Paragraph4: As the demand for agricultural produce from both consumers and industry increased, agricultural land became more valuable and people tried to work the available land moreintensively and to reclaim more land from wetlands and lakes. In order to increase productionon existing land, the peasants made more use of crop rotation and, in particular, began toapply animal waste to the soil regularly, rather than leaving the fertilization process up to thegrazing livestock. For the first time industrial waste, such as ash from the soap-boilers, wascollected in the cities and sold in the country as artificial fertilizer. The increased yield andprice of land justified reclaiming and draining even more land.
