Abstract

Knowing wetting depth of soil is an important factor to determine the irrigation water amount depends on the development of plant root system in vegetation period. In this study, wetting depth of soil in corn grown area was estimated according to active soil layer, irrigation water amount, soil moisture change and field capacity using mathematical approach. In 40, 50, 60, 70, 80 and 90 cm soil layers, “wetting coefficients” and wetting depths for irrigation water amount of 900 m3 ha-1were determined as 1.62, 1.43, 1.26, 1.13, 1.02, and 109, 116, 109, 95, 84 cm, respectively. In the same soil layers, “wetting coefficients” and wetting depths for irrigation water amount of 950 m3 ha-1were determined as 1.71, 1.51, 1.33, 1.19, 1.07 and 119, 128, 122, 106, 94 cm, respectively. As a result, it was determined that basic factors effecting on wetting depth in irrigation were irrigation water amount and depth of active root zone.

Özet

Sulama suyu miktarının belirlenmesi için vejetasyon dönemindeki bitki kök sisteminin gelişimine bağlı olarak toprakta ıslanma derinliğinin bilinmesi önemli bir faktördür. Bu çalışmada, mısır yetiştirilen alandaki toprağın ıslanma derinliği, aktif topak katmanı, sulama suyu miktarı, topraktaki nem değişimi ve tarla kapasitesi değerlerine göre matematiksel yaklaşım kullanılarak hesaplanmıştır. Toprağın 40, 50, 60, 70 ve 80 cm’lik aktif toprak katmanlarında, 900 m3 ha-1 sulama suyu miktarı için sırasıyla “ıslanma katsayıları’’ 1.62, 1.43, 1.26, 1.13 ve 1.02, ıslanma derinlikleri ise 109, 116, 109, 95 ve 84 cm olarak hesaplanmıştır. Aynı toprak katmanlarında, 950 m3 ha-1 sulama suyu miktarında ise, sırasıyla “ıslanma katsayıları’’ 1.71, 1.51, 1.33, 1.19, 1.07, ıslanma derinlikleri () ise 119, 128, 122, 106 ve 94 cm olarak belirlenmiştir. Sonuç olarak, sulamada ıslanma derinliğine etki eden temel faktörlerin sulama suyu miktarı ve aktif kök bölgesi derinliğinin olduğu belirlenmiştir.
