Tools used in the practice

Technology of laser planning (leveling) of irrigated land
Description of the practice and its results

Initially, the laser technology was applied to develop virgin acreage for principal land planning.  Later, it was used for routine land planning (smoothing).

In recent years, the application of laser planning technology almost stopped due to lack of resources, but this case study shows how relevant it is in the current context. 

Actions:

  • area (land) leveling (planning);
  • table-top and project design works on land planning;
  • preparation of equipment;
  • preparation of laser equipment;
  • laser land planning;
  • deep land loosening and administration of organic fertilizers.

 Results:

 Technical:

  • increased plot (KZI) ratio (up to 0.92-0.95);
  • 25-30% water saving.

 Financial and economic:

  • increased crops productivity;
  • income from planned (levelled) acreage increased from 2.17 mln sum/ha to 4.6 mln sum/ha.

 Environmental:

• improved land reclamation condition (ground water mineralization decreased, thus, leading to contraction of salinized acreage).
Lessons learnt and recommendations made

Lessons learnt:

The practice demonstrates the need for periodic (routine) laser planning (leveling) of irrigated land to enhance irrigation efficiency.

Recommendations:

For routine land smoothing, it is desirable to combine land laser planning with deep land loosening.
