Salutations Nina!
I'd like to elaborate a little more on Michael and Wayne's ideas about making your lawn a mow-able meadow, how no plants exist alone, and a brief history of lawns.
A mow-able meadow functions differently from a lawn in that you can create habitat for
local flora and fauna to thrive, and you can add elements that support your needs and pleasure- stacking functions. I'm quoting Paul Wheaton's 2014
Permaculture Keynote Presentation here; "for example, if you love the smell of
apple, you could grow
apple grass." Then, depending on whatever functions you would like the meadow to do, add certain species as needed. The rest of the video talks about 71 other amazing bricks of
permaculture. There is also a video on Paul Wheaton's Youtube channel about how to use a scythe if you are not the type of person who likes to use lawnmowers. Also, you
should check out Paul Wheaton's Advice on Lawn Care For the Cheap and Lazy in the link below; it has very concise and easy to use information for lawn care.

If there are any nutrient deficiencies in your soil, you may want to consider looking at this list of biodynamic accumulators by the Oregon Biodynamics Group. This way you can have the flora accumulate the necessary nutrients for you instead of using fertilizers.

The rest of their website has decent information about biodynamics; however, I do not see any significant scientific value in their discussion on cosmic influences in biodynamics. Nevertheless, it is an interesting resource.
This is just a little fun fact:
Lawns originated from the European aristocracy as a sign of wealth. The more fallow
land that was present, the richer a person was viewed in society in that time period because it meant that they did not have to grow their own food and could afford buying their food.
I hope some of this information was helpful to you.
