“…Other studies have shown relatively low recovery of manure nutrients in forages. Apparent N recovery from liquid and solid dairy manure applied at 150 kg N ha −1 to orchardgrass ( Dactylis glomerata L.) during 2 yr was 40% for liquid manure and 26% for solid manure (Kanneganti and Klausner, 1994). Apparent N recovery from dairy slurry applied to a bermudagrass–ryegrass ( Lolium multiflorum Lam.)…”

Manure use on cropland has raised concern about nutrient contamination of surface and ground waters. Warm-season perennial grasses may be useful in filter strips to trap manure nutrients and as biomass feedstock for nutrient removal. We explored the use of 'Alamo' switchgrass (Panicum virgatum L.) in a biomass production-filter strip system treated with dairy manure. We measured changes in extractable P in the soil, NO3 -N in soil water, and changes in total reactive P and chemical oxygen demand (COD) of runoff water before and after a switchgrass filter strip. Five rates of dairy manure (target rates of 0, 50, 100, 150, and 200 kg N ha(-1) from solid manure in 1995; 0, 75, 150, 300, and 600 kg N ha(-1) from lagoon effluent in 1996 and 1997) were surface-applied to field plots of switchgrass (5.2 by 16.4 m) with a 5.2- by 16.4-m switchgrass filter strip below the manured area. Yield of switchgrass from the manured area increased linearly with increasing manure rate in each year. Soil water samples collected at 46 or 91 cm below the soil surface on 30 dates indicated < 3 mg L(-1) of NO3-N in all plots. Concentrations of total reactive P in surface runoff water were reduced an average of 47% for the 150 kg N rate and 76% for the 600 kg N rate in 1996 and 1997 after passing through the strip. Manure could effectively substitute for inorganic fertilizer in switchgrass biomass production with dual use of the switchgrass as a vegetative filter strip.

“…Manure cannot supply all the N needed when very high rates of N fertilization are required, because plant recovery of manure N can be as low as 13% (Kanneganti and Klausner, 1994). We assumed that manure could be used for the our study, but the calculation of N imported flable 3) does allow for simple comparisons of species and management effects.…”

Cherney, D.J.R. and Cherney, J.H. 1997. Grass forage quality and digestion kinetics as influenced by nitrogen fertilization and maturity. J. Appl. Anim. Res., 11: 105-120.Objectives were to assess the influence of N fertilization of reed canavgrass and timothy on fiber and N partitioning, digestion kinetics and on model-predicted quality. Four replicated field plots of each grass received one of jive levels of N fertilization (0, 67, 90, 135 and 269 kg of N / h ) aizd grasses were evaluated at first-cutting in 2 yr. Fertilization with N affected fiber composition quadratically both years. Rate of in vitro NDF digestion increased two fold when forages were fertilized with 269 versus 0 kg of N / h , ranging from .041 to .087/h in 1994 and from .047 to .078/h in 1995. Crude protein increased linearly with increased N fertilization (from 9.9 to 21.7 % and from 11.9 to 22.3 % in 1994 and 1995, respectively). Neutral detergent insoluble fiber decreased from 26.5 to 18.0% and from 27.5 to 21.0 % as N fertilization increased from 0 to 269 k,g of N/ha in 1994 and 1995, respectively. Because of higher total CP, reed canarygrass diets balanced with less soybean meal than timothy when fertilized with 0 and 90 kg of N/ha. With grasses fertilized with 269 kg of N/ha, however, CP in grasses exceeded requirements and more timothy could be used in the diet than reed canarygrass. Although total CP was lower in timothy, neutral detergent insoluble protein was higher than in reed canarygmss. The Cornell Net Carbohydrate and Protein System model predicted forage species, harvest and fertility management will resdt in differences in milk production. These factors need to be considered when making management decisions.

“…1999). Cultivating crops that could potentially take up a large quantity of N from the soil is an option to mitigate the impact of high N inputs on the environment (Kanneganti and Klausner 1994). Among the various factors that could be influenced by human activities, N is the one that could affect the performance of crops in the most dramatic way.…”

In Japan a high dependency on imported food, particularly livestock feed, has resulted in the accumulation of large amounts of nutrients, especially nitrogen, in the form of livestock manure. Cultivating feed crops that can take up a large amount of N would not only mitigate the water pollution caused by the nitrate leached from the livestock sector, but would also improve food self sufficiency. Sugarcane (Saccharum spp.) is considered to be a promising candidate in this respect. Two field experiments were conducted in 2006 and 2007 in Kagawa to evaluate the dry matter (DM) yield, N content and nitrate‐N concentration of sugarcane under high N input. The first experiment was designed as a factorial experiment with two factors, varieties/lines/clones and N rates set at two levels, 30 g m−2 year−1 and 60 g m−1 year−1, with three replicates. In the second experiment, 30 varieties/lines/clones of sugarcane and related genera as well as control crops were planted (n = 2) and a single N rate of 45 g m−2 year−1 was applied. Some varieties/lines of sugarcane produced an above‐ground DM yield greater than 4.0 kg m−2 and contained more than 40 g m−2 of N in the above‐ground part. Erianthus clones, IK76‐126 and IJ76‐349 tended to accumulate nitrate‐N when high rates of N were applied. No sugarcane varieties out of the 28 varieties/lines tested in the present study accumulated nitrate‐N beyond the allowed limit for feed use, irrespective of the N rates tested in the experiments. The ability of sugarcane not to accumulate nitrate‐N under conditions of high N input was considered to be an advantage in double‐purpose cultivation; that is, sugarcane can be used as a feed and cleaning crop.
