Possible Use of Leonardite Based Humate Sources as a Potential Organic Fertilizer
Although it is well known that humates are potential types of organic fertilizer,enough information is not available on the properties of humic substances originated from varied leonardite sources.Additionally,many studies have revealed the relationship between different humic substances and micronutrients availability in agricultural production.Evaluation of suitable humate composites as a potential organic fertilizer will improve micronutrient availability or prevent toxicity of these nutrients to the plants.This study aimed to determine some hormonal and chemical properties of the varied humates originated from different leonardite sources.For this aim,the leonardite substances were collected from Konya-Ilgin,Sivas-Kangal,K.Maras-Elbistan in Turkey.Some hormonal compositions such as gibberllin acid,salicylic acid,indole acetic acid,and chemical properties such as heavy metals of the substances were determined.As a result,the findings clearly revealed that characteristics of different humate materials as a potential organic fertilizer widely varied,especially depending on the leonardite sources collected from the varied regions.
