Soil aggregate stability is an ideal integrative soil quality indicator, but little known about the relevance of such indicator with depth for salt-affected soils. The objective this study was to determine and identify preponderant aggregation factors, both in topsoil subsoil horizons conditions. We conducted field investigations by describing profiles pedological pits collecting samples from d...

The rise of emerging contaminants in waters challenges the scientific community and water treatment stakeholders to design remediation techniques that are simple, practical, inexpensive, effective, environmentally friendly. Emerging include antibiotics, hormones, illicit drugs, endocrine disruptors, cosmetics, personal care products, pesticides, surfactants, industrial microplastics, nanopartic...

Human economic activity leads to removal of nutrients from the soil along with crop. Nutrients losses also occur because natural processes (erosion, leaching, etc.). It is necessary replenish missing use humate-containing organomineral fertilizers preserve fertility and increase productivity. The purpose this work study iron (III) phosphates interaction potassium humate obtain fertilizers. Meth...

It is a pleasure to be able to introduce this second Thematic Series on ‘organo-fluorine chemistry’ within the Beilstein Journal of Organic Chemistry. The series now embeds the subject firmly as a special interest area of the journal. The first series in 2008 presented contributions representing a wide range of organic fluorine chemistry [1-10] and this series continues that trend exploring the...

The organo-boron species formed from the reactions of boron atoms with acetylene in solid neon are investigated using matrix isolation infrared spectroscopy with isotopic substitutions as well as quantum chemical calculations. Besides the previously reported single C-H bond activation species, a cyclic-HBC2BH diboron species is formed via double C-H bond activation of acetylene. It is character...

Sequential density fractionation separated soil particles into ‘‘light’’ predominantly mineral-free organic matter vs. increasingly ‘‘heavy’’ organo-mineral particles in four soils of widely differing mineralogy. With increasing particle density C concentration decreased, implying that the soil organic matter (OM) accumulations were thinner. With thinner accumulations we saw evidence for both a...
