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 ...
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: 1. Hypothesis interpreting the role of soil organic matter in the translocation of metal ions from rocks to biological systems
(1977)
The role of naturally-occurring soil organic matter (SOM) in the translocation of metal ions from parent materials to biological systems is discussed. To explain the movement of essential elements, a hypothesis or model ...
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 ...
Ion acoustic instability triggered by finite amplitude polarized waves in the solar wind
(Blackwell Publishing Ltd, 2005)
[1] It is shown that ion-acoustic waves propagating along an external magnetic field and
generated by parametric decays of circularly polarized finite amplitude waves have the
properties of ion-acoustic waves observed ...
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 ...
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 ...
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 ...
Preliminary survey of some soils from chilean altiplano near iquique
(2011)
In the Altiplano of the Iquique Province, Chile, a study was carried out for the purpose of advancing in the knowledge of the soils in the zone, to determine the soil moisture and soil temperature regimes, and to establish ...
