      A field experiment with winter wheat (Triticum aestivum L.) was conducted on a silt loam calcaric endorusti-ustic Cambosols derived from the Yellow River alluvial deposits in Henan, China, from 2001 to 2002 to evaluate N recovery and agronomic performance of different mineral coated fertilizers (MiCFs) compared to normal urea used in wheat cropping systems under field conditions. Five treatments, including CK (check, no N fertilizer), urea and three different MiCFs at an equivalent N application rate were established in a randomized complete block design. N release from MiCFs in soil was more synchronous with the N requirement of wheat throughout the growth stages than that from urea, with grain yield of the MiCF treatments significantly higher (P < 0.05) than that of the treatment urea. Correspondingly, the N recovery rate was greater for all MiCFs compared to urea, increasing from 32.8% up to 50.1%. Due to its high recovery and low cost. use of the mineral coated N fertilizers was recommended instead of the polymer coated N fertilizers.
Key Words:  mineral coated fertilizer, N recovery, urea, winter wheat
