If the pH of your garden soil is not in the optimal range for the plants you are trying to grow you may end up having issues. Often plants grown in a soil that does not have the optimal pH dont produce or if they do their harvests are low while the plant may look stressed. On todays joint episode between the Testing Garden Assumptions and Urban Garden Series, I am going to take a look at soil pH, how to easily measure it and how you can adjust the pH over time if need be. pH is measured on a 14 point scale with 0 being the most acidic 7 neutral and 14 the most basic.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eThree Way Soil Meter With PH Detector \u003c\/strong\u003eis a Perfect tool to test the soil conditions (Moisture\/Light\/ PH) of fruits, flowers, vegetables, shrubs, etc. Its an Ideal and necessary tool for gardeners, vegetable and fruit growers, and all those who plant trees and grass.

It consists of a float that is attached to a switch, and as the float rises or falls with the level of the liquid, it activates or deactivates the switch. The CSSP sensor is characterized by the fact that it has a contact-type switch, which means that the switch is activated when the float comes into physical contact with a stationary part of the sensor. The sensor is typically used in applications where the liquid level needs to be monitored or controlled, such as in sump pumps, water tanks, and overflow protection systems. It is often preferred over other types of level sensors because it is simple, reliable, and inexpensive. The CSSP float sensor may be used with liquids that are compatible with the materials used in the sensor, and it may have a maximum operating temperature and pressure
