Delineation work was undertaken to evaluate the status of micronutrients in mixed red and black soils of Rewa district (Madhya Pradesh). The district is spread between latitude-24º21'59.9'' N to 24º48'40.9'' N and longitude-81º09'21.8'' E to 82º02'02.2'' E. The mean value of pH, electrical conductivity, organic carbon and CaCO3 in soil were 7.45, 0.21 dSm -1 , 5.03 g kg -1 and 2.83 g kg -1 , respectively. The average Zn, Cu, Fe, Mn and B contents were observed as 0.69, 1.17, 20.87, 14.41 and 1.34 mg kg -1 , respectively. The available Zn, Cu, Fe and Mn showed negative correlation with soil pH, whereas available boron content exhibited positive correlation. Zinc and boron showed positive and significant correlation with organic carbon. Similarly, Zn, Mn and B were found negatively and significant correlation with CaCO3. The results of the study indicated that zinc (Zn : 55.9 %) and iron (Fe: 2.0 %) deficiency are the major disorders in mixed red and black soils of Rewa district of Madhya Pradesh, India.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
