The objectives of this study were to analyze spatial structure of plant available micronutrients (Fe, Mn, Zn, Cu and B) in a large alluvial field (45 ha) under different crop patterns, map plant available micronutrients using geostatistical methods, and evaluate the factors and processes controlling the variability of micronutrients. A geostatistical sampling scheme was adopted, and 188 soil samples were taken from topsoils (0-20 cm) and subsoils (20-40 cm). DTPA extracted Cu showed the lowest variation (CV = 25.89% for topsoil and CV = 27.48% for subsoil), and Mn showed the highest variation (CV = 47.56% for topsoils and CV = 60.62% for subsoil). Geostatistical range varied from 102 in (Mn) to 406 in (B) in topsoil. Cupper had the shortest (80 m), and B had the longest range (408 m) in subsoils. Iron content showed the strongest spatial dependency, and the rest of the micronutrients studied exhibited a moderate spatial dependency based on nugget/sill ratio. Kriging maps of micronutrients revealed that Zn was deficient in the both topsoil and Subsoil of the whole field.eninfo:eu-repo/semantics/closedAccessgeostatisticskrigingmicronutrientssemivariogramArticle532101116Q4WOS:000268188300004Q4
