Porosidade de aeração de um Latossolo Vermelho e rendimento de trigo em plantio direto escarificado Air-filled porosity in Latosol and wheat grain yield under no-tillage chiseled

Ciência Rural, 2008
Proporcionar condições ótimas ao desenvolvimento das plantas deve ser um dos objetivos do manejo do solo. O sistema plantio direto é um manejo conservacionista por excelência, mas tem apresentado problemas de compactação, afetando o desenvolvimento e à ...

Mechanical Intervention in Compacted No-Till Soil in Southern Brazil: Soil Physical Quality and Maize Yield

Agronomy, 2022
The intense and successive use of mechanization in modern cropping systems has increased soil compaction under no-till areas. In this study, we aimed to assess the performance of a fixed shank coupled with a seeder for the mitigation of soil compaction ...

Decoupling glacier retreat and surface stabilization on the Snežnik Plateau (Slovenia), insights from in situ cosmogenic 36Cl exposure and depth‐profile ages

Journal of Quaternary Science, EarlyView.
ABSTRACT Glaciokarst landscapes pose distinctive challenges for cosmogenic dating because meltwater and runoff can be rapidly rerouted into ponors and conduit networks, weakening glacier–river coupling and promoting local sediment storage. We reconstruct glacier retreat and postglacial stabilization on the Snežnik Plateau (SW Slovenia) using in situ ...

Mechanical Chiseling Versus Root Bio-Tillage on Soil Physical Quality and Soybean Yield in a Long-Term No-Till System

Agronomy
Occasional mechanical intervention can help alleviate compaction symptoms in no-till systems, but its effects compared to well-established crop rotation systems are uncertain.

Sport participation after isolated distal femoral osteotomy in young patients: High return‐to‐sport rates and predictive role of preoperative activity level

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The present study aimed to assess return to sport (RTS) rate, activity level and return to work (RTW) in young, physically active patients who underwent isolated distal femoral osteotomy (DFO) for lateral knee pain and valgus malalignment.

Sediment transport in runoff on rugous soil surface submitted to simulated rainfall Sedimentos transportados na enxurrada em superfície de solo rugosa submetida à chuva simulada

Scientia Agricola, 2010
Soil management influences water erosion and sediment size in runoff. With the objective of quantifying sediments in runoff and their relation to runoff velocity (Rv), random roughness (RR), and Ir index, this experiment was carried out from 2003 to 2006,
