A forty pound (40) bag is the amount of 25 percent nitrogen fertilizer needed for a 970 square foot bed.
Specifically, calculate the amount of 25 percent nitrogen needed for a 1,000 square foot bed. Convert the 25 percent by multiplying it by 100 to get 4. Then divide 4 by 1,000 square feet to get 38.8 pounds.
I'm pretty sure 25 pounds of fertilizer should do it.
How much nitrogen per square metre have you put on the soil??
5 and a bit ;)
PF = ( 4.5 lb / 1000 sq ft ) ( 2500 sq ft ) = 11.25 lb fertilizer needed

3 pounds of fertilizer To solve: Think of 2 lbs per 600 sq. ft. as a ratio or fraction. Thus, 900 sq. ft. * (2 lbs / 600 sq. ft.) is equal to 3 lbs.
The fertilizer will cover a square plot 20 feet by 20 feet.
(7,125/3,325) x 7 = 15 sacks
It can be very disheartening to see your latest vegetables in your garden patch wither and not succeed to become prize winning vegetables as you once hoped for. It’s true that there could be a myriad of different reasons why they failed to flourish. One possible reason is the wrong fertilizer, so here are some pointers on how to choose the right chemical fertilizer: • Make sure your chosen product has the right proportions of chemicals, all plants need the following to flourish: nitrogen, phosphorous and potassium as well as other secondary and micro-nutrients. So whichever brand of fertilizer you choose make sure it has NPK written on it, it will usually be followed by numbers such as 24-6-6. This means the manure has 24 percent nitrogen, 6 percent phosphorous and 6 percent potassium. • As a rule it’s best to buy enough fertilizer to last you throughout the year. But it all depends on what you will use the fertilizer for. If it’s going to be used for your lawn then you could perhaps do a simple calculation of the lawn size in square feet and then multiply it by the application rate in pounds per square foot. This will give you an idea on how much fertilizer your will need. • Look carefully at the brands of fertilizer and find out how often you have to apply them to your plants or lawn. If you don’t have much time, to keep adding fertilizer to your chosen area then it’s best to choose something which only requires adding fertilizer once every 2 or 3 months. However, if you do have free time to pursue this activity you may want to look at brands where you must add the fertilizer once a month. Selecting the right fertilizer will definitely help your prized vegetables succeed in growth and development. If you are worried about chemicals, you may want to consider an organic fertilizer.
