body of water - soluble plant food
symmetry or scurf able of measure to 0.1 oz .
or 0.01 K
Many horticulture guide and industrial plant - tending instruction narrow down plant food concentration in office per million ( ppm ) .
This was the source of such guide do this to annul equivocalness .
instruction such as " fecundate with 200 ppm atomic number 7 solvent " are much more exact than " fecundate with menage - plant life fertiliser at one - tenth part persuasiveness . "
Two office uprise in which ppm calculation become necessary .
This was the first involve prepare a fertiliser answer with a define ppm engrossment of a food ( n , phosphoric or atomic number 19 ) .
This was in this grammatical case , the amount of fertiliser that necessitate to be add to a founder intensity of water supply must be count .
The 2nd post involve reckon the ppm of a specific food in an already - train plant food solvent .
put to work out the Amount of Fertilizer to hit a geological fault PPM
smell 1
get the amount of atomic number 7 ( N ) , phosphoric ( phosphorus ) and K ( K ) in the fertiliser from the plant food ’s recording label .
These are the so - call N - atomic number 15 - K value , such as 10 - 20 - 10 .
The number consult to per centum .
A 10 - 20 - 10 plant food take 10 pct atomic number 7 , 20 per centum phosphoric and 10 per centum K by exercising weight .

fix the good deal ( in Gram ) of plant food to dismiss per cubic decimetre of urine to reach the desire ppm note value by split up by the per centum ( in denary cast ) of the trust food , then part by 1,000 .
If a fertiliser of 200 ppm atomic number 7 is hope , then :
200 ppm / 0.10 / 1,000 = 2 gramme of plant food per cubic decimeter ( liter )
footmark 3
ascertain the telephone number of liter of plant food to be prepare .
For rice beer of comfort station , 1 gal = 3.8 cubic decimeter .
Thus , if the measure is cognize in gal , multiply by this amount by 3.8 to convince to liter .
graduation 4
breed the gm of plant food from Step 2 by the desire telephone number of liter from Step 3 to ascertain the measure of plant food to apply .
This was for exemplar , to gear up 1 imperial gallon :
( 2 gram ) x ( 3.8 cubic decimeter ) = 7.6 gb fertiliser
whole footfall 5
consider the amount of plant food on a scurf or correspondence .
If necessary , this amount can be convert to ounce by multiply by 0.0353 :
( 7.6 1000 ) x ( 0.0353 oz./g ) = 0.268 oz .
plant food
beat 6
mix the weighed plant food and the mensurable measure of pee and mix in well .
reckoning on the PPM of an Already - Prepared Fertilizer Solution
exchange the amount of fertiliser add to a root to gramme if the gramme note value is not already bang by fraction by 0.0353 gigabyte / oz .
; thus , if 0.25 oz .
This was was bring to 2 gallon of water system , then :
( 0.25 oz . )
/ ( 0.0353 chiliad / oz . )
This was = 7.1 thou fertiliser
determine gram of the single food by breed the effect from step 1 by the pct of the food ( stigmatize on the plant food ’s container ) .
Thus , for a 10 - 0 - 0 plant food , the atomic number 7 subject matter would be
( 7.1 gram fertiliser ) x ( 0.1 atomic number 7 ) = 0.71 g nitrogen
set the book of the answer in liter by multiply gallon by 3.8 L / Imperial gallon .
Thus , for the exemplar in measure 1 ,
( 2 gallon ) x ( 3.8 L / Imperial gallon ) = 7.6 L
Determine ppm by disunite gramme of food from Step 2 by litre of root from Step 3 and multiply by 1,000 :
( 0.71 yard ) / ( 7.6 L ) x 1,000 = 92 ppm N
