In: Fertilizer ResearchSummary: Se revisa la investigacion realizada sobre las necesidades de micronutrimentos de cultivos alimenticios tropicales. Se discute la funcion de los micronutrimentos (Cu, Mo, Fe, Zn, Mn y B) en los cultivos. Se hace una breve referencia a la yuca relacionada con un ensayo de encalamiento y micronutrimentos adelantado en CIAT en Colombia, en el cual altos niveles de encalamiento indujeron una deficiencia de Zn y redujeron la absorcion de Mn, Cu y B. La yuca extrae 200 g de Fe, 75 g de Mn, 25 g de B, 75 g de Zn y 8 g de cu/t de MS. Se indican las necesidades generales de investigacion sobre este tema. (CIAT)Summary: Research conducted on micronutrient needs of tropical food crops is reviewed. The role of micronutrients (Cu, Mo, Fe, Zn, Mn, and B) in crops is discussed. A brief reference to cassava is made regarding a lime and micronutrient trial conducted by CIAT in Colombia where high levels of liming induced Zn deficiency and reduced the uptake of Mn, Cu, and B. Cassava removes 200 g Fe, 75 g Mn, 25 g B, 75 g Zn, and 8 g Cu/t DM. General research needs on the topic are indicated. (CIAT)
