Abstract:

ALMANAC (Agricultural Land Management Alternative with Numerical Assessment Criteria) is a predictive and process oriented model which simulates the hydrology and erosion as in the EPIC model, but it is also able to simulate competition between 2-10 plant species. It includes detailed functions for water balance, nutrient cycling, plant growth, light competition, population density effects, and vapor pressure deficit effects. ALMANAC is a useful tool for simulation management strategies related to weed control (Kinery, J.R. et al., 1992).

The model requires readily available weather and soil inputs and parameters specific to plant species which can be derived from the literature. The model simulates daily time steps on the field level which can be aggregated to annual and multi-year runs.
