Part 1 – Land Class Factors
Surface Texture Course = gritty, individual grains can be felt (SAND) . Sand Silt Clay 1
4
Surface Texture (cont…)
Medium = slightly gritty feel or a soft smooth feel like powder (Silt) . 1
5
Surface Texture (cont…)
Fine = fine texture forms very hard clots when dry and is plastic when moist, forms 1” ribbon (Clay). . 1
6
. B. Permeability Very Slow – fine subsoil very
plastic and sticky (Clay) has few small pores which water and air move. . 4 2 1 3
7
B. Permeability (cont…)
Slow – medium or fine subsoil that is slightly sticky and firm when wet and crack into hard fragments when dry, has moderate small pores which water and air move. . 4 2 1 3
8
B. Permeability (cont…)
Moderate – medium textured subsoil, slightly sticky when wet and is crushed with moderate pressure, has large number of fine and medium pores which water and air move. . 4 2 1 3
9
B. Permeability (cont…)
Rapid – has coarse texture, sandy gravelly, or stony, very friable moist, and single grained when dry. 4 2 1 3 .

C. Depth of Soil Deep = 40” or more Moderately Deep = 20 – 40”
Shallow = – 20” Very Shallow = less than 10” 1 3 6 40”< 20-40” 10-20” <10”
11
D. Slope The slope will be taken at either 50’
1 2 3 4 6 7 0-2% 2-5% 5-8% 8-12% 12-17% >17% The slope will be taken at either 50’ or 100’ they will tell you which one.
12
E. Erosion Very Severe = gullies are less than 100’ apart
2 3 7 6” < topsoil 2-6” topsoil 0-2”topsoil No topsoil Very Severe = gullies are less than 100’ apart Severe = gullies are more than
13
F. Soil Drainage Poor = soils have dominant gray color
(over 50%) in the upper 10”. Fair = has gray between 10 and 30” Good = free from gray to 30” Excessive = coarse, free from gray to 40 or more inches. 3 2 1
14
G. Soil Properties Flooding
1 2 3 4 None = could not flood Protected = dike or levy Rare = unlikely but possible under unusual weather Occasional = expected infrequently Frequent = likely under usual weather conditions
15
H. Shrink-Swell Low = soil that is coarse or medium texture
(Sand and Silt) Moderate= soil that has some clay but does not show deep cracks when dry High = deep cracks when dry, evidence can be seen in subsoil. 1 2 3
16
I. Rock Rocks are coarse fragments grater than
3 inches in diameter. For lawns and landscapes only consider the top 4” of soil. 1 2 3 4

K. Problem Areas Place an “X” in the blanks beside
each area according to the findings. If all the areas are slight the problem area will be NONE. X X
22
. K. Problem Areas If there is a moderate the problem
area will be the highest write in number (to the left on front side). (8 – 12%) . 1 2 3 4 6 7 X X
