Abstract

Using soil-filled plastic cylinders with a controlled atmosphere in contact with the soil surface, the limiting aeration requirements of 5 crop spp. including pea, oats and potato were measured, with O2 diffusion rate values as a parameter. Pea had the highest requirements, oats the lowest, while potato was intermediate. This sequence corresponded rather well with field experience. Shallow rooting as a result of poor soil aeration could restrict the uptake of a number of mineral nutrients. In these experiments, P and K were more often severely restricted than Ca or NO3.
