Tropical Farms, which operates several large macadamia nut farms on Oahu, has adopted modern irrigation techniques such as drip irrigation and mechanized harvesting to maximize yields and efficiency. In the past, Hawaii's agriculture was mainly dominated by sugar cane and pineapple. These fields were supplied with water through an intricate system of ditches. On Oahu, the water was sourced from the northeast side of the island and delivered to Kunia sugar cane fields in the center or to Waialua on the north coast.
Additionally, artesian wells were drilled around farms to supplement the ditch systems. Similar ditch systems were also present on all of the major Hawaiian Islands.
Drip irrigation
is a popular method used on Oahu farmlands as it is an efficient way to deliver water directly to the roots of plants. This method is especially beneficial for macadamia nut farms as it helps conserve water and reduce labor costs. It also helps reduce soil erosion and runoff. Mechanized harvesting is another modern technique used on Oahu farmlands.This method involves using machines to harvest crops, which helps reduce labor costs and increase efficiency. It also helps reduce crop damage and improve yields. Overall, modern irrigation methods such as drip irrigation and mechanized harvesting are essential for maximizing yields and efficiency on Oahu farmlands. These methods help conserve water, reduce labor costs, and improve crop yields.
