Forage Rejuvenation with Phosphorus Fertilizer

Evaluate the management of dry and fluid P fertilizers, applied with N fertilizer, to restore the productivity of low producing forage stands in Saskatchewan.

IPNI-2003-CAN-SK35

Established forage stand productivity is seriously limited by nutrient supply in most areas of western Canada. While only limited acres of forage crops are fertilized, past research has shown it to be one of the most responsive crops to N application. Soil P depletion is often the factor that leads to low stand productivity, with the forage crop extracting all of the plant-available P from the soil, limiting N response. Read more

Interpretive Summary

2004

Forage Rejuvenation with Phosphorus Fertilizer, 2004. Established forage stand productivity is seriously limited by nutrient supply in most areas of western Canada. While only limited acres of forage grass crops are fertilized, past research has shown it to be one of the most responsive crops to nitrogen (N) application.
