Revolutionising Agricultural Sustainability: New ‘Furrow Tillage’ can Mitigate Short‐Term Soil‐to‐Atmosphere CO2 Flux and Promote Soil‐Plant‐Microbe Health

open access: yesAdvanced Science, EarlyView.
Furrow tillage resolves the conventional‐vs.‐no‐tillage trade‐off by simultaneously cutting CO2 efflux to 2.0–3.0 g C m−2 d−1 and unlocking high nutrient availability for the rice rhizosphere. This scalable agronomic solution strengthens soil health, enhances plant physiology, reshapes microbial metabolism, and shifts paddy systems toward a net ...

The effect of pruning on photosynthetic rate of cacao tree in a novel cropping system [PDF]

open access: yes, 2017
An intensive growing system requires regular pruning to maintain canopy architecture. More frequent pruning times on cacao plantations have been recommended to increase the productivity. However, limited studies have examined this topic in cacao. In this

Evolution in the photosynthetic oxygen rate of a Cd-resistant strain of Dictyosphaerium chlorelloides by changes in light intensity and temperature

open access: yes, 2020
Environmental factors such as temperature and light are the most determinants in the photosynthetic productivity in microalgae. However, under extreme of these conditions, certain resistant microalgae strains possess additional abilities such as growth ...

Hydrogen‐Bonding‐Directed Assembly of COF/Nanocluster Hybrids With Synergistic Roles for Efficient Solar Hydrogen Production

open access: yesAdvanced Science, EarlyView.
Hydrogen‐bonding‐directed assembly enables molecular‐level integration of a covalent organic framework and NiZnCo nanoclusters. The engineered interface couples directional charge transfer, multimetal synergy, and photothermal‐assisted catalysis, providing a versatile strategy for efficient noble‐metal‐free solar hydrogen production.
