Soil tillage systems: changes in soil structure and crop response

open access: yesRevista Brasileira de Ciência do Solo, 2011
The introduction and intensification of no-tillage systems in Brazilian agriculture in recent decades have created a new scenario, increasing concerns about soil physical properties.

Chiseling and gypsum application affecting soil physical attributes, root growth and soybean yield

open access: yesRevista Ciência Agronômica, 2019
This study aimed to evaluate the effect of chiseling and gypsum application on soil physical properties, soybean root growth and grain yield. An experiment was carried out in Londrina, Paraná state, Brazil, under a randomized complete block design, with ...

Physical and chemical changes in soil fertilized with poultry manure with and without chiseling

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2016
Poultry manure and mechanical management may influence the distribution of nutrients in the soil profile. The objective was to evaluate physical and chemical changes in a soil with palisade grass ( Brachiaria brizantha cv.

NEW MASTOID CHISELS [PDF]

open access: yesJournal of the American Medical Association, 1912
There are various mastoid chisels in use, some being acutely rounded at the end, some being square, others having concaveconvex bodies and still others being flat. All have their advantages and their disadvantages. Those with markedly rounded cutting edges allow the apex to sink into the bone before the sides, and thus necessitate uncertain chiseling ...

Prototype for soil mechanical resistance measurement with chisel plow automated control [PDF]

open access: yesEngenharia Agrícola, 2016
In Brazil, there are several available models and systems to measure soil compaction; however, the data generated by such equipment have to be processed and interpreted, making the process expensive.

Corn in postcut crops

open access: yesНовые технологии, 2023
In agrotechnologies postcut crops of intermediate cultures are placed after harvesting annual grasses for green mass, and stubble crops after harvesting early grain crops. Annual herbs at the April sowing dates reach mowing maturity and are harvested for

Morpho‐functional analyses of the jaw apparatus in the Blue‐and‐yellow Macaw (Ara ararauna, Psittaciformes, Aves): Adaptations to feeding behavior

open access: yesThe Anatomical Record, EarlyView.
Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

Repositioned Kirschner Wires as a Temporary Metaphyseal Block to Prevent Articular Extension During Opening‐Wedge High Tibial Osteotomy

open access: yesArthroscopy Techniques, EarlyView.
Abstract Lateral hinge fracture is a frequent complication of medial opening‐wedge high tibial osteotomy. Previous strategies—such as inserting an additional third Kirschner wire (K‐wire) from the lateral tibial cortex—reinforce the lateral cortex but do not address the potential fracture line that propagates proximally toward the tibial plateau and ...
