The paper presents data conceming factors affecting the air conditions in soils. Effect of temperature on respiration of roots and microorganisms are discussed. Grasses has a good tolerance for a low oxygen concentration as compared with other crops. Nevertheless there are differences among species of grasses as regards reaction on oxygen diffusion rate (ODR). Presented data show that the ODR at 1 cm and 5 cm depth were often considerably lower than those at greater depths. This points toward a higher diffusion resistance in the upper centimeters o f the top layer, which must have been caused by compaction and blocking of the pores by roots of grasses.
