Mediterranean Agriculture Under Pressure: Combating Salinity with Biotechnological Innovation

In recent years, Mediterranean agriculture has been facing an increasing number of environmental challenges linked to climate change. Among the most critical issues are rising average temperatures, irregular rainfall patterns, and increased evapotranspiration—phenomena that are progressively altering the availability and quality of water resources. The most affected areas are open-field crops and high-value agricultural zones, where water scarcity and rising salinity are becoming major constraints on productivity.

In this context, the use of saline water for irrigation has become, for many farms, more of a necessity than a strategic choice. Ongoing saltwater intrusion, the reliance on deep wells, and limited access to fresh water are forcing producers to deal with high levels of sodium and other saline elements that are harmful to both soil and crops.

The Effects of Salinity: Soil, Plants, and Profitability Under Stress

Excess salt—especially sodium—causes several agronomic issues. In soil, salinity impairs structure, reducing permeability and leading to compaction, which hinders proper water infiltration and circulation. At the crop level, sodium competes with essential cations such as calcium (Ca²⁺), magnesium (Mg²⁺), and potassium (K⁺), limiting their absorption by plant roots. This results in weaker plants, stunted vegetative growth, lower yields, and in severe cases, early root system failure.

Not all types of salinity are the same: it’s essential to distinguish between salt accumulation (neutral salts like carbonates and chlorides) and sodic salinity, which involves excess exchangeable sodium in the soil. The latter is particularly harmful to tree and vegetable crops, as it deeply disrupts nutrient dynamics and subjects plants to osmotic and physiological stress.

Technological Solutions: Effective but Not Always Accessible

To counteract salinity, advanced technologies such as reverse osmosis systems are available, which can reduce the salinity levels of irrigation water. However, these systems are energy-intensive and financially out of reach for many small and medium-sized farms. Some producers have turned to alternative methods, such as using artificial reservoirs to mix saline water with rainwater, temporarily reducing electrical conductivity. While these measures provide short-term relief, they do not address the root causes nor do they remediate already compromised soils.

SINSAL: The Biological Technology That Regenerates Soil and Crops

In response to these challenges, Mugavero has developed SINSAL, a biological water and soil corrector based on M.A.S. (Microbial Synergistic Action) technology, designed to tackle salinity in a natural, integrated, and effective way.

SINSAL stands out for its dual synergistic action:

• Chemical Action: Thanks to the presence of calcium lignosulfonates—compounds that bind sodium and reduce its availability in the soil—SINSAL helps improve soil structure and restore its cation exchange capacity.

• Microbial Action: Through a consortium of halophilic bacteria (salt-loving microorganisms), SINSAL performs multiple biological functions: sequestering excess sodium, solubilizing phosphates, and stimulating the production of siderophores—molecules that enhance the plant’s uptake of micronutrients.

This biological approach not only mitigates the effects of salinity but also regenerates the soil microbiome, making the root environment more active, balanced, and productive.

Case Study: Citrus Growers in Ribera (AG), Sicily

One of the clearest examples of SINSAL’s effectiveness comes from the Ribera area in the province of Agrigento, renowned for its Ribera IGP Oranges. When the local irrigation network cannot provide adequate water, citrus growers are forced to irrigate using water from the Magazzolo River or private wells, often containing sodium concentrations between 400 and 750 mg/L.

Considering that the recommended sodium threshold for citrus irrigation is 100 mg/L, with critical limits above 200 mg/L, this scenario is highly concerning.

Thanks to the use of SINSAL in fertigation, these farms have been able to:

• Lower the electrical conductivity of both water and soil,

• Significantly improve soil structure,

• Eliminate visible salt stress symptoms on plants,

• And most importantly, achieve higher-than-expected yields, even during dry years.

A New Alliance Between Agriculture and Biotechnology

In conclusion, SINSAL offers a practical, affordable, and sustainable solution for farmers operating in salinity-prone regions. It’s a valuable ally for those seeking to restore soil productivity, improve crop resilience, and protect profitability—without resorting to high-cost or environmentally taxing technologies.

Agricultural biotechnology can—and must—support sustainability and regeneration. SINSAL is a shining example of this potential, capable of bringing life, balance, and prosperity back to soils threatened by salinity.

The effect of climate on cereal crops

The ups and downs of the climate inevitably have repercussions on the yield and quality of the autumn-winter cereal crops which are traditionally grown dry. There are tools available to the field operator to allow the achievement of the best quantitative-qualitative result: the use of technologically innovative fertilizers on the one hand, agronomic techniques on the other, in a global management perspective according to the principles of ‘agriculture 4.0: thanks to the application of digital technologies, farms, especially those that deal with cereal crops, can increase profit, economic and environmental sustainability.

