Description
Features:Multi function and high sensitivity probe sensor integration makes the tester more reliable and efficient in measuring data.The fertility and pH value can be tested by moving the key to fertility or pH.Without battery or power, simply insert the probe into the soil no more than 2.5cm, and then wait for a few minutes until the soil pH meter pointer stops swinging to obtain a stable reading on the dial. If the plant is very dry, the soil pointer of the soil pH meter will not swing, which means your plant needs water.Lightweight, portable, compact design, easy to carry, very suitable for indoor and outdoor use. Ideal soil testing tool for plants, gardens, lawns and farms.If there are any problems, please contact our store in time. We will give you a satisfactory solution.Instructions:How to analyze soil fertility/pH value1. First remove the topsoil about 5cm, then mash the soil down to 13cm depth. And remove all organic impurities in the soil that will affect the test results, such as leaves, roots, etc.2. Soak the soil with water to form mud. (rainwater or distilled water is preferred).3. Wipe the stick with a clean cotton or paper towel.4. Turn the function key to the first gear from the left/right.5. Insert the probe into the measured soil until the distance between the soil and the fuselage is no more than 2.5cm. After the pointer is stable, the data can be read.6. Record the data. Remove the probe from the soil and clean it thoroughly.The criteria for the analysis results are as followsLack (too little):Nitrogen less than 50 ppm, Phosphorus less than 4 ppm, Potassium less than 50 ppmIdeal range:Nitrogen 50-200 ppm, Phosphorus 4-14 ppm, Potassium 50-200 ppmExcessive (too much):Nitrogen More than 200 ppm, Phosphorus More than 14 ppm, Potassium More than 200 ppmIf the analysis results show that too little means: lack ofPlease use liquid fertilizer to supplement nutrients for different plants. (refer to the instructions on the fertilizer package for details)If the analysis results show that ideal means: idealAccording to the different plants you plant, use fertilizer once a month combined with irrigation.If the analysis results show that too much means: excessive1. Water a lot to dilute and leach excessive nutrients,2. For potted plants, they should be replanted to new soil,3. Do not apply any chemical fertilizer, but you can add manure, compost, plant residues, leaves and other organic substances into the soil.
