Konya ovası'nda yüzeyaltı drenajın nitrat yıkanmasına etkisi

Bu çalışma yüzey altı drenajın nitrat yıkanmasına etkilerini belirlemek amacıyla yürütülmüştür. Konya Ovasında Karkın yöresinde toplam 50 hektar alanı drene eden iki toplayıcı dren 4 yıl (1999-2001), Alemdar ve Dedemoğlu köylerinde ise 8 hektarlık alanı drene eden birer emici dren bir yıl izlenmiştir. Ayrıca Karkın çevresindeki 7 yer altı kuyusunun nitrat analizleri yapılmıştır. Drenaj sularında yüksek oranlara ulaşan nitrat yüklerine rastlanırken, yer altı kuyularından sadece birinde yüksek bir değere rastlanmış, diğerlerinde ise nitrat içerikleri 10 mg l-1 nin altında bulunmuştur.

Effect of subsurface draınage on nıtrat leachıng of ırrıgated areas in Konya plain

This study was conducted out to determine the effects of subsurface drainage system onto nitrate leaching in Konya plain. Drainage systems that drained 50 ha area were monitored four years (1999-2001), near Karkm township ve one year (1999) at Alemdar ve Dedemoglu villages 8 ha area in Konya. Further, groundwater were analyzed in seven deep well near the Karkm. The high nitrate load was found in drainage water but it was low in the ground water except one. Nitrate concentration in well was found under 10 mg l-1.
