tailieunhanh - The effects of Glyphosate isopropylamine and Trifluralin on the carbon mineralization of olive tree soils

Glyphosate isopropylamine and trifluralin are herbicides widely used in Turkish agriculture. The recommended field dose (RFD) (480 g of active ingredient l-1 for both glyphosate and trifluralin) and 2 × RFD of these herbicides were added to the soil of olive trees (Olea europaea L., Oleaceae) growing on the Çukurova University Campus (Adana) under Mediterranean climate conditions in order to determine their effects on soil microbial activity as measured by carbon mineralization. | Turk J Agric For 31 (2007) 297-302 © TÜB‹TAK The Effects of Glyphosate Isopropylamine and Trifluralin on the Carbon Mineralization of Olive Tree Soils Feruze ESER, Hüsniye AKA SA⁄LIKER*, Cengiz DARICI Çukurova University, Faculty of Arts and Science, Department of Biology, 01330 Balcal›, Adana - TURKEY Received: Abstract: Glyphosate isopropylamine and trifluralin are herbicides widely used in Turkish agriculture. The recommended field dose -1 (RFD) (480 g of active ingredient l for both glyphosate and trifluralin) and 2 × RFD of these herbicides were added to the soil of olive trees (Olea europaea L., Oleaceae) growing on the Çukurova University Campus (Adana) under Mediterranean climate conditions in order to determine their effects on soil microbial activity as measured by carbon mineralization. Carbon mineralization of all samples was determined by the CO2 respiration method over 30 days (28 °C, constant moisture). When the RFD and 2 × RFD of glyphosate were compared to a control treatment with no herbicide, they significantly stimulated carbon mineralization at the end of the 30 days (P ). Based on these results, it is possible to conclude that soil microorganisms are capable of using glyphosate as a carbon source.

Bu herbisitlerin önerilen tarla dozu (hem glyphosate hem de trifluralin için 480 g l-1) ve bu dozun 2 kat› Akdeniz ikliminin etkisi alt›ndaki Çukurova Üniversitesi kampus (Adana) alan›nda yetifltirilen zeytin a¤ac› (Olea europaea L., Oleaceae) topra¤›na karbon mineralizasyon ölçümüyle toprak mikrobiyal aktivitesine etkilerini belirlemek amac›yla ilave edilmifltir. Tüm örneklerin C mineralizasyonu 30 gün boyunca (28 °C, sabit nem) CO2 .
