Soil and Plant Responses to Long-Term Fertilization of Alfalfa (Medicago sativa L.)1
- D. K. Markus and
- W. R. Battle2
Yields and persistence were greatly increased by K fertilization over a period of 9 years. Yields were not affected and persistence was reduced by N and P. P concentration in alfalfa hay was dependent on rainfall rather than on the P fertilizer. Levels of soil K and P supplies were considerably influenced by K and P. Continued alfalfa production was largely dependent on the relative abundance of K provided by fertilization. P from the soil supply was sufficient for maximum yields, but supply was depleted without application of P.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
