Prepare to mitigate the effects of La Niña

According to NOAA's climate information analysis, the fourth quarter of 2016 would be under conditions of a new La Niña phenomenon.

Recommendations for the management of sugarcane cultivation in conditions of excess soil moisture.

- Facilitate the exit of water from the crop:

  • Clean and collect ditches and collectors.
  • Make sure the good condition and cleanliness of the drainage pipes.
  • Remove plugs at the end of the grooves.
  • Verify the free discharge of drainage ditches to the collectors.
  • Check the condition of vases or dikes: cover cracks, clean and control anthill.
  • Have motor pumps to evacuate water from the flat areas adjacent to the rivers.

- Reduce the negative effect of machines on the ground:

  • Avoid overweight equipment and excessive skating.
  • Control machine traffic.
  • Perform only superficial tillage to establish the crop and leave deep work for when the humidity decreases.

- Use high clearance tractors to get jobs done in a timely manner

- In areas with slow drainage and susceptibility to waterlogging:

  • Implement the sowing practice in the loin.
  • Make high aporque in established crops and in socas.

- Check the types and doses of fertilizers suitable for soils with excess moisture:

  • Replace urea with nitrogen-containing fertilizers in nitric form (ammonium nitrate and UAN solution).
  • Use ammonium nitrate and UAN solution only if there is no risk of being washed by leaching or runoff (when sowing on the spine and / or performing high cork). It is preferable not to use any type of fertilizer in these extreme conditions.
  • Apply the ammonium nitrate and UAN solution, in smaller doses than those used in conditions with normal humidity and near the strain.
