Analysing the Drivers of Cropland Footprint in Leading Agricultural Nations: Evidence From MMQR Approach

Geological Journal, EarlyView.
ABSTRACT Climate change represents the biggest current challenge for us and for future generations. Its impact on agriculture is undeniable, considering the food security goal. Thus, the cropland footprint has been distinguished as a comprehensive index for assessing the impact of environmental changes in agricultural areas determined by the increased ...

Prediction of water retention of soils from the humid tropics by the nonparametric k-nearest neighbor approach [PDF]

, 2013
Nonparametric approaches such as the k-nearest neighbor (k-NN) approach are considered attractive for pedotransfer modeling in hydrology; however, they have not been applied to predict water retention of highly weathered soils in the humid tropics ...

Key soil health indicators under humid grazing lands

Grassland Research, EarlyView.
Soil health can be described using a few key soil health indicators that target a diversity of soil functions. This perspective article highlights how forage management affects these soil health indicators in humid‐zone grazing lands. Abstract Background Soil health describes critical soil functions influenced by land management. Although some key soil

Impacts of Biostimulants on Nitrous Oxide Emissions and the Soil Microbiome

Journal of Plant Nutrition and Soil Science, EarlyView.
Soil incubation experiment examining the influence of biostimulants on greenhouse gas emissions and the soil microbiome in fertilized soils. ABSTRACT Background Overapplication of nitrogenous fertilizer and enhanced microbial activity in agricultural soils are drivers of increasing greenhouse gas emissions.

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

Lethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Moessbauer Spectroscopy for Lunar Resource Assessment: Measurement of Mineralogy and Soil Maturity [PDF]

First-order assessment of lunar soil as a resource includes measurement of its mineralogy and maturity. Soils in which the mineral ilmenite is present in high concentrations are desirable feedstock for the production of oxygen at a lunar base.

Effects of Polyvalent Cations on FTIR Spectra of Organic Matter–Cation Associations

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background The composition of soil organic matter (SOM) can be characterized by functional groups in the organic matter (OM). The carboxylic acid and carboxylate groups of OM show specific absorption bands in Fourier‐transform infrared (FTIR) spectra. However, cation–OM interactions may affect absorption bands and limit spectral interpretation
