Abstract

Analysis of one hundred twenty five each of surface and sub-surface soil samples from five land use system (LUS) viz., Agriculture (A), Horticulture (H), Agri–horticulture (AH), Ravines (R) and Forest (F) under alluvial soils of Gwalior Chambal division of Madhya Pradesh indicate that the different land use system, maximum organic carbon content in surface and sub-surface was recorded in forest whereas minimum in ravines areas. Bulk density was decrease in natural forest and Agri-horticulture systems. DTPA extractable ZN, Fe and Mn were higher in surface soil as compared to sub surface soil in all LUS whereas Cu in some LUS. Maximum soil samples was deficient in available Zn in agriculture followed by ravines land use system whereas forest land use system show sufficient content of available zinc in surface soils. All samples of different land use system were found to be sufficient in available Cu and Mn. In case of available Fe, minimum soils samples were found deficient in forest whereas maximum in ravines area.

Conclusion

The present study revealed a picture on the influence of different land use systems (LUS) on the available micronutrient cations status and physico-chemical properties of the soils of Gwalior Chambal region of Madhya Pradesh. It has been observed that forest and agri-horticulture land exhibited better status in most of the micronutrient status as well as soil parameters than the other land use system. The mean bulk density values of the studied soils were found higher in uncultivated LUS indicated more soil compaction in uncultivated LUS resulting unfavorable soil condition. Considering the forest land as benchmark, the inferiority of soils under agricultural activity is visible in the present investigation. Thus, initiation of judicious and location specific soil management practices becomes an important step in order to maintain the soil health in a sustainable basis.
