Precea-TCC trailed precision air seeder

The FerTeC twin HD double disc fertiliser coulter with application depth adjustment
The high-performance double disc coulter ensures clean, reliable placement. The double disc coulter runs smoothly and deposits the fertiliser in front of the PreTeC sowing unit. The double disc coulter is completely maintenance-free and meets the highest demands, particularly for ease of operation. Initially, the relationship between the placement depth of the fertiliser and the placement depth of the seed is set just the once. The fertiliser coulter is automatically adjusted for depth if the sowing depth is subsequently changed.

The benefits: 

• Automatic placement depth of the fertiliser provides more comfort. 
• More exact depth placement on heavy ground. 
• Short set-up times, since the coulter pressure on the fertiliser coulter is also applied to the sowing coulter.

How FertiSpot works

1. From the metering system, fertiliser continuously enters the top of the dosing chamber.
2. The fast-rotating portioning rotor is driven by its own motor matched to the speed of the singling unit. The fertiliser granules in the portioning chamber are collected and amalgamated during one revolution of the portioning rotor. A consolidated fertiliser portion is produced.
3. The fertiliser dose is placed precisely into the soil via the outlet of the dosing chamber via the conveying section, synchronised to the application of the seed.

Spot-specific, under-root fertilisation

The FertiSpot for the Precea takes under-root fertilisation to a new level of precision and efficiency.*

With FertiSpot, the under-root fertiliser is deposited as a concentrated nutrient supply under the seed - exactly in the plant's future root zone. The young roots make optimum use of the fertiliser, since the fertiliser remains available for a longer period even under dry conditions. Inefficient fertilisation resulting from the leaching of the fertiliser in between the plants is prevented. This increases nutrient efficiency in comparison with fertiliser applied in a band.

Optimum early development of the plants with FertiSpot under-root fertilisation ensures good yields, especially during dry summers. The same level of yield from normal band fertiliser application is achieved - but by using up to 25% less fertiliser. Reducing the amount of fertiliser, whilst maintaining the same yield, increases profitability and improves working conditions in areas with higher nutrient requirements.

The FertiSpot system - practical results

• Reduced fertiliser input - same early crop development and the same yield by the concentrated and precise nutrient placement
• Reduction in non-productive time due to fewer fill breaks and longer operating periods due to the lower application rate per hectare
• Protecting the environment by reducing the amount of fertiliser used
• Maintaining yields, especially during dry periods

The same placement depth across all soil types

A even plant population of a crop without gaps allows the uniform development of all individual plants by optimising the supply of light, water, carbon dioxide and nutrients. The basis for this is the uniform placement depth of the seed at the correct depth - even in heterogeneous soils with varying firmness or consolidation. No problem when using the SmartForce option for the Precea-TCC - the yield potential of the crop can be maximised.

"Thanks to SmartForce, we have a uniform placement depth and therefore a better field emergence."

FertiSpot can also be used to apply under-root fertiliser in classic band application, if desired

Simultaneous maintenance of a consistent placement depth and optimum embedment of the seeds ensures high field emergence and provides the basis for good a yield.

Maintaining a consistent placement depth on varying soils or conditions where there is uneven reconsolidation represents a particular challenge for both the machine and the operator.

AMAZONE offers the SmartForce automatic coulter pressure regulation system as an add-on to the hydraulic coulter pressure adjustment.

The particular feature with this system is that the driver does not need to stipulate the coulter pressure, but rather they set the desired contact force on the terminal. This contact force is checked by measuring pins when in the field. If a deviation from the predefined contact force on the PreTeC mulch sowing unit is registered due to changing ground conditions, the SmartForce hydraulic system readjusts the coulter pressure accordingly. The correct contact force is precisely applied.

In this way, the coulter pressure is adapted to the differing ground conditions whilst on the move - uniform placement depths are thus reliably maintained under all ground conditions. This makes it easier for the driver and results in a more even field emergence.
 

The benefits:

• Uniform placement depth - regardless of any changes in soil conditions across the field
• Uniform plant population enables maximum yield potential by optimising the supply of light, water, carbon dioxide and nutrients to the individual plant
