Micronutrient Status of Soils under Legume Crops in Arid Region of Western Rajasthan, India

By B. K. Yadav


Abstract: To asses the micronutrient status of soils under legume crop in arid region of Western Rajasthan a study was conducted. A total of 652 soil samples (445 samples of rhizosphere and 207 samples of non-rhizosphere) from farmer’s field were collected and analyzed for DTPA-extractable micronutrient status and soil properties. Content of micronutrient was in order of Mn> Fe> Cu> Zn. The DTPA- Mn, Fe, Cu and Zn in 1 soils varied from 2.2 to 11.8, 2.5 to 6.5, 0.11 to 4.1 and 0.29 to 3.9 mg kg. The DTPA- Mn, Fe and Zn showed negative correlation with pH and EC of the soils, whereas Cu exhibited positive correlation with them. All the micronutrients showed positive correlation with organic carbon content of the soil. Key words: Micronutrient Legume crop Organic carbon Arid regio
