Abstract
results establishing a positive relationship between agricultural product demands and equilibrium soil quality are reestablished in a spatial setting where farmers utilise soils of different intial quality.The same positive equilibrium relationship emerage as optimal with a single reproducible fertility factor when soil fertility investmant costs are convex in the level of fertilizer application regardless of whether farmer spending is budget-constrained.Introducing non-reproducible intrinsic fertility leads to differential optimal fertiliser applications but the positive relation between soil quality and product price (or demand) remains.
