Abstract:
Twenty soil samples were collected from different locations of Kakching district, Manipur for this experiment. All the investigated soil samples were acidic in nature with a mean value pH 4.98. There was wide variation of organic carbon content with a mean value of 16.76 g kg-1. The mean EC, Cation exchange capacity, available nitrogen, available potassium were 0.22 dSm-1, 14.01 [cmol(P+)kg- '], 212.66 kg ha-1, 114.75 kg ha-1, respectively. For the soil studied the amount of inorganic P fractions was in the order: Red-P> Fe-P> Al-P>Occl-P>Ca-P>Sal-P. Al-P and Fe-P were negatively correlated with pH (r = -0.446*) and (r=-0.447*) respectively. Saloid P was positively correlated with E.C. (r =0.512*) and CEC (r=0.456*) along with Red-P (r =0.555*). Occl-P was negatively correlated with available potassium (r = -0.505*) and positively and significantly correlated pH (r=0.583**)and CEC (r=0.577**). Ca-P was positively and significantly correlated with E.C (r = 0.523*), sand fraction (r=0.500*), clay fraction (r = 0.583**) and CEC (r = 0.605**). Sal-P was positively correlated with Ca-P and negatively correlated with Org-P (r=0.520* and -0.547*). Fe-P was positively correlated with Tot-P (r=0.540*) and Red-P with Ca-P (r=0.628**). Finally, the Tot-P was positively correlated with Org-P (r=0.882**).
