“…Despite this, information on the comparative effects of different manure application methods in Canada is scarce and, to date, limited to tame pastures (e.g., Bittman et al 1999;Olson and Papworth 1999). The benefits of alternative manure application methods to splash-plate application have included a greater capture of nutrients, particularly N (DeKlein et al 1996;Sanderson and Jones 1997;Bittman et al 1999).…”

Blonski, L. J., Bork, E. W. and Blenis, P. V. 2004. Herbage yield and crude protein concentration of rangeland and pasture following hog manure application in southeastern Alberta. Can. J. Plant Sci. 84: [773][774][775][776][777][778][779][780][781][782][783]. Intensive hog production is expanding into semi-arid regions of Alberta, where perennial forage lands are increasingly targeted for manure application despite limited guidelines for its efficient use. Herbage yield and crude protein were assessed over two consecutive years within two native rangelands and two tame pastures, following different rates (10, 20, 40, 80 and 160 kg ha -1 NH 4 -N), methods (surface banding vs. subsurface injection) and seasons (fall vs. spring) of one-time liquid hog manure (LHM) application. Increasing manure rates improved grass yield across all sites the first growing season after treatment, from 1626 to 3576 kg ha -1 . Although absolute increases in production were greatest on tame pasture, relative yield increases were similar among sites. Average crude protein (CP) concentration also increased from 69 to 91 g kg -1 in the first year. Despite low rainfall and the absence of a yield response in the second year, grass CP and crude protein yield (CPY) were maximized with increased manure application, highlighting the positive effects of manure on forage production, even with drought. Forb yields demonstrated variable effects among sites, with increasing manure decreasing alfalfa and increasing native forbs. Overall, both semi-arid tame pastures and native rangelands responded positively to LHM application, highlighting the complementary nature of hog and forage production under these conditions. Le rendement fourrager augmente avec le taux d'application à tous les endroits la saison végétative suivant le traitement pour passer de 1 626 à 3 576 kg par hectare. Bien que la production augmente davantage dans les prairies artificielles en termes absolus, le rendement relatif demeure le même aux différents endroits. La quantité moyenne de protéines brutes s'accroît elle aussi la première année, soit de 69 à 91 g kg -1 . Malgré la pluie et l'absence de réaction du rendement la deuxième année, la concentration de protéines brutes des herbages et le rendement en protéines brutes atteignent leur maximum avec l'augmentation du taux d'application, ce qui souligne les effets positifs du fumier pour la production fourragère, même quand il y a sécheresse. Le rendement en herbacées dicotylédones révèle que la réaction varie d'un site à l'autre, la production de luzerne diminuant et celle d'herbacées dicotylédones indigènes augmentant avec l'application de fumier. Dans l'ensemble, les prairies artificielles et les grands parcours naturels des régions semi-arides réagissent bien à l'application de lisier, signe que l'élevage de porc et la culture fourragère sont complémentaires dans de telles conditions.

“…The ability of organic fertilizers to provide N is, however, not just reduced by this untimely mineralization. The inherent composition of organic N fertilizers can also stimulate other loss processes such as denitrification [22] [23] and volatilization of ammonia [24]. This limited availability of N from organic fertilizers can be expressed in so-called N fertilizer replacement values (NFRVs).…”

The Position of Mineral Nitrogen Fertilizer in Efficient Use of Nitrogen and Land: A Review

Our attitude towards mineral nitrogen (N) fertilizers is ambivalent. N fertilizers have on one hand increased our supply of food, feed and other bio-based raw materials tremendously and also improved the use efficiency of land and labor, but have on the other hand a negative impact on the quality of the environment and contributed to the depletion of fossil fuel reserves. This awareness has resulted in strong pleas to spend much more attention to the recycling of N containing downstream "wastes". It is, however, naive to assume that even perfect recycling suffices to offer the same number of people the same diet without inputs of "new" N, as inevitable losses of N make compensations indispensable. "New" N can be derived from either biological N fixation ("legumes") or from industrially fixed N ("fertilizer"). The existing literature provides no evidence that the use of N fertilizers is per se unsustainable, as these fertilizers can also be made from renewable forms of energy. Besides, soil health and human health appear sensitive for the dosage but not for the form of N. It is yet imperative to reduce the input of "new" N as much as possible, so as to minimize adverse environmental effects. Measures to this end are a more precise assessment of crop N requirements, a better timing and positioning of N inputs, and any measure supporting the acceptance of "wastes" by farmers. The present paper elaborates the above aspects.

“…Dicyandiamide (DCD) is one of the most widely used bacterio-static nitrification inhibitors in the agriculture (Zacherl and Amberger 1990) and decomposes in soil to non-toxic products (Amberger 1989). Effect of DCD on N 2 O emissions has been reported by de Klein et al (1996) in grass land, Mosier et al (1996) in wheat and maize and McTaggart et al (1994;1997) in ryegrass, grassland and spring barley.…”

An experiment was conducted to assess the role of different concentrations of dicyandiamide (DCD), a potent nitrification inhibitor, on temporal changes in nitrous oxide emission from sandy loam agricultural soil. It was found that with increasing concentration of DCD i.e. from 6 to 12% of nitrogen applied in the form of urea, there was a decrease in the both average and peak N(2)O emissions. However, from 14% DCD treated soil, there was a non-significant alteration in the N(2)O emission. Maximum average N(2)O efflux of 217.55 microg m(-2) h(-1) was noted from control plots. As compared to control, there was an attenuation of 50, 58, 65, and 91% average N(2)O efflux from 6, 8, 10 and 12% DCD applied pots, respectively, whereas, there was a negative average of N(2)O efflux from the soil with 14% DCD treatment. The soil N content also showed a significant correlation with N(2)O emission. Therefore, 12% DCD treatment has been found to be the best with regard to attenuation of nitrous oxide from sandy loam agricultural soils.
