Note that just because two liquid fertilizers will mix together doesn't necessarily mean that it is a good idea to mix them.

Liquid fertilizer blends involving micronutrients can result in some very unique messes that may look like shaving cream or axle grease.

Before blending a truckload, do yourself a favour and mix some up in a quart sealer. Let it sit for a few days to see what happens.

Even when the quart sealer test works, blending larger batches can have exciting results. 10-34-0 can be particularly problematic

in a multi-nutrient micro blend.
