Stregthening the management of your profitability

Concentrate on what's important

For your fertilisation tasks, ECONOV technology

  • Gives you peace of mind by automating all risky operations..
  • Provides fertiliser savings
  • Guarantees even distribution across the whole plot
  • Eliminates under- and over-applied areas


ECONOV works

  • On widths from 18 to 50 metres
  • Up to 4000

ECONOV, the only technology which manages the actual shape of the spreading ... curved

Every fertiliser distribution area spread using centrifugal fertilising is in a curve and not in a straight line.

SULKY is the only manufacturer in the world to manage this curved shape from its ISOBUS (QUARTZ 800) and non-ISOBUS (Matrix 840 GS) terminals.

1- Without Econov, numbers of under- and over- applications appear;
this spreading map also shows that by choosing a test plot with a distinct shape, Sulky used real operating conditions.

2 – With Econov, under- and over- applied areas are virtually eliminated.

Does Sulky technology save on fertiliser?



Yes for Emmanuel Piron, whose team carried out the study for Irstea: “Overall, there was a 9% reduction in fertiliser input in favour of Econov, that is to say 1380 kg, compared with 1515 kg in manual mode with DPAE activated. And above all, over- and under-applied areas are virtually eliminated in Econov mode.”

With ECONOV, all section opening and closing combinations are possible

In ISOBUS, ECONOV manages 12 equal sections regardless of the working width .

1. Starting rriving at a straight headland, the sections close gradually from the outside to the inside, following the actual shape of the spreading area… in a CURVE!

2. If the spreading width is reduced, during the last run for example, the sections close automatically according to the width still to be spread

Right and left modulation doubles the accuracy of your modulation

Unique on the market, right and left modulation doubles the accuracy of your fertiliser input.

modulation-gauche-droiteThis feature takes you further in your approach to precision agriculture. It makes it possible to reach your profitability objectives more easily.

The Sulky fertiliser spreader modulates the fertiliser application spread automatically right and left from your recommendation map.

This technology makes it possible to:

  • Reduce areas of over- and under-application of fertiliser
  • Reduce intra-plot divergences
  • Optimise yields throughout plots.

Econov, 100% ISOBUS also works with a Non-ISOBUS tractor

Practical for use on several tractors:

  • In ISOBUS, ECONOV is displayed on the SULKY QUARTZ 800 Terminal














In non-ISOBUS, ECONOV is displayed on the Vision console and the MATRIX 840 GS guidance bar
