“…Soil reaction was determined by measuring with glass electrode pH-meter on saturated soil prepared with pure water, total salt was determined by measuring of electrical conductibility of water saturated soil with conductivity meter, available potassium was determined with the usage of 1 N NH 4 OAc (pH 7.0) as extract solution and potassium in extract was determined by measuring with flame photometry [17]. Field capacity held by water soil under its 1/3 atm and wilting point held by water soil under its 15 atm [18], sand, silt and clay fractions of soil were found according to hydrometer method [19], lime was determined with the usage of Scheibler Calcimeter [20], organic matter was determined according to modified Walkley-Black method [21]. Available phosphorus was determined with the method whose extract solution is 0.5 M NaHCO 3 (pH 8.5), which was developed by Olsen [22].…”

Surfactant is used as wetting agent, dispersant, emulsifier, foaming agent, bactericide in detergent, soap, herbicide and insecticides.The pollution from their residue in nature affects agricultural products as well. In this study was performed to determine the effects of anionic, cationic and nonionic surfactants on the dry weight of wheat (Triticum aestivum). This research was conducted as randomized split parcels with 3 repetetives in greenhouse. Surfactants were applied at 0, 180, 360, 540 and 720 mg kg -1 concentration after sowing, it was harvested on the 50 th day. Anionic surfactant caused to decrease the dry weight (p < 0.05) of wheat plant. While cationic surfactant caused to decrease the dry weight (p < 0.05), the application of nonionic surfactant did not.According to study results; anionic and cationic surfactants have a negative impact on the growth of plant roots of wheat. Therefore experiencing difficulties in the acquisition of plant nutrients can be attributed to a decrease in plant dry weight.

“…The digested soil solutions were diluted at 1 : 20 (v/v) and < 0.45 lm filtered (Sartorius, Göttingen, Germany), and then analyzed using inductively coupled plasma-mass spectrometry (ICP-MS, Agilent, Japan). Calcium carbonate content was determined according to the procedure of Martin and Reeve (1955). Field capacity was measured using a pressure plate at -10 kPa matric potential according to the procedure of Klute (1986).…”

A growth-chamber study was used to develop a zinc stable-isotope ( 67 Zn) tracing technique to directly measure the amount of soil-applied zinc (Zn) granular fertilizer taken up by durum wheat (Triticum durum L.) in four different soil types. The 67 Zn-tracer technique was then applied under field conditions at one site to test the ability of the method to measure the crop recovery of soilapplied Zn granular fertilizer ( 67 Zn). The technique was developed by comparing plants treated with nil Zn fertilizer to natural-abundance-Zn-coated fertilizer and 67 Zn-coated fertilizer with plant parts analyzed for Zn isotopic composition using inductively coupled plasma-mass spectrometry. Zinc-fertilizer recovery under growth-chamber conditions was inversely related to the concentration of labile Zn in soils, with the plants on the most Zn-deficient soils having the greatest amount of Zn derived from the added fertilizer. Zinc derived from fertilizer ranged from 0.3% (Luvisol) to 0.6% (Solonetz) to 13% (Calcisol) and 18% (Lixisol) for soils with DTPA-extractable Zn of 3.5-0.21 mg kg -1 . Across the experiments, fertilizer recovery was measurable but very low (< 1% of added fertilizer being recovered by durum wheat). The recovery of Zn added to the Luvisol was slightly higher in the field than in the glasshouse (but all < 0.1%). Using this stableisotope technique, it was possible to directly assess the supply of soil-applied Zn fertilizers to crop plants.

“…After transporting the soil samples to the laboratory, they were prepared for analysis by drying under shade, removing crop roots and stones by hand, smashing and sieving in 2 mm sieve. The soil physico-chemical properties were determined based on (in parentheses) as: particle size distribution (Bouyucos, 1951), pH in soil-water suspension by pH meter (Rowell, 1996), organic matter using wet oxidation method with K 2 Cr 2 O 7 (Walkey, 1946), lime content by volumetric calcimeter method (Martin and Reeve, 1965), and cation exchange capacity (CEC) by sodium saturation method (Chapman, 1965). Total Pb: the total Pb analyzed after digestion in hydrofluoric, nitric, sulphuric, and perchloric acids and Pb in solution was determined by Inductively Coupled Plasma (ICP) (Balraadjsing, 1974).…”

In this study, the relationship between some physico-chemical properties of soils and lead contamination in soil due to emission from industrial operations in Samsun province of Turkey was investigated. The extent of timely contamination was studied by comparing the obtained results with the results of the study conducted in the same region in 1998. An area of 225 km(2) (15 km x 15 km), which was divided into 1000 x 1000 m grid squares (16 lines in the east and south directions), was selected within the industrial area. The total of 256 grid points was obtained and soil samples were collected from three depths (0-5, 5-15, and 15-30 cm) of each grid center in 2004. The total Pb concentrations of soil samples were determined as 65.84-527.04 microg g(-1) at 0-5 cm in depth, 58.50 - 399.54 microg g(-1) at 5-15 cm in depth, and 44.65-330.07 microg g(-1) at 15-30 cm in depth. DTPA-extractable Pb concentrations of soils were found to be in the range of 1.52-9.03 microg g(-1), 0.54-7.09 microg g(-1), 0.19-6.13 microg g(-1) at 0-5, 5-15, and 15-30 cm depths, respectively. There were significant relationships between both total or DTPA-extractable Pb concentrations and selected physico-chemical properties of soil. According to enrichment factor (EF) values calculated from the total Pb concentrations, 11.3% of the study area (225 km(2)) was enriched with Pb in high level, but 77% of the area was in significant enrichment level with Pb. The average total and DTPA-extractable Pb concentrations increased as 11 and 13%, respectively in comparison with the results of 1998.
