The purposeful application of lignocellulosic waste in forestry may regarded as one of the perspective avenues of its utilization. The use of peat containers for planting pine seedlings or regeneration of pine forest is currently increasing rapidly. However, it has the essential drawback, which is connected with a possible drying out of the peat container surface in the hot summer time that may course a mortality of seedlings. The simultaneous application of a binder and wood mulch such as sawdust may be considered as one of the most efficient methods for regulating the temperature-moisture conditions in the peat container. The binder, forming porous sawdust composite layers at the container surface, can prevent washout and deflation of the mulch, and, such a manner, contributies in regulating the temperature-moisture regime.
