During the 2020 growing season, Agricen Australia's sister company in the United States, Agricen, hired a film crew to document the experiences of growers from four different farm operations. The result is Last Stand, a movie that follows some of America's top farmers as they try to grow the highest yields possible in a season full of challenges.
Our recent webinar, "Building the Best Foundation for Horticultural Crops," is now available to watch online. The webinar discusses agronomic practices that can help enhance horticultural production systems.
During the webinar, you'll hear from our guest speaker, Dr. Doris Blaesing of RMCG. Dr. Blaesing is a tree physiology and orchard management expert who provides an overview of soil health, root development, nutrient availability and water availability in relation to orchard crop nutrition.
You'll also hear from Dr. Brian Cornelious of Agricen, who explains how Foundation LM can help improve the performance of horticultural crops, including both permanent crops and short-season crops.
In 2017, a Nutrien Ag Solutions customer near Shepparton, Victoria, first tried Basis XC on his starter fertiliser. Today, all of the starter fertiliser on his farm gets treated with Basis XC, a biocatalyst technology that can be applied onto granular fertilisers to enhance nutrient efficiency.
“Our farm has good background nutrition in the soil, so I decided to compare straight DAP at our usual rate of 85kg/ha to DAP treated with Basis XC at 80kg/ha," said the grower, who is a cropper and oaten hay producer.
By slightly reducing the rate of the Basis XC-treated fertiliser in that initial trial, he felt he could better and more easily compare the two applications dollar for dollar.
Early observations of the trial showed that plants had a bigger root system, with many more finer root hairs, where Basis XC was used on the starter fertiliser. Moreover, these observations were backed up by yield results.
In this Nutrien Ag Solutions wheat trial, MAP fertiliser was treated with Basis XC to test its ability to influence nutrient availability and uptake from the granular fertiliser application. Basis XC was applied on the MAP fertiliser at 2L/tonne. The treated MAP was then applied in the paddock at the same rate as untreated MAP (30kg/ha).
At harvest, treating MAP with Basis XC led to a wheat yield increase of +108kg/ha compared to untreated fertiliser.
Our latest webinar, "Maximising Nutrient Use Efficiency in Cropping & Pasture Systems of Australia," is now available to watch online.
During this on-demand webinar, you will learn:
- How fertiliser inputs break down and cycle in the soil after application, including the role played by soil microbiology
- How efficiently fertiliser inputs are taken up by the crop
- How two technologies - Basis XC and Foundation LM - can have a positive influence on fertiliser practices and maximise yield potential in agronomic programs
- Recent results with Basis XC in cropping and pasture trials
Applying Basis XC-treated single superphosphate (SSP) in dryland pasture considerably increased phosphorus and calcium uptake, a winter 2019 trial in the mid-southeast found, leading to improvements in feed quality.
Treated and untreated SSP was applied to dryland pasture, consisting of lucerne and annual grasses established on calcareous sands, prior to the break of the season (mid-April 2019). Tissue and feed quality tests were later taken on the 27th of August.
In this wheat trial conducted last season in Murray Bridge, SA, treating MAP starter fertiliser with Basis XC improved wheat yield and showed a positive return on investment for the grower, even under dry conditions.
Growing season rainfall was under 100 mm. The three treatments that were evaluated were:
- 65kg/ha MAP
- 75kg/ha MAP
- 65kg/ha MAP + Basis XC
Despite best practices, an estimated 40% to 50% of applied nitrogen is unavailable to the crop due to immobilisation by soil microorganisms or loss from the soil through denitrification or leaching. Although some soil microorganisms contribute to this nitrogen loss or immobilisation in the soil, others can enhance the availability or stability of nitrogen in the soil or even improve root growth and physiological functions, all of which can have a positive influence on nitrogen use efficiency.
In on-farm trials in grain sorghum, using a starter fertiliser consisting of liquid phosphorus and zinc with Foundation LM led to an average yield improvement of 653.50kg/ha (with an ROI of ~10:1) compared to no starter. The grower had previously trialled liquid starters—ones that did not include the Foundation LM biocatalyst—with no success.
The trials were conducted in G33 variety sorghum at three sites in Gurley, New South Wales. The soil was grey-black vertosol. Starter fertiliser with Foundation LM ("Liquid Boost Start") was applied at 7L/ha with water (80L/ha) and compared to water only (80-100L/ha). Yield data was collected by three S680 headers with GS3 and processed via Echelon.
Growers make a significant investment in their fertiliser every year. However, some fertilisers—particularly granular phosphorus and potassium (P and K) fertilisers—are not very efficient in the first season in which they are applied. Using a technology like Basis XC to increase nutrient availability and uptake can assist growers in addressing this problem and improving their fertiliser efficiency.
