Researchers determined the variability of cation exchange capacity in different batches of pine bark and studied the influence of particle size, substrate pH, and peat amendment on CEC. Part of the ...

Soils have a natural characteristic called the cation exchange capacity (CEC) that allows them to hold (and exchange) cations (e.g., Ca+2 or Na+). These cations are held tight enough on the CEC that ...

Sample pretreatment processes such as concentration or classification are essential to finding trace substances present in a fluid. In scientific communities recently, prolific research is being ...

Vol. 146, No. 1/2, Selected papers from the PROCEEDINGS OF THE FOURTH INTERNATIONAL SYMPOSIUM ON GENETIC ASPECTS OF PLANT MINERAL NUTRITION (October 1992), pp. 77-82 (6 pages) Genotypic differences in ...

ARISING from an investigation of the variation in positive and negative charge with p H in a number of ferruginous tropical soils 1, it appeared that the use of alcohol washings in the determination ...

The soil under intensive cultivation and low addition of crop residues is exposed to erosion and reduction of organic matter. Increases in soil organic matter, cation exchange capacity (CEC) and ...

WOOSTER, OH - A new study contains valuable recommendations that can inform container nursery fertilization practices in the northeastern United States. In this region, most nursery substrates are ...
