Soil Testing Kit - Test PH Ammonia Nitrogen Phosphorus Potassium - PH Test Kits for Lawns Garden Grass Plants.

it is easy to use. And give results very quickly.

I really liked this test kit and the instructions were detailed BUT, one of the test solution bottles was EMPTY. It looks like it could have spilled out during shipping. I have tried to email the seller following their instructions to contact them directly, and have heard nothing back. UPDATE the seller read this review and found my email and sent me a complete NEW KIT free of charge. Very satisfied.

Easy to use even if outcome is disappointing but that's exactly what you want to know.

Test results all in a flat line reading. Have ran the samples several times. With low results from a garden that had outstanding growth.

First of all, this product contains 3 different sets of instructions, and they don't agree with each other. To test the soil, all 3 sets of instructions say to put 2mL of water from the main test tube into the smaller tube, along with 0.2mL of reagent. The smaller tubes only hold at most 0.5mL in total, so regardless of which set of instructions you follow, it's impossible to get the correct ratio of test solution to reagent. To make it even worse, the instructions say to put about 1 inch of soil with 10mL of water into the main tube. This is also impossible; the tube doesn't hold that much. It's is impossible to follow the instructions as written, which makes the results extremely questionable. I tried guessing at the correct amount of test solution and reagent based on the video included on the product page. I got no discernible reaction for any of the tests. Unless the seller significantly revises the instructions, this product is completely useless at best, and gives wildly inaccurate results at worst.
