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

Grassland 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 ...

Climate Warming Consistently Reduces Grassland Ecosystem Productivity

Earth's Future, 2021
Future climate may profoundly impact the functioning of terrestrial ecosystems. However, we do not know well how the functioning of different types of grassland ecosystems is associated with variation in temperature and precipitation.

A Coupled AquaCrop–Richards Model for Improved Crop Yield Prediction Through Physically Based Soil Water Dynamics

Irrigation and Drainage, EarlyView.
ABSTRACT Crop modelling is essential for agricultural water management but often relies on simplified water balance routines that limit representation of soil moisture dynamics. To address this limitation, we developed a coupled model that integrates the 1‐D Richards equation, solved using a finite difference method into the FAO AquaCrop.

Maize Yield, Water Productivity and Economic Analysis Under Different Irrigation and Nitrogen Management Strategies Using Field Data and CERES‐Maize Model

Irrigation and Drainage, EarlyView.
ABSTRACT There is limited integrated evaluation of nitrogen (N) and irrigation management strategies for improving maize yield and productivity using crop models. The effects of N and irrigation on maize yield and productivity under centre pivot (CPI) and subsurface drip irrigation (SDI) using the CERES‐Maize model were investigated. N treatments were (

An evaluation model for aboveground biomass based on hyperspectral data from field and TM8 in Khorchin grassland, China.

PLoS ONE, 2020
Biomass is an important indicator for monitoring vegetation degradation and productivity. This study tests the applicability of Hyperspectral Remote-Sensing in situ measurements for high-precision estimation aboveground biomass (AGB) on regional scales ...

Aboveground Net Primary Production at Acacia mangium Plantation in Northern Vietnam

Asian Journal of Research in Agriculture and Forestry, 2019
Net primary production (NPP) is an important index for understanding carbon cycling in forest ecosystems. In this study, aboveground NPP at Acacia mangium plantation was estimated basing on allometry for aboveground biomass increment (ΔM) and litter trap technique for litterfall (Lf). The experiment was conducted in two plots of 300 m2 each (15 × 20 m),

Effects of Crop Rotation and Hydrogel Application on Soil Biological Properties and Wheat Biomass Production in Drylands

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background and aim Conservation agriculture (CA) is rapidly gaining traction to promote sustainable crop production, focusing on minimum soil disturbance, permanent soil cover, and strategic crop rotation. Moreover, hydrogel is increasingly being used to improve water retention, including in combination with CA, particularly in water limited ...

Inorganic nitrogen supply and dissolved organic nitrogen abundance across the US Great Plains.

PLoS ONE, 2014
Across US Great Plains grasslands, a gradient of increasing mean annual precipitation from west to east corresponds to increasing aboveground net primary productivity (ANPP) and increasing N-limitation.

Aboveground biomass and seasonal patterns of aboveground net primary productivity in five bamboo species in northern Laos

Journal of Plant Ecology, 2019
Abstract Aims Accurate estimates of bamboo biomass and net primary productivity (NPP) are required to evaluate the carbon sequestration potential of bamboo forests. However, relevant data that are important for climate change mitigation, have rarely been collected in regions outside of East Asia and ...
