Optimization of moisture content and application rate of hay preservative during high‐moisture alfalfa hay baling in northwestern China

open access: yesGrassland Research, EarlyView.
Abstract Background Leaf shatter during low‐moisture baling and mold proliferation under high‐moisture conditions pose major challenges in alfalfa hay production. A proprietary propionic acid‐based hay preservative product, LZP, effectively inhibits microbial reproduction in high‐moisture alfalfa bales; however, its optimal moisture thresholds and ...

Disturbance from restoration reseeding is associated with short‐term topsoil carbon loss and alters soil bacterial communities and functions in degraded alpine meadows of the Qinghai–Xizang Plateau

open access: yesGrassland Research, EarlyView.
Restoration reseeding of degraded alpine meadows increased aboveground vegetation but was associated with short‐term topsoil carbon loss, coinciding with a microbial strategy shift from resident carbon‐preserving to carbon‐spending bacterial guilds. Abstract Background Restoration of degraded ecosystems is widely promoted as a nature‐based solution ...

Simultaneous 3/4‐power scaling of leaf mass and 2/3‐power scaling of leaf area with stem mass in plants

open access: yesGrassland Research, EarlyView.
Abstract Background Plant allometry theory developed in the last century focused on 2/3‐power scaling, determined by light interception considerations. More recently, 3/4‐power scaling based on the properties of vascular distribution networks has been proposed.
