Getting the Nitrogen rate right is critical to profitable farming. Richard Quinlan explains the various nitrogen pools and how to use information on all of these N pools to optimise Nitrogen application for the yield potential of the crop.

As the name suggests, trace elements are nutrients required in very small amounts by plants. Nick McKenna runs through some of the key trace elements and the best way to supply these to a crop or pasture.

Weed control is a big part of what agronomists focus on every day. Peter Newman gives and introduction to the major cropping weeds and an overview of their control

Are you going spraying or are you going killing weeds? Peter Newman explains the importance of boomspray set up to create the right spray quality for the product to ensure it hits the target.

We now know that summer weed control is critical to a successful crop. Peter Newman explains that summer weeds take moisture and nitrogen from the following crop and even a short delay in spraying has a big effect.

The first step in a successful crop is a knockdown and pre-emergent herbicide. Peter Newman shows us the common knockdown and pre-emergent herbicides, and how to mix and rotate between them to minimise the risk of resistance.

Herbicide resistance is a major threat to modern farming. Peter Newman explains the science behind herbicide resistance and the major resistance mechanisms.

Weed control was easy when all of the herbicides worked. Peter Newman shows us that weed control is more complex now with herbicide resistance, but we are having a win using a combination of tools.

Insect and Disease control is an important aspect of agronomy. Hilary Witwer gives and introduction to the common insects and diseases that we face.

The first step in crop disease management is correctly identifying the disease. Hilary Witwer shows us some of the common crop diseases and how to identify them.

Now that we have identified the disease we need to manage it. Hilary Witwer runs through some of the common fungicide strategies.

Insects are often tiny little things that can be hard to identify. Hilary Witwer shows us some of things to look for through your magnifying glass to correctly identify the little blighters.

We often have to spray insects, but now always. Hilary Witwer shows us some of the common insecticides along with explaining the thresholds that tell us when it is economical to spray.

Farmers know how to harvest their crop, but there's also a lot of things they can do to optimise harvest. Peter Newman runs through some of they key decisions made at harvest, how to measure losses to optimise efficiency, and some of the harvest weed seed control tools that growers have to choose from.

Agriculture is an exciting space, and there's a lot of new technology around the corner. Nick McKenna shows us some of what he believes will be very useful technology in the years to come.

Does every part of a farm require exactly the same nutrients? Probably not. Nick McKenna runs through the science behind using variable rate technology to vary the inputs across a farm to optimise profit.
