Evolution of nutrients element content in soils dedicated to onion crop Evolución del contenido de elementos nutrientes en suelos cultivados con cebolla de bulbo

Abstract

To determine the evolution of nutrient content in soils dedicated to commercial onion crop (Allium. cepa) in the municipality of Tibasosa, Boyacá,Colombia, in a Sulfic endoaquepts soil, three treatments established: Without fertilization (T1), conventional fertilization used in the area (T2) and fertilization according to analysis of soils (T3). Samples were collected for analysis 20 days before plantation and 45, 90 and 120 days after sowing. The of contents macroelements showed the following order N>Ca>K>Mg>S>P and those of micronutrients, Mn>Fe>Zn>Cu>B. There were positive interactions among N/Fe, P/K, P/Ca, P/Mg, K/Mg, K/S, Mg/S, B/Zn and Cu/Mn and negative interactions among N/K, N/S, P/Fe, K/Fe, Mg/Fe, B/Fe, S/Fe, Cu/Zn and Zn/Mn affecting their concentration and availability. The results evidence that a balanced content of nutrients can increase the yield. Key words: Allium cepa, Sulfic endoaquepts, Fertility.El objetivo del estudio fue determinar la evolución del contenido de nutrientes en suelos destinados al cultivo comercial de cebolla de bulbo (Allium cepa) en el municipio de Tibasosa, Boyacá. En un suelo sulfic endoaquepts se establecieron tres tratamientos: Sin fertilización (T1), con fertilización convencional de la zona (T2) y fertilización con base en el análisis de suelos (T3). Se recolectaron muestras para análisis 20 días antes de la siembra y a los 45, 90 y 120 días después de la siembra (DDS). Los contenidos de macroelementos se presentaron en el orden N>Ca>K>Mg>S>P y los de micronutrientes Mn>Fe>Zn>Cu>B existiendo interacciones positivas entre N/Fe, P/K, P/Ca, P/Mg, K/Mg, K/S, Mg/S, B/Zn y Cu/Mn y negativas entre N/K, N/S, P/Fe, K/Fe, Mg/Fe, B/Fe, S/Fe, Cu/Zn y Zn/Mn afectando su concentración y disponibilidad. Los análisis permitieron inducir que un contenido adecuado de nutrientes incrementa el rendimiento en la zona. Palabras claves: Allium cepa, Sulfic endoaquepts, Fertilidad.
