Arvalis is learning methods to incorporate camelina in rotations

Camelina is commonly used as a hedge, however may be valued as a money crop. A possible studied by Arvalis within the 4CE-MED challenge (2020-2023), via 3 ways of inserting this oilseed within the cultivation system.

the oil of camelina it’s recoverable for a number of factors of sale, however it’s in aviation biofuel that the prospects look most tasty. Due to its brief cycle, camelina can slot in a double reducing systemthat’s, with two crops harvested successively in the identical yr.

This particularity gives alternatives as a result of the laws distinguish biofuels based on the uncooked materials used and its manufacturing technique, privileging people who restrict the issues of competitors in using land for safe meals shops. Standard biofuels are made out of a feedstock that may compete with meals, whereas “superior” biofuels (together with “second era” ones) are made out of different feedstocks and processes (supply: Ministry of Ecological Transition and Cohesion Territorial).

Be opportunistic with camelina in the summertime pool

For a number of years now, many cooperatives and merchants have been testing camelina in summer time planting and early autumn harvesting, earlier than sowing winter cereals. Nonetheless, “sowing camelina in summer time by trapping behind winter barley (or different early harvested crop) is extra of a chance motion when the soil continues to be moist at harvest or when rains are forecast. Not working yearly, it’s troublesome to construct a sector with such a institution. Then again, it might be a good complement explains Sylvain Marsac, head of Arvalis’ bioresources-farm equipment-environmental companies division.

The institute is subsequently engaged on two different methods to introduce camelina into the cropping system, deliberate with producers, storage organizations and farmers:

  • sow camelina like winter harvestearlier than a really early sorghum or soybean, for instance
  • sow camelina like principal tradition behind a Cive.

These concepts are accompanied by questions and you could take a look at them. That is what Arvalis is doing via the European 4CE-MED challenge. This analysis challenge goals to develop diversified and sustainable agricultural techniques, integrating camelina.

Good belongings in mid-winter cultivation

In contrast with rapeseed, sowing camelina in autumn permits keep away from drought stress institution and pests. To maintain camelina in intermediate tradition, it’s mandatory to reap it in late Might to early June on the newest. The primary outcomes of the 4CE-MED appear to indicate that such a harvest date can be potential in a big a part of the metropolitan territory. As well as, pre-cutting is of nice curiosity for this cultivation sequence with a view to speed up plant desiccation.

The challenge will decide which principal crops can succeed behind camelina. This method has the benefit for customers of assembly sustainability standards for “superior” biofuel stamping. For OS, this harvest date on the finish of Might doesn’t require no dryingwhich is a crucial benefit.

An ideal place behind a Cive

The vital growth of anaerobic digestion in France led stakeholders to recommend planting camelina as the primary crop behind a Cive with sowing in mid-Might and harvesting in late August. Camelina is kind of drought tolerant and the financial danger is far decrease in comparison with maize or sunflower: seeds would solely price €50-60/ha, in comparison with €180 and €150/ha respectively for maize and sunflower . As well as, camelina requires little fertilizer (solely 60 kg N/ha based on the primary 4CE-MED outcomes).

Harvested in late August, camelina doesn’t require drying. Nonetheless, it could be much less properly paid than when positioned in a consortium, because it doesn’t enable assembly the factors for superior biofuels.

Crop system advantages but to be quantified

If Arvalis is on this oilseed, it’s due to its agronomic and environmental pursuits for rotation. Camelina would have allelopathic results, facilitating the weed administration within the cultivation system. Discount of weeds and inputs, soil carbon storage based on the cultivation sequence and the development of farm resilience are a number of the potential benefits related to the introduction of this species in Mediterranean farming techniques, that are notably focused by the 4CE-MED.
The challenge makes it potential to accumulate references on the administration of camelina in winter intercropping or principal cultivation. “It’s a must to sow very near the floor and be very cautious in regards to the persistence of the earlier weeding packages. Relying on the herbicides used within the earlier one, it’s a must to know find out how to abstain”, reveals Sylvain Marsac.
