In horticulture, the management of waste products arising in the processing of wood concerns the prompt recovery of organic substances already produced, in order to re-use them without contaminating the natural environment. The results of experiments presented in this paper are the outcome of investigations conducted during recent years since 1970. concerning the versatile use of waste products for vegetables grown under glass and plastic. Former investigations have shown the great usefulness of bark and sawdust from coniferous trees as components of substrates mixed with black peat (in different proportions) for growing cucumbers and tomatoes under glass and plastic. They have also revealed that it is possible to use non-composted pine bark and sawdust from coniferous trees as fertilising material in the growing of lettuce, tomatoes and cucumbers in plastic tunnels. Bark and coniferous sawdust mixed in suitable proportions with dried hen droppings may also be used as a biological heating layer in the culture of stenothermal vegetables. Using the hot fermentation period of this material in the growing of vegetables under glass and plastic is a method which aims to save energy resources used both for heating protected growing areas, and for CO(,2) production. In Poland considerable quantities of beech wood are also processed in paper mills. The waste products, mainly the bark, are very considerable. Research over three years into compost from beech for growing cucumber and tomato under glass and plastic, as well as a soil improver for growing lettuce, tomato and cucumber under plastic proved the feasibility of such types of use.
