The efficiency of leguminous and Brassica siderates plants to increase the biological activity of soils, crop capacity and quality of cereals was tested in stationary field tests and agricultural laboratories at the State Stende Plant Breeding Station during the period 1996 to 1999. The tests confirmed that red clover, sweet clover, alsike clover, alfalfa and lupine siderates improved organic matter content in the soil in the best way (+0.4%-0.9%), while annual ryegrass showed the lowest percentage (0.1%-0.2%). Barley monoculture was used as control. Leguminous siderates increased winter wheat, barley and oats yield compared to Brassica siderates. Particular crop grain increase was obtained with mustard siderates. The highest protein increase was established under the influence of leguminous siderates. For the period of three years the incorporation of red and alsike clovers into soils provided the highest extra income.
