The effects of cultivation treatment on water potential and soil aeration in wet heathland with special reference to afforestation.
Describes a study in north Yorkshire comparing the effects of the following treatments on soil aeration, water potential, and growth of Pinus sylvestris up to 8 years after establishment : deep single-furrow ploughing; deep complete ploughing; and the construction of elevated ridges (riggs) separated by deep furrows (furrs). Some plots in each treatment were supplied with drains. Results show that the construction of riggs and furrs improved drainage and aeration, compared with the other treatments and that these improvements gave better tree growth. The construction of larger riggs and their more extensive experimental application are recommended.
