DEPOSIT OF THE LISINA PHOSPHATES LIKE THE BASE OF RAW MATERIALS FOR PRODUCTION THE NATURAL MINERAL FERTILIZERS

摘要

Deposit of the Lisina phosphates is in the southeast of Serbia, on the territory of the community Bosilegrad, close to Serbian-Bulgarian border. Genetically, the deposit of the Lisina phosphates belongs to the metamorphic deposits. Narrow area of the deposit is built by metamorphk formations with intensively presence of granitoids rocks. Phosphorites are in the contact zone of'he Meta sandstone which is the floor of sericile-chlorite slates with intercalations of marble and kalkshist in the roof Raw phosphates can be. applied as fertilizers with the positive effect: on the territory of Serbia where are mostly the acid soils on more than 50% of the territory.
