Simulating Tillage Effects on Nonpoint Source Pollution from Agricultural Lands Using GLEAMS [PDF]

, 2001
A GLEAMS (ver. 2.10) model was calibrated and validated using three years (1990–1992) of field–measured data to simulate tillage effects on nitrate–nitrogen (NO3–N) and herbicide losses with subsurface drain “tile” water beneath a continuous corn ...

Soluble organic nitrogen in potentially mineralizable N assays: are we missing an important component? [PDF]

Canadian Journal of Soil Science, 2018
We examined soluble organic nitrogen (SON) leached from long-term, sequentially leached, aerobic incubations. Leached SON, present in all depths (0–60 cm), ranged from 35% to 56% of total nitrogen (N). This unaccounted-for SON may have important implications in the estimation of plant available N and the potential for environmental N losses.

Impact of Sugarcane Management Practices and Time Periods on Soil Organic Carbon and δ13C Signature After Paddy Rice Conversion

Land Degradation &Development, EarlyView.
ABSTRACT Land use change (LUC) from paddy rice to sugarcane cultivation strongly influences soil organic carbon (SOC) stocks, with the extent and direction of change depending on residue management and time since conversion. This study aimed to (i) evaluate SOC stock changes under different residue management practices and conversion periods following ...

Minimal soil disturbance and increased residue retention increase soil carbon in rice - based cropping systems on the Eastern Gangetic Plain [PDF]

, 2018
The adoption of conservation agriculture (CA) in the intensive triple-cropping, rice-based systems of the Eastern Gangetic Plain (EGP) alters the dynamics of carbon (C) in the soil, but the nature of these changes is poorly understood.

Which indicators are most effective at detecting rapid shifts in soil health?

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract Farmers are showing a growing interest in soil health. Therefore, it is necessary to understand how and when indicators respond to changes in land management. Measurements of soil carbon (C) and nitrogen can take up to a decade to shift. However, it is unknown how other biotic markers of soil health (i.e., nematode communities) react.

Estimation of N2O emission factors for soils depending on environmental conditions and crop management [PDF]

, 2009
Nitrous oxide (N2O) contributes 8% to anthropogenic global warming, of which about one third are direct emissions of agricultural soils. These N2O emissions are often estimated using the default IPCC 2006 emission factor of 1% of the amount of N applied ...

Growth, Development, and Nitrogen Uptake of Fodder Beet (Beta vulgaris L.) Crops Grown Under Differing Rates and Timing of Nitrogen Fertiliser in New Zealand

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
Fodder beet (Beta vulgaris L.) is an important forage crop used for cattle wintering in New Zealand. Regional nitrogen (N) fertiliser experiments over two seasons (2016–2018) consisting of different N application rates (0–300 kg N/ha) and times of N application (sowing, canopy closure, and mid‐bulb development stage) were used to validate yield ...

Plant and Soil Function Increase With Larger and Older Coarse Woody Debris

Global Ecology and Biogeography, Volume 35, Issue 3, March 2026.
ABSTRACT Aim Coarse woody debris is increasingly being used in ecological restoration. We aimed to assess the global impacts of woody debris on ecosystem properties and functions. Location Global. Major Taxa Studied Soil biota, plants, soil function. Methods We conducted a quantitative global meta‐analysis of 66 studies (5234 observations) to assess ...
