Bunge owns one of the most important virtual libraries of fertilization experimentation in Argentina with data from more than 10 years of trials available in the company's agricultural dossiers. Within this framework, the results of studies carried out in different areas of Entre Ríos were shared.
Buenos Aires, August 2019. Fertilization trials have been carried out at different sites in Entre Ríos for the sequence of wheat-soybean crops since 2015. The purpose of these trials was to determine the response to nutrients such as sulphur and zinc, given their importance in the balanced nutrition of crops in general.
The trials were conducted by Bunge in conjunction with various professionals in the departments (districts) of Paraná (El Palenque, Villa Urquiza and Aldea San Francisco); Diamante (Aldea Protestante) and Victoria (Pajonal and Rincón de Nogoyá). These trials were carried out in producers' fields using different varieties of wheat, while double-cropping soybean was planted unfertilized to evaluate the residual effect of fertilizer applied to wheat. Prior to planting, soil analysis was carried out, and nitrogen, sulphur, organic matter, pH, Pe, zinc and boron were determined, with deficit in sulphur and zinc, among others.
“In all cases, responses to nitrogen and sulphur occurred in wheat”, said engineer Hugo Ramírez, Technical Manager of Bunge. “As for zinc, the wheat response occurred in two of the fields: El Palenque and Rincón de Nogoyá. The double-cropping soybean responded to sulfur and zinc in all cases, averaging 398 kg and 197 kg, respectively," the specialist added.
Nitrogen adjustments (Soil N + Fertilizer Nitrogen) ranged from 100 to 160 kg/ha depending on the year and field, while sulphur was adjusted to 15 kg/ha in the corresponding treatments and zinc to 1.2 kg/ha. The fertilizers used were: Sol UAN®, Sol MIX® and Sol MIX® Zinc, incorporating a control without nitrogen fertilization (only the nitrogen from the soil and the phosphate base used by the farmer.
These trials are part of a network that is distributed along all agricultural regions of Argentina. Its objectives are, on the one hand, to contribute knowledge to return to the soil the nutrients extracted in the crops and, on the other, to increase quality and crop productivity.
The information about this research and the research belonging to the Bunge network can be accessed at https://www.bungeargentina.com/ in the Fertilizer - Agricultural dossiers sector. In these archives of more than 10 years of research, Bunge aims to shorten the distance between the usual agricultural yields and those with high fertilization to allow a faster reading of fertilizers, synthesized in dossiers classified by crop, zone and research line.
