19-19-19 All Purpose Fertilizer vs Geolife NPK 19:19:19

Both are the same 19-19-19 NPK blend, so the choice comes down to how you apply it and in what quantity. Geolife is sold as a fully water-soluble powder for foliar spray and fertigation, with a stated dose of 1-2 g per liter. Elk Mound is a general garden and lawn fertilizer in 1 kg, 5 kg and 25 kg bags, and its label lists nitrate, ammoniacal and urea nitrogen plus low insolubles, which suits soil application. For a home garden or a phosphorous-poor lawn, buy Elk Mound. For drip lines, sprayers or hydroponic-style feeding, buy Geolife.

• Choose the Elk Mound 19-19-19 if you are feeding garden beds, lawns or field soil and want a bulk bag you can spread or dissolve yourself.
• Choose the Geolife NPK 19:19:19 if you spray leaves or run a fertigation system and want a fine, fully soluble powder with a clear per-liter dose.
