| Popis: | A study was conducted to assess the status of available zinc in soil of Teaching and Research Farm, Modibbo Adama University, Yola North East, Nigeria. Ten soil samples were collected from 0 – 20 and 20 – 50 cm depths to reflect the soil of the study area. The soils were analysed following standard laboratory procedures. Result obtained showed that the soils were sandy loam to sandy clay loam, slightly acidic (mean = 6.4 – surface; 6.5 – subsurface soils), very low OC content (mean = 0.35 % – surface; 0.27 % – subsurface soils), low to medium Total N and exchangeable bases. Zinc was generally low to medium (range = 0.18 – 1.71; mean = 1.12 % in surface soils, and range = 0.32 – 2.71; mean = 1.35 % in subsurface soils). Zinc is not correlated with most of the soil properties in both soil depths. In surface soil, a positively correlation with potassium (r = 0.702*) was observed and negative correlation with Total N (r = -0.634*) in subsurface soils. It is recommended that for successful and profitable crop production, application of inorganic fertilizers plus zinc and organic material should be encouraged. |
