We can calculate the actual concentration of calcium nitrate in the dilute solution by setting up a proportion: 6% Calcium Citrate delivers a source of calcium chelated with citric acid. Example: You wish to apply calcium nitrate at the rate of 500 lbs per acre. If you use calcium nitrate, apply 2 lbs. This works out to about 9 pound of N per acre. per 100 feet of row. For more informaction contact us at 503.559.6972 of fertilizer per 100 feet of row. Calcium is a vital nutrient for potatoes and most aspects of tuber quality can be improved by having a sufficient supply of calcium during growth.

The most common form of nitrate on the market for hydrogen sulfide control is liquid calcium nitrate solution. Typical pricing for calcium nitrate solutions is $2.00 to $2.50 per gallon. • Supplement with calcium nitrate at 100 ppm calcium (Note that calcium nitrate contains 19% Ca and 15.5% N). Side dressing applications involve spreading the fertilizer along the sides of the rows instead of applying the fertilizer directly around the plants. Practical curative dose rates for calcium nitrate vary anywhere from 1 to 2 gallons per pound H2S depending on the application. Nitrate Pricing and Sources. Mix the fertilizers thoroughly, 9.3kg of urea and 2.91kg of TSP, making 12.21kg.
