Fertilizers and low emission development in sub-Saharan Africa

December 1st, 2016 / Edis, UK

Many countries in Africa included fertilizer use, soil fertility management, and agricultural inputs as part of their contributions to the Paris Climate Agreement. While nitrogen (N) fertilizers contribute substantially to nitrous oxide (N2O) emissions globally, emissions from fertilizers are still low in sub-Saharan Africa. Projections of future food needs in …

Why boosting legume production will lift the gloom for African farmers

September 14th, 2016 / The Conversation, UK

Africa has the lowest use of nitrogen on its farmland compared to other regions of the world. This is because smallholder farmers have limited financial resources to buy fertilisers. Nitrogen is one of the most essential nutrients needed by plants for their growth, development and reproduction. Yet it is depleted …

What can be done about badly depleted nitrogen levels in Africa’s soil

February 26th, 2016 / The Conversation, UK

African soils have been mined for their nutrients for far too long. Nutrients are removed in harvesting across the continent, but they aren’t being returned to the soil. This usually happens in the form of manures or fertilisers. As with a bank so too with soil: if you don’t deposit …

Smallholders gaining from nitrogen-efficient maize

November 10th, 2015 / SciDev.net, UK

Smallholders face challenges such as poor soils and high cost of fertilisers. New improved varieties can raise yields by 30 per cent even in poor soils. Smallholders are seeing the varieties’ impacts, including aiding food security. Read …

Feeding sub-Saharan Africa

October 22nd, 2015 / IntoBiology

In the west, we’ve spent 50 years relying on increasing food yields by adding nitrogen-based fertilisers to the soils. But it’s not an approach that seems to be working for the millions of smallholder farmers across western and central Africa. Local farmers, agronomists and scientists from across the world are …

Nitrogen use efficient rice shows yield increase of 30 %

September 10th, 2015 / Market Watch, US

Major yield increase has the potential to change the economics of rice production and enhance food security. Four years of field trials with a leading line of Nitrogen Use Efficient (NUE) rice have demonstrated an average 30 percent yield increase over conventional controls. These results were reported jointly today by …
