DYNAMICS OF PH-VALUES IN BUFFERING RANGES OF SOILS IN PINUS
REGENERATION CULTURES UNDER NITROGENE EMMISSION INFLUENCE
Alojzy Kowalkowski, Halina Kopron
The research over possibilities for regeneration of pine woods in conditions the still lasting nitrogenous emission was realized on after-forestal terrains in 1995–2004, devastated by long-lasting strong nitrogenous emissions. The Scotch pine was planted to ploughed up furrows, in podzolic-rust soils produced from eolian sands, was as well the leveling potassium and phosphorous fertilization as apply in spring year 1996, after compensatory liming on autumn of 1995 year. The frequency occurrence of the value pHH2O in the buffered solution compartments in year seasons, in fertilization combinations, dynamics of course of profile depth line of value pH and the source of acidification the soils as well as dynamics acidity soils dependence on the moisture and some nutritious components easily migrating in soil solution were introduced on the basis of the gathered in years 19952004 data. In summing-up affirm that the ploughing up the furrows in soils altered the factorials by nitrogenous emissions the creation caused new the onegradient of depth profile of value the pH, differentiating in time, in ranges the interchangeable and clay buffered. The liming and mineral fertilization much increased this gradient.
