The quest for balance in crop modeling
WebbThe use of nutrient balance analysis in establishing fertilizer recommendations is based on the principle of replacement: the nutrients added in fertilizers should replace the … WebbThe concept of crop modeling dates back to the 1960s when researchers modeled agricultural systems by combining both physical and biological principles. Crop models rely on measurable inputs (by sensors, machines, or hand measurement) to determine whatever output is of interest (plant growth, crop yield, soil nitrogen, crop staging, etc.).
