Food and Nutrition Security in Africa, Strengthening Capacity for Diagnosis and Management of Soil Micronutrient Deficiencies in Sub-Saharan Africa for Improved Plant, Animal and Human Nutrition, Mercy Nyambura

  1. 1. 16 June 2014, Helsinki, Finland FoodAfrica Midterm Seminar Food and Nutrition Security in Africa Strengthening Capacity for Diagnosis and Management of Soil Micronutrient Deficiencies in Sub-Saharan Africa for Improved Plant, Animal and Human Nutrition Healthy soils Healthy crops Healthy livestock Healthy people Esala Martti, Keith D. Shepherd, Mercy Nyambura, Riikka Keskinen and Michael Gatari
  2. 2. 16 June 2014, Helsinki, Finland  To develop new, rapid, low cost soil-plant analytical methods for diagnosing soil micronutrient deficiencies for crop, livestock and human health.  To establish a baseline on soil micronutrient status in sub-Saharan Africa soils.  To provide information for various stakeholders on management strategies and options for tackling key micronutrient deficiencies.  To strengthen African capacity on new science and technology for soil-plant micronutrient analysis, diagnosis and management. Project Objectives
  3. 3. 16 June 2014, Helsinki, Finland MTT Agrifood Research Handheld XRFInfrared spectroscopy Total X-ray fluorescence spectroscopy X-ray diffraction spectroscopy ICRAF AAAc-EDTA extractable Cu, Fe, Mn, Zn, Al, Cd, Cr, Mo, Ni, Pb, V Hot water extractable B, Se Aqua regia total element analysis – Pot plants and soils Spectral fingerprinting Reference methods 1. Analytical protocols and guidelines Protocols for analysis of soil micronutrients using new spectral and conventional analytical methods were refined and made available to partners (June 2014) (Completed) Progress Highlights
  4. 4. 16 June 2014, Helsinki, Finland 2.

Results Snap Shot Total and soluble concentrations of micronutrients in the top- and subsoils of Sub-Saharan Africa- first results of 850 samples • No marked differences in the concentrations of the easily soluble elements between top- and subsoil. • The median concentrations of soluble Cu (1.3 mg l-1), Zn (0.8 mg l-1), B (0.4 mg l-1) and Fe (64 mg l-1) in low relative to sufficiency guidelines for good crop growth. • On average 2% of the total content of Fe in the soil was soluble in AAAc-EDTA extractant, Zn 6%, Cu 13% and Mn 39%.
