2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
The technology is based on use of livestock manure from dairy cows (excreta and cereals straw) for fertilisation of arable fields with 3-5 year rotation. Manure has a very good effect on soil production capacity and on growth of vegetable crops.
2.2 Detailed description of the Technology
Description:
1. The technology is applied in the flatlands of Ljubljana with an average altitude of 350 m.a.s.l. Average annual precipitation is 1400 mm. The area is characterized with often stormy precipitation events and occasional droughts. Silty loam soils in the area are moderately deep to deep with medium soil organic matter. Area has good availability of surface water and groundwater of good drinking quality. The biodiversity of the area is medium without any salinity and flooding problems. Sedentary agriculture with mixed or commercial agriculture is practiced with less than 10% of income coming from off-farm activities. The examined farm household has an average wealth and is fully mechanized/motorized. All farm households have a good access to services and infrastructure. The examinded farm is medium in scale with land patly owned by the land user and partly leased from other private owners.
2. Main characteristic is the use of livestock manure on arable fields and especially for vegetable production. Manure is composed from solid dairy cows excreta and cereals straw (wheat, barley) which is used as bedding for cows. Manure is composted for few months (4-6, depends on storage capacity). It is spread before ploughing and then ploughed into the soil. Spreading of manure is done in autumn or in spring. Knowledge on time of spreading and on handling with machines is needed.
3. Main function is increasing organic matter in the soil and also all major nutrients (nitrogen, phosphorus, potassium, magnesium, calcium etc.). This leads to better (1) productivity due to nutrients slow release, (2) better water holding capacity and (3) decreased soil compaction threat.
4. Major inputs needed to establish are: livestock (animals), stable adapted to the manure collection, use of straw bedding, storage facility (if possible covered with roof), manure spreader, and loading equipment. Major inputs to maintain are: keeping of the livestock herd and maintenance of the machines.
5. The benefits are: (1) increase in soil organic matter, (2) increase soil water holding capacity, (3) to maintain soil productivity, (4) increase in yields quantity and quality.
6. Land users like: (1) lower cost for mineral fertilisers, (2) impact on soil fertility, (3) it's a traditional method.
Land users dislike: (1) time-consuming - labour hours invested, (2) storage capacity takes space, (3) costs of transport.

fodder quality
product diversity
Comments/ specify:
Organic manure is crucial in vegetable production. The examinded farm would already have stopped the livestock production but then he would lack manure as crucial component for the vegetable production. Few years ago the land user only produced raw milk but as market demand for vegetable increased he started with this type of production.

No
6.7 Strengths/ advantages/ opportunities of the Technology
Strengths/ advantages/ opportunities in the land user’s view |
---|
Strengths: Mitigates drought. Use of mineral fertilisers is decreased. If fields are fertilised with organic livestock manure, the impact of spring drought on plant growth is minimal. |
Opportunities: Livestock manure is a basic fertiliser for vegetable production. Customers are asking farmer what he is using for fertilisation. They trust more to the product if it is fertilised with organic manure produced at the farm. |
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view |
---|
Strengths: increased levels of organic content. |
Slow release of nutrients. |
Better water holding capacity, especially in early spring. |
6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them
Weaknesses/ disadvantages/ risks in the land user’s view | How can they be overcome? |
---|---|
Weakness: Costs of labour | They are investing in to mechanisation of the process. |
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view | How can they be overcome? |
---|---|
Weaknesses: More labour work. | Investing in machines with larger capacity |
Risk: uncontroled release of nutrients into groundwater | They have to put lower quantity of more manure at one spreading. If they have vegetable production they can add two or three times in a year. |
