Nitrogen recommendation = 1.5YG - STN - LC
Bray-1 P recommendation = (0.785 - 0.039 STP)YG
Olsen P recommendation = (0.785 - 0.05 STP)YG
Potassium recommendation = (1.286 - 0.0085 STK)YG

Malting Barley Statements:

  1. When P2O5 is recommended:  The P2O5 recommendation can be reduced by one third if applying as a starter.  If reduced by one third, soil test levels may be lowered over time.
  2. Because of your very reduced or no tillage system, 30 lb/a of additional nitrogen has been considered in the above N recommendation.

  3. When nitrogen and / or potassium are recommended:  Nitrogen plus K2O fertilizers should be limited to 25 lbs/a when placed in contact with the seed in 6 or 7-inch rows.  Reduce these values correspondingly for wider row width.  Reduce these amounts by half for dry or coarse textured soils.  DO NOT place thiosulfate in direct contact with the seed.
  4. Malting Barley with no 0-24" nitrate test:  To increase the probability of obtaining malting barley grade, a two-foot deep sample for the nitrate nitrogen test should be taken.