It is a fact that the farmer must respect the time windows useful for each cultivation operation by integrating takeaways with targeted and balanced nutrition in respect of soil fertility and at the same time be timely in the treatments to be carried out.

It is necessary to work, for the different production areas at different latitudes, on a shared supply chain path, achieving common objectives in quantitative/qualitative terms; the awareness remains that the productions in Italy of areas suitable for wheat are still insufficient to satisfy the needs of the Italian pasta industry.

The Mugavero protocol on cereal crops

The Mugavero production protocol for cereal crops presents consolidated results in terms of yield-quality combination and provides for the use of “slow release” nitrogen fertilizers with a high technological level such as the MIDOTEC line and the AUREA line respectively for bottom fertilization and cereal cover.

Midotec

The fertilizers of the Midotec line contain the 3.4 DMPP inhibitor of soil bacteria responsible for nitrification, therefore they must be buried to best express the characteristics of the fertilizer.

Aurea

Unlike the traditional nitrogen fertilization with urea that the farmer carries out “running” after the rains, the use of the Aurea fertilizer containing the urease inhibitor NBPT makes it possible to program the fertilization comfortably, regardless of the onset of rain cover nitrogen. Aurea also has the further advantage of canceling the nitrogen losses due to volatilization that occurs with the distribution of urea.

Canta and Supra

The protocol also includes a biostimulant, CANTA, and a foliar fertilizer, SUPRA.

Canta is recommended for application with weed control to reduce the stress of the herbicide on the plant; it promotes the development of roots and allows for a better-structured plant and ear. Supra has instead been studied for foliar application to complete the nitrogen requirement of the crop in the last stage of crop growth. Unlike other formulations, Supra can be used at high doses per hectare without the risk of creating phytotoxicity, even when mixed with fungicides. The application of Supra ensures, in all circumstances, the achievement of a satisfactory protein content.

In September transplants for open field crops and for those in a protected environment, the time has come, after the plant has overcome the transplant stress and is in the middle of the vegetative phase, to think about reinforcing the vegetative organs to reduce the susceptibility of itself to fungal diseases before temperature fluctuations catch the crop off guard. Any “higher” autumn thermal values ​​also end up favoring vegetative growth by putting the plant into vegetation when instead it is time to promote flower differentiation.

We also remember that, with the arrival of winter, the soil temperatures will slowly drop; temperatures below 18 ° C reduce the plant’s ability to assimilate phosphorus, so what the plant had accumulated must be enough for the completion of the production cycle. However, it often happens that the plant goes into an energy deficit: in the cauliflower or broccoli plant, for example, the release of the flower head is delayed.

Mugavero takes the field with STATIA to solve these problems; it is a resistance inductor enriched with lignosulfonates specially designed for foliar application to give new energy to the plant.

STATIA performs a triple action: it nourishes the plant, thickens the leaf blade, and makes it less susceptible to attack by fungal diseases by shifting the source-sink balance towards production. An integrated defense strategy, it makes it possible to significantly reduce the number of pesticides that can be used for the fungicide defense against powdery mildew, downy mildew, and botrytis. It can be mixed with all formulations on the market, it also has a healing action: after a hailstorm, for example, it is desirable to intervene with STATIA for rapid healing of damaged tissues.

Used regularly from 3 to 5 times during the normal vegetative-productive cycle, it allows obtaining a plant with a beautiful green color and healthier. The best structure of the leaf and therefore of the plant results in a more homogeneous and performing plant in terms of production.
STATIA does not create residues and has no shortage times, allowing for regular harvesting, a very important aspect for these types of crops.

The increase in business management costs nowadays requires particular attention to autumn and winter fertilization; from this point of view, the foliar application comes to the aid of the farmer by representing an “economically” valid choice with very high efficiency.

GRAN RISERVA

Gran Riserva is a foliar biostimulant that provides the plant with the “energy” necessary to complete the phylloptosis and maturation of the wood; it allows the plant to “rest” at its best by intervening when it is time to slow down the vegetative activity and accumulate the reserve substances essential for the next year’s production cycle.
The correct accumulation of reserve substances is evident, in many cases, with an evident swelling of the bud, especially on some fruit species such as stone fruit and kiwi: the plant thus treated quickly acquires greater resistance to biotic and abiotic agents, improving resistance to cold and to pathogens. This is made possible by the presence of lignosulfonates which give the product marked surfactant and sequestering properties with regard to the microelements present (Zn and Mn).

Gran Riserva is applied post-harvest: it is also effective on already defoliated branches as it is absorbed by the cell walls of the wood and bud, also exerting a healing action.
According to the vegetation cover:
Use the highest dosage if the plant has not yet lost its leaves (LAI equal to 1);
Use the lowest dosage if the plant has lost at least 50% of its leaves (LAI equal to 0.5).

