Abstract
Leonardit toprağın fiziksel, kimyasal ve biyolojik aktivitesini artıran ve yüksek oranda humik ve fulvik asit içeren, toprağa uygulandığında toprakta alınamaz halde bulunan bitki besin elementlerinin bitkiler tarafından alınabilir hale geçmesini sağlayan organik bir materyaldir. Ülkemizde organik toprak düzenleyiciler grubunda yer alan leonarditler oluşum şartlarına göre farklı kalitelerde bulunabilmektedir. Bu nedenle, ülkemizde kullanılan yerli ve yabancı kaynaklı 28 adet leonardite ait bazı fiziksel ve kimyasal analizler Resmi Gazetenin, 20.03.2014 tarih ve 28956 sayılı Yönetmeliğinde belirtilen analiz yöntemlerine göre yapılmış ve değerlendirilmiştir. Yapılan analizler sonucunda leonarditlerin farklı fiziksel ve kimyasal özelliklere (pH, EC, organik madde, toplam humik+fulvik asit, C/N, KDK, makro ve mikro bitki besin elementleri ve ağır metal) içeriklerine sahip olduğu belirlenmiştir. Ayrıca leonardit örneklerinin % 71.42’si (20 adet) ülkemizde kullanılan ilgili yönetmeliğin tolerans sınırları dışında bulunmuştur.
Leonardite is an organic structure which increases physical, chemical and biological activities of the soil and contains a high proportion of humic and fulvic acid, enabling the plant to absorbe the plant nutrients which are insoluble in the soil when applied to the soil. Leonardites which are in the group of organic soil conditioners in our country are in different qualities according to the formation their conditions. For this aim, some physical and chemical analyses which belong to 28 leonardites with domestic and foreign origins used in our country have been done according to the analysis methods based on the Regulation of Official Gazette with the number 28956 and with the date March, 29, 2014. As a result of the analysis, it has been found that leonardites have different physical and chemical properties (pH, EC, organic matter (%), total humic+fulvic acid (%) , C/N, CEC (me 100 gr-1 ), macroelements (%), microelements (mg kg-1 ) and heavy metal (mg kg-1 ) . According to the obtained data, 71.42 % of the leonardite samples (20) were determined to be outside the tolerance limits of the releveant regulation used in our country
