Effective irrigation in periods of drought: what you need to know

Prolonged drought is one of the major challenges for farmers, gardeners and farmers. The lack of rainfall affects not only the quantity, but also the quality of the crops and o irrigation Inevalent can lead to important losses. Therefore, it is essential to understand how to use water responsible and intelligently, in order to support plants even in the most arid periods. Discover in our article how to create effective irrigation during drought periods, in order to support agricultural crops.

Why is an effective irrigation strategy important during periods of drought?

In periods of drought, every liter of water is important. A chaotic or superficial irrigation can accentuate the water stress of the plants, favoring the drying of the roots, blocking nutrients in the soil or even the beginning of diseases. Instead, well planned irrigation:

• stimulates the development of deep roots,
• Prevents quick evaporation of water,
• Reduces the useless consumption of resources,
• It supports a healthy and balanced harvest.

The most effective irrigation methods in drought conditions

1. Driving irrigation

Considered the cheapest irrigation method, the drip system provides water directly at the root level. Therefore, the losses by evaporation are reduced to a minimum and precise control of the water flow is guaranteed. It is ideal for gardens, greenhouses, solariums or vegetables and fruit trees.

2. Race irrigation (basin)

For fruit trees or shrubs, a simple method is to create a pit around the stem, in which the water is paid directly. This allows the infiltration of slow water and avoids the surface irrigation that encourages the development of the roots on the surface.

3. Irrigation on grooves

Used above all in traditional agriculture, it involves the direction of water through the channels dug between the ranks of the plants. It is effective if the soil is well leveled and the ground has a good water retention capacity.

When and how much do you have to use plants?

During hot periods, the moment of irrigation is essential. The best hours for irrigation are:

• early morning (before 9) – when the temperatures are low and the evaporation is minimal;
• In the evening (after sunset) – if the ground is very dry, to prevent thermal shock.

The frequency of irrigation depends on:

• Type of soil (sandy = more frequent irrigation; clay = more rare but abundant),
• age and type of culture,
• The stage of the development of plants (young plants need more water),
• climatic conditions.

In general, it is more effective and deeply effective than often and superficial.

How do water losses are reduced?

1. Land Mulcation

A layer of organic package (straw, leaves, cortex, compost) reduces the evaporation of water from the ground, stabilizes the temperature and suppresses the weeds that compete for water.

2. Control of weeds

The weeds consume a significant amount of water. Keeping the earth clean helps to preserve humidity for cultivated plants.

3. Choose drought resistant varieties

For areas frequently affected by drought, opt for plants and varieties adapted to arid conditions, with a reduction in water needs.

Frequent errors to avoid for effective irrigation in periods of drought

Here are the main errors to avoid for effective irrigation during drought periods:

• Daily and superficial watering, which encourages the formation of a weak radical system.
• The use of cold water in full sun, which can heat the plants.
• Irrigation of leaves in hot periods, which can cause burns or promote fungal diseases.
• Ignore the water quality: hard or contaminated water can negatively influence the soil and plants.

Conclusion

Effective irrigation in periods of drought does not only mean «watering plants», but to support them intelligently, with minimal resources, for maximum efficiency. Choosing the right method, the programming of irrigation, the optimization of consumption and the adaptation to soil and culture conditions are essential steps in the fight. With careful management, you will not only save plants, but you will build a more sustainable and resistant agricultural system.
