With the introduction of John Deere Manure Sensing, producers and contractors now have an additional use case to benefit from the innovative HarvestLab™ sensor capabilities all year long. The HarvestLab sensor as the core hardware component can simply be moved from a slurry tanker to a forage harvester as the chopping season begins. Even during off season in the winter months the system can be leveraged for stationary use.
As the solution can be used all year long and across various use cases, the value generated consequently allows for a very quick amortization of the system.
The nutrient ingredients in liquid manure show high levels of variance not only between different manure types, between different storage pits or silos, between different tank loads, but also within each of those.
The following table shows an example of the level of nutrient variability that is occurring based on more than 4000 measurements per second of hog manure in one tank load.
|Ingredient||Average (kg/ton)||Standard deviation||High value||Low value||Range|
|Dry matter||8.79||2.33||15.40||1.00||2 - 9,6%|
|Ntotal||6.83||1.44||10.36||1.77||3 - 5,9|
|NH4N||3.69||0.76||6.71||1.13||1,8 - 4,5|
|P2O5||4.47||1.13||7.80||0.30||1,3 - 3,5|
|K2O||4.95||1.70||8.50||1.40||2 - 7,3|

Manure gets applied by its actual nutrient content and documented accordingly. With that, the system ensures best possible nutrient distribution and the economic value of organic fertilizer is put to optimal use. The system helps to adjust application rates to the actual field conditions and thus to increase productivity (e.g., increase yield) while minimizing input cost.
No matter how big the variability of nutrients is between tank loads/ponds, John Deere Manure Sensing enables a precise distribution and additionally it maximizes the crop yield potential. This means for the customer or contractor more savings on mineral fertilization based on precise manure documentation as well as easier and more accurate documentation (data access) for compliance.
Total cost savings in the range of 0,50 € - 1.66€ / m³ including labor time & machine cost, mineral fertilizer input cost saving plus increasing crop yields can be realized. Amortization time for the system can be realized within just 1 year or less depending on the amount of manure spread.

What drives also the growing importance of liquid manure application services for contractors:
Supported by the near-infrared sensor (NIR), John Deere Manure Sensing records all relevant manure nutrient levels such as nitrogen (N), ammonium-N (NH4), phosphate (P), potassium (K) and dry matter. Tests have shown that liquid manure has very strong fluctuations of nitrogen (N), phosphate (P) and potassium (K) between different loads (and even within loads) with a variance factor of 4-6 for nitrogen, a factor of 10 for dry matter and a factor of 25 for phosphate. This makes continuous measurement so important.
The ingredients are continuously measured during the application, more than 4000 times per second. That compensates for nutrient variations between different storage bins, differences between storage and transport as well as differences within individual tank. In addition the ingredient content is measured permanently directly before the application, not just while filling the tanker.
John Deere Manure Sensing enables significant improvements in accuracy of information and application of nutrients in liquid manure compared to taking one or a limited number of samples per storage container or transport vehicle. The known John Deere HarvestLab™ sensor (NIR sensor) and the respective calibration are developed to deliver a higher accuracy level compared to other available systems on the market today. The NIR sensor with manure calibrations has been benchmarked against both commonly used analysis methods in laboratories (wet chemical) and NIRS lab analysis. The results indicate that the relative error (and standard deviation) is in the range of wet chemical laboratory tests.
With John Deere Manure sensing ingredients can be applied based on a target rate for one nutrient and a limit rate for a second ingredient (i.e. target rate for N, limit rate for P).

John Deere 6R, 7R, and 8R Tractors with AutoPowr (IVT) or e23 transmission equipped with TIA can achieve the desired application rate faster and more precise than any rate control system (with flow-based regulation only) in a fully automated and comfortable manner. If due to hilly conditions and heavy engine load, for example, the tractor cannot reach the required speed, the fully integrated systems with partnering slurry tanker manufacturers like Fliegl Agrartechnik, Samson Agro, and Joskin can additionally allow the flow adjustment accordingly.
Compatibility for TIA:
The application rate control with automatic speed regulation through TIA plus flow control (with certified tankers) provides significant benefits compared to flow regulation only:
The John Deere Operations Center serves as the central location for contractors and farmers to connect to their machines and their fields. It connects contractors and producers through advanced partnership and data sharing functionalities. John Deere Operations Center is also the place where partners like agricultural consultants and machine specialists can offer their support remotely.
With John Deere Manure Sensing, the operator can determine which ingredients/values he wants to document with the GreenStar™ 3 (GS3) 2630 Display among nitrogen (N), ammonium-N (NH4), phosphate (P), potassium (K), dry matter (DM) and applied volume. The GS3 2630 Display supports up to four ingredients to be documented at the same time. As-applied maps can be uploaded manually or wirelessly with John Deere Wireless Data Transfer (WDT) into an Operations Center account. Contractors and producers can leverage the nutrient maps to calculate site-specific amounts of mineral fertilizer needed to achieve the optimum nutrient target levels.
This functionality ensures an accurate documentation for compliance purposes especially, thanks to the application reports. The application reports also give users the ability to charge for manure quality rather than quantity. This information can now be used to calculate reductions of mineral fertilizer applications.
The field analyzer additional lets the user see agronomic data and provides the ability to analyze the maps created during the application. Layers can be compared side by side to make better business decisions. Or, easily share data back and forth with trusted advisors of choice.
