The Climate Technology Centre and Network (CTCN) is seeking a national consultant from Zambia to develop a technology roadmap on conservation farming with agro-forestry. The technology roadmap is expected to serve as a tool to assess feasibility, develop business and financial models for bankable projects and prepare for investment. Deadline for applications: 8 August 2017.
Efficient use of nitrogenous fertilisers can reduce N2O emissions from agricultural fields. In addition, by reducing the quantity of synthetic fertilisers required, improved management can also reduce CO2 emissions associated with their manufacture. In this article a variety of fertiliser management technologies are discussed in brief, followed by a discussion on their relative advantages and disadvantages.
Soil is a fundamental requirement for crop production as it provides plants with anchorage, water and nutrients. A certain supply of mineral and organic nutrient sources is present in soils, but these often have to be supplemented with external applications, or fertilisers, for better plant growth. Fertilisers enhance soil fertility and are applied to promote plant growth, improve crop yields and support agricultural intensification.
