This paper uses multiple regression analysis to examine the effects of energy resource development on sale prices of agricultural land in western North Dakota. The findings suggest that energy resources development has exerted only modest upward pressure on agricultural land values in the northern Great Plains. The land market in this region remains dominated by active farmers who are purchasing farmland as a long-term investment, and energy development has not had a major impact on the structure of that market.

This study develops a dynamic multi-output model of farmers’ crop allocation decisions that allows estimation of both short-run and long-run adjustments to a wide array of economic incentives. The method can be used to inform decision makers on a number of issues including agricultural policy reform and environmental regulation. The model allows estimation of dynamic effects relating to price expectations adjustment, investment lags, and crop rotation constraints.

Great share of rented land in total utilised area as well as a significant variability of land rent and market prices of land causes a need of research that would assess which factors influence the land rent as well as the price of land and how significant such factor are in each state. The average land rent is significantly lower in new EU member states than in the EU 15 members. There is a strong dependence of land rent on the intensity of production. Subsidies have moderate to medium influence.

This paper evaluates how much longer setback lengths associated with surface application must be to encourage soil injection of swine manure in Kentucky. Results indicate that proposed setback lengths do not encourage odor control via injection; the setback length associated with surface application must be substantially longer than that associated with injection.

In course of the research there was resulted the developed model of optimization of the sizes of land tenure of the agricultural enterprises. The research was realized in the conditions of the Republic of Belarus. As a result of realized research the optimum sizes of land tenure of the agricultural organizations with combinational organizational-industrial structure for average conditions of republic were established.
