This week of cool weather has made it clear that fall is fast approaching. The drop in commodity prices will likely cause a few conversations among farmers, consultants, and retailers on what fertilizer to apply for the 2015 cropping year. Many fields are currently being soil sampled for phosphorus (P), this fall is a good time to consider what is actually out in the field to best target P fertilizer applications.

Because of weather, a number of acres of the 2013 sugar beet crop will
not be harvested. It has been a number of years (PIK years) since this
many acres have been left un-harvested. At that time, SMBSC and the
University of Minnesota did conduct a number of research studies to
answer the main production question: "What should I do with these
fields for next year?"

With spring finally approaching it is a good time to address some
questions on soil testing that came up of the winter concerning testing
soils in a field moist state versus the standard dried samples that are
run through soil testing labs. First I would like to make it clear that
the issue of drying of a soil sample mainly pertains to potassium.
Most other tests routinely run through the lab are not affected by
drying of the sample. The reason why potassium is different is due to
its chemistry in the soil. We currently have finished the second year
of potassium studies looking at both testing methods but will be
continuing this work for the foreseeable future to gain a better
understanding of what is going on within the soil.
