The addition of organic materials to the soil is important due to the sustainability of soil resources and their positive contribution to
soil properties. Many materials that are added to the soil as a source of organic matter have direct positive effects, such as storing
and storing carbon in the soil, as well as improving the physical, chemical and biological properties of the soil. Leonardite is one of
the most preferred organic soil conditioner, which is rich in humic acid and formed by oxidizing organic materials without being
affected by carbonization processes. Due to having high humic acid and carbon content, it has an important place in terms of soil
improvement and vegetative production. This study was carried out to determine the short-term effects of leonardite obtained from
two different sources ((Kayseri-Develi (DL) and Çanakkale-Yenice (YL)) on some properties of the soil with sandy loam (SL). For
this purpose, each leonardite type was mixed with sandy loam (SL) soil at the rate of five different doses (4%, 8%, 12%, 16%, 20%)
and they were incubated for three months. Soil organic matter (OM), soil reaction (pH), electrical conductivity (EC), lime content
(CaCO3), bulk density (dB), saturated hydraulic conductivity (Ks), aggregate stability (AS) and total porosity (P) of mixtures were
determined at the end of the incubation period to investigate the effects of leonardite. Leonardite applications increased EC (236%),
OM (213%), AS (50%) and P (11%) while decreased dB (10%) compared to control (p≤0.05). However, changes in other
parameters (pH, CaCO3, Ks) were not found significant statistically (p≥ 0.05). In general, it was determined that the effect of the
leonardite type on the parameters investigated was not significant (p≥ 0.05).

Organik materyaller toprakların sürdürülebilir olmasında önemli yer tutmaktadır. Toprağa organik madde kaynağı olarak ilave
edilen birçok materyal, karbonun toprakta tutulması ve depolanması gibi doğrudan olumlu etkisinin yanında toprağın fiziksel,
kimyasal ve biyolojik özelliklerini iyileştirici etkiye sahiptir. Organik toprak düzenleyici olarak en çok tercih edilen materyallerden
biri olan leonardit; organik maddelerin kömürleşme süreçlerinden etkilenmeyerek oksitlenmesiyle oluşan ve humik asitçe zengin
doğal bir materyaldir. Humik asitçe zengin olması ve yüksek karbon içeriği, toprak ıslahı ve bitkisel üretim açısından önemli bir yer
tutmaktadır. Bu çalışma, Kayseri-Develi (DL) ve Çanakkale-Yenice (YL) olmak üzere iki farklı bölgeden temin edilen leonarditin
kumlu tın (SL) bünyeye sahip toprağın bazı özeliklerine kısa süreli etkilerini tespit etmek amacıyla yapılmıştır. Bu amaçla leonardit
çeşitleri beş farklı dozda (%4, %8, %12, %16, %20) kumlu tın (SL) bünyeye sahip toprak ile karıştırılarak üç ay inkübe edilmiştir.
İnkübasyon süresi sonunda tüm uygulamalar için toprağın organik maddesi (OM), toprak reaksiyonu (pH), elektriksel iletkenliği
(EC), kireç içeriği (CaCO3), kuru hacim ağırlığı (dB), hidrolik iletkenliği (Ks), agregat stabilitesi (AS) ve boşluk hacmi (P) gibi
özellikleri belirlenerek leonarditlerin etkisi araştırılmıştır. Uygulanan dozlara bakılmaksızın her iki leonardit uygulamasıyla
kontrole göre EC (%236), OM (%213), AS (%50), P (%11) artarken, dB (%10) azalmıştır (p≤0.05). Buna rağmen diğer
parametrelerdeki değişimler (pH, CaCO3, Ks) istatistiksel olarak önemsiz bulunmuştur (p≥0.05). Genel olarak leonardit çeşidinin
incelenen parametreler üzerine etkisinin önemsiz (p≥0.05) olduğu tespit edilmiştir.
