“…Between 2006 and 2017, soybean harvests were shortened (from October to January). The idea of shortening soybean harvests was mainly to allow for increased production of maize and cotton (Borges et al, 2015). The second harvest in the VRW is represented by 70%-80% maize production and 20%-30% cotton production (Figure S1).…”

The exponential growth of anthropogenic activities over the last century has altered the biogeochemical cycles on a global level (Sutton et al., 2013). The scale of these changes has increased the need to develop joint approaches that both optimize nutrient flows and produce food, fiber, and energy for the growing societal demand. This has to be done while reducing threats to social and economic well-being, such as climate change, ecosystem services and human health threats (UNEP, 2019). Nitrous oxide (N 2 O), nitrogen oxide (NO x) and ammonia (NH 3) emissions, and losses of nitrogen (N) and phosphorus (P) compounds to water systems, are some of the direct consequences of changes in the biogeochemical cycles. These emissions and other losses affect the sustainable use of natural resources, human health, resource management, livelihoods, and economies (Abrol et al., 2017; Sutton et al., 2013; van Grinsven et al., 2013). The production of enough food to meet human demand could threaten the environment and human health if nutrients are not adequately used and managed in the process. Disruptions to aquatic systems, such as eutrophication, or impact on the climate, are examples of the result of unbalanced nutrient use (Oenema et al., 2009). In contrast, when nutrients are insufficiently used in agricultural production, it can increase the risk of land-use changes from associated agricultural incursions into pristine ecosystems and depletion of nutrients and organic matter in agricultural soils, thus leading to soil degradation and increasing the risk of erosion (
