The new Dung Ordinance calls for a realignment.
There will be a re-enactment of the Dung Ordinance in 2015 and there is already a lot of discussion going on about it. What do the new specifications involve and what new assessment standards and statutory framework conditions do agriculturists have to expect? The AGRAVIS group is zeroing in on this question in detail to try to work out and present some solutions.

- Stefan Hanebrink, AGRAVIS-plant cultivation consultation
For instance, AGRAVIS Technik Service GmbH recently invited people to a round of talks that was dedicated entirely to fertilisation with liquid manure. The title was "Current tendencies and techniques of modern liquid manure spreading" at the Semmenstedt, Germany location. More than 120 agriculturists, work contractors and persons from the region who were just interested accepted the invitation. Experts in agricultural equipment industries, experts from the Chamber for Agriculture and the AGRAVIS group explained the latest trends, experimental findings, machine developments and ways to get support. One speaker was Stefan Hanebrink from AGRAVIS plant cultivation consultation.
Mr. Hanebrink, the new Dung Ordinance might hit the breeders hard. Why?
Hanebrink: We are expecting more intense regimentation when spreading nitrogen and phosphorous. That will force operations in tillage regions to utilise their liquid manure in a number of operations to keep the nutrient balances under control. There might also be new specifications for spreading techniques. Putting it all together, the idea is to use the nutrients in operations as efficiently as possible so they are most effective.
How can AGRAVIS help here?
Hanebrink: We're delving into various processes for spreading mineral fertiliser in plant cultivation. That includes strip till in combination with organic side dressing for cultivating maize over long periods. Of course, we want to conscientiously examine the strategies we recommend ahead of time to make sure they make sense and are suitable to practical application.
What are the benefits of the strip till process in combination with organic side dressing?
Hanebrink: The soil is cultivated in strips while applying the liquid manure or ferment residues to the soil at an approximate depth of 20 centimetres before seeding the maize. Then the corn kernel is laid into the cultivated strips about a week later. That means that this functions as side dressing. One benefit of the process is the fact that this automatically complies with the "four-hour rule" set by the Dung Ordinance. Beyond this, we have recorded lower ammonia and odour emissions while boosting the efficiency of the organic fertilisers used. Furthermore, this process has the benefit of maintaining the soil cultivation between the strips to a great extent while improving root and plant growth. Of course, we also have to say that strip till is not suited to all kinds of soils and cultures. Beyond this, it involves a high level of technical time and effort.
