This video from the channel explains how to irrigate pastures effectively.

Here are the key points covered in the video:

Why irrigate pastures?

  • Increase fodder production, especially during periods of drought.

  • Extend the growth period of plants.

  • Maintain the quality of the grasslands.

Factors influencing pasture water needs

  • Soil type: Clay soils hold more water than sandy soils.

  • Plant type: Each plant has specific water needs.

  • Climate: Evapotranspiration (plant perspiration and soil evaporation) is higher in hot, dry weather.

Important concepts for irrigation

  • Soil water holding capacity: The amount of water that soil can hold.

  • Wilting point: The level of soil moisture below which plants begin to suffer.

  • Recharge point: The optimum soil moisture level for plant growth.

Methods for measuring soil moisture

  • Tensiometers: Measure the tension of water in the soil.

  • Humidity probes: Measure soil moisture at various depths.

  • Visual observation: Examine the soil for signs of drought.

Pasture irrigation methods

  • Sprinkler irrigation: Sprinkler system that simulates rain.

  • Drip irrigation: System that delivers water directly to the roots of plants.

  • Central pivot irrigation: Rotary system that covers a large area.

Recommendations for effective irrigation

  • Determine the effective root depth of plants.

  • Know the type of soil and its water retention capacity.

  • Identify the recharge point and the point of wilting of crops.

  • Monitor soil moisture regularly.

  • Apply water evenly and avoid wastage.

  • Do not irrigate when the soil is already saturated.

  • Allow soil to dry slightly between irrigations to encourage root growth.

  • Wait 3 to 4 days after irrigation before returning animals to the pasture.

Conclusion

Pasture irrigation can be a beneficial practice for increasing fodder production and improving grassland quality. It is important to fully understand the water needs of plants and soil in order to set up an efficient and sustainable irrigation system.
