A new study published in Nature Geoscience reveals that China's cropland soils have stabilized in pH levels since 2013, linked to agricultural policy reforms. However, recovery has been slow and uneven across different types of farmland, with paddy fields showing signs of improvement but dryland soils remaining acidic.
A new study reveals the first detailed structure of HvAACT1, a barley root protein that enables plants to tolerate aluminum-rich acidic soils. This breakthrough provides the structural basis for citrate efflux in plants and has implications for designing crops that can withstand difficult conditions.
Researchers found that changes in pH levels result in three distinct metabolic states of the community, driven by indigenous biomass activity and nutrient availability. The simple model predicts the activity with just two parameters, offering insights into how soil microbiomes adapt to climate change.
A recent study published in Science reveals a vast store of global soil inorganic carbon (SIC) amounting to 2,305 billion tons, surpassing vegetation's combined carbon content. This 'hidden pool' is vulnerable to environmental changes, posing significant risks to ecosystem functions and climate change mitigation strategies.
New research reveals that nitrogen released by gas-powered machines causes dry soil to let go of carbon and release it back into the atmosphere. The study found that excess nitrogen acidifies soils, leading to a loss of carbon stored in association with calcium.
University of Adelaide scientists developed a new simple and inexpensive method to detect low concentrations of agricultural lime in soils. The Mid Infrared spectroscopy technique allows for accurate detection of very small amounts of lime, enabling farmers to manage their soils more effectively.
The study reveals that increases in soil biodiversity follow plant cover increases in less productive ecosystems, while acidification leads to declines in more productive ecosystems. These patterns differ from those observed in other communities.
Australian and Chinese researchers have made significant progress in determining the causes of soil acidification. By examining a massive transect of land in China, they found different drivers of soil acidification processes in various types of soils.
Researchers found that soil pH, iron concentrations, and total cadmium levels are excellent predictors of biologically available cadmium for plants. Increasing soil acidity can also release more cadmium into the soil, while iron oxides bind it tightly.
Research shows that organic soils continue to acidify, posing a threat to forest health in the northeastern US. Despite declines in acidic deposition, soil base cation pools are insufficient to neutralize acidic inputs, leading to continued chemical recovery delays and increased vulnerability to winter injury.
A new study published in Nature Geoscience reveals the devastating impact of increased nitrogen deposition on Slovakian soil acidity, compromising plant fertility and surface water quality. Researchers warn that many soils are already susceptible to this process due to decades of human-influenced pollution.
