Summary
Smaling and Fresco (1993) developed NUTMON, a decision-support tool for monitoring nutrient balances under different agricultural land uses. The model appears designed to integrate nutrient flow data and provide farmers and land managers with quantitative information on nutrient cycling and depletion risk. As a methodological contribution from the early 1990s, this work represents an early systematic approach to spatially explicit nutrient balance assessment in farming systems.
Regional applicability
The paper presents a generic methodological framework rather than site-specific findings. The NUTMON model's applicability to United Kingdom agriculture would depend on data availability and adaptation to UK soil and climate conditions, though the underlying nutrient accounting principles are universal.
Key measures
Nutrient balance components; soil nutrient status; agricultural land use classification
Outcomes reported
The study presents a decision-support model (NUTMON) designed to monitor and assess nutrient balances across agricultural land uses. The model aims to track nutrient flows and identify imbalances that may affect soil fertility and sustainability.
