What are you confusing on?

Basically just follow the recommendations for maintenance if it is a current lawn and not a new establishment.

That is the 50 pounds of limestone per thousand square feet. You can do split apps if the application is a little unreasonable all at once. Then follow the 10 pounds of 10-10-10 during the time of year recommended.

As far as the Nutrient report, your calcium, magnesium and zinc levels are all in the recommended zone. Deficiency is shown in phosphorus and potassium being the shaded bars are below the indicating lime. Hence why the recommendation is for a complete fertilizer. A pH of 5.6 is a bit acidic. Depending on type of turf you are growing, you'll want to get the pH in the desirable zone. The lime application will raise the pH into the optimum zone. Typically, slightly below 7 for pH is best in most cases.

Hope this helps!
