COVER White mustard

Green manure, Ground water protection / Nitrogen conservation, Mulch sowing, Humus formation, Protection against erosion


  • Gelbsenf Cover, Sack vor Bestand
  • Gelbsenf Saatgut
  • Gelbsenf COVER, grüner Bestand
Classic white mustard with delayed flowering
  • Rapid and healthy initial development which allowes flexible sowing dates
  • Fast soil coverage with pronounced leaf formation for effective weed suppression and optimal soil tilth
  • Flowering delayed and strong vegetative development for optimal rooting and improvement of the soil structure
  • Freezing off safely - the frozen mulch layer protects against erosion during winter
  • Preserves nutrients during  winter, reduces the risk of leaching and provides the nutrients for the following crop in spring
  • COVER is especially recommended for cultivation in water protection areas and mulch sowing
  • Excellent suitable for agricultural blends

Use the chances of crop management

No matter whether catch crops are used for erosion protection, nutrient preservation, for fighting nematodes or as efficient weed or weed grass suppression, a soil well penetrated by roots and a completely covered soil surface are essential.

Check the N-management for legumes as well

The main topics of the new fertiliser ordinance are the tightening of the N-requirement calculations, the N-balance surplus and the blocking periods for fertilisation. What are the consequences for legumes? Can they be used in crop rotation for nitrogen fixation?

An interesting alternative to spring peas

The growing of frost tolerant field peas is becoming more attractive, as new varieties promise greater cultivation reliability.

When and how does tillage make sense?

Catch crop growers with long-term experience know when mechanical tillage of catch crops is required or, if necessary, how can it be avoided. Greening specifications and the newly added catch crop varieties, however, call for us to consider this topic once again.

Removing the plough: What change is there in nitrogen fertilisation?

How should nitrogen fertilisation take place when using conserving soil working techniques? A difficult question because arable land can look very different especially when a plough is not used. Dr. Konrad Steinert, LOP Landwirtschaft ohne Pflug (Agriculture without the Plough), explains the solutions.

Sustainable intensification and the new German Fertiliser Ordinance DüV: Do they fit together?

Can Germany meet the requirements for “sustainable intensification” and is a positive development slowed down or promoted by the new fertilisation ordinance? Prof. Friedhelm Taube, Christian-Albrechts-Universität Kiel, makes a critical appraisal.

“Only well-established crops lead to optimal N-fixation”

On the farm of Klemens, Markus and Agnes Schmeink catch crops have always been used in order to build up soil organic matter and to prevent erosion. The pilot project of the agricultural department of North-Rhine Westphalia for the water framework directive also puts a focus on efficient nitrogen usage.

Diverse crop rotation: What does it achieve and cost?

Crop rotation diversity is the most important agronomical answer for a wide range of current challenges – reaching from plant protection issues, extreme weather conditions to the amendment of current fertiliser regulations. Thus, are crop rotations with less lucrative plant varieties viable? How does it influence humus content and nutrient balance? Sven Böse evaluated different crop rotations.

Optimise nutrient availability = Improve fertilisation balance

The reformation of the fertilisation ordinance gives farmers the incentive to tackle soil fertility with greater intensity. Because only a healthy, well-structured soil can store nutrients optimally and make them available to the plants. This complex system can be influenced positively using catch crops. The most obvious measure for securing the nutrient supply is to provide the plants with regular and requirement-oriented organic and mineral fertilisation. As this possibility will be restricted in the future through the reformation of the fertilisation ordinance, additional arable measures will need to be incorporated.
