Abstract Unfavorable parameters in arid and semi arid soils such as high temperature and low rainfall havecreated the conditions that only plant species such as pistachio are able to grow Extensive cultivation ofpistachio and limitations of soil and water resources in Kerman Province have made precisionmanagement necessary That would lead to information about the important properties affecting the soilproductivity quality and health even for highly variable characteristics The objectives of this study wereto examine the spatial variability of some physical chemical nutritional and biological soil properties atthree depths 0 40 40 80 and 80 120 cm and to map these indicators in an area of about 5000 hectaresin pistachio orchards of Anar Rafsanjan Samples were taken based on a regular grid scheme at 117points in March 2011 Soil Characteristics including texture gypsum sodium adsorption ratio SAR respiration rate calcium carbonate equivalent organic matter and nutrients available phosphorus potassium iron copper and zinc were measured in all the samples or in 25 of the samples based ontheir importance Statistical analyses including descriptive statistics correlation analysis alsogeostatistical studies such as the evaluation of isotropy variography and kriging were performed and theirvalidity was tested All the properties were isotropic and exponential variogram was the best model fitted The spatial correlation of almost all the parameters was moderate and kriging could provide the mapsshowing their variability with a fairly good estimate For a better understanding of the variability of thecharacteristics with nugget effect postal maps and indicator kriging maps were created Kriging mapsvery well showed similar variability for correlated characteristics such as salinity and soil reaction Mapsalso show the low content of clay high salinity and sodium adsorption ratio high lime high pH low soilrespiration and the deficiency of available phosphorus iron zinc and copper in almost the whole area Besides the deficiency of available potassium in more than 80 percent and the deficiency of availablemanganese were recognized in more than 50 percent of the area In general the northern and westernparts of the study area have more favorable soil conditions This could be attributed to better managementand higher organic matter and clay content of the soil in such areas Although the soil salinity is higher inthe western part as compared to other areas nutrients concentration and respiration rate are also high Inconclusion precision management of soils based on the variability of soil properties is necessary in orderto help increase the production rate and keep the soil quality Keywords Spatial variability Soil quality Soil nutrients Salinity Alkalinity
