Agriculture production as a major driver of the Earth system exceeding planetary boundaries

Autor: Campbell, Bruce M. Beare, Douglas J. Bennett, Elena M. Hall-Spencer, Jason M. Ingram, John S. I. Jaramillo, Fernando Ortiz, R. Ramankutty, Navin Sayer, Jeffrey A. Shindell, Drew

We explore the role of agriculture in destabilizing the Earth system at the planetary scale, through examining nine planetary boundaries, or “safe limits”: land-system change, freshwater use, biogeochemical flows, biosphere integrity, climate change, ocean acidification, stratospheric ozone deple...

Effects of organic and mineral fertilizer nitrogen on greenhouse gas emissions and plant-captured carbon under maize cropping in Zimbabwe

Autor: Mapanda, Farai Wuta, Menas Nyamangara, Justice Rees, RM

Optimizing a three-way pact comprising crop yields, fertility inputs and greenhouse gases may minimize the contribution of croplands to global warming. Fluxes of N2O, CO2 and CH4 from soil were measured under maize (Zea mays L.) grown using 0, 60 and 120 kg N hm-2 as NH4NO3-N and composted manure...

Feed factors affecting nutrient excretion by ruminants and the fate of nutrients when applied to soil

Autor: Somda, Z.C. Powell, J.M. Fernández Rivera, S. Reed, J.D.

Mixed farming systems in semi-arid West Africa rely on recycling organically bound nutrients to maintain soil productivity. The passage of plant biomass through ruminant livestock plays a major role in the nutrient cycles of this region. The feeding value of crop residues and browses and their im...
