Mareeba District, Queensland is one of sugarcane agricultural centers in Australia. In average, sugar cane growers in Mareeba owned a plantation spaces between 10 to 25 hectares. Mareeba’s local growers manage to get sugarcane yields in average of 180 to 200 tonnes per hectare with an average CCS of 10% to 12% and 12 to 14 months planting period. It is an interesting fact since Mareeba located in the northern part of Queensland’s that famous with limited water resources and low rainfall. Each year, in average, rainy season only lasts for 65 days.
With such natural conditions, water somehow is becoming very precious. Therefore, for water usage efficiency sugar cane growers in Mareeba, rely on Drip Irrigation technology. Along with drip irrigation other benefits in fertilizer savings, with 30% to 50% when compared with other irrigation methods.
Mareeba sugarcane growers utilize subsurface Drip Irrigation. According to numbers of growers, such application enable them to have a more controlled and more measured usage of water and fertilization. In return, subsurface drip irrigation supply precious nutrient fot the plants directly into the root zone and minimized evaporation. Such condition benefit the plants, the most. The similarity of nutritional intake produces uniformity of plants growth. In the end, the plants grow healthy and better.
When compared to the sugarcane crops yields in Indonesia with an average of 80 tons per hectare, of an average CCS of 8% and 10-month growing season, it is obvious to follow what Australia’s growers have had done. Although Indonesia is famous fertile soil and much sufficient water resources, it’s about time for us to try and utilize drip irrigation technology. With proper application and operation, drip irrigation technology is quite challenging to try in order to obtain much better results.
