Synergies and trade‐offs between ecosystem services and economics in dryland cover crop systems

open access: yesEcosphere
Replacing bare fallow periods with cover crops in dryland agroecosystems can help reverse soil degradation and control erosion but may also result in cash crop yield penalties due to water limitations.

Derivation of supply curves for catchment water effluents meeting specific salinity concentration targets in 2050: linking farm and catchment level models or “Footprints on future salt / water planes” [PDF]

open access: yes
The salt burden in a stream reflects the blend of salty and fresh flows from different soil areas in its catchment. Depending not only on long-run rainfall, water yields from a soil are also determined by land cover: lowest if the area is forested and ...

Long-term no-till: A major driver of fungal communities in dryland wheat cropping systems.

open access: yesPLoS ONE, 2017
In the dryland Pacific Northwest wheat cropping systems, no-till is becoming more prevalent as a way to reduce soil erosion and fuel inputs. Tillage can have a profound effect on microbial communities and soilborne fungal pathogens, such as Rhizoctonia ...

The economic cost of weeds in dryland cotton production systems of Australia [PDF]

open access: yes
Economic losses and costs associated with weeds in dryland cotton production are important, both for growers and for industry bodies when making decisions about research priorities and research and development funding.

Simulating climate change and land use effects on soil nitrous oxide emissions in Mediterranean conditions using the Daycent model [PDF]

open access: yes, 2017
In Mediterranean agroecosystems, limited information exists about possible impacts of climate change on soil N2O emissions under different land uses. This paper presents a modelling study with a dual objective.

Improving dryland cropping system nitrogen balance with no‐tillage and nitrogen fertilization

open access: yesJournal of Plant Nutrition and Soil Science, 2018
AbstractStudies on N balance due to N inputs and outputs and soil N retention to measure cropping system performance and environmental sustainability are limited due to the complexity of measurements of some parameters. We measured N balance based on N inputs and outputs and soil N retention under dryland agroecosystem affected by cropping system and N

Agro-Ecological Class Stability Decreases in Response to Climate Change Projections for the Pacific Northwest, USA

open access: yesFrontiers in Ecology and Evolution, 2017
Climate change will impact bioclimatic drivers that regulate the geospatial distribution of dryland agro-ecological classes (AECs). Characterizing the geospatial relationship between present AECs and their bioclimatic controls will provide insights into ...

ECONOMIC AND HYDROLOGIC IMPLICATIONS OF SUSPENDING IRRIGATION IN DRY YEARS [PDF]

open access: yes
A dry year irrigation suspension has been proposed as a way of reallocating water when aquifer levels are low for the Texas Edwards Aquifer. Under this program, farmers would be paid to suspend irrigation to allow more spring flow or nonagricultural ...

Crop and soil organic matter simulation models – A brief review of their basic features and application in sub-Saharan Africa [PDF]

open access: yes, 2020
Over the past decades, numerous crop-soil models have been developed to represent dynamic processes in cropland systems, including soil organic carbon (SOC) dynamics (Campbell and Paustian, 2015).
