When to Use OptRx<br />
Wheat<br />
The ideal application window for topdressing<br />
wheat is when the crop is between tillering and<br />
stem elongation growth stages. Any equipment<br />
capable of topdressing the crop will work.<br />
Barley<br />
The ideal application window for topdressing<br />
barley starts at stem elongation and continues<br />
to boot stage. Any equipment capable of<br />
topdressing barely will work.<br />
Rapeseed<br />
The ideal application window for rapeseed is<br />
from tillering till the flower is visible on the<br />
plant. Any equipment capable of topdressing<br />
rapeseed will work.<br />
The Causes and Effects of<br />
Nitrogen Variability<br />
Organic Material<br />
Organic material is one of the most<br />
significant sources of nitrogen in the soil.<br />
The more organic matter present, the more<br />
nitrogen the soil produces. Because organic<br />
matter can vary with different soil types,<br />
nitrogen availability in the soil can vary<br />
greatly across the field.<br />
Lodging and Under-Fertilizing<br />
Under-fertilizing crops can lead to significant<br />
losses in yield. At the same time, for wheat,<br />
barley and other grass crops, over-fertilizing<br />
can lead to lodging which can cost a grower<br />
up to 60 percent of total yield.<br />

OptRx Benefits:<br />
• Reduce application of nitrogen in nitrogen-rich areas.<br />
• Increase yield potential in nitrogen-poor areas of the field.<br />
• Record crop vigor variation data across the field.<br />
• Balance the affects of organic material variability across the field.<br />
• Improve yield potential for crops harmed by denitrification due to poor drainage.<br />
Rate Table<br />
OptRx crop sensors are ideal for applying fertilizers, pesticides,<br />
defoliants, growth regulators and other agrochemicals – on-the-go<br />
at the rates necessary for optimum performance. Based on your own<br />
experience or working with an agronomist or crop consultant, select a<br />
Vegetation Index range and assign the recommended rates based on the<br />
range chosen.<br />
