PEAT, BARK COMPOST AND BROWN COAL AS GROWING MEDIUM FOR GREENHOUSE TOMATOES

J.R. Starck, W. Oswiecimski, J. Wojciechowski
Pine bark is now easily available in Poland from paper mills. This bark is treated during the peeling process with hot water and the content of tannins drops from about 6 % to about 0.6 % (Ostalski — personal communication). Also brown coal is readily available as medium for plants in greenhouses. The above mentioned artificial media for plant growing are much cheaper than sphagnum peat moss. The aim of this paper was to compare these three substrates as growing media for greenhouse tomatoes.
