Using Soil Apparent Electrical Conductivity to Optimize Sampling of Soil Penetration Resistance and to Improve the Estimations of Spatial Patterns of Soil Compaction

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
This study presents a combined application of an EM38DD for assessing soil apparent electrical conductivity (ECa) and a dual‐sensor vertical penetrometer Veris‐3000 for measuring soil electrical conductivity (ECveris) and soil resistance to penetration (PR).

Chemical Attributes of Soil Fertilized with Cassava Mill Wastewater and Cultivated with Sunflower

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
The use of waste arising from agroindustrial activities, such as cassava wastewater, has been steadily implemented in order to reduce environmental pollution and nutrient utilization. The aim of this study is that the changes in chemical properties of dystrophic red‐yellow latosol (oxisol) were evaluated at different sampling times after reuse of ...

Using Multivariate Geostatistics to Assess Patterns of Spatial Dependence of Apparent Soil Electrical Conductivity and Selected Soil Properties

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
The apparent soil electrical conductivity (ECa) was continuously recorded in three successive dates using electromagnetic induction in horizontal (ECa‐H) and vertical (ECa‐V) dipole modes at a 6 ha plot located in Northwestern Spain. One of the ECa data sets was used to devise an optimized sampling scheme consisting of 40 points.

Influence of Corn (Zea mays L.) Cultivar Development on Grain Nutrient Concentration

International Journal of Agronomy, Volume 2012, Issue 1, 2012., 2012
While corn productivity has been increased by the adoption of high‐yield hybrids, there are concerns that increased grain potential may be associated with diminished grain nutrient concentration. Ten corn (Zea mays L.) cultivars representing five technological levels (landrace variety, commercial variety, and double, triple, and single cross‐hybrids ...

Global trends and challenges in biogas purification and CO2 capture for renewable energy and climate mitigation

Biofuels, Bioproducts and Biorefining, Volume 19, Issue 6, Page 2474-2494, November/December 2025.
Abstract Biogas purification technologies facilitate the production of value‐added products such as biomethane and industrial chemicals. This review was based on the assumption that biogas purification is underrepresented in the literature despite its significant potential for clean energy and greenhouse gas mitigation, warranting a comprehensive ...

A pedo‐isotopic approach to study sandy soils of the Brazilian Cerrado in Piauí State

Agrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract Sandy soils dominate Brazil's Cerrado biome in Piauí State, yet their organic carbon (OC) stabilization mechanisms and landscape‐driven pedogenesis remain poorly understood. To clarify this topic, the present study proposes a pedo‐isotopic approach to characterize six representative Brazilian Cerrado soils derived from sedimentary rocks in ...

Combined use of O3/H2O2 and O3/Mn2+ in flotation of dairy wastewater

Revista Ambiente & Água, 2018
This work investigated the degradation of organic matter present in synthetic dairy wastewater by the combination of ozonation (ozone (O3)/hydrogen peroxide (H2O2)) and catalytic ozonation (ozone (O3)/manganese (Mn2+)) associated with dispersed air ...
