Which is better for drip irrigation or fertigation?

The Geolife powder. It is 100% water soluble, so it dissolves cleanly and won't clog emitters. The granular Triple 19 is meant to be spread on soil, not run through a system.

Which is better for a lawn?

The Triple 19 granular product. A spreader gives even coverage, and the granules feed gradually after watering. The powder is harder to apply evenly across turf.

Do they supply the same nutrients?

Yes, both are 19-19-19, so the nitrogen, phosphate and potash percentages match. The difference is form, application method and how the nitrogen is split.

The Geolife powder, applied as a foliar spray or through fertigation, is taken up quickly. The granular product releases gradually as it breaks down in the soil.

Is the granular one worth stepping up to over the powder?

Only if you top-dress soil and want no mixing. If you spray or fertigate, the powder is the more practical choice.

Which lasts longer in storage?

Both keep well in a dry, cool place. The granular product comes in larger sealed bags, which suits bigger jobs and fewer restocks.
