Q.what fertilizer should client apply now for corn and what fertilizer should he apply next year
Gardener grows corn for his own consumption and added nitrogen before planting.He then got a soil test which showed 3.2% organic matter,pH of 5,Bray 1 phosphorus 13 ppm, and K of 45.He was told apply 15-20-40.His corn is coming up slowly.I have researched the topic but most information is for farms,not gardens.Should side dressing be only nitrogen this year when corn is a foot high?Next year should he apply something to neutralize the pH plus
potassium and phosphorus.Thank you.

Corn has only one strict requirement: High nitrogen. This will mean the the soil will be slightly acidic, and contain high amounts of nitrogen. Any high nitrogen fertilizer with no potassium and phosphorus will be needed, as well as applied again throughout the season. Corn are heavy feeders, and will require constant feeding.
