Whuts rong with my grass?

I really would like to have a nice, professional looking lawn. I have a problem with my grass and need help. Could anyone tell me what the problem is and what would you do to fix it?

Thanks,

Ray

 

Looks Like you let your dog on the lawn too much. (LOL)

 

Nope, not a dog.

 

Well. tell us kirby? looks to me like a fungus or a insect prob? unless the dawgs are not out ?.what is the soil look like?is the ph right ?what is the climate?

 

looks like rust or a magneesium "defiency"

 

Ok, On a more serious note. According to the Horticulture Gardener's Desk Reference you have a Magnesium or Copper deficiencie.

 

Soil test 3 months ago:

• pH 5.8
• P 63
• K 226
• Ca 955
• Mg 338
• CAE 14.6

Weather has been 40 days without rain (until 2 days ago), soil looks good and dark.

Was it possibly fed during august rainfall.
That wood would load it with nitrogen. Then
the drought and there the grass set with
a load of nitrogen and no moisture to process
and use it properly. just a possibility.

 

Was fertilized with starter 9 weeks ago and has been properly irrigated.
