On 3 grassland habitats (fertile, average, poor) in Piotrkow province the type, moisture content and biological activity of the soil as well as hay yields and botanical composition were studied. Water deficiency in all habitats, especially in the poor one, caused periodical drying of sward plants and formation of poor xerothermic communities. On fertile and average habitats considerable fluctuation in yielding connected with water deficiency and similarizing of plant communities to poor habitat were observed. The factors differentiating all these habitats were the thickness of accumulation soil horizon and biological soil activity, especially soil dehydrogenase content
