Effects of Balancing Exchangeable Cations Ca, Mg, and K on the Growth of Tomato Seedlings (Solanum lycopersicum L.) Based on Increased Soil Cation Exchange Capacity

Agronomy
(1) Background: Previous research has demonstrated that the cation exchange capacity (CEC) of soil and the balance of exchangeable cations Ca, Mg, and K are key factors affecting plant growth and development.

Silver-containing Cation Exchange Resin: Synthesis and Application

Medžiagotyra, 2022
Cation exchange resins are widely used for water softening and demineralization all over the world. Deposition, metabolism, and growth of bacteria and fungi on the resin beads cause capacity and performance losses, especially during repeated use in ...

Exploring the link between cation exchange capacity and magnetic susceptibility [PDF]

SOIL
This study explores the relationship between soil magnetic susceptibility (κ) and cation exchange capacity (CEC) across diverse European soils, aiming to enhance pedotransfer functions (PTFs) for soil CEC using near-surface electromagnetic geophysics. We

Selected properties of cobalt-contaminated soil following the application of neutralising substances

Environmental Protection and Natural Resources, 2016
The aim of the study was to determine the influence of increasing cobalt soil contamination (0 mg·kg−1, 20 mg·kg−1, 40 mg·kg−1, 80 mg·kg−1, 160 mg·kg−1, 320 mg·kg−1) after the application of neutralising substances on selected soil properties.

Contribution of the chemical and mineralogical properties of sandy-loam tropical soils to the cation exchange capacity

, 2020
Soils originating from the Caiua sandstone formation have low soil organic matter (SOM), clay content, and cation exchange capacity (CEC). The predominance of one component over the other might decisively influence the CEC of these soils.

Exchange Characteristics of Lead, Zinc, and Cadmium in Selected Tropical Soils

International Journal of Agronomy, 2014
Conducting binary-exchange experiments is a common way to identify cationic preferences of exchangeable phases in soil. Cation exchange reactions and thermodynamic studies of Pb2+/Ca2+, Cd2+/Ca2+, and Zn2+/Ca2+ were carried out on three surface (0–30 cm)
