“…Black oat may provide highquality feed for cattle (Restelatto et al, 2014). Moreover, the plant residues can release significant amounts of N, P, and K, which are majorly available up to 30-40 days from crop management (biomass deposition on the soil surface) (Crusciol et al, 2008), benefiting grain yield of succeeding crops, such as soybean (Caires et al, 2017). When black oat is cultivated for forage in tropical and subtropical production systems, the plants can regrow for at least 40 days before planting the summer crops-sufficient time for a considerable biomass and nutrient accumulation (Vega-García et al, 2020).…”

Under continuous no-till, gypsum has been successfully used to manage soil fertility and improve crop yield. Nitrogen (N) fertilization is critical for crop performance, however, since it is expensive and potentially pollutant, it must be correctly applied. Both subjects have been widely studied, yet there is a lack of information on the interaction between them, especially concerning crops in rotation or succession. The objectives of this study were to evaluate topdressing N fertilization (0, 50, and 100 kg N ha −1 ) on black oat (Avena strigosa Schreb.) under no-till, inside a long-term gypsum experiment (0, 3, 6, 9, and 12 Mg ha −1 ). We evaluated black oat regrowth after haylage harvest and nutrient concentration and uptake by aboveground biomass, as well as the effects of this system on the successor crop soybean (Glycine max (L.) Merr.) in terms of leaf nutrient concentration and grain yield over two growing seasons. The gypsum application, even up to 44 and 55 months earlier, presented a long-term effect when associated with N fertilization, causing black oat biomass to increase during the regrowth phase. Nitrogen fertilization increased black oat regrowth biomass, even without gypsum. Greater nutrient uptake by black oat regrowth occurred under higher gypsum rates and N fertilization, which may have been advantageous in the long term for the production system, once nutrient cycling may partially substitute fertilizer-derived nutrients. Soybean yield was not affected by either long-term gypsum or N applied at black oat tillering, even though some leaf nutrient concentrations were influenced.

“…Soybeans are the fastest growing crop in the world and Brazil is the second-largest producer in the world (Martins et al, 2018). The use of phosphate fertilizers is one of the main strategies for the best crop yield (Caires et al, 2017). Threfore, the use of phosphate fertilizers in soybean crops has become a source of accumulation of trace elements for agricultural land use.…”

In this review, we present information about the presence of trace elements on streams and the consequences related to the increase of these chemical elements on aquatic systems. Although several studies on trace elements contamination in aquatic environments are conducted on point sources, non-point sources also have a high potential to contaminate water bodies. Some trace elements are important for the development of an organism. However, even essential elements, in high concentrations, may be toxic to aquatic organisms. In some cases, trace elements may accumulate and be transferred along food webs, generating changes in the structure and functioning of terrestrial ecosystems. The phytoremediation techniques could be an important tool in reducing the problems generated by trace elements. Thus, understanding the effects generated by the increase of trace elements concentrations on aquatic ecosystems becomes important to help public managers to apply solutions for the mitigation of this chemical pollution on natural resources.

“…It is growth in large areas, previously cultivated with degraded pastures (Feba, Moro, & Guerra, 2017). Due to its soils are naturally low in fertility, fertilization adjustments are necessary to establish a productive system (Caires, Sharr, Joris, Haliski, & Bini, 2017). In this scenario the Mato Grosso State Cerrado (Savanna) stands out, which holds the Brazilian largest soybean production area.…”

“…This deadlock occurs due to the mineralogical knowledge low utilization of the cultivated soils, and therefore, the decision on the total fertilizer to be used, is still based only on the crop requirement, expected productivity, and soil clay content (Caires et al, 2017). Because of this, the results are many times unsatisfactory, because this fertilization do not meet the requirements of the crop, since much of the P applied can be complexed or fixed by the soil constituents (Pavinato, Merlin, & Rosolem, 2009;Pinto, Souza, Paulino, Curi, & Carneiro, 2013).…”

The low natural fertility of tropical soils and the mineralogy almost dominated by iron and aluminum oxides limit the availability of phosphorus (P) to the plants, causing negative impacts on soybean yield. Objective was to evaluate the effect of phosphate fertilization on soils with different maximum phosphorus adsorption capacities (PAC) in soybean development. The experiment was carried out under greenhouse conditions, using Red-yellow Latosol (RYL) and a Typic Hapludalf (TH) soil as substrate. The analyses were performed by a completely randomized experimental design in a 5 × 2 factorial arrangement with three replications. The treatments consisted of 5 doses of P applied, corresponding to 0, 1, 6, 12, and 24% of PAC of each soil. In the soil, the mineralogy of the clay fraction (hematite, goethite, gibbsite and kaolinite) and crystallographic attributes were characterized. In the plant, we evaluated growth and pod production. The PAC of the soils ranged from 220 to 650 mg dm -3 with higher value in the RYL associated to clayey oxidic mineralogy and texture in relation to the TH of kaolinite origin and sandy texture, where the higher energy of adsorption observed was to TH. Phosphorus application from 16 to 21% of PAC, independently of the soil, promotes the same pattern of response with improvements in soybean development evidenced by increases in P content in plant tissue, plant height, root volume and aerial dry mass.
