Cost of a bag of fertilizer

I noticed a comment from my friend Patti... She was asking how much a bag of fertilizer costs?

The best type - that seems to work best here - is a pre-emergent.  It is called "Formula" and at the moment it costs about $59 per 220 pound bag.  This is about enough for one 'manzana' (almost 2 acres) of land. 

There is another type that is applied about a month after planting ... it is called Sulfato and costs about $40 per bag.  This is not nearly as effective as the Formula.  When people can, they use both. 

These prices change every Monday.  Last year in April, they were $78 for Formula and about $56 for the Sulfato.  I think the prices rise the closer it comes to planting time. 

Most people don't think this far ahead to take advantage of the lower prices.  We did only because of St. Boniface in Waukee (hope they don't mind me naming names!!).  They wanted to buy fertilizer for their partner community.   And that is when we discovered the much lower prices in January. 

Thanks for asking Patti!!
