BIG N update for 2013 season

Peter Sullivan - Product Manager on 13/03/2013

As a business we have worked hard over the past 12 months to address the issues within our control in order to improve our ability to service you, the grower. This has included improvements to our linehaul fleet and storage facilities that improve our capacity to deliver across the entire BIGN footprint.

Focus on Calcium

Dr Rob Norton - IPNI on 05/03/2013

Calcium (Ca) is an essential plant nutrient required by animals and plants in relatively large amounts for healthy growth. In addition to its role as one of the macronutrients in plant nutrition, sufficient Ca has a role in maintaining soil physical properties, and in reclaiming sodic soils.

Soil Phosphorus Availability

Philip Hoult - Agronomy Solutions on 05/03/2013

Most plants take up the bulk of their phosphorus requirement early in their life, in the seedling stage of annuals and early regrowth of perennials. While phosphorus is not mobile in soils, it is one of the more mobile nutrients in plants.

Perfect Pulses

Lee Menhenett - Technical Agronomist on 05/03/2013

Pulses are gaining favour in many cropping rotations to provide a boost to soil nitrogen levels and give crops a disease break.

Seed bed utilisation

Jim Laycock - Technical Agronomist on 18/02/2013

The maximum application rate of fertiliser in the seed furrow is primarily influenced by the susceptibility of the crop species to ammonia and osmotic effects of the fertiliser, application equipment and soil conditions at planting and post planting.

Are you going to lose urea this season?

Lee Menhenett - Technical Agronomist on 12/02/2013

The loss of Nitrogen from Urea, through the process of volatilisation is high. Volatilisation is the process where gaseous ammonia is lost from urea as it attracts moisture on the soil surface. A number of factors contribute to this process. Volatilisation losses can be minimised by timing urea applications and by using a fertiliser with a urease inhibitor.

Soil Nitrogen reserves decline

Jim Laycock - Technical Agronomist on 07/02/2013

There seems to be a trend in falling soil nitrogen and organic carbon levels across the cropping regions of Victoria, New South Wales, Queensland and South Australia. This overview of soil reserves is based on soil tests conducted by Nutrient Advantage Laboratory Services.

Make soil testing the next stop

Phil Hoult - Agronomy Solutions on 31/01/2013

Growers are being encouraged to make soil testing their next priority, with the grain harvest now complete. And it seems advisers have heeded this advice with a large increase in soil samples being received at the Nutrient Advantage laboratory in Werribee.

A timely reminder about potassium

Jim Laycock - Technical Agronomist on 30/01/2013

Potassium (K) is a major plant nutrient required by plants in similar quantities as nitrogen, and in larger amounts than phosphorus.

Which test is best?

Rohan Davies - Technical Agronomist on 30/01/2013

Rohan Davies, Technical Agronomist with Incitec Pivot Fertilisers, discusses the differences between leaf tissue testing and petiole sap tissue testing in potatoes.

Field days look at fertiliser efficiency research

Incitec Pivot Fertilisers on 29/01/2013

What happens to fertiliser once it is applied in the paddock and how much of it is converted to pasture?

'Best Bet' fertiliser rates revealed

Charlie Walker - Technical & Development Manager on 13/12/2012

An in-depth analysis of a long-term fertiliser experiment at Dahlen, near Horsham, has revealed which nitrogen and phosphorus rates have performed best over the past 15 years.

Understanding and preventing zinc deficiency

Jim Laycock - Technical Agronomist on 13/12/2012

Seed furrow distribution is important when considering row spacing distribution and root interception of an immobile micronutrient such as zinc. If zinc is needed, sowing with a zinc fortified fertiliser is the preferred option, with placement with the seed the most effective method.

Accu-Spread Testing Shows Superphosphate Particle Size Impacts on Spreading Bout Width

Wes Wheelhouse - AFSA on 10/10/2012

Unfortunately many agronomists have observed the effects of uneven fertiliser application resulting in areas of poor crop / pasture growth where nutrients have been under applied and areas of very strong growth where fertiliser has been over applied in a regular pattern across a field.

Placement with pre planting nitrogen

Jim Laycock - Technical Agronomist on 09/10/2012

Some growers have been forced to replant significant areas of cotton because of fertiliser burn on the seedling roots, after applying either BIG N® or urea.

Soil Carbon - Black gold or just a lot of hot air?

Rohan Davies - Technical Agronomist on 07/09/2012

Soil carbon refers to the total carbon found in soil and it includes both inorganic and organic forms. The following discussion is focused on organic forms because, unlike inorganic forms, the organic amount can be strongly influenced by land management.

Green Urea to reduce ammonia loss in pastures

Helen Suter - The University of Melbourne on 06/09/2012

The breakdown of urea by a process known as hydrolysis leads to production of ammonia (NH3, a gas) or ammonium (NH4+), a plant nutrient. When urea is topdressed, any NH3 that is produced can be blown away from the site and this leads to poor use of applied nitrogen (N). One way of minimising the risk of NH3 loss is to apply a urease inhibitor with your urea.
