It is calculated based on rainfall, air temperature, and other meteorological factors. [1] The KBDI is an estimate of the soil moisture deficit, which is the amount of water necessary to bring the soil moisture to its full capacity. A high soil moisture deficit means there is little water available for evaporation or plant transpiration. [2]
The highest temperature ever measured in Texas was 120 °F (48.9 °C), recorded on August 12, 1936 in Seymour, during the 1936 North American Heatwave, and again on June 28, 1994 in Monahans. The lowest temperature ever measured in Texas was −23 °F (−30.6 °C), recorded on February 8, 1933 in Seminole .
Jul. 15—A June heat wave caused agricultural conditions to decline around much of the state after steady improvements over the previous month, according to Texas A&M AgriLife Extension Service ...
The agriculture sector is sensitive to climate variability, [200] especially the inter-annual variability of precipitation, temperature patterns, and extreme weather events (droughts and floods). These climatic events are predicted to increase in the future and are expected to have significant consequences to the agriculture sector. [ 201 ]
In the United States, agriculture is the second largest emitter of greenhouse gases (GHG), behind the energy sector. [1] Direct GHG emissions from the agricultural sector account for 8.4% of total U.S. emissions, but the loss of soil organic carbon through soil erosion indirectly contributes to emissions as well. [2]
where is the mean annual temperature in Celsius. This was one of the first attempts at defining an aridity index, one that reflects the effects of the thermal regime and the amount and distribution of precipitation in determining the native vegetation possible in an area.
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.
In 2020, high temperatures and lack of rainfall led to a drought with D3 (extreme) and D4 (exceptional) categories in Texas as well as many other Western and Central states. The Western/Central Drought and Heatwave (event name) lasted through the months of June to December and resulted in 45 deaths as well as an estimated cost of 4.5 billion ...
