Two orthic profiles, widely separated geographically, of each of four parent materials—lacustrine, alluvial–lacustrine, glacial till, and Aeolian—were selected at undisturbed sites within each of the Brown, Dark Brown, and Thin Black soil zones. Material from the Ah and Bm horizons was subjected to solvent extraction, and for each sample the total organic carbon of seven different fractions was determined.The efficiency of the procedure in extracting humus carbon decreased as the total carbon content of the soil increased. Total organic matter, the first humic acid fraction, and the combined total of the three humic acid fractions showed significant differences between soil zones. The only significant separation between all four parent materials was made by the alcohol-benzene fraction. Other parent material separations were possible only following the summation of data of several fractions, such as the three humic acid fractions or the two fulvic acid fractions. A simplification of the procedure in case of soils of one Order and a modification to overcome the impeding effect of increased carbon content are requisite.

<p><strong>A</strong><strong>bstract</strong></p><p>Knowledge about the genesis and evolution of black soils in the Eastern Mediterranean is vital for sustainable land management as well as for revealing the current and past climate conditions that were decisive for their evolution and development. Hence, it is important to study this type of soil as it only occurs very rarely in the semi-arid region. Answers on the conditions of formation and type of paleoclimate that prevailed during its development can be found in the surrounding environment. In this study, the black soils that currently occur in the Eastern Mediterranean were analyzed in different bioclimatic zones and were found to genetically belong to two soil types: 1-Calcareous black soil (ProperRendzina-Typic Rendolls), 2-Hydromorphic black soil (Haploxerolls). The impact of the relief was obvious on both thickness of the solum and the mollic horizon. Proper Rendzina (Typic Rendolls) occurs on toe slopes and feet slopes, Para-Rendzina (Lithic Rendolls) on shoulders and Chernozems on a flat plain. Regarding the Rendzina, the color reflects the origin of the prevailing parent material from which they are derived: Proper Rendzina forms on limestone, chalk, sandstone, conglomerates, and claystone; Reddish Rendzina on Dolomite and hard limestone, and Grayish Rendzina on Serpentine. It was also found that the Hydromorphic black soils (Haploxerolls, Calcic Chernozems) only occur on calcic marl and lacustrine deposits under saturation conditions and bad drainage in the depressions that formed by the Dead Sea faults. The soil has a thick dark mollic horizon with a high content of organic matter.</p><p><strong>Keywords</strong>: semi-arid, black soil, Rendzina, Chernozems, eastern Mediterranean.</p><p> </p>

Evaluation Of Methods

Two Orthic Chernozemic profiles of each of four parent materials were selected at undisturbed sites within the Brown, Dark Brown, and Thin Black soil zones of southern Alberta. This constituted 24 profiles representing 12 Chernozemic soil series. Material from the Ah and Bm horizons was subjected to nine procedures for estimating total organic phosphorus.The data of this study generally substantiated the usefulness of a modified Kaila–Virtanen method for these soils. With some soils, such as those from the Brown soil zone and those developed from aeolian parent material, other methods gave similar results. Reproducible results were obtained with only four methods.The efficiency of estimation of some of the methods decreased as organic phosphorus content of the soil increased. This, together with several other observations, suggests that the organic phosphorus of soils cannot be measured quantitatively at present. Several of the comparisons between methods, however, will be useful for further qualitative work.

Radiocarbon dates were analyzed to assess Vertisols age around the world. They show an increase of radiocarbon age from mainly modern–3000 BP in 0–100 cm layer up to 10,000 BP at a depth 100–200 cm. Older dates reflect the age of parent material. The inversion of 14C dates seems to be a frequent phenomenon in Vertisols. A series of new dates of Vertisols from gilgai microhigh, microslope and microlow in the North Caucasus was done in order to understand the nature of this inversion. 14C age in the gilgai soil complex ranges from 70 ± 45 BP in the microlow to 5610 ± 180 BP in the microhigh. A trend of similar depths being younger in the microslope and microlow was found. We explain this by intensive humus rejuvenation in the microlows due to water downward flow. The older date in the microhigh represents the old humus horizon sheared laterally close to the surface and preserved by impermeable water regime. We explain inversions of 14C age-depth curves by the sampling procedures. In a narrow pit, genetically different parts of former gilgai could easily be as a genetically uniform soil profile. Because of this strong microvariability, Vertisols require sampling in a trench accounting for gilgai elements, even when gilgai are not obvious.

The Past

Soil is the layer of the earth's surface that comes from parent material which has undergone an advanced process. In the past, roof tiles came from clay that was molded and heated to dry. Therefore, for selecting quality tile, it must be in accordance with the specified soil. Some of the soils that have been selected from tile making are clay clay, red soil, black soil, brown soil (kobih), yellow soil (kombung). while good soil is of course land that can meet the maker of his needs. Some of the criteria for good and quality tile, for example in terms of strength, precision, non-cracking, and yellow ivory. The decision support system is a method designed to assist users in making decisions and can also be used as a quality tile selection recommendation system for makers. This decision support system uses the Fuzzy ELETRE method as a process in determining the best soil type so that the results show that TA (combination of clay, brown (kobih), black) and TC (combination of clay, yellow, black) dominates more than TB (combination). loam, red, black).
