Dry land Crop Rotation

  • Winter Wheat-Corn-Field Pea
  • 2/3 of rotation is planted to high

residue crops. Need high amounts of residue to improve water infiltration and lower soil moisture evaporation.

slide-5
SLIDE 5

IRRIGATED CROP ROTATION

  • Winter wheat, corn, dry

edible beans (pinto beans)

  • 2/3 high residue crops
  • Water infiltration and lower

soil moisture evaporation

Soil Types

  • Valent Fine Sand
  • Water Holding Capacity- .96 inches/foot
  • Keith and Alliance Silt Loam
  • Water Holding Capacity- 1.8 inches/foot
  • Our problem is these soils are only 2 feet

deep, with a layer of white calcareous soils underneath

slide-7
SLIDE 7

Challenges

  • Soils have low water holding

capacities 4-6 inches

  • High Evapo-Transpiration rates
  • Rapidly Declining Groundwater
  • Water Allocations-
  • 13.5 in./year

Challenges

  • Hydrologists estimate 5-8 inch

pumping allocations per pivot to stop groundwater decline

  • If groundwater pumping isn’t

reduced we’ll lose 80% of our irrigated acres in 30-40 years

YOU HAVE TO START BY MANAGING YOUR SOIL!

slide-12
SLIDE 12
  • Focus on Soil Quality
  • Increased soil organic matter

leads to good soil aggregation and increased pore space in soil

  • Use previous crop’s residue to

improve water infiltration and reduce soil moisture evaporation

WATER CONSERVATION

  • GOAL OF EVERY PRODUCER-ZERO

GROUNDWATER DEPLETION

  • GOAL IS ATTAINABLE WITH:
  • NO TILL CROP PRODUCTION
  • 2/3 ROTATION HIGH RESIDUE

CROPS

  • SOIL MOISTURE MONITORING

FORAGE/COVER CROP GOALS

  • Manage Residue- turn residue

from high Carbon-Low Nitrogen into High Nitrogen- Low carbon

  • Improve early spring growth

in corn

slide-35
SLIDE 35

FORAGE/COVER CROP GOALS

  • Improve organic matter

content of soil

  • Improve diversity and

populations of soil microbes

  • Improve soil health
slide-36
SLIDE 36

FORAGE/COVER CROP GOALS

  • Reduce dependence on

commercial fertilizer

  • Forage for cattle
  • Concern- 5 inches of irrigation

to grow cover crop
