Iowa's all-time hottest temperature of 118 °F (48 °C) was recorded at Keokuk on July 20, ... The NRCS divides Iowa into 23 soil regions. In general, soils of ...
The Natural Resources Conservation Service divides Iowa into 23 soil regions. In general, soils of southern, eastern, and western Iowa are loess-derived, while soils of northern and central Iowa are till-derived. Most level areas of Iowa have soils highly suitable for agriculture, making Iowa one of the most productive farming regions of the world.
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 rest of Iowa now ranges from Zone 4b, with a temperature threshold of minus 25 degrees, to Zone 6a in the extreme southeast and southwest, with a minus 10 degree threshold. The addition of 6a ...
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 ...
The soil suborders within an order are differentiated on the basis of soil properties and horizons which depend on soil moisture and temperature. Forty-seven suborders are recognized in the United States. [6] The soil great group category is a subdivision of a suborder in which the kind and sequence of soil horizons distinguish one soil from ...
Higher temperatures are also likely to reduce livestock productivity, because heat stress disrupts the animals' metabolism. Seventy years from now, Iowa is likely to have 10 to 20 more days per year with temperatures above 95°F than it has today. More severe droughts or floods would also hurt crop yields".
