The results of birth growth investigation in the 9 year old plantation on the abandoned podzolic soils of agriculture lands are assumed. The planting density was 1100; 1600; 2500; 5000 and 1000 plants per hectare. The average heights have reached 5.31 and 5.36 m, but average DBH 5.38 and 5.36 cm in the plots with 10 000 and 5000 trees per hectare accordingly. The average height has reached 6.47; 6.65 and 6.73 m but average DBH 7.17; 6.67 and 7.38 cm in the plots with 2500; 1000 and 111 trees per hectare accordingly. The average height and average DBH of trees in the dense plantations is essential (P is less than 0.0001) lower, but the average standing grows volume higher. The losses of trees per mine years reached about 15%. For the production of fuel wood can be recommended plantations with height density.
