Well diffused land-use systems with annual food and/or fibre
crops are described. Dynamic simulation of biophysical production potential,
water-limited production potential and fertilizer (input) requirements for
target production on the basis of commonly available data on land (i.e. soil
and weather), crops(s) and management/technology. General model and
derived version for systems with saline water and/or soils.
