ÇAY ATIKLARININ BİTKİ YETİŞTİRME ORTAMI OLARAK KULLANILABİLME OLANAKLARI

Bu araştı rma, Çay işletmeleri Genel Müdürlüğü'nden sağlanan çay atıldan üzerinde yürütülmüştür. Araştı rmada kaba ve ince çay atıkları nın yanı sıra kompost ve zenginleştirilerek kompost yap ı lmış çay atıkları nın da bitki yetiştirme ortamı olarak kullarulabilme olanaklar ı saptamaya çal ışılmıştı r. Çay atıkları ilk başta hakim agregat büyilklüklerine göre 0-2.00 mm, 2.00-4.00 mm, 4.00-6.35 mm ve

THE USE POSSIBILITIES OF TEA WASTES AS A PLANT GROWTH MEDIUM

The research was carried out on tea wastes supplied from General Directorate of Tea Enterprises. The use possibilities of coarse, fine, composted and enriched composted tea wastes were as a plant growth medium studied. Tea wastes were seperated four different size fractions as 0-2.00 mm, 2.00-4.00 mm, 4.00-6.35mm and < 6.35 mm according to major agregate sizes and physical analysis were accomplished on those fractions. When the physical parameters were taken into consideration, 0-2.00 mm fraction of composted and enriched composted tea wastes were determined suitable as plant growth medium. However, tea wastes having physical problems seem to be usable as a plant growth medium, one can prepare their suitable mixtures with some materials such as peat and perlite, have higher easily available water content and higher aeration capacity or the use of different partide sizes in medium. In general, there was no problem in tea wastes in respect to the chemical characteristics. However, the pH values of composted and enriched composted tea wastes -are- high. Therefore, their pH should be adjusted to the appropriate values whiclı could not impede a controlled plant nutrition programme.
