Other claims from this paper (7)
- Intervention effect Establishment-year yields from manure and fertilizer treatments were equal to or greater (0–103%) than the control yield at all sites.
- Intervention effect Production-year yields were similar for manure and fertilizer on soils testing very high in P and K.
- Intervention effect On medium-testing soil, responses to fertilizer and manure treatments were similar.
- Association Herbage K concentrations increased in direct proportion to the rate of manure or fertilizer applied.
- Association Herbage P concentrations were generally not affected by fertilizer or manure additions.
- Intervention effect Preplant manure applications gave alfalfa yield increases similar to commercial fertilizer additions where fertilizer would be recommended.
- Observation Preplant manure application was not detrimental to alfalfa production.
