AFFORESTATION OF DEGRADED KARST AREAS BY SOWING Summary In the introduction the author deals with the question of economy of work in the afforestation of degraded Karst region and states that sowing would be by far cheaper than planting. Into consideration is taken natural afforestation through seedling; pointed out are the conditions under which this occurs in nature. Reference is imade to factors under which naturali regeneriatjion through seeding is possible, and emphasis is laid on the ecological conditions under which it comes into being. The large quantities of seed and the long time intervals in which natural seeding occurs are pointed out. Conditions are ditfcussed for the establishment of forest in degraded Karst areas and especially conditions which are unfavourable as regards the soil characteristic and fructification. The unfavourable climatic factors during the germination of seed are likewise mentioned. There is scarcity of water during the drought periods which causes the dying away of new growth because of the dessication of the soil or inefficient protection against the insolation and because of the action of other factors. The author also discusses the history of sowing on the degraded Karst region as well as the opinions of specialists concerning these activities. It is stated that sowing was successful only__with a few Pine species. Mention is made of species with which most of the sowing trials were made, and he estimates the results to have been poor. Then the author reports on the method of afforestation such as: sawing with dibble, sowing in prepared patches and braadcast sowing. He explains the .successful broadcast sowing of P. Halepensis and of P. nigra ssp. austriaca in |
