Growing of plants like tomato can be solution for coping with soil salinity. For this purpose, response of tomato to salinity has been tested in the early growth stages. Characteristics of germination (percentage and period; length and fresh-dry weight of radicle and hypcotyl) and seedling (length and fresh-dry weight of root, shoot and whole plant; leaf number and area based on Relative Growth Rate); Na+ and K+ content of leaf; K+/Na+ rate of leaf has been studied at the 0, 50, 100 and 150 mM NaCl levels. Thus, it determined that tomato can be indicator for agricultural cultivation at the salinity environments at the early growth stages.

Amik Lake has a higher level of degradation and mineralization than the other two lakes. Therefore, the high pH and salt value of the plain soil caused the proportions of calcium carbonate and active crime in the soil to increase, the organic matter level and the altitude to be low. The salinity of the soil is less in the Golbasi Lakes. It is related to geological location and land use as it is related to less degradation of area land. Gavur Lake caused more soil organic matter content to remain under water due to inadequate drainage conditions. The presence of limestone and serpentine as a dominant cation of convertible calcium and magnesium in the Eastern Mediterranean Region, the material transported by the surface waters of the rains falling to the region was considered as the main factor in increasing the concentrations of calcium and magnesium in the lake a...

The relationships between total microorganism counts and some soil characteristics of 3 different wetland lands in the Eastern Mediterranean region have been determined. As a result of the biological analyzes carried out on three different wetland soils; the highest number of total actinomycetes were found from microorganisms in the field soils, this is followed by the moment of total algae, total bacteria and the total fungi. It was first observed that microbial activity in the soil of Amik Lake, where the most degradation was caused by drying, decreased. In the same area, the total amount of fungi, bacteria, algae and actinomycetes was found to be the lowest in this study. It has been found that the total amount of fungi, bacteria and ac...

Quantitative clay analysis was performed by means of factorial method to determine clay mineral contents and distributions of soils. Clay mineralogy analysis was domination of smectite mineral soils, and was followed by palygorskite, illite, vermiculite and kaolinite, respectively. The higher calcium level in the soil and the basicity of the soil pH make smectite the predominant mineral, thus providing favorable conditions. The presence of palygorskite mineral in all soils indicates that the richness of calcium and magnesium in the basement lake basins is a favorable condition for this mineral to maintain its stability.

However, this study attempts to manifest the practical utilization of analytical data for determining the susceptibility to soil erosion. The data obtained involve the determination of clay mineral properties, calcium/magnesium ratios, and free aluminum (Al) and iron (Fe) oxides on structure stability, and hydraulic conductivity properties. Nine representative soil pedons developed on serpentine, limestone, and basalt parent materials were selected for the study. The soils were initially grouped into 3 according to their structural stability values. Group 1 soils had the lowest structural stability, highest smectite/kaolinite ratios, and shallow profile depths with the lowest Ca2+/Mg2+ ratios.

The total contents of heavy metals nickel (Ni), chromium (Cr), copper (Cu) and zinc (Zn) in soil pollution parameters were determined. For this purpose, the tri-acid digestion method was applied to the soil and an inductively coupled plasma device was used. According to the data obtained, the total concentrations of Ni, Cr, Cu and Zn were changed between 49.04-1954.094 mg kg -1 , 36.65-1630.609 mg kg -1 , 7.02-48.776 mg kg -1 and 7.607-34.788 mg kg -1 respectively.

Falcon) seedlings. Excess Mn as 100 and 200 mg Mn L-1 decreased all the growth parameters according to control plants. Manganese accumulation significantly increased in the parts of the seedlings with increasing amounts of Mn. A positive interaction was observed between 50 mg L-1 Mn and uptake of all elements except Zn content in root, shoots and leafs and Ca content in leaf of in seedlings and growth. Elevated Mn as 100 and 200 mg L-1 were commonly limited growth and uptake macro-micro elements by plant parts. Effects of Mn in low concentrations as 50 mg L-1 dose of Mn was stimulate but Mn in excess levels as 100 and 200 mg L-1 was limited for tomato seedlings characteristics.

The findings showed that plant biomass significantly increased, but fruit yield was not affected with gyttja applications. On the other side, nitrogen applications at 140 mg kg-1 and 210 mg kg-1 doses significantly increased biomass and fruit weights. Among the soils formed on different parent materials, in case of plant morphological variations plant heights and biomass weights were highest in the basaltic soils while the highest fruit weight was measured for serpantine soils, and the highest harvested number of fruits were measured for limestone soils.

Various methods were used for isolating semectite and palygorskite minerals. While palygorskite and smectite were not succesfully separated soil samples, separation was achieved in Fatik limestone residue. While the length of palygorskite minerals was found to be 1.00-2.75 mm and the width 0.10-0.20 mm in limestone, the length and width of palygorskite minerals were found to be about 0.20-0.75 mm and 0.075mm, respectively, in soil samples. While Fatik limestone residue had a strong endothermic reaction at 170-210 °C, soil samples reacted only slightly at 150 °C only. Even though chemical analysis indicated that they were similar, DTA electron microscope data showed that palygorskite obtained from soil samples was structurally different from palyorskite obtained from residue. In light of the above data, it was determined that palygorskite from limestone was unstable in saline settling surrounding and dissolved in soil conditions and formed stable palygorskite in the present conditions.

Slowly available potassium content was determined by the HCl extraction method. Slowly available potassium was found at between 3 and 46 mg 100 g-1 at a depth of 0-15 cm, 1 and 33 mg 100 g-1 at a depth of 15-30 cm and 1 and 25 mg 100 g-1 at a depth of 30-45 cm. Slowly available potassium content decreased along with soil depth. Available potassium content also decreased with soil depth. A significance correlation (0.1%) was found between available potassium and slowly available potassium. It was concluded that the slowly available potassium of soils could indicate the need of fertilisation in samples 11 and 12 in a short time, and in samples 2, 3, 4, 5, 6, 7, 8, 9, 13 and 14 in 5-15 years. Slowly available potassium was sufficient in samples 1 and 10. The insufficiency of the slowly available potassium of plain soils indicated that it might be useful to check the potassium content of the soil at certain intervals.
