for quantifying soil carbon
(Public Library of Science, 2013)
Three advanced technologies to measure soil carbon (C) density (g C m−2) are deployed in the field and the results compared against those obtained by the dry combustion (DC) method. The advanced methods are: a) Laser ...
Impact of conservation agriculture on catchment runoff and soil loss under changing climate conditions in May Zeg-zeg (Ethiopia)
This study evaluates the practice of conservation agriculture (CA) in the May Zeg-zeg catchment (MZZ; 187 ha) in the North Ethiopian Highlands as a soil management technique for reducing soil loss and runoff, and assesses ...
Conservation agriculture, increased organic carbon in the top-soil macro-aggregates and reduced soil CO2 emissions
Background and aims: Conservation agriculture, the combination of minimal soil movement (zero or reduced tillage), crop residue retention and crop rotation, might have the potential to increase soil organic C content and ...
Climate change and agriculture: adaptation strategies and mitigation opportunities for food security in South Asia and Latin America
During the past two centuries, the world has witnessed a remarkable increase in the atmospheric concentrations of the greenhouse gases (GHGs), namely carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), as a result ...
Bacterial diversity as affected by tillage practice in a raised bed planting system
Carbon and nitrogen dynamics are altered by tillage so it was hypothesized that the composition of the microbial population that control these processes was affected too. Soil was sampled from conventional beds (CB) tilled ...
