8. Action of the Ministry for Agriculture, Forestry and Food (MKGP) in 2013 -
Groups for irrigation in Slovenia
Central group for irrigation in Slovenia
8 Regional groups for irrigation in Slovenia
Members: extention service, researchers, local authorities, companies that design irrigation systems, Institute for Nature Protection, etc.
Scope:
to promote irrigation
to give information
to facilitate implementation of irr. Systems
Etc.

9. Private irr. systems - example
Primer mali namakalni sistem (MNS)
Q =10 l/s at high water flow or
Q = x 0,1 l/ 24 ur per day
Small water reservoir
x 100 m3
Irrigaton from water reservoir

10. Irrigation technologies in Slovenia
Sprinkler irrigation (50 %)
Drip/micro-sprinkler (app. 50 %)
(source: SURS, 2014)

11. Irrigated areas by method of irrigation in Slovenia
In total:
2741ha (2003)
1812 ha(2005)
Tendency of the ministry for agriculture of RS

12. Približno 220.000 ha kmetijskih zemljišč, ki so primerna za namakanje.
Approximately 220,000 ha of agricultural land suitable for irrigation .

13. Vodni viri za namakanje/Water sources for irrigation
(Mokri) vodni zadrževalniki – omejitev morebitna druga raba vode - *
Vodotoki - omejitev ekološko sprejemljiv pretok (Qes) in morebitna druga raba vode - *
Surface water – restrictions is ecologically acceptable flow (Qes) and any other water use
Podzemna voda – omejitev rezervacija za pitno vodo - *
Iztoki iz čistilnih naprav – omejitev kakovost
- večinoma so znane letne količine snovi v iztoku, ne koncentracije - *
Opomba: - * potreba po pridobitvi vodnega dovoljenja
(Wet) water reservoirs – restriction is any other water use
Groundwater - the limitation is provision for drinking water
Hillel,
The effluent from WWTP
- restriction is water quality - Generally known annual quantity of the substance in the effluent without concentration
Note: - * the need to obtain a water permit

14. Vodni viri za namakanje/Water sources for irrigation in Slovenia
Ground water
Surface water
Water reservoir
Drinking water
(source: SURS, 2014)
water reimbursement in 2015
- Irrigation in agriculture = 1.5 eur/1000 m3
- Drinking watrer = 63 eur/1000 m3
- Irrigation other = 91 eur/1000 m3
the need to obtain a water permit

15. Surface water:  ha of agricultural land potentially suitable for irrigation (3km from water body, 100 m of elevation)
Water reservoirs:
32 of diff. primary use
- for additional 6 770 ha
Groundwater (shallow and deep): not used amounts (some of them are reserved – e.g. for drinking water: for additional  ha

16. Accumulation of diffuse runoff (yet unformed riverbed) = potential source of water for small irrigation systems (up to approximately 1 ha)
The location of potential water reservoir with the conjugated water catchment area.
(Fazarinc, 2011)

17. Average irr. norm in Slovenia is 2.500 (500 – 4.500) m3/ha/year
Potential winter runoff in a drought year
Average irr. norm in Slovenia is (500 – 4.500) m3/ha/year

18. Private irr. systems - example
Primer mali namakalni sistem (MNS)
e.g. Q =10 l/s at high water flow or
e.g. Q = x 0.1 l/ 24 ur per day
Small water reservoir
x 100 m3
Irrigated area e.g. 1-2 ha
Irrigaton
(directly from water course)
or from water reservoir

19. več MNS  1 VNS WATER PERMIT (24 h/day, ...month...20 years) Exaple:
VODNO DOVOLJENJE
(24 ur/dan....)
Exaple:
4 Private IrS 40 l/s ha
1 Public IrS 40 l/s npr. 40 – 60 ha
River/Reka S
U1: 10 l/s (1 ha)
When?
U2: 10 l/s (3 ha)
When?
U3: 10 l/s (3 ha)
When?

U4: 10 l/s (2 ha)
When?
U5…
More Private IrS  1 Public IrS

20. Public irr. system – example
Primer veliki namakalni sistem (VNS) Kalce Naklo
110 ha ha (265 ha)

21. Veliki namakalni sistem Kalce Naklo
8 irrigation cycles/day
18 hour/day,
2 h 15 min/cycle
Public irr. system Kalce Naklo
Q =242 l/s for 265 ha
