 Marx aims to show that capitalism turns agriculture into a business like any other, operated for purely commercial motives; and that the ground rents appropriated by landowners are a burden for the industrial bourgeoisie both because they imply an additional production-cost and because they raise the prices of agricultural output.More specifically, Marx intended to show how the law of value governed capitalist farming, just like it governed capitalist industry.The peculiarity of capitalism in agriculture is that commerce has to adapt to physical factors such as climate, altitude and soil quality, the relative inelasticity of agricultural supply, and the impact of bad harvests on international prices for farm products.
