Abstract

The aim of this study is to identify in the effects of aggregate size and intra-row compaction levels on soil carbon IV oxide-carbon (CO2-C) fluxes, bacterial and fungal populations in advancement period of wheat. A horizontal axis rotary tiller was used to componer two dissimilar mean weight diameters (MWD) by changing tractor forward speeds. Tractor forward speeds were 1.8 and 4.5 km h-1, however; intra-row compaction levels were: no compaction, 30 kPa and 60 kPa compaction. Statistically significant differences in fluxes of CO2-C, microbial inhabitants and penetration resistance (PR) were discovered at the both MWD and intra-row compaction levels. Maximum CO2-C fluxes and bacteria and fungi inhabitants were perceived at the plot which 12.75 mm MWD and no compaction, and the minimum rates were assigned at the plot which 17.87 mm MWD and 60 kPa intra-row compaction all of the evaluation periods. Rising intra-row compaction levels decreased soil CO2-C fluxes and microbial population, but increased penetration resistance.

Özet

Bu araştırmanın amacı, agregat büyüklüğü ve sıra üzeri sıkıştırma düzeylerinin buğday bitkisinin gelişim periyodu boyunca CO2 yayılımı, bakteri ve mantar popülasyonlarına olan etkilerini belirlemektir. Araştırmada, iki farklı ortalama ağırlık çap grubu elde edebilmek amacıyla yatay rotorlu toprak frezesi farklı traktör ilerleme hızlarında kullanılmıştır. Traktör ilerleme hızları olarak 1.8 ve 4.5 km h-1, sıra üzeri sıkıştırma düzeyleri olarak ise 0,30 ve 60 kPa sıkıştırma düzeylerinden yararlanılmıştır. Araştırma sonuçlarına göre, CO2 yayılımı, mikrobiyal popülasyon ve penetrasyon direnci üzerine hem ortalama ağırlıklı çap değerlerinin hem de sıra üzeri sıkıştırma düzeylerinin etkileri önemli bulunmuştur. Tüm ölçüm periyotlarında en yüksek CO2 yayılımı ile bakteri ve mantar popülasyonları; 12.75 mm ortalama ağırlıklı çap grubu ile sıkıştırmanın uygulanmadığı parsellerde gözlenirken, en düşük değerler; 17.87 mm ortalama ağırlıklı çap grubu ve 60 kPa sıkıştırma düzeyinin uygulandığı parsellerde elde edilmiştir. Sıra üzeri sıkıştırma düzeyindeki artış CO2 yayılımını ve mikrobiyal popülasyonu azaltmış, penetrasyon direncini ise artırmıştır.
