The growth of cereals under soil conditions characteristic of an unstable tilth

Summary In a series of experiments with winter cereals growing in pots, mechanical compaction of moist soil over wheat seed severely inhibited germination — no plants emerged from a compacted sandy loam soil. Conversely, the destruction of the surface tilth by falling water drops had no effect on the rate of emergence of either wheat or oats.Tillered wheat plants, growing at winter temperatures, survived prolonged adverse conditions of soil aeration.
