The present proposal addresses the continuation of two long-term experiments initiated and conducted to date within the project NUCLEUS: An associated virtual center to promote improvements in the efficiency of nitrogen use in the UK and Brazil through soil- integrated plant. The subproject 1 - Nitrogen fertilization for maize/forage in rotation with soybean and its effects on in soybean …
Our specific aims are to: 1. Bring together some of the UK and Brazil's top ranked institutes and leading researchers. 2. To deploy specific work packages (WP) that address important research gaps in our understanding to improve NUE and priorities for Brazil including WP1: Use of Sensor Technologies to Improve NUE in Crop Production; WP2: Linking the Impacts of Soil Physical Condition and…

The adjustment of nitrogen fertilization is essential to improve the efficiency of N use and maize yield, but little is known about the impact of the early fertilization with nitrogen on yield and N losses by leaching, and whether this is dependent on the source of nitrogen. The objective of the study is to evaluate the nitrate leaching in the soil profile, as well as the nutrition and yi…
Understanding the carbon flow (C) is essential for soil conservation and agriculture management in the context of climate change. The dynamics of C and nitrogen (N) in intercropped systems is complex and little is known about their implications for stabilization, persistence and C flow in fractions of Soil Organic Matter (SOM). The objective is to evaluate the effect of N supply in consor…
Peanuts are grown mainly in sandy soils with low phosphorus availability, although there may be non-labile phosphorus due to previous fertilization. There are reports that peanuts are efficient in absorbing P in less labile ways. On the other hand, currently the cultivars are more productive than those of the past, so that fertilization has been carried out empirically, with the need to e…
Nitrogen is the nutrient absorbed in the greatest amount by the cotton plant, and approximately 43% of the amount absorbed and exported from the production field. It happens that, due to the possibility of losses, the efficiency of use of nitrogen fertilizer has been low. Recently, studies have been released showing that the use of omeprazole, a drug that regulates the activity of the pro…
In oxidic soils, phosphorus is considered the most limiting nutrient for crop productivity because the phenomenon of adsorption occurs, due to its limited availability by adsorption reactions that immobilize the P in the fertilizer. Thus, the soil behaves as a drain of P, being adsorbed or complexed, giving rise to labile phosphorus (available to plants) and non-labile phosphorus (unavail…
Understanding the nitrification process (conversion of NH4+ ammonium to NO3- nitrate) within long-term conservation production systems intercropped with forages in tropical soils and climate is essential for sustainable management and management of N in the environment. Research have shown divergent effects regarding the inhibitory potential of forage species related to nitrification, whi…

Phosphorus (P) is one of the main limiting factors for crop productivity in tropical weathered soils due to its high adsorption with iron and aluminum oxides. One of the strategies to improve P use efficiency is to use crops and/or cultivars with greater P use efficiency. Peanut is considered a species with high P use efficiency, but it is still unknown whether this efficiency is dependen…
The effect of no-till on soil C accumulation is well known, and soil labile C has been related to the amount of straw in the system (Tivet et al., 2013). However, the accumulation of stable C, bound to soil minerals, is more interesting because of its greater resilience. Agricultural conservation systems are known to improve soil aggregation (Madari et al., 2005), and smaller aggregates a…
Land-based solutions to mitigate the global climate change crisis require the adoption of sustainable agriculture management practices. Intercropped systems - maize-forages cropped simultaneously - are key strategies to increase soil carbon (C) sequestration and agricultural resilience to extreme weather events. The complex biogeochemical C and nitrogen (N) dynamics is a challenge for soi…
