“…The effects of the interaction of the quantity and quality of organic materials, the used species, and the climate conditions of the location are important for understanding the results in the process of recovering soil chemical properties [6,23]. In addition, the use of gypsum and alternative co-products is of paramount importance in soil recovery [2,9,24].…”

The investigation and application of recovery techniques associated with the use of qualitative and quantitative indicators enable the ecological restoration of these sites. In this context, the main difficulty consists of establishing the A horizon, capable of supporting the emergence of other horizons, choosing appropriate species, and adding organic matter to the soil in a balanced way. Thus, this study aimed to evaluate over time (1992 to 2022) the chemical properties of a stripped oxisol that has been in the recovery process for 30 years, using liming, gypsum, and plant species. All treatments were cultivated with Urochloa decumbens (Stapf.) in 1999 and tree species in 2010, and the contents of phosphorus, organic matter, pH, and base saturation. ANOVA and Scott–Knott test (5%), Pearson correlation, and response surface analysis were performed for each studied soil attribute. The results showed that the treatments with green manure + limestone + gypsum had the highest values of organic matter compared to the recovery treatments and that the treatments have been efficient in soil recovery. Therefore, the soil undergoing recovery showed an increase in P, OM, pH, and base saturation until 2011, and the response surface method was the most efficient in analyzing the results over time.

Salinity is a process that directly interferes with soil and water quality, compromising agricultural crops. The objective of this study was to evaluate the influence of biostimulant application in mitigating the toxic effects of experimental salt concentrations on watermelon seedlings. Seedling production was carried out using seeds of the watermelon cultivar ‘Crimson sweet’, and the tested treatments were distributed in a 3x2 factorial arrangement. The first factor consisted of three levels of soil salinity with electrical conductivities: 0.6; 2.6; 4.6 dS m-1. The second factor consisted of the presence or absence of biostimulant application. Sowing was carried out in polypropylene containers with a capacity of 300 dm3. Two seeds were sown, and the plants were thinned to one plant per container five days after emergence. Foliar applications of the biostimulant were carried out 7 and 14 days after emergence at a level of 300 mL ha-1. The experimental design was randomized blocks (RBD) with four replications. Watermelon seedlings exposed to salinities ranging from 0.6 to 4.6 dS m-1 showed limited growth and development, evidencing the toxic and harmful effects of salinity on the plants tested during the seedling stage. The biostimulant at the recommended level of 300 mL ha-1 did not show results that could verify the mitigation of substrate salinity or increased growth and development of watermelon seedlings.
