Nitrogen (N) fertilization decisively influences the yield of arable crops as well as increases
N surplus, thereby leading to N losses to the environment. The study aimed to estimate the …

Agronomic research on crop response to nitrogen fertilizer suggests that a plateau function
may be appropriate, but the plateau varies across fields and years. Available models that …

This study presents a dynamic regional sector model for Finnish agriculture (DREMFIA) to
be used in evaluating the effects of different agricultural policies on production and …

Abstract Accession to the European Union caused a drop of nearly 60 per cent from 1994 to
1995 in prices of wheat, barley and oats in Finland. The economic use of fertilizer therefore …

Estimation of nitrogen response functions has a long history and yet there is still
considerable uncertainty about how much nitrogen to apply to agricultural crops. Nitrogen …

A method of estimating a linear response stochastic plateau function is developed and used
to determine optimal levels of nitrogen fertilization for wheat. Under the stochastic plateau …
