“…This is supported by the present results, showing that N surplus significantly (P < 0.001) increased with increasing animal density and milk yield per cropped farm area (Table 4). In the Netherlands, for example, milk output per cropped farm area may be 10000-12000 kg ha -1 on typical dairy operations, resulting in at least 200 kg ha -1 N surplus even though special measures to improve whole-farm nutrient utilization are adopted (Van Keulen et al 2000). When extrapolating the present data to Vol.…”

“…Van Bruchem et al 1999, Van Keulen et al 2000, Oenema et al 2003 and the United States (e.g. Van Horn et al 1996, Spears et al 2003a demonstrate that a systematic analysis of whole-farm balances of nutrients (WFB; the difference between nutrient flows into and out of a dairy farm) as a first step is essential in improving the efficiency of nutrient use in milk production.…”

“…Increasing amount of data is available from elsewhere in Europe (e.g. Van Keulen et al 2000, Swensson 2003) and the United States (Spears et al 2003a, b). The number of dairy farms in Finland is decreasing with simultaneous increase in production intensity, whether expressed as milk yield per cow, farm or land area.…”

“…It is generally accepted that whole-farm nutrient balances are satisfactory descriptors of potential nutrient load from milk production to the environment (Van Keulen et al 2000, Schröder et al 2003. In addition, the uncertainties for WFB are obviously less than for soil and soil system nutrient balances (Oenema et al 2003).…”

The calculation of whole-farm nutrient balance is an effective and simple method for estimating the potential nutrient loading from dairy farming into the environment. In Finland, however, the published results based on larger number of farms are still lacking. In this study whole-farm nitrogen (N) and phosphorus (P) balances on Finnish dairy farms were studied based on short-cut data for the year 2002. The survey was targeted to 1260 dairy farms, located all over Finland. Of the 386 replies received, 319 were used for subsequent statistical analyses. The association between selected farm variables and nutrient balance was studied using regression analysis and a sensitivity coefficient was calculated for each regression slope. The average (± standard deviation) whole-farm nutrient balance for N and P was 109 (±41.3) and 12 (±7.2) kg ha -1 , respectively. The most responsive factors affecting the nutrient balances were total nutrient and fertilizer import per ha, followed by animal density, milk export per ha and concentrate import per ha. The results suggested that nutrient surpluses could be controlled more easily in combined crop and milk than in specialised milk production. It is concluded that nutrient surplus on Finnish dairy farms is markedly lower than that on areas with intensive production in central European countries. However, when nutrient balances were extrapolated to comparable production intensity as in central Europe, the level of the surpluses was equal.

“…Some research focuses on improvement of animal production systems [17,36,37,38,39,40] and crop production systems [41]. Other research is devoted to the role of animals in global food production [42,43] and global food production in the next decades [44,45,46].…”

Nitrogen Efficiency in Agriculture in Europe and India

Nitrogen balance sheets are useful tools for studying the quantitative aspects of nutrients. Nitrogen balance sheets have been prepared for the animal production system, crop production system, and for the agricultural sector as a whole for all 15 member states of the European Union (EU15) and for the Indian subcontinent. The EU15 and India were chosen for this study on nitrogen efficiency using balance sheets because they each occupy roughly 300 million ha of land and use about 65 kg nitrogen fertiliser per hectare of agricultural land. Balance sheets were constructed for three systems: animal production, crop production, and the agricultural sector as a whole. In addition to detailed descriptions of the nitrogen balance sheets, brief recommendations for reducing nitrogen surpluses are also given. Surprisingly, the balance sheets for crop production and the agricultural sector as a whole showed a surplus of about 60 kg of nitrogen per hectare of agricultural land.
