Ok, so I got my results of the soil test back from UMass. Here are the results: -------------------------------------- Linestone and fertilizer recommendations for established turfgrass Apply 50 lb of calcitic limestone/1000 sq ft. Lime may be applied at any time, but mid-autumn or early spring is best Recommendation: 3 lb/1000 sq ft P205, and 4 lb/sq ft K20. To provide the above recommendations you may follow the directions below, or you may devise your own fertilizer program using the recommended amounts of phosphorus (P205) and potassium (K20) along with one pound of Nitrogen per 1000 sq feet. It may necessary to raise nutrient levels over several applications. Apply a 20-3-12 fertilizer @ 5 lbs/1000 sq ft in late April, late June, and very late August. If more convenient you may substitute the late April recommendation with the same application made 1 to 2 weeks after your last fall mowing. Follow these recommendations for two years. Retest the following year. Consult the interpretation sheet enclosed or obtain one of the turf guides referenced on the backside of the interpretation sheet. Micronutrient(ppm) Boron: 0.1 Manganese 1.3 Zinc 0.5 Copper 0.3 Iron 31.0 Sulfur 15.0 Soil Ph 6.1 Nitrogen: No3-N = 0 ppm BUffer pH: 6.7 Organic Matter 3.1% (desirable range 4 - 10%) nutrient levels (ppm) Phosphorus: 1 Potassium 45 Calcium 219 Magnesium 83 Cation exch Cap 4.0 meq/100g Percent base saturation K = 2.4, Mg = 13.9, Ca = 22.5 Micronutrient levels : all normal Extractable aluminum 128 ppm (soil range: 10 - 250 ppm) THe lead level in this soil is low. --------------------------- If I want to use organic fertilizer, do you have any recommendations for brands? Since I have missed the recommended late april application, can I apply one now, and still apply another in late June? If I apply the suggested lime amount, how will that affect the pH level? I am thinking of overseeding with kentucky bluegrass in the fall. Also i noticed in their interpretation sheet they mention that a Cation exch capacity of 10 to 15 is typical. and values below 6 may indicate the soil will have trouble supporting good turf growth unless special management techniques are employed. Should I be concerned? how can I increase this value?

WOW! Those are some big pictures. I get the point though. You have nutsedge - I would know for sure if I could see a seed head, though. Knock it out with sedgehammer. That stuff takes over fast doesn't it?

Can someone help me identify this weeds or grass and advise me on how to get rid of it. The weeds/grass has taken over my whole front yards. link to the pics: http://imgur.com/7nXj4EI,gBDuNIg,FRGIuAd,Hfy392J,Dh92KyC,Gnv9EWG,IbkN2ip,Cq11nv7#0 I live in an urban area in southern Louisiana if that help with identifying it. Thanks!

Those are not the same as the original question. Yours look a bit like Sheep Sorrel but we do not know your graphical location so it is hard to say what they are. You are likely to get more responses if you start your own post. It would also be useful to see the plant in situ.
