Potassium and sulfur –how much is enough?

Grain producers have become more proficient at managing N in response to seasonal conditions, matching the right source with the right rate and applying the N at the right time and in the right place. In general P management is taken care of with at-sowing SSP, MAP, DAP or TSP, and after sowing the

Nitrogen mid-season

In many parts of southern Australia, winter rains have been kind and crop yield potentials are good to very good. Every year – good or bad – yield potentials and the on-going crop N demand should be reviewed to build a strategy to use the water available. With a starting point of 40 kg N per tonne

A check-up using nutrient deficiency symptoms

When the uptake of any of the essential nutrients is inadequate, the plant metabolism becomes disrupted and distinctive symptoms often begin to appear. Since nutrients are involved in specific growth processes, deficiency symptoms provide clues to what nutrient might be lacking. However, most nutr

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

Chelmsford P and K response 2014-2015

Research in Central Queensland has shown long term responses to deep placed P and K in cropping system. In 2014 a site was selected at Chelmsford (40 km north of Kingaroy, Queensland) to assess the response to deep placed P and K on these soils. The soil type is a vertosol and Table 1 below shows

Suspected Magnesium deficiency seen in 2015

Magnesium deficiency is not common in Australia, although on sandy acid soils it can be seen. The best diagnosis is using soil tests, deficiency symptoms and plant tissue tests. Treatment can be using dolomitic limestone or other magnesium containing fertilizers. Matt Nihill, Agronomist at Landma

Preparing for 2016 - reading the effects of the past seasons

Growers across the southern region are encouraged to make every effort to take accurate soil tests to guide nutrient input levels this year following the dry conditions of 2015. Well-below-average growing-season rainfall saw substantial areas of crops across the region – particularly in Victoria’s

High rainfall zone nutrient omission trials 2015

During 2015 four sites were selected - two in Victoria and two in South Australia, to investigate the potential limitation that nutrition may have on achieving wehat and canola yield potentials in that region. The sites were located at Inverleigh (canola), Glenthompson (wheat), Frances (canola) and

P for 2016

GRDC Meida Release Southern Region Grain growers in the southern cropping region whose crop yields were limited by this year’s dry conditions could be in a position to reduce input costs next season. Growers are advised to test their soils ahead of sowing in 2016 to determine whether an opportunity

K responses on the Southern Tablelands

In order to provide additional K response data to the Better Fertilizer Decisions for Crops database, a field experiment was established at Breadlebane in the Southern Highlands of New South Wales. A similar experiment was located in the same paddock in 2014. This region is located between Canberr

Presentations at Fertcare NUE workshops

Gaining confidence in the information we provide Two presentations were made at the Fertcare Nitrogen Use Efficiency workshops across the eastern states. Both relate to gaining confidence - firstly in the information we seek to share, and secondly with the process from soil test to nutrient recomme

Nutrient Use Efficiency on Grain Farms

Water use efficiency is widely recognised as a key performance indicator for crop production. Similarly NUTIRENT USE EFFICIENCY (NUE) for nitrogen, phosphorus, potassium and sulphur can indicate resource use effectiveness and economic performance of these important crop input. Why measure NUE? Fer

Response to deep placed P, K and S in central Queensland

Two field experiments were established in central Queensland at Capella and Gindie to investigate the immediate and then residual benefit of deep placed (20 cm) nutrients in this opportunity cropping system. The field sites had factorial combinations of P (40 kg P/ha), K (200 kg K/ha) and S (40 kg

K response in wheat

A new experiment was initiated at Chelmsford (near Kingroy) in 2014. This experiment again banded P and K compared to an unfertilized control, and compared 4 rates of K (O, 25, 50 and 100) where 40 kg P/ha applied. It also compared the response of 100 kg K/ha where P was present or absent. There

Soil sampling for 2016

Soil testing is the first step in identifying the RIGHT nutrient/s required, the RIGHT place for them and assists with determining the RIGHT rate to apply. The greatest potential for error in soil testing is in taking the soil sample. A 0. 5 kg sample collected and sent to the laboratory may repre


Regional Profile

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.
