Summary

  • Reford Municipality #379, sections 19,20,30,31 -39-19 W3
  • Located Southwest of the town of Wilkie, Saskatchewan
  • Airport in section 31
  • CPR runs through section 19, 30 and 31

Map Units

Scott Soils

Hanley Soils

Map Units and Slope Classes

  • Dark Brown Solonetic soils
  • Poor agricultural capability
  • Significant soil salinity
  • Neutral to slightly acid
  • Undulating landscape
  • Gentle slopes
  • Loam/Silt-loam surface texture
  • Fair to poor agricultural soils
  • Severe crop limitations
  • Available soils moisture= 75mm
  • Dark Brown soils
  • Slightly to moderate acid
  • Undulating landscapes
  • Gentle to very gentle slopes
  • Very fine sandy loam to silt loam
  • Fair agricultural capability
  • Moderate water holding capacity limitation
  • Surface acidity limitation
  • Capability class 3
  • Available soil moisture= 60mm

Recommended land use: Pasture

Recommendations

Recommendations

Seed to forages of Ryegrass. This will increase organic matter and help draw down moisture.

Orchardgrass and kentucky bluegrass for low lying areas to manage high moisture and salinity.

Seed to salt-tolerant forages: Birdsfoot trefoil, sweetclover and alfalfa

Bromegrass should be seeded around low-lying areas

Avoid summerfallow in recharge areas

Avoid additions of manure as fertilizer

Questions?

Soils in the presentation area have severe limitations to crop growth.

Runway Soils

Scott-Hanley Soils

  • Dark brown and solonetzic soils in North
  • Very gently sloping
  • Fair to poor agricultural capability
  • Limitations moderately severe and very severe
  • Soil salinity, alkalinity and insufficient moisture holding capacity limitations
  • Loam texture
  • Available soil moisture= 70mm
  • Often wet, poorly drained
  • Occasionally stoney or saline
  • Developed in: meltwater channels, spillways or eroded till plains
  • Gentle-steep slopes
  • Usually non-arable
  • Weakly developed
  • Severe limitations for crop productivity
  • Variable surface texture classes
  • Available soil moisture= 70mm

Recommendations

Crop rotation: Legume- Cereal- Legume- Cereal

Crops: Year 1- Field peas (nitrogen fixing)

Year 2- Oats (acid tolerant)

Year 3- Field peas (nitrogen fixing)

Year 4- Barley (drought tolerant)

Deep plowing is recommended to displace sodium in B horizon

Recommendations

Seed to forages: Alfalfa, red clover, and birds foot trefoil

To avoid erosion, reduce conventional farming practices

Kentucky bluegrass and orchardgrass planted around gullies

  • Most land will be used for forages of alfalfa and ryegrass
  • Bromegrass seeded around low lying areas
  • Orchardgrass or Kentucky bluegrass in severely saline areas
  • Withhold use of manure to avoid adding more salts
  • Avoid irrigation
  • Avoid summerfallow

Flat Lake Soils

  • Poorly drained and saline
  • Located in depressional areas
  • Loam to clay-loam surface texture
  • Poor agricultural soils: 5-7
  • Rarely suitable for forage
  • Available soil moisture= 80 mm
  • Not suitable for crops

Recommendations

Seed to forages: alfalfa, red clover, birdsfood trefoil

This will increase organic matter and soil structure and tilth

Kentucky bluegrass and orgardgrass planted around low-lying areas
