Management for Agricultural
Land Uses
 Part 4 of soil scorecard
 Worth the most points at each land area
 You will be told how many to mark
 Should relate to soil problems (part 2) and to the
agricultural land use (part 3) that you selected.
Management Practices

Grass Waterways (Fig. 20-14: p. 283)
Water course or drainage way protected against erosion
by grass cover
Select when there is a water erosion, seasonal flooding,
or permeability problem and the area is being used for any
rotation including row crops
 Contour tillage
Plow, plant, and cultivate on the contour (opposite angle)
of the slope (go across the hill instead of down the hill.
Select with any water erosion problem and the area is
being used for any non-tree crop.
Management Practices
 Strip Cropping (Fig. 20-13: p. 283 of book)
Planting a field with strips of crops to create
vegetative barriers that reduce erosion.
Not used in our area of the state (Do NOT mark)
 Conservation tillage
Using the least amount of tillage necessary to
obtain a good germination (growth of seed)
Leaves maximum of crop residue (waste) on the
soil to reduce soil erosion
Select anytime there is a non-tree crop being
grown
Management Practices
 Terrace or diversion (Figure 21-14, p. 297)
Terrace is an earthen ridge that “stair steps” a steep
slope
Diversion is a channel running across a slope to
carry water to a grass waterway
Usually not used in our part of the state (Do NOT
mark)
 Windbreaks / vegetative barriers
Using plants (trees or tall grasses) to block wind
Select if there is a wind erosion problem and the
area is being used for any row crops
Management Practices
 Install / maintain artificial drainage
Select if soils have a drainage or seasonal
flooding problem and are used for any non-tree
crop
 Barnyard manure
Select if:
– Manure is available
– The area is being used for non-tree crops
– The Phosphorus level is less than 300 lbs. per acre
Management Practices
 Liming Materials
Used to raise the soil pH
Select if the soil pH is 6.5 or lower
Or select if growing legumes with 6.8 or lower
 Apply phosphorus (P) fertilizer
Select if there is 79 lbs. or less of phosphorus per
acre
 Apply potassium (K) fertilizer
Select if there is 299 lbs. or less of potassium per
acre
Management Practices
 Cover and Green-manure crops
Select if:
– Area is being used for orchard crops
– Area has a soil erosion or an organic matter problem
 Return all crop residues to the soil
Always mark if area is being planted in a non-tree
crop
Management Practices
 Establish and/or maintain legume-grass mixture for
continuous sod crops
Select if:
– Area is being used for continuous sod crops
– Area has a severe erosion problem
 Establish and/or maintain grasses for permanent
cover
Select if:
– Area is being used for continuous sod crop
– Area is a wet land area (Seasonal flooding or wet
spots)
Management Practices
 Managed grazing for pasture erosion control
Select if area is being used for a continuous sod
crop
 Topdress established legumes with phosphorus
Select if:
– Land use is a rotation including legumes being planted
for ½ to full time (options 2-5 on scorecard part 3)
– Phosphorus level is 79 pounds or less per acre
Management Practices
 Topdress established legumes with potassium
Select if:
– Land use is a rotation including legumes being
planted for ½ to full time (options 2-5 on
scorecard part 3)
– Phosphorus level is 299 pounds or less per acre
 Topdress permanent vegetation with commercial
nitrogen
Select if area is used for continuous sod crops
Management Practices
 Eradicate brush
Select if:
– There are brush or shrubs present
– The area is being used for continuous sod crops
 Special plantings for wildlife food and cover
Select if continuous sod crops or woodland is the
selected use
 Plant adapted species of trees
Select if woodland is the selected use
Management Practices
 Protect trees and shrubs from grazing or burning
Select if area is being used for woodland or
orchard crops
 Manage woods
Select if the area is being used as a woodland
