title: [The application of a dynamic feedback control model to the estimation of the expenditure-dependent growth plateauing in forest stands].
abstract: In addition to the time-dependent description of growth an expenditure-dependent parameter is necessary, with the help of which it is possible to interpret quantitatively the expenditure of economically motivated silvicultural measures in forest stands. The solution of a differential equation contains the desired expenditure parameter, the time-dependent and site-index-dependent courses of pine stands are discussed in this paper as normal and additional expenditure for obtaining an additional increment by fertilisation.
