kernel, blocking movement of dry matter and nutrients from the plant to the kernel (50 to 60 days after R1). Kernels achieve maximum dry weight (30 to 35% moisture) and are physiologically mature. Management Grain is not ready for safe storage. Frost or any biotic or abiotic stress does not impact yields after this development stage.

Uneven Emergence in Corn (NCR344)
corn.agronomy.wisc.eduThe most common cause of uneven emergence in corn is dry soil. If the soil is too dry at or shortly after planting, seedlings will emerge at different times. Emergence time may vary between parts of fields, from one row to the next, or from one plant to the next. Soil moisture can differ within a field

Soil Calcium to Magnesium Ratios—Should You Be …
corn.agronomy.wisc.edurange. The Ca:Mg ratio seldom will be the dominant factor determining calcium and magnesium uptake by plants. This was shown by the small variations in the tissue Ca:Mg ratio when the soil Ca:Mg ratio was varied (table 2). Table 2. Effect of varying Ca:Mg ratios on yield and calcium and magnesium levels in alfalfa.
