Exchangeable basic cations and nitrogen distribution in soil as affected by crop residues and nitrogen
(Brazilian Archives of Biology and Technology, 2011-06-01)
In this work, a greenhouse experiment was conducted to study the effects of N fertilization and residues of pearl millet, black oats and oilseed radish on pH and Ca, Mg, K, NO3-, and NH4+ distribution within the profile ...

Zeólitas naturais: aplicação da clinoptilolita como trocadora de cátions
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de QuímicaQuímicaUTFPR, 2018-12-03)
This work aims to evaluate the potential of a silicate mineral from the zeolite group, a Clinoptilolite, for the treatment of marine residues containing potassium. Zeolites are hydrated aluminosilicates formed by ...
Rainfall reduction impacts rhizosphere biogeochemistry in eucalypts grown in a deep Ferralsol in Brazil
(2017-05-01)
Background and aims: Comparing root functioning under contrasting rainfall regimes can help assessing the capacity of plant species to cope with more intense and frequent drought predicted under climate change context. ...
The use of cation exchange resins in wines: effects on ph, tartrate stability, and metal content
(2018)
Treating wines with cation exchange resins allows the reduction of pi I and contributes to limiting the formation of tartrate salts by exchanging cations such as potassium with hydrogen ions. This manuscript summarizes the ...

Potassium fertilisation with humic acid coated KCl in a sandy clay loam tropical soil
(Csiro Publishing, 2018-01-01)
Loss of potassium (K) by leaching after potassium chloride (KCl) application is common in light-textured, low cation exchangeable capacity (CEC) soils with predominance of 1 : 1 clay minerals, and is aggravated as soil K ...
Diagnóstico da fertilidade do solo de áreas em implantação de agricultura de precisão no Rio Grande do Sul
(Universidade Federal de Santa MariaBRTecnologia em Agricultura de PrecisãoUFSMPrograma de Pós-Graduação em Agricultura de Precisão, 2013-09-02)
This study sought to describe the current state fertility levels by analyzing 105,342 soil samples from different regions of the state of Rio Grande do Sul assigned by CCGL Technology. Thus, about 42% of the samples need ...
