re: Need Hydroseeding info.

Depends on the test. You can get a kit and do it yourself but I'd get one that you send off to a lab. It will take a couple weeks probably.

LSUAg - Soil Test Kit Locations

You're looking mainly at your NPK values and ph level. Nitrogen-Phosphorus-Potassium The most common place you have probably seen this is on fertilizer bags. 13-13-13 or something else. Nitrogen helps with leaf development, phosphorus with root, and potassium I forget the lawn applications.

ph is your soil's acidity from 0 - 14 (most acidic - most alkaline). Being too far one way or the other will hamper the grass' ability to take in nutrients.

A soil test will also show your micronutrients like calcium, iron, etc.

When you get your results back there is usually a guide on what the levels mean and what you should do to amend your soil.
