Abstract

Soil information is a critical element in any agricultural venture. It often provides the missing link between assumptions and actuality in agricultural and non agricultural land use. A field study was carried out to assess the effects of poor application of soil information and the present level of soil information and utilization among small scale horticultural crop farmers in Ibadan, Oyo state. Six candidate citrus trees each were selected from two citrus orchards planted on suitable and marginally suitable soils based on available soil survey information which was monitored over two seasons, while structured questionnaires were administered to get empirical data on land use by the farmers. There was over 35% yield difference and this was significantly different (P <0.05) with loss of some trees after 15 years of establishment of the orchard on marginally suitable soils. Mean yield per tree was 50.43kg and 30.12kg for suitable and marginally suitable plots respectively. None of the respondents sought professional advice on land use or have knowledge of previous land use type while the farms were not surveyed before use. 56.27% of the farmers do not carry out soil test while less than 10% of the farmers apply fertilizers suggesting nutrient mining with an average land use period of 14years. The findings of this work show that soil information is not adequately utilized among horticultural crop farmers in Oyo state. Therefore, there is need to enlighten farmers on the need for accurate soil information and application for enhanced horticultural crop production.
