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 ...

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 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 ...

Several legume and grass species, having roots of widely different cationexchange capacities, were grown in pots for four to six months on highly calcareous Turkish soil. Following the growth of the ...

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 ...

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 ...
