Get better precision with grain tests

Grain nutrient testing is a quick and easy way to see what nutrients are leaving the farm with the grain. Incitec Pivot trials at the Darling Downs, western Downs and in northern New South Wales have looked at sorghum grain test results from the last three years of summer crops. […]

Dig deeper to know nutrient levels

Soil testing in the 0-10 cm zone has traditionally been used for phosphorus-based fertiliser recommendations. Deeper tests are often used to gauge nitrogen (N) availability, especially when mineral N has leached deeper after significant rain. But there are other nutrient and chemical constraints that can be better analysed by soil […]

2018 in review- Crop nutrition implications for 2019

In November 2018, plant nutrition consultant Rob Norton presented growers and advisors with yet another insightful review of the 2018 cropping season, and how it may impact crop nutrition in 2019. Rob’s webinar focussed on the more strategic nutrient management decisions. These are longer-term objectives (3-5 years), planned at the […]

How to assess new crop nutrition products

Every year, new fertilizers and other crop nutrition products come onto the market. Crop response to essential plant nutrients is well understood. What is less clear is the efficacy of other crop nutrition products. Do microbial amendments, acids, plant, and animal extracts, and other compounds also enhance nutrient use? Legislation […]

Crop nutrition discussions at the GRDC Updates

GRDC Communities is bringing “Ask an Expert” to the 2019 GRDC updates.   Crop nutrition implications after the drought Senior crop nutrition experts including Mike Bell (QAAFI), Sean Mason (Agronomy Solutions) Richard Daniel (NGA), Jim Laycock (Incitec Pivot), Maurie Street (GOA) will discuss the year ahead. Three “early risers” forums […]

What is the benefit of deeper phosphorus sampling?

Testing deep phosphorus (P) can improve fertiliser recommendations with a more accurate look at soil P stocks. It can help to know how much P is in the profile, and where it is. The topsoil is usually the most nutrient dense part of the soil. Maturing crops also rely on […]

What is the phosphorus buffering index?

The Phosphorus Buffering Index (PBI) approximates a soil’s ability to ‘fix’ phosphorus (P). Soils with a high PBI quickly and tightly bind fertiliser P making it unavailable to plants. Low PBI soils can’t lock-up much P, leaving most applied P for plant uptake. Use PBI to improve interpretation of critical […]

Top hits in 2018

Here are our five most popular articles and videos from 2018. GRDC Communities Crop Nutrition published 46 articles last year and these articles covered many different aspects of crop nutrition in the Australian grains industry. These articles were prepared with and reviewed by, members of our Community of Practice, Australia’s […]

Implications of 2018 drought and frosts for nutrient management in 2019?

2018 provided many challenges for grain growers, with mother nature dealing out drought and frost and everything in between across Australia’s grain growing regions.  In light of these seasonal conditions and with harvest 2018 nearly over for many, what plans should you be making for your 2019 crop nutrition program? […]

Can you come to a BFDC workshop this week?

The Better Fertiliser Decisions for Cropping (BFDC) program wants feedback. How have we done so far, and how can we improve? If you can make it, there are two sessions this week: Date: Thursday 29th November 2018 Time: 10:30 AM to 12:30 PM followed by lunch Venue: Auditorium, Longerenong College, […]

Which soil problem should you fix first? Ask ROSA

Western Australian growers with multiple soil constraints can check which one is costing them the most. The WA tool, Ranking Options for Soil Amelioration (ROSA), assesses which soil management options will give the biggest return on investment. WA croppers lose $4.3 billion each year from soil constraints. Most losses are […]
