Nitrogen Mineralization and Released Nutrients in a Volcanic Soil Amended with Poultry Litter
(Instituto de Investigaciones Agropecuarias, INIA, 2010)
Limos de baja densidad: impacto sobre el comportamiento físico de los suelos de la región pampeanaImpact of low-density minerals on soil physical properties of soils of the Pampean region
(Asociación Argentina de la Ciencia del Suelo, 2002-12)
Phytoliths are hydrated silica bodies that are included in plant tissues. Along with another bioliths and volcanic ashes, phytoliths are the main low-density mineral fraction in soils of the Pampa region. The aim of this ...
Canopy composition and site are indicative of mineral soil conditions in Patagonian mixed Nothofagus forests
(EDP Sciences, 2019-12)
Key message: Canopy composition in mixed Patagonian Nothofagus forests has an impact on soil properties like cationic exchange capacity and pH, while most soil variables changed with site [P, cation exchange capacity (CEC), ...
The Effect of Humic Substances and Phosphate Fertilizer on Growth and Nutrient Uptake of the Potato
(2020-06-16)
The use of applied phosphorus (P) and the uptake of nutrients from the soil by plants can be improved when the fertilizer is combined with the application of humic substances (HS). However, these beneficial effects are ...
Plant species and defoliation effects on soil nitrogen mineralization in a semiarid rangeland of Argentina
(Springer, 2021-09)
The objective of this study was to evaluate the effects of moderate defoliation and grass species on soil nitrogen (N) mineralization in a semiarid grassland of northeastern Patagonia, Argentina. Studied species were Poa ...
Effect of the pinus radiata on the chemical nutritive characteristics of surface mineral soil
(UNIV AUSTRAL CHILE, FAC CIENCIAS FORESTALES, 1995)
This paper relates two studies, each of which compared forest floor and upper mineral soil horizons between firstrotation Pinus radiata (21-27 years old) and secondary native forest of similar age and growth. The first ...
Spatial patterns of soil attributes and components in a mangrove system in Southeast Brazil (Sao Paulo)
(SPRINGER HEIDELBERG, 2010)
Purpose Among environmental factors governing innumerous processes that are active in estuarine environments, those of edaphic character have received special attention in recent studies. With the objectives of determining ...
Silvopastoral use of Nothofagus antarctica in Southern Patagonian forests, influence over net nitrogen soil mineralization
(2013-04)
In most temperate forest, nitrogen (N) is considered a limiting factor. This becomes important in extreme environments, as Nothofagus antarctica forests, where the antecedents are scarce. Thinning practices in N. antarctica ...
Soil carbon and nitrogen mineralization caused by pig slurry application under different soil tillage systems.
(Pesquisa Agropecuária Brasileira, Brasília, v.45, n.5, p.515-521, maio. 2010, 2014)
