Soil organic matter-metal interactions in Chilean volcanic soils under different agronomic management
(MARCEL DEKKER INC, 2002)
The organic matter existing in volcanic soils must be investigated not only in quantity, but also in quality in order to understand its role in soils and thus ensure adequate levels of stable organic polymers contributing ...
Non-labile plant C contributes to long-lasting macroaggregation of an Oxisol
(2013-03-01)
Decomposition of plant material influences soil aggregation dynamics in ways that are still poorly understood, especially for Oxisols, in which oxides are believed to play a dominant role. In an incubation experiment, we ...

Phosphorus Sources Combined with Doses of Organic Compost Increased the Population of Soil Microorganisms and P Level in the Soil and Plant and the Dry Matter of Sugarcane
(2020-01-01)
The aim of the study was to evaluate the effect of P sources and filter cake, enriched or not with biofertilizers and liquid peat, on the microbial population and the soil available P levels and shoot dry matter and P ...
Crop rotation in no-till soils modifies the soil fatty acids signature
(Wiley Blackwell Publishing, Inc, 2018-09)
Analysis of whole-soil fatty acids (WSFA) was used to characterize no-till productive agricultural soils associated with different crop rotation managements on the Argentinean pampas, over two sampling seasons. Crop rotation ...
Measurement of metal-complexing ability of polyfunctional macromolecules: a discussion of the relationship between the metal-complexing properties of extracted soil organic matter and soil genesis and plant nutrition
(The Williams & Wilkins Co., 1975)
Characterization of the metal-complexing ability of polyfunctional macromolecules through the determination of stability constants of their metalic complexes is discussed along with the validity of ascribing a relationship ...
Degradation of monensin on soils: Influence of organic matter and water content
(Taylor & Francis Ltd, 2010-02)
Different kinds of pharmaceutical compounds (PhC) are used in veterinary medicine. Intensive bovine production involves the use of growth promoters that reach the environment through animal excreta. The most widely used ...
Estimativa Da Água No Solo Em Floresta de Eucalyptus Grandis
(2012-12-01)
The study aimed to assess the moisture and density of the soil, the amount of water stored in the profile, and the average soil's porosity with Eucalyptus grandis reforestation, compared to bare soil. The study areas are ...
