Summary: Soil thermal properties are influenced by multi-species cover crops, and this study evaluated the effects of various cover crops on soil physical and thermal properties. The results showed that cover crops reduced bulk density and increased volumetric water content at different soil water pressures. The thermal conductivity was higher under no cover crop management, while the volumetric heat capacity was higher under cover crop management. Regression analysis revealed that plant roots and volumetric water content were the most important factors influencing thermal conductivity at different soil water pressures. In conclusion, no-till cover crops can improve soil thermal properties by moderating heat transfer.

Summary: The long-term effects of no-till management on soil-profile compactibility are still unknown. Previous studies have mainly focused on the upper soil depth, limiting the understanding of compactibility changes at deeper depths. This study investigates the Proctor bulk density, maximum bulk density (MaxBD), critical water content (CWC), and their relationships with soil organic C (SOC) and mean weight diameter (MWD) for different soil depths in long-term tillage experiments. The results show that no-till reduces compactibility only near the surface, while disking reduces compactibility to deeper depths, suggesting that disk tillage may be more effective than no-till in reducing soil compactibility.

Summary: This study compared the impact of no-till and conventional tillage practices on maize physiological parameters and evapotranspiration losses, finding that photosynthetic photon flux density played a crucial role in the variability of leaf stomatal resistance. The results showed that disk-till maize had higher leaf stomatal resistance compared to no-till maize at different growth stages. By developing response curves, valuable data for plant physiology research, crop modeling, and understanding crop responses to different management and environmental drivers were provided.

Summary: Research is needed to develop and optimize sustainable agroecological practices in agriculture. Field experiments were conducted in Maryland and New York to assess the effect of cover crop cultivar selection and termination soybean planting date on crop growth, biomass, weed biomass, and soybean yield. The results showed that earlier planting of soybean before cover crop anthesis can maximize yield. Farmers can improve management by selecting regionally adapted cultivars rather than focusing solely on biomass production.

Summary: Converting grassland to arable cropping can lead to decreased soil organic carbon (SOC) stocks, impacting soil and climate protection goals. However, using direct drilling in forage production systems like silage maize can prevent SOC stock degradation without reducing herbage yield. Long-term practices, such as a three-year grass phase followed by three years of silage maize, can help maintain SOC stocks.

Summary: One of the most common problems in maize production is the management of plant residues. Small agricultural enterprises face technical problems in preparing the sowing bed without proper machinery. This study compares the performance of no-till sowing machine prototype and stalk cutting machine prototype with the classical stalk cutter. The results show that the stubble cutting machine prototypes result in lower fuel consumption and penetration resistance compared to the classical stalk shredder.

Summary: The extent to which long-term application of mineral fertilizers regulates the quantity, quality, and stability of soil organic matter remains unclear. The study investigated the effects of 10-year fertilization on the molecular composition, decomposition, and origins of soil organic matter in a cropland in North China. Fertilization increased soil organic carbon in the mineral-associated organic matter fraction but had limited effect on bulk soil organic carbon levels, and altered the composition and origins of soil organic matter.

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.

Summary: This study investigates the structural strength of the Loess-Paleosol Sequence (LPS) and finds that the strength tends to increase with burial depth, with the loess layer weaker than the paleosol layer. 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.
