Bio - Sul

[SASKFARMER3]

Is that what they are spreading near Foam lake?

I wanted to get some applied, but there is no one available in north east Saskatchewan. They wanted me to buy a spreader to do my own. I was game until I priced one out, holy hell are they expensive.

My understanding is that they use chunky raw sulphur. The bugs in the compost do a great job of dissolving some of the raw sulphur and you get a real nice amount available immediately. The problem comes once spread in your field. These large lumps of raw sulphur do not break down very readily.

My take on it is that you will have much more sulphur released from surface spreading an elemental product like T90 over the 10 year term than you will with the bio-sul, because the T90 is all ground to microscopic proportions. Short term with T90 you could have a shortage of sulphur in your crop.
