| Previous | 74 / 89 | Next |
- Pre-made reagents for ease of use
- All reagents marked with expiration date and lot number for traceability
- Manual titration performed with electronic pH meter
Details
The HI38074 is a titration-based chemical test kit that determines the boron concentration in irrigation water within a 0 to 5 mg/L (ppm) range. The HI38074 is supplied with all of the necessary reagents and equipment to perform the analysis, including the HI98103 Checker pH meter. The HI98103 Checker pH meter is used for sample preparation and for the determination of the pH titration endpoint. The HI38074 contains enough reagents for perform 100 tests.

Significance of Use
Boron is one of the micronutrients essential for plant growth. It may be present naturally in water, or it may find its way into a watercourse through industrial waste effluents. Boron in excess of 2.0 mg/L in irrigation water can be detrimental to plant growth, and some plants may even be adversely affected by concentrations lower than 1.0 mg/L.
The United States Department of Agriculture (USDA) reports the following classification:
|
Boron (ppm) |
Effect on crops |
|
< 0.5 |
good (except for very sensitive crops) |
|
0.5 to 2.0 |
some risks (many crops must be excluded) |
|
> 2.0 |
dangerous (may only be used for very tolerant crops) |
