      abstract = {von Liebigs law of the minimum is frequently proposed as a  model of crop production which captures agronomic reality  better than substitutional production functions. Whilst  many studies of the law of the minimum and optimal  fertilizer carryover
have been undertaken separately, the  law of the minimum for optimal fertilizer carryover
has it  would appear until now not been analysed, because of the  non-differentiable
nature of the agricultural producers  objective function. In this paper I develop an
optimal  control model of fertilizer carryover subject to the law of  the minimum using
the differential inclusion approach to  optimal control.},
