Preplant Lime and Micronutrient Amendments to Pine Bark Affect Growth of Seedlings of Nine Container-grown Tree Species
- A. Wright, A. Niemiera, J. R. Harris, R. Wright
- Biology
- 1 July 1999
Pine bark is a common container substrate used by nurseries in the southeastern United States and is often preplant amended with lime and micronutrients, and the rationale for liming is to increase pH of acidic bark.
