Soil Evaluation For Desirable And Detrimental Properties
Soil Health Property |
Healthy |
Unhealthy |
Corrective Action |
| plant appearance |
lush, uniform, dense, tall, large, sturdy, proper color |
yellow, stunted, small, poor color, light green, spotty |
Correct soil problem or test plant for needed actions |
| soil structure |
crumbly, loose, holds together, granular |
hard when dry, doesn't hold together, lumps fall apart, massive, cloddy, clumpy, tight, compacted, powdery |
Amend and condition to increase physical properties |
| roots |
large, branches and spreads out, white, grows downward, numerous, good penetration, lots of feeder roots |
won't penetrate, undeveloped, balls up, grows crossways, discolored, diseased, shallow, short |
Amend and condition to increase physical properties |
| soil color |
dark, black, dark brown, gray, holds dark color when dry |
orange, brown, light, white, red blue-gray, bleached, sandy color, light brown, pale, anemic |
Add organic matter |
| water infiltration |
water does not stand, absorbs, water moves into soil, soaks, rapid, no ponding |
water runs off soil, sits on surface, water stands, won’t absorb, puddles, nonporous |
Amend and condition to increase physical properties |
| compaction |
doesn't pack down, not compacted, remains loose |
compacted, hardpan, tight, packed, difficult to till |
Till, amend and condition |
| earthworms |
many present after rain or irrigation, holes and castings present, found during tillage |
not present, no holes |
Correct soil chemistry and/or correct physical problems, add organic matter |
| erosion |
soil will not erode, remains in place |
blows away, washes away, erodes, causes dust clouds, rills present |
Amend and condition |
| drainage |
water disappears quickly, no ponding, soil dries out quickly |
tight, waterlogged, ponding, saturated |
Amend and condition to increase physical properties |
| ease of tillage |
breaks up in one pass, mellow, smooth, crumbles, minimum amount of effort needed |
clods don't breakdown, lumpy after tillage |
Amend and condition to increase physical properties |
| water retention |
holds moisture, gives and takes water freely, excessive irrigation not needed |
has too much water, doesn't hold water, either too wet or too dry, droughty, remains wet |
Remove surface crust or improve physical properties |
