Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant‐ and microbial‐derived residues constitute the primary sources of soil organic carbon (SOC) in grassland ecosystems. However, their differential responses to chronic nitrogen (N) enrichment and the depth‐dependent mechanisms governing their accumulation remain ...

Shrub encroachment influences root traits and mycorrhization in subalpine grasslands
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Shrub encroachment into grasslands modifies ecosystem functions, species composition and soil properties. However, knowledge about its detailed below‐ground effects and specifically on concurrent changes in root traits and mycorrhizal associations is missing. We studied

Using [delta] ph as a geochemical index of illite neoformation in saprolite [PDF]
, 2008 Sal pH is routinely measured for agronomic purposes. When the difference between KCI pH and H2O pH, or ApH, yields positive values, it is used by soil scientists as a classification criterion for identifying anionic subgroups according to the Soil ...

Australian Journal of Agricultural and Resource Economics, EarlyView.ABSTRACT This study examines the factors influencing producer adoption of cover cropping and no‐till farming, two key carbon sequestration practices, within the context of voluntary carbon credit programmes (CCPs) in Kansas. Using a mixed‐methods survey that combines discrete choice experiments with farm‐level data from 370 producers, we estimate ...

AGROECOLOGY AND CLIMATE CHANGE IN THE SEMIARID TROPICS
Redes, 2017 This article makes a theoretical and, to a certain extent, propositional reflection on the conceptions, assumptions and evidences of climate change in the tropics, with emphasis on the Brazilian semiarid region. The contributions of agriculture to climate change are presented and the impacts of climate change on family agriculture in the semiarid ...
