Title: Nutrient status in sugarcane growing soils of Haryana
Abstract: A soil survey was carried out in different sugarcane growing agro-climatic and edaphic regions of Haryana. Soil samples were collected and analyzed for physico-chemical properties. Soil pH, EC and organic carbon content ranged from 7.2–8.9, 0.09–1.10 dS m−1 and 0.25–0.97%, respectively across the regions. Available nitrogen, phosphorus (P2O5) and potassium (K2O) contents widely varied from 203.8–319.9, 19.6–96.6 and 121.4–582.4 kg ha−1, respectively. On the basis of nutrient index values, sugarcane growing soils of Haryana were categorized as deficient in available nitrogen, medium in P2O5 and high in K2O. DTPA-extractable Zn, Cu, Fe and Mn, were above the critical limits. A significant and positive correlation was found between organic carbon and available nitrogen (r=0.958*), P2O5 (r=0.597*), K2O (r=0.317*), and DTPA-extractable Zn (r=0.272*), Cu (r=0.272*), Fe (r=0.398*), and Mn (r=0.429*).
