Summary: This study investigates the impact of silt and clay fractions on stabilizing organic carbon and total nitrogen in soils of old cultivated fruit orchards in Sohag, Egypt. The results show that silt and clay contribute significantly to the soil's cation exchange capacity and the content of organic carbon and total nitrogen. The presence of specific mineralogy, such as phyllosilicates, in the fine fractions also has a positive effect on the soil's sequestration of organic carbon and total nitrogen.

Summary: Soil organic matter (SOM), storing carbon (C) and essential plant nutrients in the soil for thousands of years, has been recognized by scientists for its positive impact on vital environmental functions like food production and climate regulation. However, when virgin land (forests or grasslands) is converted to agriculture, the soil tends to lose its SOM, and the lack of understanding of the underlying mechanisms has led to inappropriate interventions to combat soil, climate, and ecosystem deterioration.

Summary: The availability of nitrogen (N) has been found to influence the mineralization of soil organic carbon (C), but its effect on the decomposition of native soil organic C induced by labile C input (i.e., priming effect) remains unclear. This study investigated the impact of N supply rates on the magnitude and direction of the priming effect, and how this interacted with soil layers differing in organic C content. The results showed that N addition increased the priming effect up to a certain level, and this effect was greater in the surface layer of topsoil compared to the subsurface layer. These findings highlight the susceptibility of soil organic C to loss through N-enhanced priming.

Summary: Straw return is a recommended practice to improve soil fertility, but it often leads to increased methane emissions from rice paddies. This study investigated how the tillage type (before or after irrigation) affects methane emission under straw return. The results showed that dry tillage before irrigation mitigates methane emission, while wet tillage after irrigation reduces methane emission in the absence of significant interaction between straw and tillage type.

Summary: Crop breeding has successfully increased crop grain yield through reduced vegetative size, increased reproductive effort, and improved water-use efficiency. The relationship between grain yield and time from sowing to flowering remains unclear. Early flowering genotypes have higher water-use efficiency in grain production, but no significant difference in total biomass production. Yield is positively correlated with soil water remaining at harvest. Further increases in grain yield through this route are unlikely in the future.

Summary: No-tillage with straw mulch is effective for soil sustainability, but its specific effects on soil organic carbon stocks and crop yield are uncertain. This study found that no tillage had minimal effects on soil organic carbon stocks but decreased crop yield compared to plow tillage with straw return. No-tillage with straw mulch resulted in improved soil aggregate stability and organic carbon content in the 0-5 cm layer, but decreased organic carbon content in the deeper layers due to reduced carbon input from roots and straw. While organic carbon stocks in micro-aggregates and mineral-associated organic matter did not vary between tillage practices, plow tillage with straw return had higher organic carbon stocks in the 0-50 cm layer compared to no-tillage with straw mulch. Additionally, the yields of rice and wheat were lower under no-tillage with straw mulch compared to plow tillage without straw return and plow tillage with straw return, attributed to high soil bulk densities and decreased nutrient availability. The yield losses in rice were greater under no-tillage with straw mulch and increased over time due to decreased nitrogen and phosphorus contents in the soil. In conclusion, plow tillage is more effective for carbon sequestration and yield improvement in rice-wheat farming compared to no-tillage with straw mulch.

Summary: Plants can modulate their phosphorus acquisition strategies to adapt to varying soil phosphorus availability. When soil phosphorus is low, nitrogen addition increases the release of carboxylates from plant roots and leads to a higher percentage of colonization by arbuscular mycorrhizal fungi (AMF), along with decreased root length and specific root length (SRL). When soil phosphorus is higher, nitrogen addition increases the plant's demand for phosphorus, accompanied by an increase in root diameter and phosphatase activity.

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.
