摘要:
On the basis of what is known from the literature an attempt has been made to estimate the yields in an agricultural system that is supplied with nitrogen from natural sources. For this purpose a model of Dutch agriculture is developed in which only nitrogen is considered as a variable and all other production factors (like phosphate, potassium, water, plant variety, and the skills of the farmer) are considered to contribute to productivity in their usual manner.
