Modeling of soil nitrogen content under conditions of diverse agricultural crops
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2018, Vol 63, Issue 2
Abstract
The paper presents a mathematical model of nitrogen migration in soil. Nitrogen changes were modeled over a period of 21 months, taking into account the change of the cultivated plants, nitrogen uptake by plants during their growth and depending on soil moisture, fertilization and changing weather conditions. The equation of the mathematical model was solved by the finite difference method. The obtained results were verified with the soil laboratory data. The quantitative compatibility was obtained in the case of the upper layer of soil profile (0-30 cm) and qualitative - for the deeper layer (30-60 cm). The mathematical model allows taking into account many different impacts on the content of Nmin. in the soil. It can be a helpful tool in forecasting its changes and determining the time and level of fertilization. This is of particular importance when the weather conditions undergo radical, long-term changes.
