This research studies the rationale and conceptual framework underlying the hedonic approach that can decompose farmland values into its hedonic and location characteristics. The study will examine determinants of farmland prices, including a myriad of agricultural factors (such as soil productivity, acres in sales, improvement structure, slope aspect, and climate) and non-agricultural factors (such as distance to urbanized areas, distance to major roads, distance to freshwater wetlands, social demographic and economic characteristics, and regional influence). Understanding the roots of farmland price volatility is a concern to agricultural producers, government officials, developers, and investors. These interest groups commonly participate in conflicts surrounding agricultural restructuring, land use planning, property taxes, economic development, and farmland conservation. Insight into how agricultural and other factors influence farmland prices would benefit all concerned as communities wrestle with plans to promote growth in the non-agricultural sector that maintain and sustain opportunities for agriculture.A high-quality transactions-based data set will be used to estimate hedonic price models of individual farmland parcels. The hedonic results focus on how using spatial data and Geographical Information Systems (GIS) can improve the accuracy of farmland valuation models. However, research using actual farmland sales data presents analytical challenges, because each farm parcel is unique, possessing its own set of spatial and morphological features. The issues of spatial dependence and spatial heterogeneity will be further investigated and alternative model specifications need to be tested for improving hedonic models that reflect the actual farmland market value.
