Abstract

Background: Natural levels of soil nutrients are spatio-temporally variable and insufficient for agricultural purposes. Artificial fertilisers are applied to achieve higher crop growth rates and yield. Mitscherlich’s equation and Boule’s fertilizer units are described and illustrated in relation to crop yield then applied to estimate the nitrogen (N)-pool fraction in the soil that contributes to a component of greenhouse gas (GHG) emissions, specifically the nitrous oxide (N2O) flux.
Methods: Mitscherlich (1909) proposed a diminishing returns model to extract information about soil N status for production responses. Mitscherlich’s equation was generalised by Baule (1918) and modified by Bray (1945) to account for soil nutrient contributions for multiple fertilisers. These models are examined in this study.
Results: Their application results in the extraction of further information on soil nutrient variability and N2O emission across spatial locations.
Conclusions: Mitscherlich’s equation and Boule’s fertilizer units are useful tools to study soil-fertiliser interaction and compare soil fertility and GHG emission.
