Modeling A Fertilisant Dynamic Transformation In ‘soil-plant’ System
Authors : Aouachria Z. .
Abstract
The application of fertilizers is one of the conditions for obtaining the resistant cultures. Effectiveness of contribution fertilizers such as phosphorus, the nitrogen, etc…depends on many factors to knowing: properties of the soil, the request of the plants out of fertilizers (phosphorescence for example) and also on the form and the application method of fertilizers. Several results show that rational of organic and inorganic manure applications not only increase the production but also can support a stable level of the production. The mathematical model of the transformation of fertilizer in the system ‘soil plant’ is presented in this work. We showed that there is a stable mode for the system ‘soil plants’. The strategy of the fertilizer application, permitted to provide this regime, has been determinate.
