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 ... -
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 ... -
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: ... -
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 ... -
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 ... -
Fertilización nitrogenada en girasol en el suroeste de Chaco
(Facultad de Ciencias Agrarias, Universidad Nacional del Nordeste, 2014)La producción de girasol en la provincia de Chaco se ubica en el tercer lugar a nivel nacional, con rindes para la campaña 2010/2011 de 1860 kg ha-1. En este trabajo se plantea evaluar la respuesta de la fertilización ... -
Glyphosate dynamics in a soil under conventional and no-till systems during a soybean growing season
(2018-08-01)Glyphosate (GLY) is a non-selective herbicide, heavily used world-wide in agriculture, especially under no-tillage (NT) management. The objectives of this work were i - to determine the temporal and vertical variation of ... -
Hierarchy of factors driving N2O emissions in non‐tilled soils under different crops
(Wiley, 2013-10)Nitrous oxide (N2O) is emitted to the atmosphere as a by‐product of nitrification and denitrification by soil microbial processes. Differences in climate, soil and management regulate these processes, causing N2O emissions ... -
Impact of crop aerial and root biomass inputs on soil nitrifiers and cellulolytic microorganisms
(Elsevier, 2019)In agricultural no-till systems, crop residue management has an important impact on the activity and abundance of soil microorganisms, which play a crucial role in soil health and quality. In these systems, when cover crops ... -
