Orange Trees Irrigation – How to irrigate citrus trees
The average orange tree responds greatly to water supply. Many researchers have reported that lemons and oranges generally increase by 50% faster, when the ground is wet than when it is dry. It is also reported that the growth of a fruit at temperatures above 100 °F (37 °C), was twice each day in wetter soils than what it was in dry soils. The flowering period (spring) is very critical as far as water supply is concerned. A water stress during the flowering period will have a dramatic decrease in production.
There are three rules of thumb when irrigating orange trees. The first says that we have to water the soil whenever it is dry, so as to keep it moist (but not soggy) at all times. The second says that young trees need more frequent irrigation than mature trees do. According to the third, trees in sandy soils may need as much as 3 times the quantity of water that orange trees in clay soils need. However, these are rules of thumb that give a general direction. Every orange farm is different, with a distinct soil identity and tree portfolio (number and age of trees). Orange farmers shall make a further research and seek advice from local agronomists in order to optimize the quantity of water supplied to the orange trees.
Irrigation may be performed by flooding with double circular basins, with grooves and sprinklers. According to the American Society for Horticultural Studies, water conservation efforts and frost protection measures have been major impetus to convert irrigation delivery systems from overhead sprinklers to microsprinklers over the last 30 years. Microsprinkler systems have the advantage of lower initial costs compared to solid set sprinkler systems for widely spaced tree crops. Low-volume microsprinkler systems provide a greater degree of freeze protection than both drip and conventional sprinklers. Moreover, applications of fertilizers and other chemicals can also be made more timely, uniformly and cost efficiently using microsprinklers.
