Soilless cultivation is becoming increasingly popular in Mediterranean countries, but one of the main challenges faced by horticulture in many of these regions is the low precipitation<\/b>, which limits the availability of water for irrigation.<\/p>

Fertigation discharge worsens existing water scarcity conditions, as in open hydroponic systems, the drainage of the nutrient solution commonly exceeds 30% of the total applied. Proper management of the nutrient solution<\/b> is essential to avoid water waste.<\/p>

It has been reported that the concentration of currently used nutrient solutions can be reduced by up to 50%<\/b> without negative effects on biomass or on the quality of horticultural and ornamental crops.<\/p>

One way to reduce nutrient use without compromising crop productivity in hydroponic production is to enhance nutrient absorption<\/b> by plants through the use of biostimulants<\/b>.<\/p>

Biostimulants can also reduce fertilizer consumption by promoting a more efficient absorption<\/b> of nutrients.<\/p>

The most widely accepted definition of a plant biostimulant is:
\u201cAny substance or microorganism applied to plants with the aim of improving nutrient efficiency, tolerance to abiotic stress, and\/or crop quality characteristics, regardless of nutrient content.\u201d<\/b><\/p>

The main categories of biostimulants include:<\/p>

  • humic substances<\/li>
  • protein-containing materials and protein hydrolysates<\/li>
  • seaweed extracts (such as Ascophyllum nodosum)<\/li>
  • beneficial fungi and bacteria<\/li><\/ul>

    Biostimulants can be used at all stages of agricultural production<\/b>, including seed treatments, foliar applications during growth, and on harvested products.<\/p>

    Various biostimulants have been shown to stimulate plant growth<\/b> by boosting plant metabolism, promoting germination, improving photosynthesis, and optimizing nutrient uptake from the soil or growing medium.<\/p>

    They can also mitigate the negative effects of abiotic stress<\/b>, such as drought, heat, salinity, cold, and oxidative stress.<\/p>

    The use of biostimulants represents a sustainable and promising<\/b> strategy to optimize crop productivity, especially in hydroponic systems. Their integration into agronomic management is a key to more efficient, resilient, and environmentally respectful agriculture<\/b>.<\/p>
