Phytomass Growth Model (PHYGROW ) - A Grazing and Range Land Assessment ModelEntry ID: TAMU_PHYGROW
Abstract: Phygrow is a daily time step computation engine that models above ground herb and shrub growth, forage consumption, and hydrologic processes. It is capable of modeling growth dynamics of many plant species competing for limited resources while modeling grazing by herbivores in competition for forage resources.
PHYGROW is a point-based, daily time step, algorithmic or computation engine that ... models above ground plant growth, forage consumption and hydrological processes. The model was first coded in 1990 and has undergone many enhancements since that time. The model's original computation algorithms are a mixture of formulas adapted from other plant growth models (CREAMS, GLEAMS, EPIC, WEPP, SPUR, CENTURY, ERHYM-II). as well as biological relationship from grass tiller level research and dietary selection conducted at Texas A&M University.
The model is capable of simulating growth of multiple species of plants subject to selective grazing by multiple animals on a soil with multiple layers for indefinite periods of time. The model is designed to be integrated with a wide variety of weather databases, vegetation databases, and stocking rule databases and provide output for a wide variety of data sources and formats including all relational databases, netcdf file formats, .commas separated and tab-delimited file formats, and linkages to other models and the internet using Python, Perl, and Java web applications.
