Precea precision air seeder

Smooth-running, rugged and reliable

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 fulfils the highest demands.

The benefits:

• Reduced soil throw ensures a very smooth running
• High service life thanks to the rugged and proven large-area seed drills
• Stepless working depth adjustment
• Exchangeable protection plate

FerTeC twin HD fertiliser coulter– with placement depth adjustment

The FerTeC twin HD fertiliser coulter provides even more operational convenience. 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 on 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

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 synchronised placement made a good impression during our field trial on light soils." ("profi" FertiSpot technical test · 08/2024)

• 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
• Available for fertiliser coulters with both leaf spring overload protection and coupled overload protection systems

The placement depth of the fertiliser is set mechanically on the implement, whilst the type and position of the
fertiliser dose are simply set using the software in the ISOBUS operating terminal.
