High yields in row crops with reduced input and environmental impact

Farmers are currently faced with challenges which are not easy to reconcile at first glance.

On the one hand the costs for fertiliser have risen exponentially and resources are limited. Still, healthy plant growth is the basis for a successful yield and safe food production. At the same time, the protection of the environment has become a key topic of today’s agriculture.

Due to the risk of contaminated groundwater and local over-fertilisation with organic fertilisers, recent European regulations, rules and policies have defined new standards and reduced the kinds of components allowed.

Moreover, farmers are confronted with a decreasing acceptance for fertiliser and crop care products in society.



Fertilisation ensures the supply of nutrients to the crop, but over-fertilization often has undesirable effects on the environment and the ecosystem of the land.


How to keep the balance?

Conventional band application places a continuous band of fertiliser also between the plants, where the roots cannot reach it. This is the amount of fertiliser simply wasted and washed out.


With PUDAMA the amount and location of the fertiliser is precisely defined. The nutrients are only deposited where the roots of the grain can reach it and only as much as needed. Synchronised with the seed application at high speeds, a cloud of fertiliser is placed under each maize corn during maize seeding.

Every seed has an optimal fertiliser depot at its disposal which is completely absorbed by the plants. In this way, loss and leaching is avoided and the production of fertiliser raw materials can also be reduced.

In brief, PUDAMA is increasing the efficiency in the use of mineral starter fertiliser in maize – thus maintaining 100% yield whilst saving at least 25% starter fertiliser.

fertiliser depot

A fertiliser depot is produced and deposited analogous to the driving speed and seed distance in the furrow. The fertiliser is placed by an air stream 5cm below and side wards to the seed.

We care with utmost precision and efficiency

We believe that with intelligent and efficient farming systems we contribute to sustainable agriculture, serving the world’s growing population.

The Results

The PUDAMA system ensures the reduction of at least 25% of starter fertiliser compared with the continuous application of fertiliser - whilst maintaining 100% yield.

With technology such as the Kverneland Optima TFprofi SX PUDAMA precision drill, farmers can save a lot by reducing fertiliser, transport and work costs. For example, if a farmer with 300ha of maize uses 150kg/ha DAP 18-46 in the conventional way, he would save 37.5kg/ha of fertiliser with the PUDAMA system. This means a saving of 7,875€* for 300ha.

In Germany up to 81,000 tonnes of fertiliser could be saved annually in future with the PUDAMA system, which would mean that 16,200 tonnes less of pure nitrogen and phosphate would be used. This corresponds to a saving of 25 % of the starter fertiliser currently used annually at the same high yield level.

The PUDAMA system has been incorporated in the Optima TFprofi with SX high speed row, offering reliability by high expertise in precision drills and proven machinery – proven by independent results from Universities.

After the studies of the PUDAMA system carried out in Germany in 2022 with excellent test results, this spring a limited edition of PUDAMA has been spread out to farmers for demo test trials all over Europe. 

Being as close to the local farmers as possible will allow us to convince the public and establish international references to all sorts of soil conditions, cultivation methods and crop management
