Well I went to four relatively averaged out locations in my yard... two in the back, two in the front and make sure it was where the grass looked pretty 'normal' for my lawn - not super dead, not super green. I went to a depth of 4 to 5 inches with a trowel and got a nice zip lock baggie filled with the mixture of the 4 sample locations. The samples were submitted to AL Labs which has a main office about 5 minutes from my work. My lawn consists of about 75% hybrid bermuda and about 25% palisades zoysia, spread all over the place with the intention of it taking over my lawn sometime in the next couple of years (it has already started to spread quite a bit!). So my intentions are to promote the Zoysia - I could care less about the bermuda's needs since I want it to eventually go away. Results: (they gave me a chart that shows if I'm high or low - I'll list those results too - they go Very low/Low/Medium/Optimum/Very High) Soil pH: 7.1 (no target given) Buffer pH: 7.9 (no target given) Phosphorus: 116 LB/Acre (borderline between 'very high'/'optimum') Potassium: 244 LB/Acre (medium, almost optimum) Calcium: 2212 LB/Acre (on the low side of optimum) Magnesium: 338 LB/Acre (just slightly high side of optimum) Sulfur: 34 LB/Acre (middle of medium) Boron: 0.6 LB/Acre (middle of low) Copper: 3.2 LB/Acre (middle of medium) Iron: 530 LB/Acre (middle of very high) Manganese: 280 LB/Acre (very high side of medium, just short of optimum) Zinc: 5.8 LB/Acre (very high side of medium, just short of optimum) Sodium: 96 LB/Acre (borderline very low to low) Organic Matter: 1.7% ENR 78 (I have no idea what ENR is and it didn't give a 'target') Calculated Cation Exchange Capacity: 7.5 meq/100g (no target given) Calculated Cation Saturation (%): K-4.2, Ca-73.7, Mg-18.8, H-0.0, Na-2.8 (no targets given) K: Mg Ratio 0.22 (no target given) OK so here's my problem: While I recognize the name of some of these very well - I still have no idea over what period of time to 'compensate' for deficiencies, what to buy to compensate or should I just mix up a variety of things in dry or liquid form (I have a fertigation system or I can just apply dry pellets) and apply a bit at a time... or what. Furthermore some of these chemicals I haven't heard of since chemistry class and have NO idea why my lawn needs them, IF I can/should even try to find them and/or apply them, etc. And then some of the ratios and percentages... scratch that, ALL of the ratios and percentages, I have absolutely no clue what they mean. Help!
