Abstract:As an alluvial plain, the layers of soil profile are significantly complex in North China Plain, crop yields may be affected by soil profile texture pattern (SPTP), however, little information is available now on this issue. Based on the data of 152 soil profiles and wheat yield of 121 farm plots in 2008 and 2009, fuzzy c means (FCM) method and geostatistical model were used to study the quantitative relationship between wheat yield and SPTP. The results showed that there were mainly eight SPTPs in study area, which corresponded to the differences in wheat productivity. Among the eight SPTP patterns, wheat yield of the sand-sand-sand was the lowest, because sand soil showed poorly in retaining water and nutrients and its low nutrient contents, loam-clay-loam and loam-clay-clay were better patterns for high and stable yield. With highest level of wheat yields, sand-loam- loam, loam- loam-loam and loam-loam-clay were the best soils for fertility conditions. The influence of SPTP will be expressed when wheat yield below 7 050 kg/hm2.
