Soil micronutrient supply and grain quality for human nutrition in selected parts of Morogoro, Tanzania

Abstract: 
Soils worldwide have become depleted of micronutrients. This has resulted in an increase in micronutrient deficiency diseases for people consuming micronutrient poor foods as a sole source of nutrition. This study was carried out to determine whether low-input farming is producing micronutrient deficient foods in selected areas of Morogoro region of Tanzania. It was found that some of the soils were not deficient in zinc, iron and copper. Maize grain was deficient in human dietary zinc and iron when compared against set targeted levels. Maize grain zinc ranged from (7.11-43.60)μg/g while the iron ranged from (16.55-39.96) μg/g.
Les sols dans le monde entier sont de plus en plus épuisés des micronutriments. Ceci a eu comme conséquence une augmentation des maladies d’insuffisance en micronutriments pour les populations consommant des nourritures pauvres en micronutriments comme source unique de nutrition. Cette étude a été effectuée pour déterminer si l’agriculture de faible demande produit les nourritures déficientes en micronutriments dans des régions choisies de Morogoro en Tanzanie. On a constaté que certains sols n’avaient pas une carence en zinc, fer et cuivre. Le grain de maïs avait une carence en zinc et fer diététiques humains une fois comparé aux niveaux d’ensemble visés. Le zinc de grain de maïs s’est étendu (de 7.11 à 43.60) μg/g tandis que le fer s’étendait (de 16.55 à 39.96) μg/g.

About the RUFORUM 2010 Biennal Conference
"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholders in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme of Food Science"
