Cation exchange capacity (CEC) is an important characteristic of zeolites, especially when they are used as adsorbents in the aqueous system. However, no international standard method exists for the determination of CEC of zeolites. We determined CEC of Linde-type A and Na-P1 type zeolites at various pH (4 to 10) with a simple method, where Na+-saturated zeolites were prepared, and then various...

Adaptation of fine root plasticity to soil nutrients heterogeneity in natural forest ecosystems has not been well explored. The study aimed determine seasonal variations traits Pinus koraiensis forests and explore the relationship between properties. Root samples were collected from coniferous broad-leaved mixed (BP), monospecific P. (MP), (CP). Soil available phosphorus (P) content for MP was ...

Many students in introductory soil science and soil chemistry courses have difficulty understanding the chemical concepts that are associated with expressing cation exchange capacity in either equivalent units or the International System of Units (SI). This paper is intended as a handout o help beginning soils students understand these chemical concepts using a step-by-step review of chemical u...

To address the problems of soil acidity (pH values below 4.4) in surface and subsurface layers improve chemical fertility, this study evaluated three methodologies for application limestone (LS) (ensuring that calcium (Ca)2+ occupied 70%, 60% or 50% cation exchange capacity (CEC) at a depth 0.0–0.2 m) gypsum (GP, phosphogypsum) Ca2+ 60%, 40% effective (ECEC) 0.2–0.4 m). LS GP were applied conve...

To estimate the Cation Exchange Capacity (CEC), indirect manner used of Pedotransfer Functions (PTFs). CEC is one of the important soil fertility factors, and not measured directly because it is costly and time consuming. Thus, used from regression equations between easily and non-easily soil properties. The purpose of this research, is develop the PTFs for CEC, with use of easily available soi...

Ecotechnology may be a never-ending applied science to all mankind. Often and we know that in recent days Machine learning Techniques can used for mankind obtaining significant relations. Present research communication dealt with long-run fisheries when find cation exchange capacity viz. CEC total dissolved solids TDS have roles controlling fish diseases hence also growth fecundity. There no of...
