The main objective of this study was to evaluate the effectiveness of a soil conditioner derived from steel slag (Agrosilicio Plus – ASP) compared to dolomitic limestone (DLS) in agriculture. The research questions were about how ASP compares to DLS in terms of soil acidity correction, productivity, and the nutritional status of the forage grass Panicum maximum cv. BRS Zuri. Two experiments were conducted in a greenhouse using plastic pots filled with a 0-20 cm layer of Ferrasol. In the first experiment, soil conditioners were applied on the surface, while in the second, they were incorporated into the soil. A complete block design with a 2 × 4 + 1 factorial arrangement was employed. The factors included two soil conditioners (ASP and DLS) at four application rates (25%, 50%, 100%, and 150% of the liming requirement). A control treatment without any conditioner application was also included. P. maximum was grown in three successive 45-day cropping cycles. The shoot dry mass and nutrient content in plants’ tissues were measured. Both ASP and DLS were effective in correcting soil acidity. The ASP led to a higher silicon accumulation in the plants, whereas DLS resulted in higher calcium accumulation. Increasing rates of both conditioners generally had positive effects on most variables measured. When applied on the surface, ASP led to higher dry mass production accumulated in three crops. ASP is a viable alternative to limestone for correcting soil acidity and supplying essential nutrients and silicon to BRS Zuri grass. Additionally, ASP can effectively be applied on the soil surface.

Stratification and mixing patterns of a water body are influenced by the variability of atmospheric systems, which can also modify their biogeochemical properties. The primary goal of this study was to analyze the effect of atmospheric cold fronts (CFs) on thermal stratification and water quality parameters in 4 embayments of the Furnas Hydroelectric Reservoir (FHR) (southeastern Brazil), a warm monomictic water body. A secondary goal was to evaluate the implications of this effect on the aquaculture of Nile tilapia Oreochromis niloticus (L.) in net cages. A 2 yr dataset of meteorological and water quality parameters was used to compute heat flux balance components and buoyancy frequency. These parameters were used to evaluate the influence of CFs on FHR water column stability and water quality. It was observed that the passing of CFs increased net heat loss and wind velocity, resulting in a partial mixture of surface waters with deeper layers. These changes in the physical structure of the water column altered the diel cycle of water temperature, led to a slight decrease in dissolved oxygen concentrations and pH values during the stratification period, and contributed to the increase in dilution power at the fish cultivation sites. However, following CF passages, no significant changes were observed in water quality parameters that influenced Nile tilapia cultivation in the FHR. Nevertheless, the understanding of meteorological systems and their influence on the physical and biogeochemical properties of an aquatic system is important for optimal management of aquaculture activities.
