Welcome to the OptiSurface Newsletter for October 2019.

It's been three months since our last newsletter. We've been busy supporting our clients, promoting through USA/Canada and releasing a new product.  
This is outlined in our News Of The Month(s) below.


We're excited to release our new machine control product, OptiWorks, which allows you to survey, design and carry out earthworks all from the tractor cab with the power and ease that OptiSurface is known for.

If you'd like to know more about
OptiWorks, please reply to this email or call me on +61 405-686-425 (Australia) or Preston on +1 870-340-2020 (USA).  

The Design Of The Month demonstrates the flexibility of OptiSurface for designing rice fields in Arkansas.

The Feature Of The Month shows how to use OptiSurface 1Way for furrow irrigation.

Midwest flooding delays planting. Minimize these by improving surface drainage with OptiSurface. As one Cornbelt client said: "The first field we OptiSurfaced was able to drain the incredible amount of rain and still have a nice looking crop." https://bit.ly/2RlkFyO

OptiSurface enabled this client in Arkansas to irrigate this field that wasn’t possible to irrigate with traditional land grading technology because he had a zero cut requirement in a part of the field.

The results show it is a matter of balancing the trade-off between earthworks cost and more efficient farming from higher uniformity of grades.

Feature Of The Month
Overview: OptiSurface 1Way is a Surface Type in OptiSurface which can drain to one direction (1Way). This suits crops grown with furrows where the water needs to drain in one direction along the furrow to exit the field. All furrows will have positive slope to one end. An example application is furrow irrigated corn where water is added at the top end of the furrowed row and must drain out the other end.

Example

An example application is a furrow irrigated field where water is fed using a polypipe from the top of the field and water can drain out to the lower end.

The field is currently grown with dryland corn and the client is looking for ways to improve the yield by irrigating. It will be designed with furrows running north-south and is located on the NW corner of the field.

Significant ponding was shown on the Drainage Analysis but these will be fixed with OptiSurface 1Way landforming design.

Proposed Topography

An OptiSurface 1Way Surface Type was used with main slope set between 0.086% to 0.172%. We have done some irrigation analysis that shows that varying the furrow slope by up to 200% doesn't significantly impact irrigation performance.

Additionally, the Max Cross Slope to Main Slope Ratio was set to 2 to reduce the risk of water over topping the furrows on areas where the cross slope is significantly higher than the main slope.
