Pasture Fertilization Demonstration Trials
Pasture Fertilization Demonstration trials were conducted from 2008 through to 2011. The primary purposes of these demonstration trials were:
Overall the trials were a success! At both sites, the increase in forage productivity from the cattle and horse manure applications was equal or greater to the chemical fertilizer. Although the 34-0-0-11 fertilizer performed well, the custom fertilizer outperformed it by the end of the trial. The results of the demonstration trial were definitely impacted by the weather. Both of the 2009 and 2010 growing seasons were relatively hot and dry, limiting re-growth of the pasture forage. Soil testing at the end of the trial indicated that both sites were still very nitrogen deficient. If these pastures are going to be used extensively, additional fertilizer is recommended to achieve optimal pasture productivity. When this is not economically feasible, rotational grazing would more evenly distribute the nutrient deposition from manure and urine. The positive impact that the livestock manures had on the forage vegetation really emphasized that using manure as a fertilizer may ultimately increase pasture production, and thus improve overall economic viability. |
