| Soil is composed of different particles; most of them originate from the degradation of rocks (mineral particles). Others come from plant or animal residues (organic particles). Soil can also contain living materials (bugs, roots etc.).The particles have small spaces between them called pores. When the pores are filled mostly with air, the soil is “dry”. When they are filled with water then the soil is “moist”.The NeuLog soil moisture sensor can be used to know when to irrigate becuase the plant does not have enough water. The sensor is called a tensiometer, which is used to measure the energy status (or potential) of soil water. The measurement is directly related to the ability of plants to extract water from the soil.In this activity we will monitor the moisture of soil in a pot containing a plant. Download experiment |
