The frost line—also known as frost depth or freezing depth—is most commonly the depth to which the groundwater in soil is expected to freeze. The frost depth depends on the climatic conditions of an area, the heat transfer properties of the soil and adjacent materials, and on nearby heat sources.
In order to have more successful yields, strawberry plants should be planted in well-drained soil, in an area exposed to plentiful available sunlight and air circulation. Presence of weeds may reduce air circulation for strawberry plants [10] and create a shaded, moist environment, [3] which would make the plants more wet and susceptible to ...
Drummer soil is the most abundant and extensive soil in Illinois. It occurs over more than 1,500,000 acres (6,100 km 2) in the state. It is the most productive soil in the state. Corn and soybeans are the principal crops grown in Drummer soil. The average annual precipitation in areas of Drummer soil ranges from 32 to 40 inches (1,000 mm).
The model assumes each 150 mm of a typical meter-deep soil holds about 25 mm of rain. Run-off from full soils (SDI=0) is soil capacity overflow (SCO). For the drying stage, both evaporation (E) from the soil and transpiration (T) through the plants are controlled by daily maximum temperature at five reducing rates (Keetch and Byram 1968; Mount ...
In 2012 the USDA updated their plant hardiness map based on 1976–2005 weather data, using a longer period of data to smooth out year-to-year weather fluctuations. [7] Two new zones (12 and 13) were added to better define and improve information sharing on tropical and semitropical plants, they also appear on the maps of Hawaii and Puerto Rico.
The Prairie Peninsula is an eastward projection of vegetation typically found in the American prairies into Wisconsin, Illinois, Indiana, and Ohio. [1] It is so named because it is an extension of grassland into the forests of the eastern United States. [2] Anthropogenic fire regimes are considered to have helped maintain the eastern prairies.

Fragaria vesca, commonly called the wild strawberry, woodland strawberry, Alpine strawberry, Carpathian strawberry or European strawberry, is a perennial herbaceous plant in the rose family that grows naturally throughout much of the Northern Hemisphere, and that produces edible fruits.
