Variable General Info
Soil moisture ?Comment:To determine soil characteristics both at the soil surface and at the depths of nesting for bees, 17 ± 26 cm (Cane & Neff, 2011) soil cores were taken under the centre of each tent using a 2 cm in diameter and 30‐cm‐long soil probe when tents were removed. Soil temperature and moisture levels were measured at the soil surface and at 30 cm by inserting a digital thermometer (Cooper ATKINS®) and a soil moisture meter (EXTECH®) into the top and bottom of the soil core respectively. |
