Abstract Grassland renovation is a relatively expensive activity. However, a cost/benefit analysis is hard to make, since financial benefits are difficult to determine. The benefits involve mainly the temporary increase of net grass production. The focus of this paper is on a model simulating the grass production over time. It assumes that the gross grass production, the nutritive value and the intake of grass by cattle decline over time due to an increasing content of undesirable grass species, like Poa trivialis and Elymus repens. This model approach is the basis for the 'Grassland Renovation Guide', a computer program which runs on the Internet site of our institute (www.asg.wur.nl). Farmers can use this program for a cost/benefit analysis, depending on factors such as actual costs, present content of desirable grasses and clover, soil type, groundwater level, irrigation and N fertilisation level. The tool provides a cost benefit analysis and a nitrogen balance. For the given situation, it states whether grassland renovation is profitable under a wide range of circumstances.
