Bu araştırma, Diyarbakır ili Çınar ilçesi tarım topraklarının farklı kullanım koşullarının toprağın fiziksel özelliklerine etkisini belirlemek amacıyla yapılmıştır. Bu amaçla üç farklı şekilde kullanılan (kuru, mera, sulu) tarım alanlarının her birinde 5 örnek olmak üzere toplam 15 noktadan örnek alınmıştır. Toprak örneklerinde tekstür, pH, EC, kireç, organik madde, kütle yoğunluğu, hidrolik iletkenlik ve agregat stabilitesi analizleri yapılmıştır. Elde edilen bulgulara göre bölge topraklarının tekstür bakımından ağır bünyeli, organik madde içeriği yönünden toprak işlemeli tarım yapılan kuru ve sulu tarım alanlarından alınan toprak örneklerinde yetersiz, mera alanlarından alınan toprak örneklerinde ise yeterli düzeyde olduğu tespit edilmiştir. Toprak örneklerinin organik madde içeriği, hidrolik iletkenlik ve pH bakımından kuru ve sulu tarım alanları arasında belirgin bir fark bulunmazken, mera alanlarından alınan örnekler arasında önemli farklar bulunmuştur. Toprakların pH değerleri hafif alkalin ve alkalin olup, bilinçsiz gübreleme ve sulama uygulamaları zamanla yöre topraklarında yüksek pH sorunu oluşturabilir. Ayrıca, toprakların kullanım durumları ile porozite, kütle yoğunluğu ve agregat stabilitesi arasında önemli ilişkiler belirlenmiştir.
This research was conducted in order to determine the effects of the different conditions of use of agricultural land in Diyarbakır or Chinar district on the physical characteristics of the land. For this purpose, a sample was taken from a total of 15 points, including 5 samples, in each of the three different ways used (dry, myrtle, water) agricultural fields. In soil samples, texture, pH, EC, cranberries, organic substances, mass intensity, hydraulic conductivity and aggregate stability are analysed. According to the findings obtained, the territory of the soil has been found to be inadequate in the land samples taken from dry and water agricultural areas of the soil processed agriculture in terms of texture, organic material content, and in the land samples taken from the soil areas are inadequate. While there is no distinct difference between land samples in terms of organic substance content, hydraulic conductivity and pH, such and water agricultural areas have found significant differences between samples taken from land areas. The pH values of the soil are lightly alkaline and alkaline, and unconscious fertilization and irrigation applications may cause a high pH problem in the local soil over time. Also, significant relationships between the conditions of use of the soil and porosity, mass intensity and aggregate stability have been established.
This research was carried out to determine the effect of different usage conditions of agricultural areas on physical properties of soil in Çınar district of Diyarbakır province. For this purpose, a total of 15 points were taken as 5 samples from each of the agricultural areas used in three different ways (dry, pastureland, irrigated). Texture, pH, EC, lime, organic matter, bulk density, hydraulic conductivity and aggregate stability were analyzed in soil samples. According to the findings, it was found that the region is heavily textured in terms of textures, and that the irrigated and dry agriculture areas of the cultivated agriculture were sufficient in terms of organic matter. While there was no difference between the organic and organic matter content of the soils, hydraulic conductivity and pH, there was no significant difference between dry and watery sampling points. Since the pH values of the soils are determined at the level of alkaline and alkaline levels, it can be problematic in time. Significant differences have been achieved between the use of soils and porosity, bulk density and aggregate stability.
