概要	Tillage Erosion Model is a physical transport and modeling pipeline for predicting soil movement and redistribution caused by tillage operations on sloping land. Developed by soil scientists (Lindstrom, Nelson, Lobb) in the 1990s–2000s, this method quantifies how plowing, disking, and other soil-disturbing implements physically move soil downslope, leading to long-term productivity loss on upper slopes and soil accumulation in valleys.	Nitrogen Use Efficiency (NUE) assessment and optimization is an analytical pipeline for evaluating how effectively crops convert applied nitrogen fertilizer into grain, biomass, or economic output. Developed by agronomic researchers (Dobermann, Raun) in the 2000s, this method quantifies nitrogen losses and identifies management practices to improve both crop productivity and environmental sustainability.
