Digital soil mapping and GlobalSoilMap. Main advances and ways forward
(Elsevier, 2020)
In this concluding paper, we summarize the main advances coming forward from the joint conference of the International Union of Soil Sciences (IUSS) Working Groups (WG) "Digital Soil mapping" (DSM) and "GlobalSoilMap". We ...
Rainfall, microhabitat, and small mammals influence the abundance and distribution of soil microorganisms in a Chilean semi-arid shrubland
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2016)
Patterns in rainfall and soil water availability are considered to be the main drivers governing arid and semiarid ecosystems. While the mechanisms by which water limits aboveground net primary production has been widely ...
Decomposition of 14C-labeled lignins, model humic acid polymers, and fungal melanins in allophanic soils
(1982)
During 1 yr, CO2-C losses from 7 agricultural soils containing 0.5-1.5% organic C ranged from 70 to 243 mg 100 g - 1 while losses from three allophanic soils containing 4.9-8.9% organic C varied from 92 to 191 mg. Losses ...
Metal-binding organic macromolecules in soil: 2. characterization of the maximum binding ability of the macromolecules
(1977)
An experimental technique was devised to measure the maximum binding ability (MBA) of any macromolecule having electron donor groups. It is a dialysis technique wherein polymer portions are isolated in dialysis bags and ...
Potential of hydroxamic acids in breeding for aphid resistance in wheat
(1993)
Swedish wheats were analysed at the seedling stage for hydroxamic acids (Hx), a family of natural aphid resistance factors. Analysis comprised the historical development from old landraces to modem cultivars, and included ...
Decomposition of 14C-labeled glucose, plant and microbial products and phenols in volcanic ash-derived soils of chile
(1982)
During 4 months from 70 to 79% of the carbon of added glucose, cellulose, and Leuconostoc dextranicus polysaccharide had evolved as CO2 from normal agricultural soils of Chile and California. The presence or additions of ...
Degradation kinetics of chlorpyrifos and diazinon in volcanic and non-volcanic soils: influence of cyclodextrins
(Springer Verlag, 2018)
© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. The intensive use of insecticides such as chlorpyrifos (CPF) and diazinon (DZN) in the agricultural activities worldwide has produced contamination of soils ...
Soil physical properties and wheat root growth as affected by no-tillage and conventional tillage systems in a Mediterranean environment of Chile
(ELSEVIER SCIENCE BV, 2008-06)
No-tillage systems affect soil properties depending on the soil, climate, and the time since its implementation. In heavy no-tilled
soils a surface compacted layer is commonly found. Such layer can affect root growth and ...
Nonlinear electrostatic instabilities in the solar wind
(Blackwell Publishing Ltd, 2009)
It is well known that nonlinear electrostatic instabilities can be triggered in a plasma with streaming ion species in the presence of finite-amplitude Alfvén cyclotron waves. The instability occurs when the phase velocity ...
Organic carbon balance in Chilean volcanic soils after human intrusion and under different management practices
(TAYLOR & FRANCIS AS, 2007)
It is well known that humified soil organic matter ( SOM) plays a central role in soil fertility due to its chemical and physical properties, especially by sustaining soil biological and related ecological equilibrium. ...
