Metal–Phenolic Complexation Governs Soil Mineral Crystallinity to Enhance Crop Growth

Advanced Science, EarlyView.
A coordination‐driven, coprecipitation approach is presented to obtain polyphenolic‐incorporated minerals with tunable crystallinity, offering insights into how plants may influence soil mineral structures. Soil minerals can incorporate polyphenolic secondary metabolites and enhance plant nutrition by facilitating the formation of amorphous metal ...

Long-term optimization of saffron yield and economic water productivity as influenced by irrigation water depths, salinity levels, and planting techniques

Scientific Reports
Saffron (Crocus sativus L.) is one of the most valuable spice crops in the world, but its productivity is highly sensitive to water availability, soil salinity, and cultivation methods. In many arid and semi-arid regions, where saffron is typically grown,

Rhizodeposition Drives One Third of Belowground Carbon Input in Agroecosystems

Advanced Science, EarlyView.
This study quantifies photosynthesized C allocation in the plant–soil system across six crop types: barley, wheat, maize, rice, legumes and grasses. It reports C partitioning into shoot respiration, shoot‐C, root‐C, net rhizodeposition and root‐derived CO2, providing standardized percentage averages and GPP‐derived absolute values as a robust baseline ...

Soil pH Amelioration Synergizes Carbon Accrual with Yield Gains Under Organic Substitution

Advanced Science, EarlyView.
Soil pH shifts towards neutrality in both acidic and alkaline soils under organic substitution. A global synthesis links pH amelioration to soil organic carbon accrual through enhanced microbial biomass after accounting for added organic carbon and its interaction with pH. This pH amelioration‐shared soil organic carbon accrual accounts for 5.1–8.6% of
