Changes in water retention curves caused by an addition of a soil conditioner (Solacrol) are discussed. The investigations were carried out on the different size aggregates of two types of soils. It was stated that stabilisation of soil aggregates changed the courses of water retention curves. The use of Solacrol generally caused a significant increase of retained water (above 5%) in case of Orthic Luvisol aggregates smaller than 3 mm for pF values below 2 and Haplic Phaeozem aggregates smaller than 0,5 mm for pF values below 1.5.
