Potassium responses in beans, canola and wheat

Following the 2016 experiments investigating K responses, a series of field experiments was undertaken at Glenthompson in collaboration with Mr Jim Zwar and Southern Farming Systems. The experiments aim to compare the effect of timing and rate of potassium (KCl) on wheat, canola and beans. The sit

In-season Nutrient Management - South Australia

Take home messages • Good crops from 2016 along with heavy stubbles all suggest depleted N coming into sowing – so extra N may be advisable even with late sown crops. • The decision on N is really about meeting the yield potential that is set – late sown or poorly established crops may not warrant

In-season nutrient management 2017

Summary of the talk : N, S, B and maybe K may be deeper into the profile and access to these may be delayed or reduced. Set N supply to meet yield potential – make water and radiation the limiting factor – not nutrition Still a long way to go though so make N decisions in the light of that yield po

In-season nutrient management - 2017

What is a good nutrition program? A good nutrition program is part of a whole agronomy package and cannot – or should not – be considered in isolation from soil type, region, the way paddocks are prepared, the crop type and cultivar, crop protection, equipment available, the yield potential and othe

To replace or not to replace? - that is the question

Nutrient replacement is often discussed when considering rates after either good or poor seasons. Irrespective of off-takes, the general rule remains the same, the nutrient removed has to come from somewhere - from the fertilizer applied and/or from the soil reserves, and often both. So balancing

Potassium for fodder quality – 2016

Pasture responses to applied K in the dairy industry are reasonably common, but with the increase in the use of bought-in feed, many paddocks are at luxury levels, especially in close proximity to the dairy shed. N use on dairy pastures is common but there is less attention – in general – paid to p

Potassium responses on wheat and canola at Glenthompson, 2016

Potassium (K), along with nitrogen (N) and phosphorus (P), are the three essential nutrients required from soils by crops and pastures in large quantities. Typically, plant K demand is similar to N, although most of the K is present in stems and leaves rather than seeds. Table 1 shows typical N, P

Impacts of a wet season on crop nutrition

2016 was one of the wettest cropping seasons all across southern Australia, with flooding and transient waterlogging seen in many areas. As well, some areas also experienced late frosts which reduced crop yields where they hit. Despite this, the overall winter grain production in Australia is esti

Potassium removal and use in Australia

Since 2002, K use in Australia has remained essentially static at around 180 kt/y with a range between 130 kt (2008/09) to 215 kt (2015/16). Over the past two decades, the use of P has declined by around 10% while N use has increased by 50%, so that Australian growers are using relatively more N an

Nitrogen performance indicators for Australian grain farms

A survey was undertaken of 118 growers covering 474 fields over five years across south-eastern Australia. Crop type, grain and hay yield, residue management and fertilizer use were recorded and used to derive N partial nutrient balance (PNB) and N partial factor productivity (PFP). Estimates of t

Nutrient Use Efficiency beyond 2020

Summary Monitoring nutrient performance through a range of metrics or indicators is essential to assess changes over time. These metrics need to be described in terms of the system boundary, the time scale used and the sources of the raw data used. For broad scale nutrient use efficiency and effec

Research is world class and funding models most commonly include public and private partnerships, with industry support through compulsory levies on production providing growers with leverage over the strategic and tactical issues addressed.
