Soil organic matter (SOM), along with the rock weathering, originating from residues of animals, plants and microorganisms involved in soil formation evolution. The stability SOM could directly produce an effect on carbon sequestration. To elucidate characteristics karst areas at molecular structure level, this study, humic acids (HA), as major proxy SOM, were extracted, purified, ultra-filtrat...

This study was conducted to investigate direct short-term impact of vermicompost on some soil biological properties by monitoring changes after addition of vermicompost as compared to farmyard manure in an alkaline soil with high lime content from semiarid Mediterranean region of Turkey. For this purpose, mixtures of soil and organic fertilizers in different doses were incubated under greenhous...

The aim of this work is to model the occurrence and intensity of calcium carbonate loss in calcareous forest soils under Mediterranean conditions. We have used 193 Spanish forest soils found on limestone parent material considered highly calcareous materials. This data set came from FOREDAF, a database containing 2200 complete soil profiles and all of them covered by forest stands (mainly domin...

Although iron (Fe) is the fourth most abundant element in the Earth’s crust and upper mantle (lithosphere), Fe deficiency is among the most common plant micronutrient deficiencies. There are multiple contributing factors, but the most important for practical purposes in California orchard crops are those soil and water characteristics that cause lime-induced Fe chlorosis: soil and water with hi...

Phytoremediation is a promising method for remediation of heavy metals (HMs) contaminated environments. However, the main failures are the limited bioavailabilty of HMs such as lead (Pb) in the soil and/or suppressed plant growth in contaminated sites. These limitations specifically occur in semi-arid zone environments such as calcareous soils. Arbuscular mycorrhizal fungi (AMF) and plant growt...

Knowledge about the rates of pedogenic processes is essential to understand landscape development and history. It can be attained by the quantitative investigation of soil chronosequences. In this work, the development of Chromic Luvisols in the Mediterranean is addressed. The soils investigated are located on fi ve uplifted Pleistocene marine terraces in south-western Sicily, and have develope...
