An evaluation of pre-plant deep banding of fertilizer
Non-Peer ReviewedResults of recent field research dealing with methods of
fertilizer application are reported and discussed. Field
work included the use of solution nitrogen (N), N and
phosphate (P2O5) suspensions, and practical alternatives
for the application of granular N and P2O5 fertilizers.
The importance of placement of solution N is illustrated,
compared to post-emergent broadcast application. The
increasingly important dilemma with respect to fertilizer
application under zero or minimum tillage management is
discussed. Thirdly, some of the popular methods of
application of N and P2O5 and the need for starter
P2O5 are discussed in light of the growing number of
alternatives presented to the farmer
Influence of forage fertilization on soil nutrient distribution
Non-Peer ReviewedFew of the field experiments that are carried out in western Canada are designed to test the cumulative impact of annual fertilizer treatments on the soil to which they applied. It is unfortunate that this phase of research is ignored since the application of fertilizer can have a significant influence on soil quality. The potential of nitrogen to displace cations such as calcium and magnesium is one of the common concerns related to fertilizer application. Concerns about the potential of nitrogen fertilizers contributing to contamination of groundwater supplies has also become a major issue in recent years
