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 (

Recovery of aboveground biomass in Ohio, 1978

, 1982
Timber-use studies in Ohio show that multiproduct harvesting could be improved. The recovery rate from these operations, expressed as a ratio of the merchantable stem biomass estimate, is 103 percent. Although current methods of multiproduct harvesting have improved recovery of the merchantable stem, an estimated 1,539 thousand fresh tons of total ...

Nitrogen Fertilizer Application in Grass–Clover Elevated Nitrate Leaching in the Follow‐on Maize Crop

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Grass–clover and silage maize are key for dairy feed production and frequently occur within the same crop rotations. Fertilizer management in grass–clover may leave residual effects that influence both environmental outcomes and the performance of subsequent maize crops.

Dynamic Monitoring Method for Aboveground Biomass of Maize Based on Multi-source Data

应用气象学报
The aboveground biomass of maize is regarded as a crucial indicator for monitoring maize growth. However, it's challenging to meet the practical needs for dynamic remote sensing of aboveground biomass during early growth stages.

Intra‐Plant Nitrogen Isotope Fractionation in Maize

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background and aim The natural abundance of nitrogen isotopes (δ15N) provides a powerful integrative tracer of nitrogen uptake and assimilation in plants, yet the internal partitioning of δ15N among plant tissues remains insufficiently understood.

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 ...

Optimization of the National Biomass Allometric Equation Using Remote Sensing Data [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Accurately estimating forest aboveground biomass is crucial for assessing its carbon sequestration and carbon emission capacity. However, the traditional approach to estimating biomass is time-consuming and labour-intensive.

Loss of aboveground forest biomass and landscape biomass variability in Missouri, US

Ecological Complexity, 2016
Abstract Disturbance regimes and forests have changed over time in the eastern United States. We examined effects of historical disturbance (circa 1813 to 1850) compared to current disturbance (circa 2004 to 2008) on aboveground, live tree biomass (for trees with diameters ≥13 cm) and landscape variation of biomass in forests of the Ozarks and Plains

Field Simulation of Global Change: Transplanting Northern Bog Mesocosms Southward [PDF]

, 2010
A large proportion of northern peatlands consists of Sphagnum-dominated ombrotrophic bogs. In these bogs, peat mosses (Sphagnum) and vascular plants occur in an apparent stable equilibrium, thereby sustaining the carbon sink function of the bog ecosystem.
