Effect of Broadcast versus Banded Phosphorus Application on Fate of Applied P in Soil and in Snowmelt Water Flow

IPNI-2014-CAN-4RC07

Objective: To determine the fate of phosphorus (P) applied as broadcast versus banded application method to a prairie soil. The agronomic and environmental benefits of a key aspect of 4R Nutrient Stewardship, right fertilizer placement, will be revealed in this research. Timing of application and the effect of rate of applied phosphorus is also covered. Read more

Interpretive Summary

Phosphorus (P) moves very slowly in soil and is often called immobile. In soils that are deficient in P, it is important to place the P so that the roots of the crops grow into the area where the P fertilizer is placed. The objective of this study is to compare various P fertilizer placement methods in relation to the seed row.

Phosphorus moves very slowly in soil and is often called immobile. In soils that are somewhat deficient in P, it is important to place the P so that the roots of the crops grow into the area where the P fertilizer is placed. The objective of this study is to compare various placements of P fertilizer in relation to the seed row.

There is interest in the impact of P fertilizer placement on crop recovery, and fate of the applied P in the soil, and in run-off water. This research will evaluate the influence of methods of placement of mono-ammonium phosphate (MAP) fertilizer on the yield and recovery of phosphorus by soybean, in a typical Western Canadian soil. A farm field (wheat stubble) was selected in the spring of 2014 in the Dark Brown soil zone near Central Butte, Saskatchewan.
