Addition of amendments to restore a compacted soil under no-tillage system
(Universidade Estadual de Maringá, 2023-04)The addition of organic and inorganic amendments can improve soil structure and reduce soil compaction. In this context, this study aimed to evaluate whether the application of amendments reduces penetration resistance ... -
Addition of organic and inorganic amendments to regenerate the surface structure of silty soils
(Wiley, 2019-11-30)The widespread degradation of the structure of silty soils under no till systems (NT) that has been observed in recent years is characterized by the presence of a platy structure (P) near the soil surface. Under these ... -
Adsorption and mobility of glyphosate in different soils under no-till and conventional tillage
(2016-02)El glifosato (N- (fosfonometil) glicina) es un post-emergencia, no selectivo, herbicida foliar. Alrededor de 200 millón de litros de este herbicida se aplican cada año en Argentina, donde la principal práctica agrícola es ... -
Biomass Decomposition and Phosphorus Release from Residues of Cover Crops under No-Tillage
(2017-01)Under no-tillage field conditions, cover crop (CC) residues remain on the soil surface and decompose at a slow rate. We used three CC species (oat, Avena sativa L.; rye, Secale cereale L.; and ryegrass, Lolium multiflorum ... -
Carbon and nitrogen sequestration in soils under different management in the semi-arid Pampa (Argentina)
(Elsevier, 2014-09)Soil management affects distribution and the stocks of soil organic carbon and total nitrogen. The aim of this study was to evaluate the effect of different crop sequences and tillage systems on the vertical distribution ... -
Complementary irrigation and direct drilling have little effect on soil organic carbon content in semiarid Argentina
(Elsevier, 2013-11)Irrigation and tillage modify soil properties. The aim of the present study was to evaluate the simultaneous effect of complementary irrigation and zero tillage (ZT) on soil organic carbon (SOC). Two treatments (irrigated ... -
A contribution to understanding the origin of platy structure in silty soils under no tillage
(2016)In silty soils under no tillage (NT), platy (P) soil structure is widespread and constrains water infiltration. Our objectives were (i) to evaluate how traffic and the presence of crop residues influence P structure ... -
Cover crop effects on soybean residue decomposition and P release in no-tillage systems of Argentina
(2014-11)Cover crops (CC) provide many benefits to soils but their effect on decomposition of previous crop residues and release of nutrients in continuous no-tillage soybean [Glycine max (L.) Merr.] production are little known. ... -
Cover crops effects on anisotropy of unsaturated soil hydraulic properties
(Elsevier, 2023-03)No tillage (NT) is frequently implemented in simplified agricultural systems, which has negative effects on soil physical quality. Among the suggested practices to preserve the physical fertility of soils under NT are ... -
¿Cómo iniciar los cultivos hortícolas en labranza cero o siembra directa?
(EEA Hilario Ascasubi, INTA, 2017-05)En el INTA Hilario Ascasubi se desarrollan estudios sobre la aplicación de la labranza cero en el cultivo de ajo, cebolla y zapallo con muy buenos resultados. -
Crop sequence and P fertilization effects on soil P fractions under no-tillage
(Springer, 2021-05-27)Increasing cropping intensity may affect phosphorus (P) recycling through crop residue inputs, which may differ in soils with different productivity, P adsorption capacity, and P fertilization level. In three crop sequences: ... -
Depth distribution of soil, glyphosate, and aminomethylphosphonic acid (AMPA) properties and analysis of crop yield in six long-term experiments
(Springer, 2023-03-21)Context: Argentina is the third-largest user of pesticides per year, with more than 65% of the herbicide being glyphosate. Glyphosate and aminomethylphosphonic acid (AMPA) have similar properties in terms of environmental ... -
Developments in the “profil cultural” method for an improved assessment of soil structure under no-till
(Elsevier, 2017-11)In France, agronomists have studied the effects of cropping systems on soil structure using a field method that is based on a visual description of the soil structure. This “profil cultural” method was designed as a field ... -
Ecosystem and productive benefits of the strategic inclusion of annual legumes into an annual ryegrass pasture in a no-tillage integrated crop-livestock system
(Ediciones INTA, 2021-12)Annual winter pastures are strategic components in crop-livestock systems in Uruguay. The aim of this study was to evaluate the N legume fixation into an annual ryegrass pasture contrasted to the N fertilizer addition. The ... -
Edaphic forms of phosphorus in no-tillage cropping sequences in the Argentine southern central Pampas
(2018-08)Agriculture significantly affects phosphorus (P) availability, thereby modifying P equilibrium. The objective of this study was to evaluate the effect of different crop sequences on the dynamics of soil P forms under no ... -
Efecto de sistemas de labranza contrastantes sobre algunas propiedades de un molisol de Tres Arroyos bajo distintos usos previos
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2012)El proceso de "agriculturización" se define como el uso creciente y continuo de tierras para cultivos agrícolas en lugar de usos ganaderos o mixtos. El objetivo del trabajo fue evaluar el efecto de diez años de ... -
Effect of continuous agriculture of grassland soils of the Argentine Rolling Pampa on soil organic carbon and nitrogen
(2013)Long-term soil organic carbon (SOC) and soil organic nitrogen (SON) following cultivation of grassland soils (100/120-year tillage (T) + 20/30-year no tillage (NT)) of the Rolling Pampa were studied calibrating the simple ... -
Effect of conventional and no-till practices on solute transport in long term field trials
(Elsevier, 2014-09)The prediction and description of water and solute movement in soils under different tillage systems is essential to the study of pesticide contamination in soils and groundwater quality. However, the impact of tillage ... -
Effect of different cover crops on C and N cycling in sorghum NT systems
(2016)In many no-till (NT) systems, residue input is low and fallow periods excessive, for which reasons soil degradation occurs. Cover crops could improve organic matter, biological activity, and soil structure. In order to ... -
