Crop‐Pasture Rotation for Sustaining the Quality and Productivity of a Typic Argiudoll
Soil Science Society of America Journal, 1997Abstract Inclusion of pastures in a rotation may reverse the effects of conventional cropping and tillage on soil degradation. We hypothesized that crop‐pasture rotations could be defined with a minimum pasture component and a maximum conventional cropping component to accomplish sustainable management.

The objective of the present study was to determine the effect of tillage systems on the activities of enzymes associated with the carbon (C) and nitrogen (N) cycles (β‐glucosidase and protease) on a Typic Argiudoll (Marcos Juarez Series). The experiment was performed in a randomized complete block design with three replications under no till ...

Soil and Tillage Research, 2016
Abstract Soil organic matter affects a number of soil processes and properties. A better understanding of soil-profile distribution of organic matter components and related soil properties under long-term tillage systems is thus needed. The objective of this study was to evaluate the impacts of 33 years no-till (NT), double disk (DD), chisel (CH ...

The sorption and desorption of diuron by soil samples from Horizons A and B (HA and HB) and by their different clay fractions were investigated, using two soil samples, classified as Typic Argiudoll and Oxic Argiudoll. The sorption and desorption curves were adjusted to the Freundlich model and evaluated by parameters Kf, Kd and Koc.

Soil and Tillage Research, 1996
Abstract Farmers are increasingly using zero tillage in Central Argentina to replace other tillage systems. Intensive tillage decreases soil organic matter content and causes physical degradation. The objective of this work was to evaluate changes in some soil biological properties induced by different tillage systems.

Size Spectra of the edaphic fauna of Argiudol typical soils of the rolling Pampa region, Argentina
2023La fauna del suelo habita en los intersticios formados entre la basura que se acumula en la superficie del suelo y los poros que existen en la matriz organo-mineral del suelo. Estos organismos juegan un papel muy importante en el funcionamiento del ecosistema edáfico relacionado con el fraccionamiento y descomposición de la materia orgánica, el ...

Influence of drought on the production of mineral nitrogen in a typical argiudol of the pampas
Soil Biology and Biochemistry, 1993Abstract A typical Argiudol of Pergamino (Buenos Aires province) was sampled in August 1988 and April 1989. The samples were air-dried at room temperature. Samples were analyzed at different times with regard to: (a) real and potential ammonification, i.e.

COLUMN TRACER STUDIES IN SURFACE AND SUBSURFACE HORIZONS OF TWO TYPIC ARGIUDOLLS
Soil Science, 2008Soil properties that vary in space and/or time within a soil profile introduce heterogeneity to solute transport. The objectives of this work were to (i) study transport of bromide through the horizons of two soils under no-tillage but differing in soil structure and organic carbon content, and (ii) determine the nature of the process by fitting ...

Abstract Soil morphology and hydraulic conductivity ( K ) of principal soil horizons of paired virgin and cultivated soil pedons were studied at two sites: a Tama silt loam (Typic Argiudoll) and an Oshkosh clay (Typic Eutrochrept).
