Maximum yield potential is normally set for spring cereals during the first 35 days after emergence, a time when the crop roots are too shallow to reach deep nitrogen. Water saturated soils also are slower to warm up which further reduces nitrogen availability. When soils are saturated with water, they dry slower and often are tilled before they should be. Tilling soils that are too wet leads to compaction and problems throughout the growing season. Probe the soil profile and do not be fooled by the appearance of the top couple of inches.
Compacted soils restrict root growth and nutrient absorption and result in lower yields.
These effects often persist over several crop seasons. Identity preserved marketing Identity preserved marketing of specific varieties has been occurring in malt barley for many years. This type of marketing is just catching on with wheat but holds promise of added returns for producers who use it. The first consideration in entering this market place is whether the variety you are going to plant is one that is in demand. Secondly, consider the risk if grade specifications are not met, what is the alternative market.
