Plant Growth Nutrients and Bacteria in Water Tests fertilizer concentration influence on plant growth and bacteria growth response.
Plant Growth Nutrients and Bacteria in Water Tests fertilizer concentration influence on plant growth and bacteria growth response. Monitor nutrient uptake and release due to plant growth. Chemical testing only takes a few minutes per sample. The bacteria sample grows for 2 days before reading.
# 566 Plant Growth Nutrients Plus Bacteria in Water
Each water sample is tested for this Set of parameters: Phosphate, Nitrate, Nitrite, Alkalinity, pH Plus Bacterial Growth (6 tests per set).
Dissolved Phosphate test scale
# 140 Dissolved Phosphate in Water
Colorimetric test strips. (1 test per strip)
Testing for Dissolved Phosphate in water is common, but
usually found in low concentrations. Because of low
concentrations, phosphate is involved with regulating bilogical growth and productivity in natural waters.
The color chart for this test allows you to read Dissolved
Phosphate in micrograms/L or ppb.
The Color Comparator Chart for this test allows you to read Phosphate levels in water at:
~0, 200, 400, 600, 1000, 2500 microgms/L or ppb.
(Note: concentration units are micrograms per Liter or parts per billion).
Results are obtained from this test in about 1 minute.
Nitrate and Nitrite test scales
# 135 Nitrate and Nitrite in Water
Colorimetric test strips. (2 tests per strip)
Nitrate / Nitrite test strips are for testing water in many applications from drinking water to water used to wash produce.
Nitrates and nitrites occur normally in nature from the breakdown of ammonia in the nitrogen life cycle. Nitrates in nature cause plant and algae growth that may affect the balance of water-based ecosystems.
Nitrate is found in fertilizers and animal waste. Rain tends to wash fertilizers containing nitrates into nearby natural water systems and ground water. Groundwater used as drinking water that contains nitrogen represents a hazard to babies. Many die every year as a result from “Blue Baby Syndrome.”
The Color Comparator Chart for this test reports concentrations compatible with EPA limits of total nitrogen and nitrite nitrogen in water.
The test reports levels of:
NO3 (as N): 0, 0.5, 2.0, 5, 10, 20, 50 mg/L or ppm;
NO2 (as N): 0.15, 0.3, 1, 1.5, 3, 10 mg/L or ppm.
Results are obtained from this test in 1 minute.
Total Alkalinity and pH test scales
# 115 pH and TOTAL ALKALINITY of Water
Colorimetric test strips. (2 tests per strip)
pH and Total Alkalinity are two of the most fundamental parameters in drinking water testing as well as a great variety of other applications of water usage. Alkalinity indicates the buffering capacity of natural waters. A water is buffered if the pH does not change greatly by addition of acids or bases.
The most effective buffering action is within the pH range of water from 6.0 to about 8.5. The productivities of water can be correlated with ph, alkalinity and the buffering system.
The color charts for these tests read pH levels and Total Alkalinity in mg/L or ppm.
The Color Comparator Chart test reports levels of:
pH levels of 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 11
Total Alkalinity 0, 40, 80, 120, 180, 240, 720 mg/L or ppm.
Both tests are on the same test strip.
Results are obtained from this test in 25 seconds.
Bacteria Growth Check test scale
# 180 Bacteria Growth Check
Colorimetric test strips. (1 test per strip)
Bacteria Growth Check is a test strip that has been specially formulated with Brain Heart Infusion media that allows maximum cultivation of fastidious aerobic bacteria found in some waters. This test could be used in a variety of applications, however it is not specific for any particular type of bacteria.
You can dip these strips in water or swab surfaces with them. The Bacteria test procedure then requires you to return the test strip into a clear plastic bag for incubation. After 48 hours of room temperature incubation, any fastidious bacteria on the test pad will multiply and turn the test pad pink to red. The darker and more consistent the test pad, the more bacteria that are present.
Bacteria Growth Check tests only a small water sample and requires a significant quantity of bacteria to show a change on the test pad.
