Abstract
A modified method for the measurement of Air Filled Porosity (AFP) has been developed by the Research & Development Department of Bord na Mona, Ireland in order to provide a robust laboratory method for the determination of the drainage properties of peat substrates destined for use in nursery stock.
A special vessel with a rigid extension collar and a sealable base is used for this test and overcomes problems encountered when using standard flower pots.
A special vessel with a rigid extension collar and a sealable base is used for this test and overcomes problems encountered when using standard flower pots.
The effects of newly available peat amendments – namely peat fibre and coarse peat particles – were determined, and their possible contribution to the development of nursery stock media is discussed.
