From each block 25 sites were selected for sampling. Results indicated that the amount of water soluble, exchangeable and non- exchangeable, lattice and total –K of Morena district: ranged from 4.2 – 19.2, 34.0-186.0, 291.3-1628.1 with the mean value of 9.6, 101.1 and 820.0 mg kg -1 respectively. The amount of lattice and total-K of Morena district; ranged from 0.42-1.95 and 0.45-2.11% with the mean value of 1.08 and 1.17%, respectively. Electrical conductivity of soil showed negative relationship with all the forms of potassium but they are not reaching the level of significant. In general, organic carbon content of the soils of showed positive relationship with all the forms of potassium. The coefficient of correlation of organic carbon with water soluble, (r= 0.586**), exchangeable (r= 0.615**), non-exchangeable –K (r=0.579**), lattice –K (r=0.482**) and total K (r=0.500**) were observed which were significant at higher level (1%). Highly significant and negative correlations were observed between different forms of potassium and sand particles content of the soils. In general, clay particles of the soil showed positively and significantly relationships with all the forms of potassium. A highly significant (1% level) and positive relationships were observed between different forms of K, these relationship indicated that there existed an equilibrium between these forms of K and depletion of one is instantly replenished by one or more of the other forms of K. Key words : Forms of potassium, relationship, status of soil Introduction equilibrium are markedly affected when The major crops of the investigate applied soil solutions K is either taken up area are paddy, sesame, pearl millet and by plants or leached into the lower soil sorghum in kharif whereas mustard, wheat horizons or converted into unavailable and potato in Rabi. Under intensive forms consequently. Non- exchangeable K cultivation, readily available exchangeable is released as exchangeable forms when K is removed by crop. This is followed by levels if exchangeable and solution K are further release of exchangeable K from decreased by plant uptake and leaching. non- exchangeable forms. The dynamic The dynamics of potassium in soil depends 16 TECHNOFAME- A Journal of Multidisciplinary Advance Research on the magnitude of equilibrium among 1) was found in Beelpur and Nidhan village various forms which has relationship with of Ambah and Joura Blocks respectively. physico-chemical properties of soil. Organic carbon status of Material and methods investigated area was found in the range of Random soil samples from 0-15cm 1.7-7.9 g kg -1 under different villages with depth were collected from 15 different the average value of 3.8 g kg -1. It is clear villages (10 soil samples / village) of five from the results, that average value of Blocks namely Morena, Ambah, Porsa, organic carbon content in all the villages of Joura and Kailaras of Morena district. The Morena district were observed in low sample were processed and passed through category (<5.0 g kg -1).

Similar results have been reported found in Visangpura and Bijlipura village in the past [9, 12]. of Joura and Porsa block. Result on the same line with different soil types have Non exchangeable K status of also been reported earlier [10, 12] . Morena district (Table -2) was found in the range of 291.3 – 1628.1 mg kg -1 under It is clear from Table-3 that the different village with the average value of exchangeable K showed significant and 820.0 mg kg -1 . Average maximum value positive correlation with organic carbon of non exchangeable -K (1003.6 mg kg -1) content and clay particles of the soils. was observed in Gidoli village of Porsa Which might be due to the fact that with block whereas minimum value (570.2 mg increase in organic matter in soils, the kg -1) found in Visangpura village of Joura clay-humus complex becomes more active block which is contributed 7.00 percent thereby providing more exchangeable sites of the total K content of the district. These and access to K. these results are in findings confirm the work of many others agreement with the findings of many [5, 11, 13, 15 &16] [2, 9] . others . Lattice- K status of Morena district Negative and significant was found in the range of 0.42 – 1.95 % coefficients of correlation of sand particles under different village with the average were observed with all the forms of K in value of 1.08 percent.

This type of value of lattice -K (1.30%) was observed relationship between sand and forms of in Bhatpura village of Kailaras block potassium was also observed by earlier [1, 7, 13 &14] whereas minimum value (0.94%) was workers .
