What is MLSN?

MLSN, or Minimal Levels of Sustainable Nutrients, is a sustainable method of interpreting soil. By following the MLSN guidelines, we are able to accurately evaluate your soil and deliver the exact nutrients that your lawn needs to grow thick, green and healthy grass.

What Is MLSN?

Interpreting soil tests didn’t begin with MLSN, or even turf grass. Soil tests were first implemented to maximize agricultural production. This increased things like bushels of corn, but resulted in excess nutrient inputs and negative environmental impacts. Many lawn care companies encourage over application to maximize product sales. But the truth is, your lawn really doesn’t need excess fertilizer or an abundance of products. We believe that you just need the right nutrients to support your entire lawn ecosystem. And with the MLSN approach, we have the science to prove it.

Using MLSN to analyze turfgrass is a relatively new idea. Created by a group of independent scientists, MLSN has been proven by leading turfgrass experts from around the world as an effective approach to better understanding lawn nutrient management and ultimately, optimizing lawn and soil health.

Why We Use MLSN

At Sunday we believe less is more, working with nature is better than battling it with brute force and growing better means making lawn care easier. Over fertilizing your lawn leads to a weak ecosystem with “lazy” microbes that become dependent on chemical inputs. With a boost from precise and targeted nutrients, your lawn ecosystem will grow lush, green grass, build healthy soil, and crowd out weeds without becoming weak or dependent.

We are on a mission to make better lawn care as easy as possible. That’s why we created the Sunday Smart Lawn Plan. It uses MLSN and other leading plant science to remove all the guesswork and excess toxins from  lawn care. Then we deliver just what you need straight to your door.

Our approach is simple – just give your lawn ecosystem the right amount to support it’s (very efficient) natural processes. Extra isn’t better. Our nutrient application rates are generally less than half of what is normally recommended, because that is what your lawn actually needs. Over application generates runoff, causes environmental havoc, and creates extra work that makes everything harder than it needs to be.

The Benefits of MLSN

The benefits of MLSN boil down to using less product, spending less money and wasting fewer resources. With Sunday, consumers can be confident that they are getting exactly what they need with none of the excess that leads to a “lazy” lawn system. Minimum interference and application build a more resilient lawn. Our Smart Lawn Plans use light, frequent nutrient application rates to grow stronger, more resilient, and sustainable lawns with less.

How MSLN Can Work for You

With MLSN, improving your lawn ecosystem isn’t a guessing game, it’s science. Every Smart Lawn Plan starts with an easy-to-do soil test. Simply collect a small soil sample, send it back to us in the ready-to-ship container, and we’ll deliver the right nutrients to your door. Remember the MLSN analysis is only as good as the sample you take – make sure you follow the directions to take a composite sample at the proper depth. MLSN numbers are subject to interpretation, so it is important to have your soil analysis done correctly to know what’s really going on.

It is also important to assess, monitor and understand what your lawn looks like at its healthiest. If your lawn looks good, your soil is likely providing all of the nutrients your grass needs. If this is the case, the best thing you can do for your lawn is to support it by using the Sunday basic lawn care principles. But if there are signs of poor lawn health, or you are implementing a lawn plan for the first time, be sure to start with our soil test and follow MLSN guidelines. This will allow you to work with nature to grow a lawn that is better for people, pets and planet.
