Experimental Design
Design (short description): 
Land-use/Version: Green corn, Winter Sugar, Silage corn, wheat, beet Without fertilizers , Organic fertilizers, Mineralic fertilizers (which have been chosen for LASSEE project) 1. Nil input, 2. PK, 3. NPK, 4. FYM Crop rotation: green corn-winter wheat-sugar beet-silage corn Total rates of fertilizers applied during 1967-87 1. Nil inputs, 2. P200K200, 3. N950P200K200, 4. 280 tonnes of FYM Each ha of the experimental area has received in average: N - 87,5 kg, P - 60 kg, K - 60 kg, FYM - 14 t Crops after closing of the experiment: 1987 - Winter wheat, 1988 - Green corn, 1989 - Winter wheat 1990 - Fodder beet, 1991 - Barley, 1992 - Buckwheat 1993 - Winter wheat, 1994 - Buckwheat, 1995 - Millet, 1996 - Vetch-oats mixture (for hay), 1997 - Winter wheat, 1998 - Vetch -oats mixture (for grain) 29/09/98 Sampling depth: 0-30, 30-60 cm Treatments: 1. Nil imputs 2. PK 3. NPK 4. FYM Replications: 2 Method of sampling: 1 bulked sample from each plot have been re- ceived based on 3 individual cores. Total - 16 bulked samples In the other field (Field N 2) the same type of experiment was es- tablished in 1968 and have continued with the same fertilisers input. Additional metadata : For the period of experiment on that field min T 4,1 meanT 6,6 max T 9,3 Precipitation min 253 mean 409 max 581 Total rates of fertilizers applied during 1968-98 1. Nil inputs 2. P930K910 3. N1010P930K910 4. 376 tonnes of FYM Crop rotation have been changed in 1992: silage corn-winter wheat-sugar beet -vetch-oats (grain) - winter wheat-grain corn-spring barley Sampling in the framework of LASSEE project: 29/09/98 Sampling depth: 0-30, 30-60 cm Treatments: 1. Nil imputs 2. PK 3. NPK 4. FYM Replications: 2 Method of sampling: 1 bulked sample from each plot have been re- ceived based on 3 individual cores. Total - 16 bulked samples

Soil Classification
Soil taxa (ex, Great Group of Soil Taxonomy): 
Russian classification: Soil type - typical deep chernozem, clay loam, deep, with medium humuslevel on brownish calcerious loess loam. FAO: Haplic Chernozem rooting depth - 80-90 cm Impermable layer - 4.5-5 m Groundwater level - 10 m H dark grey, heavy loam; 0-30 cm - arable layer, 0-50cm granular-cloddy structure; 30-50 - granular structure, loosy, wet, gradual transition. Hp upper transitional, high humus content , dark grey,granular. 50-89 cm -cloddy structure, heavy loam, slightly compact,wet, effervescence line from 76 cm, calcareous pseudomycelium, piersed by roots, abundant crotovinas, distinct transition; Phca lower transitional, low humus content,mottled,brownish grey 89-118 ám with more pronounced pale brown down the profile, smaller pronounced non-uniform humus colour, subangular structure, heavy loam, compact, wet, reworked by animals,crotovinas contains material of the upper layers, distinct transition. Pca loess loam,pale brown, heavy loam, 118-200 cm fine porosity with abundant calcareous pseudomycelium
