Sources of nitrogen for winter wheat in organic cropping systems [PDF]
, 2013 In organic cropping systems, legumes, cover crops, residue incorporation, and manure application are used to maintain soil fertility, but the contributions of these management practices to soil nitrogen (N) supply remain obscure.

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite
Advanced Functional Materials, EarlyView.The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Advanced Functional Materials, EarlyView.A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,

Tracking Battery Microstructural Degradation Through Directional Thermal Transport Signatures
Advanced Functional Materials, EarlyView.In lithium‐ion batteries, heat conduction varies between the through‐plane and in‐plane directions because of the cell's layered structure. Therefore, cell degradation influences thermal conductivity in each direction uniquely due to detailed microstructural and compositional changes.

Pennycress as a Cash Cover-Crop: Improving the Sustainability of Sweet Corn Production Systems
Agronomy, 2020 Commercial sweet corn (Zea mays convar. saccharata var. rugosa) production has a proportionally high potential for nutrient loss to waterways, due to its high nitrogen (N) requirements and low N use efficiency.

Impacts and fate of experimentally enhanced nitrogen deposition on a British lowland heath
, 1998 Between 1989 and 1996, nitrogen, in the form of (NH4)2SO4 (7.7 or 15.4 kg ha-1 year-1), was added to experimental plots of Calluna at a lowland dry heath in the south of England. Background deposition at this site was estimated at between 13-18 kg N ha-1

Effect of Nitrogen Management on Yield and Eating Quality of Rice
Liang you shipin ke-jiNitrogen management plays a crucial regulatory role in ensuring rice yield and improving eating quality. In recent years, the significant increase in rice yield has largely relied on the excessive application of nitrogen fertilizers. However, the overuse
