INDIVIDUAL TEST KITS
In addition to the
combination outfits for agricultural and
turf soils, a selection of single parameter test kits
is available for soil nutrients that may be of particular
interest or a problem to the grower.
All OMEGA® soil test kits measure the portion of soil
nutrients available for the plant to use. Since extraction
not complete, the amount that is measured is relative and
is dependent on the extraction procedure. Pounds per
acre represents the number of pounds of soil in an acre
down to the depth of 6-7 inches, and is = 2,000,000 lb.
Conversion from pounds per acre to parts
per million is accomplished with the following
formulas:
ppm x 2 = lb/acre
lb/acre x 0.5 = ppm
A number of variables must be considered when
interpreting soil test results in addition to the values
obtained. These variables include the composition of the
soil, drainage, climate, previous fertilizer programs, and
the type of plant to be grown. Samples must also be truly
representative of the area being studied and must be
carefully selected.
HUMUS
Humus is organic matter which has decomposed to the point that it releases nutrients which are then
available for plant uptake.
|
| Model No. | Method | Range & Sensitivity | Reagent System | # of Tests |
| ITK-5012 | ColoRuler,
filtered extraction | Low to high in 5 increments,
1 1/2-8% | EDTA | 50 |
| R-ITK-5012 | Reagent refill kit | | | |
NITROGEN
Nitrogen promotes above-ground growth and produces the rich green color in leaves. Deficiencies are
characterized by chlorosis and can lead to insufficient growth of seed and vegetation.
|
| Model No. | Method | Range & Sensitivity | Reagent System | # of Tests |
| ITK-5420 | Color chart,
filtered extraction | 10, 20, 40, 100 lb/
acre nitrate N | Cadmium reduction,
2 reagents | 50 |
| R-ITK-5420 | Refill reagent kit | | | |
pH
The pH value affects all mineral elements and the biological processes that can be performed by plants in the soil.
Accurate pH testing is essential to determine lime requirements and to insure that a mineral-rich soil is also fertile.
|
| Model No. | Method | Range & Sensitivity | Reagent System | # of Tests |
| ITK-5023 | 5 Color charts & spot
plate Morgan method
(Not for heavy clay) | pH 3.8-8.4 in 0.2
increments | 5 individual pH indicators | 50 |
| R-ITK-5023 | Reagent refill kit | | | |
| ITK-5024 | Color chart &
spot plate | pH 4.0, 5.0, 6.0,
7.0, 8.0 | Duplex Indicator | 100 |
| R-ITK-5024 | Reagent refill kit | | | |
PHOSPHORUS
Phosphorus stimulates early root formation, gives a vigorous start to plants, hastens maturity, stimulates blooming
and aids in seed formation. Symptoms of deficiency include stunted growth, leaf abnormalities, and even dead
areas. Available nitrogen and soil pH in the range of 6.0-7.0 provide optimal conditions for the uptake of
phosphorus.
|
| Model No. | Method | Range & Sensitivity | Reagent System | # of Tests |
| ITK-5025 | Color chart,
filtered extraction | 10, 25, 50, 75, 100, 150,
200 lb/acre phosphorus | Ammonium Molybdate,
3 reagents | 50 |
| R-ITK-5025 | Reagent refill kit | | | |
POTASSIUM
Potassium is responsible for producing strong, stiff stalks, increased plumpness in grain and seeds, and is
essential to the development of chlorophyll. It is vitally important for increasing disease resistance. Symptoms of
deficiency include “burning” along leaf edges, inadequate root development and weak stems or stalks.
|
| Model No. | Method | Range & Sensitivity | Reagent System | # of Tests |
| ITK-5096 | Direct reading
turbidity tube | Low-high 120-200 lb/acre | Tetraphenolboron,1 reagent | 50 |
| R-ITK-5096 | Reagent refill kit | | | |
TEXTURE
The overall texture of a soil affects growth in the root zone, which determines above-ground growth,
and is determined by the proportions of sand, silt, and clay present.
|
| Model No. | Method | Range & Sensitivity | Reagent System | # of Tests |
| ITK-1067 | Settling | Determines sand, silt, & clay
fraction, texture determined by chart | Dispersion, Floc. | 50 |
| R-ITK-1067 | Reagent refill kit | | | |
