1 A Success Zinc Story in Turkey and HarvestZinc Project Ismail Cakmak Sabanci University-Istanbul NATO-Zinc Project in Anatolia ( ) Effect of Zinc Fertilization on Wheat Production in Central Anatolia - + 1

2 Effect of soil applications of micronutrients (5 kg ha -1 ) on grain yield of wheat and barley. Experiment was conducted by Mufit Kalayci in Eskisehir (YEAR 1992) Cereals Applications Barley Bread Wheat (tons ha -1 ) Control (all micros) All micros -Mn All micros -Cu All micros -B All micros -Fe All micros Cakmak et al 1998, Field Crops Res. Year 1992: Field tests with and without zinc application No Zinc With Zinc 2

3 Pictures from NATO-Zinc Project in Central Anatolia. Green Areas show the areas treated with Zinc Fertilizers. Project was supported by NATO Science for Stability Program (NATO-SFS) NATO-Science for Stability (NATO - SFS) Project with 1 Million USD Budget Generated a Benefit of 100 Million USD 3

4 Consumption (1000 ton) Use of Zinc Containing Compound Fertilizers after NATO-Zinc Fertilizer Project in Turkey Success Story Years Source: Ministry of Agriculture and Toros Fertilizer Statement of IFA -International Fertilizer Industry Association- 12 April 2005: The Anatolia initiative is one of the world's first examples of using agricultural practices to address public health problems as well as improved crop production, and its success provides a model for countless other nations 4

5 and Fe Deficiencies: Global Malnutrition Problem Iron Estimated 2 billion Zinc Estimated 2 billion Major Reason: Low Dietary Intake High Consumption Cereal Based Foods with Low and Fe Concentrations In number of developing countries cereals contributes nearly 75 % of the daily calorie intake. 5

6 For a better nutrition of human beings, cereal grains should contain around mg kg -1 Current Situation: mg kg -1 elements must be obtained (often) from the soil solution by roots Plants are not able to synthesize mineral nutrients Mineral nutrient must be absorbed by roots (or by leaves) 6

7 There are several soil chemical and physical factors limiting capacity of plants to absorb adequate amount of zinc from soils SOIL high CaCO 3 high ph clay soils low organic matter low soil moisture high Fe and Al oxides Limited uptake Enhanced adsorption and precipitation Solutions to Micronutrient Deficiencies Supplementation Food Fortification Golden Wheat Fortfied with 7

8 Agricultural Solutions (Breeding and Fertilizer Approaches) Breeding Agronomy/Fertilizers Complementary approaches Rapid and Sustainable Solution Application of Zinc Fertilizers: (Agronomic Biofortification) Application of -containing fertilizers offers a rapid solution to the problem 8

15 Economy Based on the knowledge and information collected from our collaborators from Haryana, Punjab, Varanasi, Orissa and Delhi, the cost of a single spray of SO4 by using power-spray ranges is around 15 USD per ha (including the costs for 4 kg SO4 and the costs associated with power-spray and labor). A yield increase of only 1.5 % (+45 kg grain) would cover the costs of foliar application assuming that average grain yield is about 3 tons per ha..

18 Conclusion Foliar application represents a successful, rapid and cost effective practice in biofortification of cereals The positive impact of foliar fertilization occurrs irrespective of the soil and environmental conditions, management practices and cultivars. Foliar fertilizer approach can be locally and quickly adopted for increasing dietary intake in rural areas.
