The Influence of Technological Progress on the Long Run Farm Level Economics of Soil Conservation

摘要: The complementary interaction between topsoil depth and technical progress for winter wheat in the Palouse region was found to strengthen long run payoff conservation tillage. Nonetheless, tillage be competitive with conventional only if its current yield disadvantages were eliminated. Conservation relatively more on shallower topsoils longer planning horizons. Short-term subsidies coupled research directed towards reducing cost of advocated maintain long-term soil productivity. A dynamic perspective is crucial a comprehensive evaluation private benefits conservation. An analysis through time facilitates an examination depressing effects erosion increasing improvements agricultural technology. approach also makes it possible examine influence different discount rates lengths horizons economic attractiveness various control practices. This important from policy standpoint because potential differences individual farmers society as whole respect appropriate could lead substantial
