Modeling Cumulative Effects of Nutrient Surpluses in Agriculture: A Dynamic Approach to Material Balance Accounting

Eco-efficiency Assessment in Agriculture: A Literature Review Focused on Methods and Indicators

“…Pollution control was also found as an outstanding research purpose (Kuosmanen & Kuosmanen, 2013;Kuo et al, 2014;He, Wan et al, 2016;Reboledo-Leiva et al, 2017). Also related to greenhouse gas emission and climate change, some articles aimed at building scenarios under a future climate (Niero et al, 2015;Vlontzos & Pardalos, 2017).…”

Phosphorus resources, their depletion and conservation, a review

“…In these areas P additions well beyond crop requirements have been noted, with major regional differences in the degree to which crop requirements are exceeded (e.g. Günther, 1997;Lansing et al, 2001;Linderholm et al, 2012a;Kuosmanen and Kuosmanen, 2013). Accumulated P stocks in agricultural soils may become very high.…”

“…In improving P resource conservation, current side-effects of P use such as ecosystem deterioration due to eutrophication and human intakes of P which are too high may be reduced, if compared with 'business as usual' (Smith et al, 1999;Smil, 2000;Kumar et al, 2010;Ellam and Chico, 2012;Kuosmanen and Kuosmanen, 2013;Brinch-Pedersen et al, 2014).…”

Estimating stocks and flows of nitrogen: Application of dynamic nutrient balance to European agriculture

“…However, if one is interested in analyzing the development of nutrient accumulation in a country or a region, or assesses nutrient accumulation in cross-country comparisons over time, it is important to consider the dynamic nature of the nutrient cycle. To calculate the stock of nutrient z in country i, we apply the model of DNB developed in Kuosmanen and Kuosmanen (2013). Following their reasoning, the quantity of nutrient stock Z in year t can be estimated by an accumulation of past nutrient net inflows h it depreciated over time as:…”

“…The recent study by Kuosmanen and Kuosmanen (2013) critically examined the conventional approach to material balance accounting as applied to nutrients in agriculture arguing that the NB approach ignores the accumulation of nutrients to the environment and importantly, overlooks the dynamic nature of the nutrient cycles. By applying the standard model of capital accumulation in production economics, Kuosmanen and Kuosmanen propose a dynamic model of nutrient balance (henceforth DNB).…”
