How can I get more from my Nitrogen?

Rohan Davies - Technical Agronomist on 13/12/2012

Technical Agronomist with Incitec Pivot Fertilisers, Rohan Davies, shares the findings from a recent nitrogen trial on the Atherton Tablelands in Queensland.

Nutrient sources for crops

Rohan Davies - Technical Agronomist on 18/04/2012

Plants can obtain the essential nutrients they require from a wide range of sources. When deciding which fertiliser is best suited to your crop, it is important to consider how effectively the plant can take up the nutrients.

Fine tuning water use in potato crops

Rohan Davies - Technical Agronomist on 28/03/2012

Rohan Davies, Technical Agronomist at Incitec Pivot Fertilisers, discusses how to fine tune water use to improve nutrient use efficiency in potato crops.

Measuring water infiltration

Rohan Davies - Technical Agronomist on 14/10/2011

Is the water you are applying going down or across the soil profile?

How does root development impact nutrient uptake in potatoes

Rohan Davies - Technical Agronomist on 05/09/2011

Potatoes require a steady supply of nutrients for optimum growth. Deficiencies or fluctuations of soluble nutrients, especially nitrogen, can cause poor plant growth, increase disease pressure and diminish yield and quality.

What can be done to reduce hollow heart in potatoes

Rohan Davies - Research and Product Development Manager on 04/07/2011

The key to reducing hollow heart in potatoes is to limit crop stress. This means maintaining consistent soil moisture, ensuring balanced nutrition for the crop and using quality seed at the appropriate spacing and timing.

How do fertilisers behave in the soil after application

Rohan Davies - Research and Product Development Manager on 04/07/2011

Some nutrients are very mobile in the soil, while some will not move far from where they are placed. Having an understanding of nutrient mobility will help you tailor your fertiliser program to ensure the crop has the best access to nutrients.

Thinking about climate change

Rohan Davies - Research and Product Development Manager on 04/07/2011

Vegetable growers may see many changes both directly and indirectly as a result of climate change.

Putting a value on chook poo

Rohan Davies - Research and Product Development Manager on 04/07/2011

Chicken manure can provide a very cost effective and reliable means of supplying vegetable crops with nutrients. However, research has shown that these nutrients can mineralise before they are taken up by the crop, which may lead to nutrient losses.

Do you test water quality

When growers apply irrigation water to their crops, they are also applying the nutrients contained in that water.

Evidenced based agriculture

When was the last time you asked your agricultural supplier to provide evidence that their products worked in crop as claimed?

Understanding New Fertiliser Technologies

Growers have more options than ever in new fertiliser technologies. However, it is critical for growers and advisers to understand the potential gains these technologies may provide and their limitations.
