abstract
Four blocks were randomly selected from each district. Samples of soil forage and blood serum of sheep in North Eastern Agro Climatic Zone of Tamil Nadu (Kanchipuram, Thiruvallur, Thiruvannamalai, Vellore and Villupuram). The samples were collected and analysed for different macro (Ca, P, and Mg) and micro (Zn, Cu and Fe) mineral contents to establish the mineral correlation among soil, forage and animals. The macro and micro mineral contents in soils of different (study area) districts were higher than their respective critical levels. Similarly, in forage all the mineral values were above critical level except magnesium lower than the critical value in all the districts and the copper lower than the critical level in Villupuram districts. The study also revealed the serum mineral values above the critical levels in all the districts and significant variation of minerals were observed except Zn and Fe. No significant correlation was observed between soil – plant relationship with respect to macro and micro minerals. Soil – animal relationship revealed highly significant negative (P≤0.01) correlation for calcium, zinc and copper and significant negative correlation (P≤0.05) correlation for iron and phosphorus. Plant – animal relationship revealed a highly significant negative correlation for Ca and Cu. Zinc had highly significant (P≤0.01) positive correlation. No significant correlation between soil-plant, soil-animal and plant – animal was observed for magnesium level. However, further, studies should need to get the clear idea about soil-plant-animal relationship.
