Popis: | This paper investigated whether the Teakplantation established a year agoby Lagos State Government Ministry of Agric and Co-operative at Abia-Badagrymeet the soil and environmental requirement as obtainable in countries where Teakgrows naturally. Also the study will also establish whether the establishment ofTeak tree has changed the soil properties. Sampling design for this study wasbased on, the need to spread sample sites objectively over the study area. Theentire plantation is 2.5ha and five soil samples were collected from the plantationusing soil auger. From each of thefive (5) holes dug, soil samples were randomlycollected from two sampling depths 0 - 15 em and 15-30cm, respectively. Soilsamples were air-dried, sieved, 'and analyzed in the laboratory using standardtechniques. The result of the soil analysis show that PH, EC, TOM, TOC, TN, Av.K,Av.P and Bulk Density ranges between,5.36-5.86,38.00-156.00,1.06-2.41,0.86-1.92,0.01-0.03,0.03-0.03,0.02-0.02 and 1.31-1.36 respectively. Among theexamined variables,Ec has the highest mean (61.00) followed by pH (5.72) whileTN/Av.P remained the least value (0.02). Also, EC recorded the highest StandardDeviation (46.73).this was followed by TOM (0.52) while Av.K/Av. Based on theempirical data and the analysis carried out on the Teak plantation and the sitecharacteristics tofind out the suitability or otherwise of the site for maximum Teakyield in the country, it was found that the site characteristics, especially, soilproperties are similar to those'of places where Teak grows naturally. Therefore itis recommended to Lagos State Ministry of Agric and Cooperative to increase theplantation size. |
