Presented in the panel discussion on U.S. Fertilizer Demand and Nutrient Use Issues at the Fertilizer Outlook and Technology Conference held in Jacksonville, Florida on 10 November 2015.

22 May 2015United States Corn: Fertilizer Use Efficiency Doubles between 1980 and 2014

Fertilizer use efficiency has many definitions. One of the most useful is "partial factor productivity" (PFP). The following four charts show trends for PFP for nitrogen (N), phosphorus (P), and potas ...

Nova Scotia, New Brunswick, Prince Edward Island

06 Mar 2014Crop Nutrient Balance - Quebec - Potassium

Potassium (K), like phosphorus, is relatively immobile in the soil and tends to accumulate when applied in surplus, except on the sandiest soils. In most of the past 40 years, the amount of K applied ...

06 Mar 2014Crop Nutrient Balance - Quebec - Phosphorus

The phosphorus (P) balance shows a substantial surplus during the years when producers were building up soil fertility. The surplus is smaller in the past 8 years than at any time in the past 40 years ...

06 Mar 2014Crop Nutrient Balance - Quebec - Nitrogen

Since nitrogen (N) is a mobile nutrient, producers focus on matching crop uptake requirements as closely as possible. Applying N in surplus to crop needs does not build up a reserve in the soil. Howev ...

Potassium (K), like phosphorus, is relatively immobile in the soil and tends to accumulate when applied in surplus, except on the sandiest soils. In most of the past 40 years, the amount of K applied ...

06 Mar 2014Crop Nutrient Balance - Ontario - Phosphorus

The phosphorus (P) balance shows a substantial surplus during the years when producers were building up soil fertility, up to the early 1990s. The historical surplus has contributed to the higher fert ...
