Soybean Yields in Argentina Lagging Due to Management Gaps, Research shows
BUENOS AIRES – Argentine soybean production is currently realizing only 72% of its potential due to insufficient management practices, including suboptimal fertilization and crop rotation, according to recent research highlighted by TodoAgro. A study revealed a meaningful 28% gap between achievable yields and current results,pinpointing a lack of attention to key agronomic factors as the primary driver.
The research, led by Di Mauro, emphasized the critical role of sowing date, crop rotation, and phosphate fertilization. Plots following corn predecessors exhibited fewer gaps compared to continuous soybean cultivation. However, a survey indicated that only half of producers currently fertilize soybeans, often applying doses below the crop’s actual requirements.
Beyond yield, the study explored the link between fertilization and grain quality, finding that phosphorus and sulfur fertilization increased grain protein content by up to 0.9%. While the market doesn’t currently offer a premium for higher protein levels, Di Mauro noted the industrial benefits, stating, “It sounds little, but moving 1% of protein wiht management is a lot.” He further emphasized that improved yield and protein content were simultaneously achieved in over half of the evaluated plots.
The research group aims to develop agronomic practices that enhance both primary production and value throughout the soybean chain, recognizing that higher protein content translates to more valuable flours for processing industries.
