Planting ‐ Dryland
- ITS DRY, REAL DRY
- Thoughts:
– Be careful chasing moisture
- Only place with good moisture is
heavy cover strip tillage
– (even with striping and planting in same pass)
- 1.5” is deep, only go that deep if
they have rotary hoe or no issue with compaction
– DUSTING IN
- Some say too early, I think depends
upon situation
– This is good time to plant irrigated land
- Make sure they place seed in dry soil
SLIDE 12
Planting ‐ Irrigated
- ITS DRY, REAL DRY
- Thoughts:
– Almost necessity to pre‐water – Once planting occurs, do not let soil dry out
- Irrigations are required almost daily
- Should be able to get stand in less than 4 days
– Herbicide injury
- You can’t have injury unless you have a stand!!
- Get a stand is most important!!
- Injury not always issue for yield!!
- BUT, PRE‐WATER is best way to help and hope to limit to 1‐2
irrigations to get emergence (activate herbicide 24 hrs ahead of emergence)
SLIDE 13
Planting – Soil Compaction
- Tips to assist emergence
– Irrigate repeatedly, keeping good soil moisture – Rotary‐hoe
- 2‐3 days after planting (if crusting)
- Don’t run too late!!
