Burning vs. not burning was examined at 3 nitrogen levels over 6 years (3 crops). Burning had no effect on grain yield or grain N uptake. Burning increased straw yield when wheat was fertilized by N, but had no effect on straw N uptake. Burning did not decrease foot rot incidence or severity, but did reduce downy brome density. T: Effects of stubble burning and N fertilization on grain and straw of winter wheat 1980-85. Effect of stubble burning on foot rot infection. Effect of stubble burning on downybrome infestation.

The best long-term way to control weeds is to get soil nutrients into balance, with relatively high calcium and phosphorus, and low potassium levels. Soaking seeds in hydrogen peroxide solution for 8 hours should increase germination rate. A general foliar feed recipe is given consisting of 1 qt. liquid phosphoric acid, 1 gallon household ammonia, and 2 gallons liquid fish emulsion. A refractometer can be used to monitor crop health. For growing wheat, use sap from the second and third newest leaves. Later, use the flag leaf. A sugar reading of about 18% or above is good. Readings over 25% are excellent and below 8% poor.
