If I want to use MTM in my manure this fall, can I dump it into my pit 2-3 days before its applied and still have a benefit or do I need to wait 2 weeks after adding MTM to my pit? Can I dump MTM directly into each tank load at application time, if I want to try the product on my farm this fall?

MTM will protect the nitrogen and phosphorus from the time of application, whether it be applied in the pit/lagoon or directly in manure tanks before going to the field. If you’re applying MTM to a pit/lagoon within 14 days of when you want to pump out the pit/lagoon, agitation is required to ensure MTM is thoroughly dispersed.

Depending on the specific geographic region in question, this date may range from… Read Full Answer

With corn prices as high as they currently are and likely will be next year, I recommend not taking a chance on anything that could be yield limiting in 2013. If you use your soil test P as a guide, you may notice little or no change in the test from earlier samples. If the soil P test comes back high, I would recommend using a starter fertilizer. If you band fluid starter in a 2x2… Read Full Answer
