BACK PADDOCK SOILMATE COTTON PLANT TISSUE PRODUCTS AND SERVICES
If soil testing was skipped this year and your preplant N program was interrupted by a shortage of N fertiliser product, letting the plant tell you what N it’s seeing when its roots are firmly established is a helpful aid to making N decisions when used alongside crop vigour assessments.
Cotton nitrogen management using old ‘rules of thumb’ is a higher risk strategy when N fertiliser availability is uncertain.
Simple, local options to manage this risk based on measurement and best science are now available with Back Paddock SoilMate products and services and our local plant tissue service providers’ network.

| Plant part | What can it tell me to help manage N? | When is it most useful? |
|---|---|---|
| Leaf blade (minus petiole) | General crop nutrient status and N based on growth rate and plant N stored to date. | All growth stages based unique interpretation data that uses days after emergence to determine adequate nutrient ranges |
| Petiole (leaf stalk) | Is the soil N supply matching the crop growth rate recently? Fine-tuning the timing of post-plant N. Avoid excess plant vigour and quality defects at defoliation. | Squaring till 4 weeks post first flowers. Crop cut-out |
| How does it work for in-crop nutrition | Benefits |
|---|---|
| With Back Paddock cotton plant sample you only have 2 steps: 1. You collect samples 2. Lodge your samples to your local service provider o Crown Labs, Moree o Netecom, Griffith o Nutrilab, Goondiwindi Compare this with the extra work in completing lab forms, packaging/arranging freight, inputting data and creating reports. | Saves you time (hours with each sampling) |

| Plant Samples are dried locally to ensure against plant sap leakage which can occur in any long transit to lab analysis. Sample cooler boxes are available from each service provider | No sample degradation in transit to the lab |

The outcomes:
- Optimise yields and nitrogen costs
- Contribute to cotton industry’s environmental stewardship and emissions reduction goals – ‘measure’ and aim for Nitrogen Use Efficiency (NUE)
- “… five years to 2018-19, on average almost 60 per cent of the emissions to grow and ship to port a bale of cotton came from nitrogen fertiliser”
