چکیده
A study was designed to evaluate the micronutrients status of soils of district Palandri, Azad Kashmir and to correlate the micronutrients with Physico-chemical characteristics of soil as well as to categorize the soils as high, medium and low in Cu, Zn, Fe, Mn and HWS B. Soil samples were collected from thirty wheat fields and thirty apple orchard soils during 2003. None of the soil sample was low in Cu, Mn and Fe contents. Zn was low in 20% wheat fields and 17% apple orchard soils while HWS B was low in 53 and 40% in wheat and orchard soils, respectively. The pH was negatively correlated with all micronutrients (Cu, Fe, Mn, Zn) while organic matter was positively correlated with all nutrients. Lime was negatively correlated with Zn, Fe, and Mn while positively correlated with Cu and B. The EC had positive correlation with B but negative with other micronutrients. Clay was positively correlated with all micronutrients except B.

Kashmir is located in a region where winter temperatures are very low. During the winter months, the temperature in Kashmir is often below 0⁰ C. Generally concrete placed in colder regions with the help of insulated forms as well as heaters to protect freshly mixed concrete against freezing. These practices try to incorporate unnecessary carbon and leads to an disagreeable carbon footprint. The...
