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 ...

Soils can be thought of as storehouses for plant nutrients. Many nutrients, such as calcium and magnesium, may be supplied to plants solely from reserves held in the soil. Others like potassium are ...

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 ...

THE cation exchange capacity of soils is due to inorganic constituents such as clay minerals, hydrous oxides, primary and secondary minerals and to organic matter. Estimates of the contribution of ...

A slight modification to Bascomb's procedure for determining cation exchange capacity makes it applicable to gypsic soils even when the gypsum content is as high as seventy percent. The modification ...

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 ...
