Question: I Have a bag of fertilizer with the Nitrogen on the bag is 15. (3, 500 Sq.ft Lawn). 1% / .15 = 6.7 (rounded), 3, 500 / 1, 000 = 3.5 6.7 x 3.5 = 23.45 lbs of Nitrogen needed for a 3, 500 sq. ft lawn correct?

When it comes to fertilizing established shrubs & instructions say use 1 cup for every 3 feet (linear) how broad of a strip of fertilizer should I use? So, if I am doing a 3-foot ling section around base of shrub how wide should my 3-foot line be? Thank you

hey,
i want to know how much time does it take to coat urea with polymer? and what equipments are used ? and overall budget ( roughly ) for the entire process from laboratory to release of the product. im a graduate student and im currently working on a project related to polymer coated urea. can you help me with that? thank you

Sorry, it is pretty obvious if you need 1 lb of N and your fertilizer is 25% N that you would need 4 lbs. The question is how many pounds do we need if we know our N in PPM?

I have one math question here. I have 6 three gallon pots filled with dirt. So 18 gallons of soil. I want to add my blood meal 20-0-0 but I have no idea how to calculate this. I'm horrible at math

[tomsensale]

so I would only need 12 lbs of milorganite? I figured if it's such low N I would need more? I would need 33lbs of 22-0-0

I want to ask you about amount of fertilizer to put on plants.
So Im working on this social project to teach local farmers about introducing a new type of fertilizer for them. I want to be able to teach them the basics of amount of N P K inside a fertile soil thats best for plants, specifically tomatoes, chillies, and other vegetables. For them to also cut their cost on fertilizers. I already know how to calculate the amount from your video but I havent been able to find the right amount of Nitrogen that is best for veggies. I read from you that is 1 lbs per 1000 sq feet for lawn. But I cant find the appropriate amount for veggies. Can you help?
Thank you

And this 11.35 lbs of nitrogen spread over 2, 500 sq ft. of coverage is only for one application. So for example Kentucky Bluegrass needs about 4 pounds of nitrogen for the entire year because of our shorter growing season here in Michigan, AND you can't put down more than 1 pound nitrogen per 1, 000 sq. ft. at a time, or you'll burn it. Therefore, I and others who adhere to this strict policy of not wanting to burn the grass will make this application four times a year during the growing season: early spring, late spring, summer, and fall. Too bad we can't find 100% straight nitrogen although I knew someone who applied straight nitrogen on his lawn. It was so green, it looked almost black...well, just extremely dark green...I was impressed. I guess that would be 100-0-0.
