The objective in this study was to explore factors that shape how residents manage their home landscapes, and we applied Rogers' (2003) Diffusion of Innovations to understand fertilizer practices and implications for Extension programming to address non-point source pollution. Data were drawn from a statewide survey of 1,197 Floridians. We identified the extent to which Floridians were using 10 residential fertilizer best practices, how Floridians' perceived characteristics of fertilizer innovations related to adoption, and evaluated how the educational needs pertaining to fertilizer use differed among non-innovative and innovative individuals. Respondents were most engaged in practices such as reading fertilizer packages and labels to apply the correct amount and least engaged in soil testing to inform fertilizer applications as well as asking their landscape professional about training. Floridians perceived the five characteristics of fertilizer best practices at a moderate level overall, and of these, characteristics, compatibility, trialability, and relative advantage predicted adoption. Innovative individuals were more interested in learning from colleagues, neighbors, and public organizations such as Cooperative Extension and government organizations. They were also more interested in learning by visiting an Extension office or through social media than those who were non-innovative. This study may inform policymaking such as local landscape ordinances and planning of Extension behavior change programs. [ABSTRACT FROM AUTHOR]

Water quality is a complex issue and residential fertilizer can be one of the many contributors to poor water quality. Working with residential audiences to help them understand and reduce their impacts on water quality is an important task among many agricultural education and Extension professionals. In order to effectively work with residential audiences, we must first understand what influences their intent to engage in fertilizer best management practices. In this research, we paired the Diffusion of Innovations and Elaboration Likelihood Model to examine the influence of perceptions of an innovation's characteristics, personal involvement with water, and communication on intent to engage in fertilizer best management practices. The communication was presented to experimental groups as a 35-second video about fertilizer best management practices. Data were collected via a survey instrument and were analyzed using inferential procedures. Four of the five characteristics of innovations significantly influenced intent to engage in fertilizer best management practices among the control group. However, all five characteristics were significant among the entire sample but the influence was less compared to the control group. Involvement increased intent while the video treatments had little effect. The results of the research support existing findings, but also offer areas of new discovery as well as insights for practice and additional study. Future research should examine the repetition of communication as well as different dimensions of involvement. [ABSTRACT FROM AUTHOR]

Water quality and availability are critical issues currently addressed by agricultural education professionals. Extension professionals need to employ innovative approaches to help residents adopt practices and technologies to reduce the impact of urban landscapes on water resources. This study explored how individuals' dissatisfaction relative to their perceived importance of either clean water for large and local water bodies or plentiful water for local water bodies related to their intent to engage in landscape best management practices following a tailored message. Individuals were randomly assigned to receive a message appealing to improving water quality through good fertilization practices or a message appealing to improving water availability through good irrigation practices. Those who assigned higher importance but perceived lower satisfaction with clean water had greater likelihood of engaging in most fertilizer best practices after receiving a tailored message compared to those who assigned lower importance and perceived higher satisfaction with clean water. Those who assigned higher importance but perceived lower satisfaction with plentiful water were more likely to engage in one of the five irrigation best practices compared to those who assigned lower importance and perceived higher satisfaction with plentiful water after receiving the message. Agricultural education programs should tailor messages to dimensions clientele perceive as important but with which they are unsatisfied, especially when intent is lower. [ABSTRACT FROM AUTHOR]
