Abstract:

An investigation was carried out to determine the status of two micro-minerals (iron and manganese) concentrations in soil and forage in the semi-arid region of Punjab, Pakistan. Soil and forage samples were taken six times in a year and in every month during summer and winter from two different sites of Sargodha, referred to as feeding sites where animals fed round the year to fulfillment of their mineral requirements. Four forage and soil types were collected from each of the two sites during each sampling. Results showed that soil Fe ranged from 0.22 to 8.12 mg/kg on feeding site I and II, being lower at site I and higher at site II. Fe concentration in forage ranged from 0.61 to 99.6 mg/kg in summer and 0.65 to 68.8 mg/kg in winter, across all sampling periods of collection of samples. Overall, higher values of forage Fe were found in summer than that of winter, anticipating the Fe need in the form of supplementation for grazing ruminants. Soil Mn ranged from 0.12 to 3.86 mg/kg in feeding place II and I, respectively and forage Mn level ranged from 3.96 to 28.7 mg/kg during all plant harvesting periods, being higher in summer than that in winter, respectively, indicating the warranted need of supplementation particularly in winter to prevent the complications caused as a result of deficiency of this element for grazing animals.
