Background: The assessments of the available nutrient status of maize growing soils are essential to generate baseline information regarding efficiency of nutrient availability in order to improve yield and maintain soil health. The information generated would be useful for the subsequent research and developmental activities in these areas and shall guide in assessing the possible cause of low yield and quality of maize production. Methods: Fertility assessment of major maize growing soils for district Kupwara was carried out during 2016. Twenty (20) composite surface soil samples at representative sites were collected and investigated for the available nutrient status and chemical properties Result: The soils were slightly acidic to slightly alkaline in reaction (6.1-7.4). The soils of the study area were high in organic carbon content (0.7 to 1.4%), were low in soluble salts (0.11-0.35 dSm-1) and calcium carbonate content (0.08 to 0.15%). The available nitrogen, phosphorous and potassium were ranged from 295.24 to 510.00 kg ha-1, 10.03 to 20.36 kg ha-1, 131.00 to 165.30 kg/ha, respectively. The pH of the soils determined has a negative and significant correlation with available nitrogen (r = -0.915*) and phosphorous (r = -0.931*). A significant and negative correlation of calcium carbonate was observed with available nitrogen (r = -0.871*) and phosphorous (r = -0.906). The organic carbon content shows significant and positive correlation with available nitrogen (r = 0.936*), phosphorous (r = 0.986*), respectively. [ABSTRACT FROM AUTHOR] |
