Summary: The study found that different cover crops have varying effects on soil microbial activity, with sorghum crops producing higher aboveground biomass and microbial biomass carbon in the soil while reducing microbial activity. The differentiation in bacterial community structure was mainly observed in soils cultivated with sorghum, Pennisetum americanum, and Crotalaria ochroleuca.

Summary: This study investigated four deep, well-developed soils along a basalt-sandstone transition, revealing the influence of soil parent material on their genesis, chemical and mineralogical composition. Basalt soils were characterized by high clay contents and specific mineral components, while the sandstone soil had lower clay content and different mineral composition. The different soil types along the toposequence exhibited varying fertility levels and unique characteristics, likely influenced by the formation of an interstratified clay mineral complex.

Summary: No-till (NT) as a conservation practice aims to minimize soil disturbance and enhance soil sustainability. This study assesses the effect of NT on soil physicochemical and biological properties in soybean areas in Brazil, and finds that NT can enhance soil fertility and biological quality, leading to increased soybean productivity without the need to increase the sown area. The study also highlights the importance of adopting NT practice for sustainable agriculture.

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: This research studied the soils of four citrus orchards in western Zhejiang and conducted an incubation experiment to explore the effects of lime on soil chemical properties and bacterial communities. The results showed that lime application increased soil pH initially, but reacidification occurred over time. Lime addition increased the nitrate nitrogen content and decreased the ammonium nitrogen content in the soils. Furthermore, appropriate lime addition improved soil integrated fertility index and bacterial community diversity and stability.

Summary: The intensification of agricultural systems, such as vegetable production, to meet the global food demand has led to increased soil compaction and changes in soil physical properties. This study investigated the effects of vegetable cropping systems on highly weathered Oxisols in the Brazilian Cerrado biome. The results showed that these systems promoted soil compaction, reduced soil porosity, and negatively impacted soil functions and ecosystem services. Improving soil management strategies is crucial for restoring soil functionality and ensuring the long-term sustainability of food production.

Summary: This study evaluated the energy fluxes and decoupling factor in pasture lands in the Brazilian Cerrado. The results showed that latent heat flux predominated during the wet season, while the ratio of latent heat flux to net radiation decreased during the dry season. The study also found that pasture lands were highly coupled to the atmosphere during the dry season, and the observed surface decoupling factor was lower in 2017-2018 due to the control of stomatal conductance during the unexpected drought.

Summary: The study revealed that soil copper and zinc concentrations increased after pig slurry and deep-litter applications, with copper accumulating mainly in organic and residual fractions, while zinc accumulated more in mineral and exchangeable fractions. Additionally, the higher organic matter content in deep-litter could lead to greater adsorption of copper and zinc in the soil.

Summary: Copper can be toxic to vegetables and poses a risk to the human food chain. This study determines the critical concentrations of copper that are toxic to beet and cabbage plants and their potential to enter the human food chain. Additionally, the physiological and biochemical responses of these plants to increasing copper concentrations were assessed. High copper concentrations inhibit plant growth and pose a potential threat to the human food supply.

Summary: Copper (Cu)-based fungicide application can increase soil Cu availability, but this can be problematic in soils with high natural Cu and manganese (Mn) concentrations, such as Brazilian soils. Applying amendment substances, like limestone, can reduce the toxic species of Cu and Mn in soil solution, leading to improved grapevine growth. In this study, vermicompost application did not alleviate Cu and Mn phytotoxicity, while limestone application significantly increased grapevine shoot and root dry matter production.

Summary: The use of organic wastes and fertilizers can increase crop productivity, but it can also lead to the accumulation of copper and zinc, posing risks to plants and the environment. This study found that the application of pig manure increased the availability of copper and zinc in the soil, but did not negatively impact crop productivity, instead leading to increased dry mass production and crop yield.

Summary: This study compares three different potassium (K) fertilizer rate recommendation ideologies in terms of profitability, yield, and fertilizer use. The results show that K use equilibrates over a 3-year period regardless of the starting soil-test K (STK) level, and considering long-run STK implications has minimal effect on yield. Therefore, the study encourages producers to use annual profit-maximizing K rates, which are 3-11% lower than the existing recommendations (KE), as they generate more profit with minimal yield loss.

Summary: This study evaluated the effects of long-term winter cover crops under conventional farming system and no-tillage system on edaphic fauna in a Rhodic Hapludox soil in Parana State, Brazil. Three winter cover crops and a fragment of natural forest were used. Soil monoliths were collected at two different times and the density of edaphic fauna was measured. Results showed that the density of edaphic fauna was inversely related to soil depth. The use of winter cover crops with no-tillage system resulted in higher densities of fauna compared to the conventional farming system.

Summary: The terms "base saturation", "exchangeable bases", and "basic cations" used in Soil Science are not accurate in distinguishing different cations and can lead to confusion and misinterpretation. The most appropriate term should be Ca-Mg-K-Na saturation, rather than the current terminology. When calculating base saturation, it is sufficient to consider the sum of Ca, Mg, and K, as the Na content is usually negligible in tropical and subtropical soils. It is also suggested to abolish the use of the term "sum of bases" and instead use "sum of Ca-Mg-K" or "sum of Ca-Mg-K-Na" when necessary.

Summary: This study investigates the effects of erosion degradation and long-term manure fertilization on soil properties and crop yield in Northeast China. Results show that erosion degradation and manure fertilization have lasting impacts on soil physical structure throughout the soil profile, while their effects on soil nutrient properties are focused in shallow layers. Manure fertilization significantly improves soil functional index (ISI) and maize yield for degraded soils. Erosion degradation has a greater influence on ISI and maize yield than manure fertilization.

The microstructure of the LPS also undergoes significant transformations with increased burial depth, transitioning from an overhead structure to a matrix structure. These findings highlight the importance of climate conditions on the structural strength of the LPS.

Summary: This study aimed to evaluate the impact of long-term nutrient management practices on P fractions and P adsorption-desorption behaviour of an acid soil with a soybean-wheat cropping system. The findings revealed that amorphous Fe and Al, which play a significant role in P fixation, increased due to cultivation. The NPK+Lime treatment offered the most balanced approach, improving both crop yield and P uptake while effectively managing P dynamics in the soil. On the contrary, long-term application of NPK+FYM in an acid soil may result in faster P saturation of adsorption sites and increase the chances of leaching and eutrophication. Tailored P fertilization strategies should be developed to better utilize the PFe and PAl fractions and supplementing applied P.
