Investigadores del Instituto Nacional de Tecnología Agropecuaria (INTA) de Balcarce, relevaron una deficiencia de zinc en los suelos del sur de la provincia de Buenos Aires, que afecta al rendimiento del trigo y la cebada.
Según el análisis, un 33% de los lotes relevados en el sur bonaerense presentan concentraciones por debajo de 0,80 partes por millón (ppm) nivel de zn, que afecta a los cultivos, ya que en estos números, el rendimiento de trigo puede caer entre 5% y 15% si no se fertiliza.
«En números, un suelo con 0,75 *partes por millón de Zn y un objetivo de 7.000 kilos por hectárea puede perder hasta 840 kilos por hectárea. Ese valor excede ampliamente el costo de la fertilización, que ronda entre 18 y 20 dólares por hectárea, analiza Hernán Sainz Rosas, especialista fertilidad de suelos del INTA Balcarce.
