At present, the increasing demands for farming in the direction of sustainability. These include strengthening the positive and eliminating the negative environmental impacts such as erosion, unwanted contamination of agricultural land etc.
For this purpose it was designed and approved by the Technology Agency CR project "Model FARMA 5 - Guidance optimization system for simulating the optimal behavior of agricultural enterprises in relation to the sustainability of agriculture and agricultural technologies in an environmentally friendly, with links to geographic information system".
The advisory system FARMA 5 consists of the following components: a mathematical model FARMA 5 for spatial optimization of production structures on the basis of soil blocks, created in the GAMS; model ERO 1 for the erosion hazard based on GIS based on classification BPEJ; models EMI 1, IMI 1, DEP 1 to determine the impacts of atmospheric nitrogen deposition to agricultural land through the balance of NPK.
The mathematical optimization model FARMA 5 calculates the optimal production structure of the company matching given inputs based on the variant task optimization, and economic optimization (maximization of profit enterprise, regardless of environmental constraints), one ecological optimization (maximization of company profits while taking into account the erosion hazard established model ERO 1), environmental optimization 2 (maximizing company profits while taking into account the balance of N in relation to the results of models EMI 1, IMI 1, DEP 1) and 3 environmental optimization (maximization of company profits with different combinations of organic optimization 1 and 2). The use of advisory system FARMA 5 is assumed as at the corporate level and decision-makers at the Ministry of Agriculture to simulate the impacts of future agricultural policy options.
