Hardiness zone. A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a ...
The climate of Ireland is mild, humid and changeable with abundant rainfall and a lack of temperature extremes. Ireland 's climate is defined as a temperate oceanic climate, or Cfb on the Köppen climate classification system, a classification it shares with most of northwest Europe. [ 1][ 2] The island receives generally warm summers and cool ...
The physical properties of soil, in order of decreasing importance for ecosystem services such as crop production, are texture, structure, bulk density, porosity, consistency, temperature, colour and resistivity. [ 1] Soil texture is determined by the relative proportion of the three kinds of soil mineral particles, called soil separates: sand ...
The thermal properties of soil are a component of soil physics that has found important uses in engineering, climatology and agriculture. These properties influence how energy is partitioned in the soil profile. While related to soil temperature, it is more accurately associated with the transfer of energy (mostly in the form of heat ...
The dew point, the temperature at which dew forms, was around 70-75 degrees in Central Texas, which translates into an "icky" heat. But the heat wave has also included a dry spell for much of the ...
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. For example, snow cover and asphalt ...
A minority of farmers in the Texas High Plains region are looking to organic and regenerative techniques to keep their soil healthy year round, despite a dry climate.
Late summer to early fall–when temperatures are around 70 to 75 degrees Fahrenheit—is the best time to plant new cool-season grasses, like Kentucky bluegrass, tall fescue, ryegrass, and fine ...
