Organic N-P-K help

[cleancutlawncare5382]

I have been studying organic fertilizers, preparing myself to offer the service to customers. I plan to use my own lawn and one other customer as the test sites / before and after pictures too.

I had a soil test done by the Agricultural lab from the state and here are the findings.

Recommend applying 3 times a year during growing season ( May, Sept, Nov) one of the following:
20-27-5 5 lb / 1000 sqft
18-25-6 5.5 / 1000
18-24-12 5.5 /1000
17-23-6 5.75 / 1000
16-21-4 6.25 / 1000
16-12-4 6.25 / 1000
11-25-11 9 / 1000
10-23-10 10 / 1000

PH level 6.5 none recommended

It looks like they would like to see Phosphorus ( middle# ) higher.

What would you guys recommend to address this organically?

What turf are you going to apply these to? Different grass has different requirments. For example, Centipede lawns should have no more than 9#'s nitrogen per 1,000 sq. ft. per year and ZERO phosperous and potassium. Its ideal pH is 5.3. St. Augustine, likes a 16-4-8 3 times a year. Its ideal pH is 7.1. Ammendments with micronutrients can be just as important as the macronutrients N-P-K.

So I was on Natures Lawn web site and looking at the fertilizers they offer. The 6-14-6 ( flower & Fruit ) has the highest level of phosperous.

Has anyone ever used this on lawn to raise phosperous ??
