ACTION:
13. The farm measures the soil humidity through the observation of soil pits.
Means of verification:
Record that shows the execution of soil pits with the following information:
- Number or code.
- Execution date.
- Area or georeferentiation.
- Deepness
- Texture (clayey, sandy, etc.).
- Results obtained (humidity level).
ACTION:
14. The farm uses efficient irrigation for the crop such as drip irrigation or micro-sprinkler irrigation.
Means of verification:
Visual inspection of the irrigation equipment used in the farm.
15. The farm does maintenance work in the irrigation and fertigation equipment periodically, at least once in the season or more often if the manufacturer recommends so.
Means of verification:
Check list or maintenance record of the infrastructure with the following information:
- Date.
- Type of event.
- Equipment/infrastructure.
- Work details.
- Responsible company/person.
If the maintenance is done by an external company, this company must issue a receipt or report certifying that the the actions carried out are in accordance with the request.
ACTION:
16. The farm programs the irrigation based on hydric balance so as to replenish the humidity deficit of the soil.
Means of verification:
Record of hydric balance with the following information:
- Date.
- Crop.
- Area or homogenous crop area.
- Weekly rainfall.
- Crop coefficient (weekly kc).
- Evo-transpiration station (ETo) showing source or information (own weather station or data portals such as http://agrolcima.cl or https:// agrometeorologia.cl/)
- Weekly irrigation time (net sheet).
- Crop evo-tanspiration (ETc).
- Hydric balance (difference between water contributions and losses).
17. The farm evaluates the uniformity of the efficient irrigation system at least once in the season and implements correction measures when the moisture coefficient is less than 85%.
Means of verification:
Uniformity record of the distribution of the efficient irrigation system that considers the following:
- Evaluation date.
- Irrigation equipment.
- Uniformity percentage.
- Recommendation.
- Corrective measures implemented if necessary.
- Responsible company/person.
If the maintenance is done by an external company, this company must issue a contract and receipt certifying the actions carried out.
ACTION:
18. The farm implements underground efficient irrigation.
Means of verification:
Visual inspection of irrigation equipment used in the farm.
19. The farm measures the humidity of the soil or the tree using probes or humidity detection technologies such as tensiometers.
or pressure bombs.
Means of verification:
Record of information of the humidity in the soil with the following information:
- Date.
- Irrigation equipment.
- Humidity of the soil or tree reported by the instrument.
- Equipment used.
- Observations.
- Responsible company/person.
If the maintenance is done by an external company, this company must issue a receipt or report certifying that the actions carried out.
