Strategically managing water and nitrogen

Researchers are transforming existing knowledge about how apple trees take up and use nitrogen and water into a useful decision support tool that growers will be able to use to help manage nitrogen and irrigation in apple orchards for a desired crop outcome. To help apple growers manage their orchard’s irrigation and nitrogen inputs, we [...]

Calcium to combat post-harvest disorders

AgFirst’s Dean Rainham outlines some practical management strategies to obtain optimum calcium levels in apple trees because inadequate calcium can result in post-harvest disorders such as bitter pit and blotch. Calcium supports cell wall integrity and, without sufficient calcium, cells become leaky, more prone to disease and can collapse and die. The incidence of bitter [...]

Management of apple nutrition in poor soils

Notes and presentation from Tienie du Preez for the Future Orchards® walks Winter 2016 Precision management of apple nutrition in poor and variable soil – notes Precision management of apple nutrition in poor and variable soils – presentation Part 1 Part 2

Post-harvest nutrient management

  By Dean Rainham As we head toward the end of harvest, it’s time to think about your fertiliser plan to boost your trees’ nutrition reserves in preparation for next season. Post-harvest nutrition is a key event in the orchardist’s calendar. Once the fruit is off the tree it’s time to replenish the tree’s reserves [...]

Nitrogen management in red-blushed pears

By Ian Goodwin, Lexie McClymont, Eileen Perry, David Cornwall and Steve Green Research has commenced at the Horticulture Centre of Excellence on nitrogen management in red-blushed pears. To obtain optimal yield and fruit quality, nitrogen must be managed to meet the crop’s requirement based on the available nitrogen in the root zone and tree demand. Current nitrogen [...]

Precision fertigation to improve apple orchard productivity

By Nigel Swarts Over three years, Nigel Swarts and the team at the Tasmanian Institute of Agriculture (TIA) have investigated optimising apple orchard productivity through fertigation to get nitrogen applications just right to get the most benefit and avoid vigour and poor fruit quality. It is common practice in the apple industry to apply fertiliser [...]

Perfecting your orchard’s nutrient balance

By Dean Rainham Good orchard nutrition for intensively managed apple and pear orchards includes understanding the interaction between nutrients to ensure those applied are most effectively used for fruit production. Most growers know the importance of applying the right amounts of nutrients to ensure the tree is not lacking any of the essential macro or [...]

Understanding irrigation requirements

By Ross Wilson and Richard Pentreath More effective and efficient irrigation is required to achieve increasing yield and fruit quality expectations and make best use of limited water resources.   Optimal irrigation can be achieved by using a combination of soil moisture monitoring and basic water budgeting techniques. Optimal irrigation can be achieved by [...]
