Re-doing my front lawn #870293

Asked May 27, 2024, 3:24 PM EDT

I did a soil sample test last June and this was your institution recommended this in the first attached image. But I am going to till my yard up and would you still recommend this or should I use starter fertilizer? Attached as the 2nd attachment? Thank you Alan

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.

Thank you for your quick reply back. I didn't communicate with them about this. This area already has grass and this was the recommendations from just sending in the samples I sent. But I am going to level this area of my lawn. So I am going to kill this section of grass because of the uneven ground, so since doing this and going to reseed this whole section should I still use this recommendations then?

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.

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.

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.
