Bottom line: moist soil acts as an insulator, slowing heat loss across a grass plant’s root zone. It’s not just actively growing grasses that benefit from wet soil heat retention. Dormant ...
In late autumn and during winter, they retreat down from the top 5 cm of soil and burrow down between 50–200 mm into the soil. During this phase, the grubs undergo a colour change from grayish/white into a yellow/cream colour. Once they reach the appropriate depth, the grub empties its stomach and starts to form a smooth oval shaped cell.
However, the exact proportion of total water usage for agriculture varies widely between 'wet' and 'dry' years. In wet years, agriculture is responsible for closer to 30% of total water consumption and in dry years closer to 60%. [2] Water for agriculture is used to irrigate more than 9 million acres (36,000 square kilometres) of cropland annually.
The larvae, known as "chafer grubs" or "white grubs", hatch four to six weeks after being laid as eggs. They feed on plant roots, for instance potato roots. The grubs develop in the earth for three to four years, in colder climates even five years, and grow continually to a size of about 4–5 cm, before they pupate in early autumn and develop ...
The 2.5 to 5.7 cm adults, which are reddish-brown with smooth shiny wing-cases, emerge from the soil from June to early August. The males are smaller than the females and have more strongly serrated antennae. The adults do not feed. [2] They fly at night, seeking mates.

A wet meadow is a type of wetland with soils that are saturated for part or all of the growing season which prevents the growth of trees and brush. Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland. [1]
A vertisol is a Soil Order in the USDA soil taxonomy [1] and a Reference Soil Group in the World Reference Base for Soil Resources (WRB). [2] It is also defined in many other soil classification systems. In the Australian Soil Classification it is called vertosol. [3] The natural vegetation of vertisols is grassland, savanna, or grassy woodland ...
