Soil samples were collected from three different districts of Manipur under different land use system viz. Churachandpur (Jhum), Imphal east (Valley) and Senapati (Terrace) following the method of stratified multistage sampling. The aim of the work described here has been to assess the distribution of different forms of iron and aluminium in different land use system of Manipur. The value of KCl extractable Fe and Al was found to be highest In Jhum cultivation than Valley and Terrace cultivation. In Jhum cultivation the value of NH4OAc extractable Fe and Al observed the highest than in valley and terrace. Similarly in Jhum cultivation, the Pyrophosphate extractable Fe and Al showed higher value than the valley and terrace cultivation. Acid ammonium oxalate extractable Fe and Al showed higher values in Jhum cultivation in comparison with Valley and terrace cultivation. The value of Dithionite citrate bicarbonate extractable Fe in terrace cultivation was found to be the highest. On the other hand, the value of Dithionite citrate bicarbonate extractable Al was observed highest in Jhum cultivation.
