Description
To maintain a good productivity in the soil-plant-animal system it is necessary to achieve an equilibrium between input and output of nutrients and energy. Models and simulation software have been proposed for this purpose. For dairy farms, models have been utilised to show the behaviour of different aspects, such as: feed utilisation, energy flow, digestibility values and daily weight gains (Freer et al., 1970; Assis & France, 1983, Bruce et al., 1984). However, there are few models showing the interaction between soil-plant- animal components of these systems. The objective of the present study was to validate the software "Recycling of Nutrients" proposed by Ortiz (2000) for dairy farms of western Cuba.
