Experimental Design
Design (short description): 
Nitrogen has been applied in rate 300kg/ha yearly since 1950. Upper knots were intensively cut in 1950 & 1969 120kg/ha of phosphorus & potash were applied before 1952, but in the period from 1953 to 1968 these nutrients were not applied at all, since 1962 applied periodically once each 4 years with bulk application of 4 year's rate. Magnesium was applied once in 1977, rate 100kg/ha MgO
Permanent plot area (square meters): 
1000-3000
Number of permanent plots: 
>20
Soil Classification
Soil taxa (ex, Great Group of Soil Taxonomy): 
Soil FAO type description: ferrisol Russian classification: red soils Description of native red soil horizons A0 horizon (sod or litter layer) -- 3-4cm, contains partly decomposed fern and trees' leaves. A horizon (humus horizon) -- greyish-dark brown, cloddy - granular loose structure, clay loam, abundant of fern roots -- 20-25cm thickness. B1 horizon - transition horizon, cloddy, clay-loam & clay, slightly compact B2 horizon -- brownish-red with black & light-yellow mottles, more compact than previous horizon, thickness of B1+ B2 is more than 35-45cm C horizon -- parent rock, with heterogeneous red color, abundant big Fe-Mn nodules & light-yellow Si mottles, subangular cloddy structure, clay loam, compact.
