Summary: Soil acidity remains a limiting factor for crop yield in tropical soils. Incorporating lime into the 0-40 cm depth significantly improves soil chemical conditions, root growth, and crop yield. Lime rates of 9-15 Mg ha-1 have the highest positive impact, increasing Ca2+ and Mg2+ contents, pH, and base saturation. Deep liming at the correct dose enhances the resilience of agricultural systems to water deficit and improves the yield potential of annual crops in highly weathered tropical soils.

Summary: This study evaluated the radiation shielding properties of different soils and found that soils with higher densities had better shielding capabilities. The increase in clay, Fe2O3, Al2O3, and TiO2 content in the soils was associated with higher attenuation coefficients and lower shielding parameters.

Summary: The influence of long-term chemical fertilization in paddy soils on SOC is attributed to the interaction between labile carbon and phosphorus fractions. In the 0-5 cm soil layer, easily oxidized organic carbon components and other soil physicochemical characteristics have a stronger interaction with SOC. An increase in DOC in this layer significantly lowers SOC, which is positively correlated with POXC but negatively correlated with SOC and WSC. The changes in SOC can be explained by the relationship between DOC and inorganic phosphate fractions under specific soil pH conditions.

Summary: This study selected 41 pedons from weathered clastic sedimentary rocks to evaluate the uniformity of parent material and soil profiles. The results can be helpful in distinguishing argillic horizons and identifying differences among different soil profiles in quantitative soil classification. Various analyses, such as Ti/Zr ratio, particle size distribution, morphological characteristics, physical and chemical properties, and geochemical element characteristics, were conducted to quantitatively assess the uniformity of parent material and soil profiles. The coefficient of variation (CV) of soil properties was used as an input variable for the random forest model to assess soil profile uniformity. The results showed that the parent materials exhibited uniformity in terms of geochemical elements, but there were discontinuities in particle size caused by different surface erosion forces. In addition, color differences and sudden changes in generalizable horizon development indices were observed in some profiles. The physical and chemical properties, as well as geochemical elements, varied greatly due to complex sedimentary rocks and different terrain conditions, resulting in inhomogeneous soil profiles. Pedogenesis, slope deposit, and soil forming processes played a role in achieving soil profile uniformity. The random forest model showed that the CV of clay-free particle size distribution was the best input variable, and the CVs of Al, Si/Al ratio, clay, total phosphorus, and Na were convenient input variables for assessing soil profile uniformity.

Summary: The study examined the impact of soil texture and degree of compactness on total porosity and distribution of macro-, meso- and micropores. It found that total porosity and macroporosity are dependent on compactness and silt plus clay content, while meso- and micropores are mainly affected by particle size distribution. The findings suggest that increasing compactness may reduce total porosity and macroporosity, with meso- and micropores being more sensitive to changes in particle size distribution.

Summary: The availability of phosphorus in soils is influenced by factors such as mineralogy, acidity, and concentration of elements in the soil solution. The use of different phosphate sources and amounts can affect the adsorption process of phosphorus in the soil. A field experiment was conducted to examine the effects of different phosphate sources and doses on soil phosphorus fractions. The results showed that the application of different phosphates did not significantly affect the concentrations of soil phosphorus fractions over a 5 year study period. However, higher doses of phosphate fertilizer increased moderately labile and non-labile phosphorus fractions.

Summary: There is a growing societal demand to increase the use of forest biomass for substitution of fossil fuels, but the Critical Biomass Harvesting (CBH) indicator is criticized for not accounting for all relevant processes and exaggerating sensitivity, correlating poorly to actual forest soil conditions. It is suggested that the risk assessment and policy implications for forest biomass harvesting guidelines need to be based on solid scientific methods and data availability may not allow the indicator to be calculated at a high enough spatial resolution for forest management advice.

Summary: The fast weathering and intensive agricultural practices in tropical areas have led to the degradation of soil fertility. Biochar has been found to be an effective soil amendment for improving crop productivity in highly weathered tropical soils. However, further development is needed to reduce the production and application costs of biochar, and policy decisions are necessary to link economic benefits with social and environmental issues.

Summary: This study aims to investigate the potential of alternative phosphorus sources to improve phosphorus efficiency in weathered tropical soils of the Brazilian Cerrado region. The results indicate that precipitated phosphorus exhibited similar or better behavior in terms of availability and diffusion than triple superphosphate. Soil chemical properties also influence phosphorus fractions in weathering tropical soils. Therefore, precipitated phosphorus source is a promising alternative that could potentially improve phosphorus efficiency in these soils.

Summary: Currently, there are no resistant sweet orange cultivars to citrus canker. Transgenic plants expressing antimicrobial peptides and resistance genes from tolerant cultivars were evaluated for resistance to Xanthomonas citri subsp. citri (Xcc). Transgenic plants showed reduced incidence and severity of citrus canker, as well as lower Xcc titers. Higher superoxide dismutase activity in transgenic plants led to increased hydrogen peroxide production. Callose deposition, an important plant defense response, was observed in transgenic plants with lower Xcc populations.

Summary: The bioconversion of red tilapia by-products into protein hydrolysates using neutrase and papain resulted in a high degree of hydrolysis and yield. These tilapia protein hydrolysates (TPH) are rich in minerals, essential amino acids, and low-molecular-weight peptides. TPH exhibit water solubility and emulsifying capacity under neutral and alkaline conditions, but have low foam stability. TPH also demonstrate strong antioxidant activity and promote bacterial growth. Therefore, TPH offer potential as functional and bioactive ingredients in food formulations, a high-performance bacterial culture media, and a sustainable solution for reducing tilapia-processing wastes.
