How do you calculate granular fertilizer?
When using percentages in calculations, convert the number to its decimal form (for example, 26% = 0.26; 5% = 0.05). (1.0 lb nitrogen per 1000 sq ft) ÷ 0.26 = 3.8 lb of a 26-5-10 fertilizer is needed to supply 1.0 lb nitrogen per 1000 sq ft.
How do you calculate the amount of fertilizer needed?
Amount of fertiliser kg/ha = kg/ha nutrient ÷ % nutrient in fertiliser x 100. Example: You need 20 units (kg) /ha of phosphorus (P) and you plan to use single superphosphate with 8.8% P. You can reverse this calculation to work out how much of a nutrient you are applying.
How many bags of fertilizer do I need for a half acre?
Half Acre Space A half acre of land measures 21,780 square feet. Divide that by the 1,000 square feet you used to calculate your fertilizer needs, and you get 21.78.
How do you calculate nitrogen per acre?
Calculate the pounds of fertilizer per acre you must use to apply 50 pounds of nitrogen per acre (N/A). To do this, divide the amount of the nutrient wanted by the proportion of that nutrient in the fertilizer used.
How much is nitrogen per acre?
The $504 per ton price in 2016 results in a nitrogen fertilizer costs of $52.24 per acre. The costs savings for anhydrous ammonia then is $10.36 per acre. The $10 per acre in nitrogen savings can vary. Different sources of nitrogen will have different prices and thereby impact nitrogen savings from 2017 to 2018.
How many pounds is 28 gallons of nitrogen?
UAN28 weighs 10.6 pounds per gallon, so 10.6 pounds X 0.28 = 2.9 pounds.

What is the fertiliser calculator?
This Fertiliser Calculator compares the nutrient content of more than 1500 commercially-available fertilisers. A Dashboard tab is made visable when a DAFWA login is obtained. This tab allows development of more detailed and personalised fertiliser schedules.
What is the University of Georgia fertilizer calculator?
The University of Georgia Fertilizer Calculator was developed to assist users whose fertilizer needs require adjustment from the standard soil test recommendation due to a change in units, availability of fertilizer products, and/or a difference in land size.
How do I select the appropriate amount of fertiliser?
Select the appropriate Amount in kilograms (kg) or tonnes, (t) for solid or prilled fertiliser or litres (L) for liquid fertiliser. Press Calculate for the nutrient content of the fertiliser applied.
How do you calculate irrigation in table fertilizers?
For example, if your water contains 14mg/L, enter 14 into table. Estimate the irrigation used between normal fertiliser applications and enter the mm as L value and the rate (per) as hectares.
