SSCM I guess is the more technical term, site specific crop management is what it stands for, and it basically is it’s about the [xx] right application it’s about instead of just managing a whole field with a simple the same blanket rate application, we’re actually taking that down to a smaller level so we can trace different areas of the field with different levels of nutrition or seed or emollient.

Evaluating Paddocks for Yield Variability

The usual steps that a farmer will go through to simplify is actually first establishing whether you’ve got the environment that would suit site specific crop management. Most farmers would be able to tell you where there’s a better part of their paddock or a worse part of their paddock. So once we’ve established that yeah okay, there is some variability that does exist, things like yield maps are often the first port-of-call, things like electromagnetic from activity surveys and DVR so just different layers of information that can identify where variation exists in a field and then taking the next step and going okay, what’s robbing that variation?

Usually soil tests or a tissue test are going to help us sort of work out A. What the constraints are, what meaning that there’s a lesser yield here or a higher yield there, and then they also are giving us an idea about the levels of nutrition that exist in the soil and from that we can then go and formulate a plan for what to do with the issue that exists in the poor areas, and that might be amelioration, so things like lime and gypsum come to mind.

Collecting Data on Nutrient Levels

And then we can also go down the path of vertebrate nutrition or save right application so if an area has a low level of phosphorus we can go and put more there and if an area has high level of phosphorus we can take out what we’re gonna put there and put it in the low area. And then obviously at the end of the season with the yield map we can come back and actually do assessments and just work out have we made some good decisions with the site-specific crop management. Collecting yield data is a fantastic place to start, most houses these days that growers are using have the ability to yield map.

Yield Data Essential for Future Planning

Not all of them are actually plugged into a GPS to ensure that happens, so absolute encouragement to growers to make sure that happens, collect that data, even if it sits in the computer for two or three years before you do anything with it, it’s just a great layer of information to go back and refer to thoroughly encourage farmers to get their yield mapping in as soon as they can, for the most important layer of information that exists out there is the bit that sits above the shoulders of the farmer, they’ve been over their paddock for the last thirty years or so.

Just having an understanding about what he’s driving that variation is very important with the local knowledge and what the father and the grandfather knew many many years ago. In regards to your taking on board site specific crop management program, well that can probably expect to get a better bang for their buck.

When it comes to the fertilizer they can not over fertilize in parts of their paddock and they can also not under fertilize in other parts of their paddocks. It’s just about getting the most out of their nutrition dollar.
