Değişik yöntemlerle ıslah edilen meralarda bazı toprak kalite özelliklerinin değişimi

Bu çalışma; farklı yöntemler uygulanarak ıslah edilen mera alanında ıslah uygulamalarının bazı toprak kalite özelliklerine etkisini belirlemek amacıyla yapılmıştır. Bu amaçla, 2008 ve 2009 yılları Mayıs ayının ikinci haftasında 5 farklı ıslah yöntemi uygulanan mera alanından ve herbir ıslah uygulama alanının sekiz farklı yerinden 0–15 ve 15–30 cm derinliklerinden toprak örnekleri alınmıştır. Alınan toprak örneklerinde; toprak reaksiyonu, toprak tuzluluğu, kireç içeriği, toplam karbon, toplam azot, agregat stabilitesi, kuru hacim ağırlığı, tane yoğunluğu, katalaz enzim aktivitesi, üreaz enzim aktivitesi ve mezofil aerobik mikroorganizma sayıları tekrarlanan ölçümlerle incelenmiştir. Elde edilen verilerin istatistik analizlerine göre ıslah uygulamalarının; toprak reaksiyonu, toprak tuzluluğu, kireç yüzdesi, toplam azot, agregat stabilitesi, katalaz enzim aktivitesi ve mezofil mikroorganizma sayıları özelliklerine etkisinin önemli düzeyde (P

Change of some soil quality characteristics under different rasture reclamation methods of rangelands

The present study was conducted to investigate the effects of different pasture reclamation methods on soil characteristics. For this purpose, soil samples were taken from 0–15 and 15–30 cm depths of the pasture lands subjected to 5 different reclamation processes from 8 different locations of each process during the second week of May of 2008 and 2009. Soil reaction, soil salinity, lime content, total carbon, total nitrogen, aggregate stability, bulk density, particle density, catalase and urease enzyme activities and mesophyllic aerobic microorganism count tests were carried out on soil samples for two years. Effects of reclamation processes on soil reaction, soil salinity, lime content, total nitrogen, aggregate stability, catalase enzyme activity and mesophyllic microorganism counts found to be significant at P
