This one Bluetooth soil PH Meter can not only test soil, it could also test food, so as you can see, in the video, I have also test the cake, and gel for you. The cake is not very fresh, it has been at the refrigerator for 2 weeks, so it become the PH of 7.9, for reference, the suitable PH for Yellow layer cake should be 6.7—7.5, so you could see the yy-1033 could help us to check whether the food is good for us!
Most importantly, the PH is very important at plant growth, and this one is special for testing the soil. In the video, you could see the ph meter bring accurate measurement for the two plant pots. Most soil PH is among 5.5 ~6.5.
As you see, soil PH affect plant health a lot, if the PH is two low, then it could not take in the Nitrogen, phosphorous, potassium, sulphur, calicuim, magnesium, and molybdfenum, which will make the plant grow slowly, being small, and even withed, and rood rotten and death. And at too high PH, the soil cannot take in nitrogen, magnesium, iron, manganese, copper and zinc, which will make the plant have yellow leaves and inadequate nutrient and so on. So you see, the PH affect the plant growth a lot, and so do the temperature affect the plant to grow a lot also.
