Rain follows the plow. By this wonderful provision, which is only man’s mastery over nature, the clouds are dispensing copious rains [the plow] is the instrument which separates civilization from savagery; and converts a desert into a farm or garden. To be more concise, Rain follows the plow.
Little or no precipitation is one of the major causes of a drought. El Niño events affecting several parts of the world are often associated with hotter and drier weather conditions.
What is a drought and what causes it?
Because drought is defined as a deficit in water supply, it can be caused by a number of factors. The most important one though relates to the amount of water vapor in the atmosphere as this is what creates precipitation. More rain, sleet, hail, and snow can occur where there are moist, low-pressure air systems.
2004 tsunami in Indonesia: affected up to 5 million people2010 earthquake in Haiti: affected 3 million people. Current drought/famine/war in the Horn of Africa: affect 8 million people in 2018.
What is drought, its types, causes and effects?
What is Drought, its types, causes and effects. TYPES OF DROUGHT. Agricultural drought : this is type of drought in which the moisture level in the atmosphere minimizes which in turn affects the soil moisture. CAUSES OF DROUGHT. Low rainfall : the main reason for drought is low or lack of rainfall.
When does a drought begin and end?
The beginning of a drought is difficult to determine. Several weeks, months, or even years might pass before people know that a drought is occurring. The end of a drought can occur as gradually as it began. The first evidence of drought is usually seen in records of rainfall. Within a short period of time, the.
Is it better to plow when it’s wet or dry?
It is usually better to plow when too dry than when too wet. However, a light, mellow soil or a coarse sandy soil may be improved by plowing when wet, because the compacting effect of the moldboard makes it less loose and porous.
In the case of late fall or winter plowing the freezing of the wet soil causes it to break up into a mellow, friable condition. If plowing cannot be done early, cultivation of the unplowed land with a disc harrow will prevent drying out to a marked degree.
Why do farmers plow the same depth every year?
It is advisable to vary the depth of plowing, and even to subsoil heavy land, in order to break up the furrow-sole, but it is often just as important to plow sandy land the same depth year after year in order to produce a more impervious condition, which will prevent too rapid percolation, leaching and loss of soil moisture.
What should you do in a drought?
Water manually in fall and winter only if needed. Use mulch around trees and plants to retain moisture in the soil. Mulch also helps control weeds that compete with plants for water. Invest in a weather-based irrigation controller —or a smart controller.
How to prepare for a drought?
Position sprinklers so water lands on the lawn and shrubs and not on paved areas. Repair sprinklers that spray a fine mist. Check sprinkler systems and timing devices regularly to be sure they operate properly. Raise the lawn mower blade to at least three inches or to its highest level. A few extra items to take a look at: plant drought-resistant lawn seed, or don’t over-fertilize your lawn.
