Tohum Yatağı Hazırlığında Tapan Kullanımının Topraktan CO2 Çıkışına Etkisi

Sera oluşumuna etkili gazların miktarı, insan aktiviteleri sonucu son yıllarda daha da artmıştır. Bu aktiviteler; endüstriyel, tarımsal ve fosil yakıt kullanımını içeren çalışmalardır. Tarımsal çalışmalarda üretilen sera gazları; CO2, NH4 ve N2O gazlarıdır. Bu gazlar içerisinde en fazla üretileni karbondioksit gazıdır. Toprak ekosistemi özelliklerine bağlı olarak topraktan salınan CO2 miktarı değişmektedir. Bu özelliklerden en önemlileri; toprak nemi, organik madde miktarı, toprak sıcaklığı ve toprağın havalandırılma derecesidir. Bu çalışmada sırasıyla; 0 (P0), 45 (P45) ve 60 (P60) kg ağırlığında tapanlar kullanılarak tohum yatağı hazırlanmıştır. Daha sonra, CO2 çıkışı ve toprak fiziksel özellikleri saptanmıştır. Elde edilen verilere göre; CO2 çıkışı; g m-2 h-1 olarak en çoktan aza doğru sırasıyla, tapansız P0 (0.104), P45 (0.043) ve P60 (0.037) uygulamaları birbirini izlemiştir. P0 ‘da (P

The Effect of Scrapper Use on Soil CO2 Emission during the Seedbed Preparation

As a result of human activities in recent years, the amount of greenhouse gases has increased dramatically. These are industrial and agricultural activities including the use of fossil fuels. Greenhouse gases produced in the agricultural activities are CO2, NH4, and N2O. CO2 is the most produced gas among the greenhouse gases. The amount of CO2 flux from soil varies depending on the soil ecosystem properties. The most important of these features are soil moisture, amount of organic matter, soil temperature, and the degree of soil aeration. In this study; a scrapper loaded with different weight of 0 (p0), 45 (P45) and 60 (P60) kilogram was used to prepare the seedbed. Then, the CO2 flux and soil physical properties were determined. According to the data obtained; CO2 flux (g.m-2.h-1) was 0.104, 0.043, and 0.037 for P0, P45,, and P60 respectively. P0 application produced more CO2 than the other two applications (P
