Hi,
Thanks for your question. The soil testing laboratory tailors recommendations to the objectives indicated by the homeowner. If you communicated that you planned to grow grass in the area where you sampled soil, then I would follow the suggestion to fertilize the soil with a 33-0-0 mixture (1lb/1,000 sq ft nitrogen). The soil test indicates that no phosphate or lime are needed.
I hope that answers your question.
I would follow the recommendations of the soil testing laboratory.
If your soil doesn't need any phosphate, then I wouldn't add any (recommendation that I can see in the picture you uploaded recommends adding 0% phosphate). Surplus phosphate can end up in water runoff and potentially contribute to algae blooms in downstream bodies of water.
I would check to see if the nutrient mix included in the seed starter matches what your soil needs. If not, look for a 33-0-0 mix of fertilizer.
So I am having a difficult time finding 33-0-0 mixture of fertilizer even online I can't seem to find it anywhere do you have anywhere in mind that would carry this mixture? I live in the Duluth Minnesota obviously haha area if that would help you help me?
Much appreciated thank you
Thank you for answering my questions. And thank you for the quick responses from you yesterday this helps me a lotThank you,Alan
Hi,
In an online search I found nitrogen-only turf fertilizers that were 20-0-0 and 28-0-0 (also 46-0-0, but overdoing nitrogen could make the soil inhospitable to tender plants).
I suggest consulting with staff at a local garden center. They should be able to help you find a nitrogen-only fertilizer and let you know what application options are available (liquid, pellet/slow-release). Note that the best way to "fix" nitrogen in the soil is by incorporating plants that do this work, for example white clover.
Milorganite (an organic fertilizer made from biosolids) is an option for maintaining nitrogen in your lawn's soil. However, it does contain phosphorous, which your soil test shows you don't need to add.
Thank you for the information. I will look it all of this I thank you for the time to email a reply to me much appreciated thank you
Hi,
I was listening to the Smart Gardens show on WCCO-AM, and turf expert Jon Trappe of the University of Minnesota talked about applying nitrogen to lawns. First, a great way to continuously add nitrogen to turf during the growing season is to leave grass clippings in place (don't use a bagger when you mow). As the clippings break down they release a form of nitrogen that is readily available to plants. Clippings do not contribute to thatch.
Second, temperature limits when we can apply nitrogen fertilizer (always follow the instructions on the label). Depending on when you plant seed or lay down sod, you may need to wait until end of summer/early fall to apply a fertilizer. In the meantime, you can follow the best practice of leaving clippings in place as a way to add nitrogen to your new crop of grass.
Thanks for the info. Much appreciated thanks once again
