Toprak Özelliklerinin Tahmininde Sayısallaştırılmış Renk Parametrelerinin Kullanımı

Öz

Toprak biliminde toprağın doğal yapısını bozmadan, hızlı, güvenilir ve tekrarlanabilir analiz tekniklerinin geliştirilmesi sürdürülebilir tarım için gerekli olan güncel veri tabanlarının vakit kaybedilmeden oluşturulması için gereklidir. Bu çalışmanın amacı bozulmuş ve bozulmamış toprak örneklerinden kolorimetre ile elde edilen sayısallaştırılmış renk parametrelerinin toprak özelliklerini tahmin etme yeteneklerini araştırmak ve incelenen bozulmuş ve bozulmamış toprak örneklerindeki renk farklılıklarının nedenlerini ortaya koymaktır. Bu amaçla, koluviyal arazilerde gelişmiş dört farklı toprak profilinden horizon esasına göre alınmış yirmi dokuz toprak örneğinin bazı fiziksel ve kimyasal özellikleri laboratuarda belirlenmiş ve toprak profillerinin detaylı tanımlamaları arazide yapılmıştır. Her horizondan alınan bozulmuş ve bozulmamış agregat halindeki toprak örneklerinde kolorimetre yardımı ile renk okumaları yapılmış ve belirlenen L*, a* ve b* renk parametreleri yardımı ile kroma, hue ve renk farklılıkları hesaplanmıştır. Yapılan istatistiksel analizler bozulmuş ve bozulmamış örneklerin renklerinin birbirlerinden önemli derecede farklı olduklarını göstermiştir P

Use of Quantified Color Parameters in Estimation of Soil Properties

Abstract

Development of fast, reliable, and repeatable soil analyses techniques that causes minimum disturbance soil materials are required to create soil data bases that are needed to achieve sustainable agriculture. The aims of this study were to; i. investigate the ability of soil color parameters obtained by chromameter measurement of disturbed and undisturbed soil samples to estimate soil characteristics, and ii. explain the reasons of color difference observed between disturbed and undisturbed soil samples. Thirty nine soil samples collected from each horizon of four soil profiles developed in colluviums. Physical and chemical properties of soil samples were analyzed in the laboratory, and detailed descriptions of soil profiles were performed in the field. Chroma, hue and color differences were calculated from chromameter measured soil color parameters for both disturbed and undisturbed soil samples of each soil horizon. Color of disturbed and undisturbed soil samples were significantly different from each other P
