tailieunhanh - Comparing tillage techniques by using a new infiltration method

A one-year field trial in Italy was carried out for comparing tillage systems such as 50 cm chiselling (CH), 40 cm plow-till (PT40) and 20 cm plow-till (PT20) according to results of a new developed infiltration method. | Tr.

Ponded infiltration rates were measured to obtain the field saturated hydraulic conductivity (Kfs) using single ring infiltrometers on six dates with six replications in three sites on a sandy clayey loam soil. In both PT20 and CH plots, K after tillage increased temporarily to a value of about 4 and 9 times greater than that observed fs before tillage, respectively. However, late in the season, it tended to be not significantly different from the one before tillage for both. In PT40 plot, K remained relatively constant during the year except May. At the end of the year, PT40 had the greatest K fs fs and CH had the lowest. As a result, it was found that the tillage technique used does not have appreciable effect on the K for this type of soil. Although fs tillage recreates transmission pores in increasing K , such pores were temporary, and tillage-created cracks may have collapsed fs within the season as a result of raindrop impact and wetting-drying cycles. Toprak İşleme Tekniklerinin Yeni Bir İnfiltrasyon Yönteminin Kullanımı ile Karşılaştırılması Özet: 50 cm derinliğindeki çizelin (CH), 40 cm (PT40) ve 20 cm derinliğindeki pulluk (PT20) gibi çeşitli toprak işleme tekniklerini yeni geliştirilen tek silindirli infiltrasyon testi sonuçlarına göre karşılaştırmak amacıyla İtalya’da bir yıllık bir arazi denemesi gerçekleştirilmiştir. Doygun hidrolik iletkenlik ( K ) 6 ayrı tarihte 6 yinelemeli olarak 3 ayrı konuda tek silindirli infiltrometreler fs kullanılarak kumlu killi tınlı topraklar üzerinde .
