The Relationships Between Some Physico-chemical Properties and Nutrient Element Content of Paddy raised on Alluvial Land in Terme Region

The rice is one of the most important yields, which has valuable income for regional economy. In order to obtain optimum yield from rice cultivation, it should be known soil properties and nutrition content of land in which rice has been grown. Otherwise, it can be faced with deprivation of yield due to misuse or applications for rice land management. The objective of this study was to determine relationships between physic-chemical properties of soil located on alluvial lands and nutrient elements in Terme district of Samsun province. For this purpose, 64 soil samples collected from the study area was statistically evaluate. The clay, silt and sand content of soils varied between 19.8-67.7%, 14.5-32.0% and 1.7-65.7%, respectively. In addition, organic matter, salt, pH and lime content were found as 0,63-4,87%, 0.8-1.66 dS/m, 5.16-7.45 and 0.58-1.94, respectively. Moreover, micro and micro nutrient element contents were determined as 5.30-46.90 ppm, 45.0-635.0 ppm, 5.03-212.30 ppm, 6.11-91.32 ppm, 0.03-1.36 ppm, 3.83-15.90 ppm and 0.02-1.24 ppm for available P, exchangeable K, available Fe, Mn, Zn, Cu and B, respectively. It was found that there were significantly important relationships between clay content of soils and silt, sand, organic matter and Mn contents. Besides, there are significant relationships between sand and OM, and Mn content. Another significant relation was also determined between OM and Cu content. Other significant relations are between salt and K content; between pH and P, K, Mn and Cu contents, and between P content and K, Zn, Cu content and between K content and Zn, Cu content. Consequently, it should be given some suggestions such as application of fertilizers including P, K, Zn and B by taking into consideration of salinity level of soils and enrichment of organic matter in the paddy fields. Also, it was recommended to apply lime against potential Fe and Mn toxicity that may occur in the future, due to the fact that a large majority of soils have low pH values
