Araştırmada farklı domates hasat kalıntılarından
farklı sıcaklıklarda yakılmasıyla elde edilmiş biyokömürün, toprağın bazı
yarayışlı besin elementi konsantrasyonlarına etkisini incelemek amaçlanmıştır.
Bunun için domates sapları 500 ve 700 derecede 80 dakika süreyle yakılarak
biyokömür elde edilmiştir. Elde edilen biyokömürler, arazi koşullarında 50x50
cm ölçülerinde hazırlanan parsellere dekara 3 ton olacak şekilde uygulanmış ve
doğal koşullarda beklemeye bırakılmıştır. Uygulamadan 2 ay sonra, 1 er ay
aralıklarla 4 dönemde toprak örnekleri alınmış ve bu örneklerde bitkiye
yarayışlı ve/veya çözeltiye geçebilen besin elementleri analizleri yapılmıştır.
Elde edilen sonuçlara göre biyokömür uygulamalarının toprakların besin elementi
içeriklerini genelde etkilemediği, hatta bazı besin elementleri üzerinde
olumsuz etki yaptığı görülmüştür. Yakma sıcaklıklarının biyokömürün etkinliği
üzerine bir etkisi görülmemiştir.

Effects of tomato harvest residue derived biochars obtained from different pyrolysis temperature on periodical available nutrient concentrations of soils

Öz

The aim of this study was to investigate the effects of biochars obtained by pyrolysis of the tomato harvest residues at different temperatures on some available nutrient concentrations of soil. For this purpose, biochars were obtained by pyrolysis of the tomato harvest residues at 500 and 700° C for 80 minutes. The biochars were applied to the parcels prepared in 50x50 cm dimensions under field conditions to 3 tons per decare and they were left to stand in natural conditions. 2 months after the application, soil samples were taken in 4 periods at one-month intervals. In these examples, plant available and/or extractable nutrients were determined. According to the results, it was observed that biochar applications did not affect the nutrient concentrations of the soil and had a negative effect on some nutrients. The pyrolysis temperatures had no effect on the efficiency of biochar on soil nutrient concentration.
