Two experiments were conducted in two consecutive years. Exp. 1 (2008) was aimed at examining the effects of fertilizing three 1-ha fields with fresh dairy manure that was either weed contaminated (CM) or non-contaminated (NCM), as compared to chemical fertilization (CF). Five 10-m 2 subplots in each field treatment were analyzed for yield, composition, and in vitro digestibility of forage mass, wheat and weed plants, and changes in soil properties. Higher forage wheat yields were obtained in the CM and NCM treatments (9.45 and 9.41t dry matter (DM)/ha, respectively) than in the CF treatment (7.56tDM/ha, P<0.05). None of the field treatments included herbicide application, and all fields were highly contaminated by weed mass (419-580g/kg DM). Weed profile in the three field treatments was similar to that observed in neighboring fields. Sheep intake of diets containing 900g/kg wheat hay was highest in the NCM treatment, lowest in the CM treatment and intermediate in the CF treatment. Digestibility of dietary DM by the sheep followed an opposite trend, but neutral detergent fiber (aNDFom) digestibility was similar in the three treatments (0.64-0.66). Exp. 2 (2009) measured the cumulative effect of fresh dairy manure fertilization applied at two levels, 60 and 120m 3 NCM/ha (designated 60-NCM and 120-NCM, respectively), with CF as the control treatment. The three fields were sprayed with herbicide to reduce weed contamination (<20g/kg). Wheat yield was higher in the 120-NCM treatment (14.5tDM/ha) than in the 60-NCM and CF treatments (12.5 and 12.6tDM/ha, respectively). Sheep intake of rations based on wheat hay from the three treatments was similar (781g DM/d). Digestibility by sheep of DM and crude protein were higher in hays from treatments 60-NCM and 120-NCM than from the CF treatment. Pathogenic bacteria, including Escherichia coli and Salmonella, did not survive in either the soil or the wheat plants during the growing seasons. The increase in wheat yield and digestibility due to dairy manure fertilization was related to the improvement in soil water retention and nutrient availability following this treatment. Adoption of this technology is expected to increase net profits in the dairy industry. © 2011 Elsevier B.V.
