One grower in 2017 saw a 40 bu/ac yield difference with the same hybrid between two planting dates only 2 days apart.
Wait to plant – Wet conditions are the number one cause of soil compaction! Wait for drier conditions to plant as much as possible. These tips can help reduce sidewall compaction on your farm for the 2018 season. Managing sidewall compaction from the beginning is an important step in maintain high yield potential in your corn crop. As a result, the plants access to necessary water and nutrients is restricted. The compaction zone becomes increasingly hard as the season progresses and becomes drier. The water acts like lubricant for soil particles and helps to pack them together. Planting into wet conditions are the number one cause of sidewall compaction. Springs that are wet followed by summers that are exceptionally dry are much more likely to see the yield robbing power of sidewall compaction. This can seriously reduce yield potential as a result.
Restrictions on root growth will have season long impacts on the corn plant. This makes it highly susceptible to sidewall compaction. Sidewall compaction occurs when the soil structure of the seed trench has been compromised and tightly compacted due to a combination of mechanical pressure and field moisture.Ĭorn has a fibrous root structure. The 2017 growing season saw growers facing many yield robbing factors but an extremely common issue was sidewall compaction.
