“…This increase in DM production is likely to occur through a reduction in N loss resulting from the application of the nitrification inhibitor (Di & Cameron 2002, 2005. Unknown, however, is why it appears less effective in some NI regions, specifically the Waikato, but at the same time is very effective in other NI regions such as Taranaki.…”

“…Published research in 2002 first showed its potential effectiveness in Canterbury to reduce nitrate leaching and nitrous oxide emissions within urine patches (Di & Cameron 2002, 2005. It was also noted that in reducing losses of urine-N to both processes, there is an increased potential for the retained N to increase dry matter (DM) production and reduce N fertiliser application, thereby increasing farming efficiency and productivity.…”

The use of nitrification inhibitors has become increasingly common on dairy farms in NZ since 2004, ostensibly to reduce nitrogen (N) loss from nitrate leaching and nitrous oxide emissions. A potential benefit of this reduction in N loss, however, is an increase in dry matter (DM) production. Pasture response data were collated from a national series of farm trials conducted in 132 paddocks on 37 farms in the North Island (NI) and South Island (SI) of New Zealand where paddocks were randomly split into two halves with one half treated with the nitrification inhibitor eco-n TM . Measurements conforming to a strict protocol were made using pasture plate meters. There was a highly significant overall DM response to inhibitor use of 19% across all trials (14% NI, 21% SI) although full-year responses were more variable between NI regions (4Á27%) than SI regions (12Á31%). Generally, DM responses were greater than those demonstrated by previous small-scale experimental trials and this may indicate the influence of a farmÁsystem effect. Several reasons are speculated for this effect but further research is required to identify the factors involved.

“…There are some temporary technological fixes, such as the application of dicyandiamide to inhibit nitrification of animal urine (Di & Cameron 2005). Some improvements can be achieved by movement back to former mixed systems (Bechmann & Stalnacke 2005;Bengtsson et al 2005;Boody et al 2005;Pimental et al 2005).…”

Agriculture disrupts all freshwater systems hugely from their pristine states. The former reductionist concept of pollution was of examining individual effects of particular substances on individual taxa or sub-communities in freshwater systems, an essentially ecotoxicological concept. It is now less useful than a more holistic approach that treats the impacts on the system as a whole and includes physical impacts such as drainage and physical modification of river channels and modification of the catchment as well as nutrient, particulate and biocide pollution. The European Water Framework Directive implicitly recognizes this in requiring restoration of water bodies to 'good ecological quality', which is defined as only slightly different from pristine state. The implications for the management of agriculture are far more profound than is currently widely realized.

“…Marandu, it was observed that N-sources do not change the performance of dry matter; however, urea with urease inhibitor and polymer-coated urea improved NUE [22]. Urea mechanical incorporation or rain after N-fertilizer application can decrease the amount of NH 3 -N losses, due to higher speed of urea incorporated in soil [11].…”

“…Even with high response to N-fertilizer rate by tropical forage, resulting in increasing crude protein (CP), and other bromatological features [10], the risk of higher downward residual NO 3 -N movement in soil and high concentration of NO 3 -N in biomass due to N-fertilizer above plant requirement must be considered to avoid environment contamination and animal health problems [11,12].…”

There is a concern about the growing population and limitation in natural resources which are taking the population to direct its agricultural systems into a more productive and efficient activity, looking to avoid a negative impact on the surrounding environment. The industry energy expended to produce nitrogen (N)-fertilizer is considered an indirect consumption of energy in agriculture, which is higher with an increasing forage yield. Nitrogen is the key nutrient associated with high-yielding production in forage grass and grain crops. The aim of this chapter is to introduce the best management practices (BMPs) for N-fertilizer application in forage grasses to improve N-use efficiency, since the most economical way to feed livestock is forage plants where its potential biomass production is not well explored. The BMPs basically follow three management practices: (1) soil nutrient availability and forage requirement, (2) fertilizer application, and (3) decrease in nutrient losses from soil. In order to take a decision on applying N-fertilizer to accomplish forage grasses production with social, economic, and environmental benefits, the N-fertilizer use in forage grasses is going to follow the "Right rate, Right source, Right place, and Right time (4R) nutrient stewardship." The application of the 4R's nutrients stewardship is directly associated with economic, social, and environmental impact. The capacity of the 4R's implementation worldwide turns into a best guide to improve the striving of better N-use efficiency in forage grass. The 4R's are interrelated; thus, the recommendation of N-fertilizer rates cannot be prescribed without the combination of the 4R's where a whole system to be followed should be considered to decide about N-fertilizer in pasture. Consequently, any decision in one of the 4R's is going to affect the expected N-fertilizer results and dry matter production.
