FertiBioSol Project - Manure by MSV Normandy
As part of a previous call for projects (PEI, 2017 call for projects), three partner organizations (BioPousses, Sileban, and CFPPA Coutances) organized around the SOCLE Innovation AB project to experiment with and disseminate innovative techniques adapted to market gardening and vegetable farms in Normandy. The objective was to provide technical and economic benchmarks on techniques for soil fertility management based on biological methods and to address the hardship mainly related to manual weeding tasks in market gardening. The FertiBioSol project continues SOCLE Innovation AB's work on biological soil fertility management by proposing a broader scale of work at the farm level and adopting a prophylactic approach to pest management.
Manure production
Definition :
Composed of various organic matter wastes, derived from slurry (a mixture of animal excrement + urine) combined with absorbent and structuring bedding mainly carbon-based such as cereal straw, ferns, wood pellets, etc. It can be spread and incorporated, fresh or composted. The carbon element composition of the manure as well as its composting level will influence its composition.
Source of straw :
- Equine manure +/- strawy.
- Cattle manure +/- strawy.
- Goat manure.
- Sheep manure.
- Poultry manure.
Manure characteristics
Humus formation for 10 t dry manure :
DM manure = 10 t X K1 = 40% = Humus = 4 t
Manures used on the Desert vegetable farm :
| Sample | Horse manure | Poultry manure | |
|---|---|---|---|
| Agronomic value
characterization |
DM % raw | 59.8 | 77.8 |
| OM % dry | 64.8 | 74 | |
| pH water | 8.6 | - | |
| General
composition |
Organic N g/kg dry | 28 | 39 |
| C / N total | 11.5 | 9.6 | |
| Total N g/kg dry | 28.1 | 39 | |
| Major
elements |
Phosphorus g/kg dry | 12.6 | 33 |
| Potassium g/kg dry | 17.1 | 41.8 | |
| Magnesium g/kg dry | 5.9 | - | |
| Calcium g/kg dry | 28, | - | |
| Isohumic coefficient K1 (%) | 30 to 50 | 5 to 10 | |
Supply in market gardening
Producers :
| Producers | The NF U 44-051 standard for organic amendments usable in ORGANIC guarantees threshold efficiency values as well as product safety (composition, pollutant content, ...) | Purchase cost |
|---|---|---|
|
Donation or €20-30 per ton of delivered, spread cattle manure |
Use
Logistics :
Simple spreading or in ridges, with or without incorporation :
- Manure spreader.
- Straw blower (if very strawy manure).
- In ridges : Tractor + trailer.
