A common problem across many slurry storage systems is the growth of thick crusts over the period of a couple of years.
This usually occurs in tanks or stores where the crust isn’t totally eliminated during mixing and where the surface is exposed to a lot of wind. As a result over the years an unmanageable crust forms.
Last year Mark Crawford was asked to look at one such example in a large slurry store. With a capacity of over one million gallons, a “crust plug” had formed which simply moved up and down as the store was filled and emptied. Over the years this had grown to over 1 foot in thickness.
Slurry Gold was added at the start of the season (September 13 – Image 1) and subsequently each month as the store was filled. Immediately the bacteria and enzymes got to work and within a few months cracks and bubbles started to appear (Jan 14 – Image 2). By the time the tank was ready for emptying, the crust had virtually disappeared and the store could be emptied with minimal mixing (March 14 – Image 3).
“In this case Slurry Gold had sufficient time to completely remove the crust,” stated Mark Crawford.
“Many farmers ask me when is the best time to treat the tank. The simple answer is as soon as possible in particular where thick crusts are involved. The more time the microbes have to work the better.”
It is important that farmers think now about treating their tanks to maximise the returns come spring time. Not only will it mean less mixing, but improved Nitrogen uptake and better soil conditioning in the longer term.
