Nutrient Requirements of Mixed Forages

This project is demonstrating the importance of balanced N and P fertility in mixed forage stands. Results show that N consistently increases first cut forage yields and that applying P further increases yields, although additional yield increases were small. For example, at one site, a 6 percent increase in response to P was observed compared to N alone. Forages fertilized with N and P also appear to maintain more uniform and vigorous alfalfa in the stand compared to surrounding areas. These results are proving the importance of P fertilizer in mixed forage stands. AB-13
