Manure generated from hog farming can be a beneficial soil amendment for agricultural crops, since it is highx000D
in both nitrogen and phosphate. However, most of the phosphate is insoluble, and since the application regimex000D
is based on nitrogen content, much of this insoluble phosphate accumulates over time. This limits the amountx000D
of hog manure that can be applied. In Manitoba, fields near hog farms have reached the limit of allowablex000D
added phosphate, and the transport of manure any great distance becomes cost prohibitive limiting itsx000D
application to a wider region. While insoluble phosphorous can be effectively solubilized using chemicalx000D
acidification with sulphuric acid, mobilization of insoluble phosphorous to crop plants is often inefficient,x000D
reducing phosphorous removal into crop material and reducing potential crop yield. Manure solids left behindx000D
from the acid phosphorous solubilization step can serve as a soil conditioner and if supplemented withx000D
phosphate solubilizing, growth promoting bacteria can act as a source of beneficial bacteria for in situx000D
phosphate solubilization and mobilization to field crops. In the previous Engage grant, we have shown twox000D
strains of Pseudomonas sp. isolated for KGS Engineering are effective at solubilizing calcium phosphate atx000D
near neutral pH and have some efficacy in promoting plant growth in pure culture and in initial growthx000D
chamber studies using canola seeds and seedlings. The purpose of the current Engage+ proposal is to comparex000D
the plant promotion capabilities for plant associated phosphate solubilization as well as further growthx000D
promotion capabilities using Manitoba-relevant seed crops, with a focus on canola, and corn.
