| الوصف: | An assessment of soil fertility of Northern Light Soil area of FCV tobacco was carried out to study the status of soil macro and micronutrients. Soils of the study area are mostly moderately acidic in nature with low organic carbon and available nitrogen with a mean value of 0.29 % & 110 kg ha-1, respectively. Available phosphorus was high (88% samples) with a mean value of 92.6 kg ha-1. While the average available potassium content was 297 kg ha-1 with 48 % samples in medium class. Among available micronutrients, the available zinc content in 73 % of samples was very low – low (0.0 to 0.6 ppm). Whereas the availability of copper in 25 % samples was very low to low as per the fertility class (0.0 - 0.30 ppm). Available iron (18.8 -35.03 ppm) and manganese (17.03-21.5 ppm) contents were high in the region. Nutrient index of available nitrogen was 1.00 (Low) while, NI was 2.83 (High) & 2.36 (Medium) for available phosphorus and available potassium, respectively. |
