Abstract
In present study, geostatistical techniques were applied to assess the spatial variability of DTPA-extractable micronutrients which are named heavy metals as chemistry such as; iron (Fe), copper (Cu), manganese (Mn) and zinc (Zn) in the non-tillaged layer in Ordu province- Altinordu district, Black sea region, Eastern part of Turkey. Study area was approximately 40095.8 ha where was divided into grids with 2500 x 2500 m spacing with including 66 sampling points from 0-0.2 m in depth. Soil reaction (pH) was the least variable property while electrical conductivity (EC) was the most variable. While the highest nugget effect occurred for Ext-Cu with moderate spatial dependence, the lowest for Ext-Mn with strong spatial dependence. The greatest range of influence (17424 m) occurred for Ext-Cu and the least range (692 m) for Ext-Zn.
在本研究中，应用地统计学技术评估了DTPA可提取微量营养素的空间变异性，这些微量营养素被命名为重金属，如：；土耳其东部黑海地区奥尔杜省-阿尔廷杜区未耕作层中的铁（Fe）、铜（Cu）、锰（Mn）和锌（Zn）。研究区域面积约为40095.8公顷，分为2500 x 2500米的网格，包括0-0.2米深度的66个采样点。土壤反应（pH）的变化最小，而电导率（EC）的变化最大。而具有中等空间依赖性的Ext-Cu出现最高的熔核效应，而具有强烈空间依赖的Ext-Mn出现最低的熔核效果。Ext-Cu的影响范围最大（17424m），Ext-Zn的影响范围最小（692m）。
