摘要：Rainwater is not readily available to sandy loam Ghanaian ferric lixisols. In an attemptto increase water availability to Nyankpala ferric lixisols, their impervious iron pan was broken.Average yield (number of bags) of maize from ferric lexisol with ironpan broken was comparedwith that with iron pan unbroken. At an average annual rainfall of 64.125 to 106.775 mm forNyampkala, ferric lexisol with or without iron pan broken yielded similar quantity (20-25bgs/ha) ofmaize. Breaking of ironpan alone cannot increase water availability to Nyankpala ferric lixisols.Measures other than the breaking of iron pan are needed to increase water availability toferreiclesisols and similar soils. Research into sustainable technologies such as permanentamendments for increased soil water availability to ferric lixisol and similar soils is required.
