Reaping More From Macadamia Nut Farms

By Mia McCall


Today, macadamia nuts are recognized for their commercial value in various recipes all over the world. The crop is indigenous to Australia but was first commercialized in the Hawaii islands before its popularity as a cash crop picked. Macadamia nut farms were established in Australia only in the 1960s as the crop was being introduced across north America.

The yields obtained from a macadamia orchard are highly dependent on the average temperature experienced in the respective zones of cultivation. Blossoming will be initiated only if the night temperatures get to fall below 19 degrees Celsius. Frost ridden regions are inappropriate for macadamia cultivation since the low temperatures kill off young trees and developing blossoms on older trees.

This hardwood tree is hardy enough to outdo competition from many indigenous deciduous tree species. As long as the orchard is endowed with fine textured soil with good drainage, a rooting system sufficient to support the tree in the drought season can be established. Orchards established in direct wind currents should be surrounded with windbreak trees to block destructive windstorms.

The size of mature trees may give the farmer a hard time during maintenance activities. Digging your holes in a grid across the garden at 30 meters spacing should deal with these problems as your crop continues to establish for maximum productivity. If you cannot bring in a state appointed officer to conduct a soil sample analysis, infiltration rates can be estimated by filling up a hole drilled to the hardpan with water to observe how long it holds.

Also to be considered is the presence of stones and the topography because of their impact on the harvesting machinery. While initially identifying the orchard site, it may be necessary to consult landscaping experts. A layman may choose a site that has negative impacts on rights of immediate neighbors or is inaccessible by farm machinery.

Row placement should be tuned to the north south direction for better sunning of the trees at all stages. Choose the variety you intent to grow with care as it may determine the quality and cost of your produce. Consult widely with neighbors and state agriculture officers but you should learn to differentiate facts and unsubstantiated beliefs.

It may happen that the targeted buyer only accepts nuts of a certain variety. For those who may wish to produce mixed varieties the different species should be laid out during planting so that cross pollination is encouraged during the production period. A farm with mixed varieties may have to sort out nuts before marketing.

While windbreak trees may be a good inclusion in macadamia nut farms, the farmers must weigh the pros and cons of planting them on their property. They have the capacity to compete with the main crop for nutrients and sunshine. Planting the wrong species may also result in alternative habitats for rodents that are a nuisance to the farmer. Moreover, windbreaks are only necessary during the initial four years, after which removing them may come with a range of demerits especially if they are grown within the orchard.
