Crop Yield Responses to Sulfur Fertilization in Brazilian No-Till Soils: a Systematic Review

Osmar Henrique de Castro Pias ORCID logo , Tales Tiecher, Maurício Roberto Cherubin, Michael Mazurana, Cimélio Bayer

06/Feb/2019

ABSTRACT Sulfur (S) fertilization recommendations for grain crops in Brazil were formerly established from studies on crops with a low yield potential grown on soils under conventional tillage (CT). However, the subsequent adoption of no-tillage (NT) altered S dynamics in the soil, making it necessary to carefully evaluate the applicability of these S fertilizer recommendations. In addition, the emergence of modern high-yield-potential genotypes, the successive application of concentrated low-sulfur fertilizers, and reduction in S atmospheric deposition have raised the likelihood […]

Soil Quality Evaluation Using the Soil Management Assessment Framework (SMAF) in Brazilian Oxisols with Contrasting Texture

Maurício Roberto Cherubin, Cássio Antônio Tormena, Douglas L. Karlen

29/Mar/2017

ABSTRACT The Soil Management Assessment Framework (SMAF) was developed in the U.S.A. and has been used as a tool for assessing and quantifying changes in soil quality/health (SQ) induced by land uses and agricultural practices in that region and elsewhere throughout the world. An initial study using SMAF in Brazil was recently published, but additional research for a variety of soils and management systems is still needed. Our objective was to use data from five studies in southern Brazil to […]

Soil quality (SQ) assessment is an important strategy for defining management practices and systems capable of maintaining and/or improving the sustainability of agricultural systems. Thus, the aim of this study was to evaluate changes in SQ by physical, chemical, and biological indicators in an Oxisol under different tillage systems and fertilizer sources. The study was conducted in Taquaruçu do Sul, RS, Brazil based on an experiment set up in 2009 in a randomized block design with four replications. The treatments […]

Changes in a Rhodic Hapludox under no-tillage and urban waste compost in the northwest of Rio Grande do Sul, Brazil

The use of urban waste compost as nutrient source in agriculture has been a subject of investigation in Brazil and elsewhere, although the effects on soil physical and chemical properties and processes are still poorly known. The aim of this study was to evaluate the effect of application of urban waste compost and mineral fertilizer on soil aggregate stability and organic carbon and total nitrogen content of a Rhodic Hapludox under no-tillage in the northwestern region of Rio Grande do […]

Soil penetration resistance, efficiency of mechanical chisel plowing and soybean grain yield in a clayey Oxisol under long-term no-till

Frequently, soil compaction limits the yield of grain crops in mechanized lands, and its spatial distribution in the cropland is usually regionalized. In an area managed under long-term no-tillage, we investigated the relationship between soil penetration resistance (PR) and soybean yield, the effectiveness of types of chisel plows, and their effect on soybean yield. The soil from the plateau region of the state of Rio Grande do Sul, Brazil, was classified as a clayey Oxisol. The climate is subtropical (Cfa […]
