Very easy to use, follow label rates. Great results.
It has been about two weeks since I applied the Humic Acid and Soil Loosener and I thought this would be a great time to summarize my application and results. I recently embarked on a lawn leveling project which was the first time ever attempting this type of improvement to our yard. My timing could have been better because our temperatures began climbing into the mid/high 80s. I was spreading approximately 5 cubic yards over 4000 sqft of KBG. Once I completed the leveling I decided to try the above applications on the front yard (1000 sq ft). I used the label recommended rate for both products using an Ortho hose end sprayer. The products flowed very smoothly through the sprayer and I was happy with distribution. My application went down approximately three days after leveling and watering in the sand. I followed the application with a good 1/2 “ of watering from my irrigation system. Nearly two weeks later temperatures have maintained in the high 70s, low 80s and my lawn has recovered amazingly. I really stressed it with the low cut/sand leveling during hot temps. We have nearly 1 year old sod on a new construction home. The top soil is good but its depth is very inconsistent and below the top soil that the build brought in, we have glacial till. I am hoping that with time the soil loosener and humic will penetrate deeper and allow the root systems to thrive farther into the soil. So far the grass has responded with aggressive new, healthy growth. My height of cut is now down to 1.5” and I plan on going to 1 inch this afternoon. My backyard is 3000 sqft and I did not treat it yet so I could compare results. The back yard is lagging behind the front in both new growth and thickness. My plan is to treat the back yard with the same application rates as I did in the front and document the progress with pictures. I will be applying the 15-0-15 fertilizer at the same time to both yards as well. I am extremely happy with the results that we have seen and how quickly the lawn bounced back. Great product that I would highly recommend to others!

Easy to apply and effective
The product was easy to apply and coverage was accurate to the 3,400 sqft label. I applied it to Bermuda (front) and Zoysia (back) lawn that I have. Both types of grass are very nitogen hungry turf. Applied about 3 weeks ago following aeration and topdressing to really "push" a topgreening and root development before the growing season is over for the year. No rain was in the forecast, so granular application was a "no-go", spray application was the best solution. The lawn had not had fertilizer in a while so following the application, the results were quick but limited most like due to fact that the lawn was starving. I could see this being most effective in a routine, monthly feeding to get the best results. Using it to "bring it back from the edge" like I did is not a fair assessment. The product is a broad spectrum of beneficial activities including humic acid and iron. Most granular fertilizers are N-P-K only and leave off/out supportive macro/micro nutrients and iron, this spray was very complete. The results I saw was a very quick green up and spreading of the stolons of both the Bermuda and Zoysia. This was especially evident with new growth coming through the topdressing. I would purchase this again, but will purchase it in a 1 gallon (or so) jug to refill the spray bottle to make monthly feedings more cost effective. Overall good product, balanced/complete feeding for your lawn. The bottle and quantity is especially good if you don't have a huge yard (where you can get at least 2 feedings/bottle. One thing to note. The bottle arrived in good condition, no leaks. However, after attaching to my garden hose, the bottle started leaking the concentrate... just be careful.

Effective but Expensive
I have used this product for several years and think it’s effective. Unfortunately I think the price is often too high so I bought it on Prime Day only because the price was more reasonable.

Best Product I've Found!! Wonderful!
I switched to a liquid fertilization system and I wanted something that would be safe for the pets and give me the results I needed. I contacted the company via Amazon with my soil test results and got a few recommendations, which for me was the Soil Loosener/Conditioner, Humic Fulvic Acid (Liquid Carbon), and Superior Nitrogen & Potash. I generally apply a bit less than recommended, but more frequently and I’ve never been happier with the results. I do add the Advanced 16-4-8 a few times a year, as well as organic insecticide. Other than mowing and mulching, those are the only products I’m using. I started with a mud pit of a yard 4 years ago when I bought the home and finally focused on the yard last summer by starting the overseeding and fertilizer process. The icing on the cake was the nutrients this year from Simple Lawn Solutions. I’ve had countless neighbors ask how I got such a green yard when most of the neighborhood was yellow dead grass. Having pets is also rough on the yard and even in the backyard where the “business” is done, you couldn’t even tell as the grass is green and just beautiful. I do find the liquid so much easier as you can clearly see where you’ve sprayed and what’s left. I use a tow-behind sprayer on my lawnmower and usually spray as I mow and then do a final round before calling it a day. It’s super simple, cost effective (way cheaper than hiring a service and much less expensive than many other products I’ve seen). I couldn’t recommend this enough and look forward to seeing what I can do next year as well!
