The adoption of voluntary nutrients reduction technologies issignificantly explained by the variables on farm slope, farmers’ age,farmers’ attitude to subsidies, farm size and farmers’ awareness ofthe existence of the constructed wetland funds. Despite the farmsize variable being highly significant in explaining the model, theother economic factors included in the model are insignificant. Inthe perception model, all the physical factors are significant exceptfor the distance variable. None of the personal and attitude vari-ables are found to be significant in determining perceptions ofwater quality, while economic and institutional factors produceone significant variable each. Overall, the significant variables inthe perception model include soil types, farm slope, full-time farmtype and farmers’ subjective reception of information on good eco-logical status. All the significant variables in both models displaythe hypothesized direction in their relationship with the dependentvariables. Surprisingly, the predicted adoption variable which wasexpected to significantly influence farmers’ perception on waterquality is insignificant in perception model. The results of the esti-mation coefficients and marginal effects of the significant variablesare presented in Tables 6 and 7. Reporting the marginal effects isnecessary so as to show the direction of change for all levels of Yigiven a change in the Xi’s. Both the coefficients and marginal effectsare used in the discussion of the results although the marginaleffects are given more emphasis.