LAI (Leaf Area Index): Leaf area index, a measure of the leaf area per unit of soil surface.

The barattiere is an ecotype of the Cucumis melo L. species typical of the Apulian area south of Bari, widespread between the territories of Polignano a Mare (BA), Monopoli (BA), and Fasano (BR).

The edible part of the cultivated vegetable has intermediate qualitative characteristics between cucumber and melon and is represented by the immature fruit that is normally consumed as an alternative to cucumber, compared to which it is more digestible due to the absence of cucurbitacin.

This “niche” vegetable crop is included in the list of Traditional Agri-food Products (PAT) of the Puglia Region.

The planting of the Barattiere takes place by direct sowing or transplanting in the open air, in small tunnels, or in a greenhouse to anticipate or delay the harvest from spring to early autumn. The plant takes on a garment appearance with dark green, thin stems, and very long internodes and produces an average of 6 to 12 fruits per plant. Harvesting is done by hand, gradually when the fruits have a firm and crunchy pulp.

What does Mugavero Fertilizers recommend for the Apulian Barattiere?

Mugavero recommends intervening with Niger L to improve the vegetative-productive growth from transplantation to fruit set and with Niger 700 to promote the enlargement of the peponide.

Niger L is a physioactivator with a high concentration of fulvic acids extracted from Leonardite and is characterized by an acid pH that improves its penetration into plant tissues: used both by foliar application and for fertigation at the label dose, alone or in a mixture. , it can be included in conventional cultivation programs to promote cell distension and the development of both biomass and root systems; the treated plant improves by vegetative-productive growth and therefore the yields in both qualitative and quantitative terms: NIGER L stimulates the early and vigorous development of the roots, the vegetative drive ensuring a prolonged vegetative-productive activity over time.

NIGER 700, on the other hand, is particularly suitable in the phases of fruit enlargement and ripening: with the presence of humic and fulvic acids and a not indifferent mineral component, consisting of Nitrogen (both in ammonia and nitric form), Phosphorus, Potassium and chelated microelements, the NIGER 700 turns out to be the extremely complete product for plant nutrition.

Applied in fertigation, it allows to obtain a more compact plant with shorter internodes and particularly resistant to biotic and abiotic stresses; it also provides the plant with the correct boost to accelerate the fruit “ripening” processes.

To the continuous demand for more performing technical means for agriculture, Niger L and NIGER 700 certainly represent a concrete answer for their high nutritional and economic efficiency, as they are capable of making “zero residues” quality agriculture sustainable.

To counteract the tired ground or the root system with a compressed functionality, Mugavero deploys Niger 650 in the initial budding phase of the kiwi. An effective solution is characterized by a particular formulation containing total humic extracts (2.1%) with a sub-acid reaction

When to give Niger 650 for kiwi

To support the kiwi on the tired ground, Niger 650 is administered by fertigation in two applications 10 days apart. As the radical treatment immediately induces the emission of new roots, stimulating a response that is visibly milder on the epigeal part. In this way the kiwi plant gradually regains vigor and in the long term, in production, it releases an extra boost.
The vegetation of the kiwi plant treated thus becomes darker and takes on greater brilliance. Providing a definitely guaranteed production result. But that is not all. To improve the effectiveness of Niger 650, Mugavero recommends adding Aswell to fertigation. It is an organic product that allows to improve the absorption of soil micro and macronutrients and, at the same time, enhances and improves the cation exchange capacity of the soil.

Vegetable crops

During the winter, vegetable crops in a protected environment are subject to problems of maturity and colouring of the fruits, due to differences: from low light, up to high humidity and waiting for the photoperiod. Factors which, as in the case of pepper and tomato, cause the depreciation of the finished product. This is why Mugavero, which has always been attentive to these problems, offers a range of highly professional products, capable of sustaining harvest times and improving the quality and colour of the final product.

STATIA

With an innovative formulation with zero residue, readily assimilable and completely soluble, Statia allows the thickening of the leaf plate in periods in which the root of the plant, due to low thermal values, does not assimilate correctly. In the phenological phases, in which there are high requirements in phosphorus and potassium, the foliar application of Statia, therefore, represents valid support for fertigation, increasing the solute content in the vegetable tissues and therefore the plant’s defences from low temperatures. Furthermore, close to veraison, it promotes the synthesis of sugars and the degradation of acids in the very early stages.

MUGASOL GEL MATUR

Another Mugavero that allows you to protect vegetable crops problems or protect the environment is undoubtedly Gasol Gel Matur which, is equipped with a particular formulation, which allows high adhesiveness and persistence of the product on the leaf blade. Furthermore, its very composition allows an ideal nutritional supply to favour the contribution of the fruits.

UPPER GROW

Organic biostimulant rich in potassium, Upper Grow, with its foliar application, allows rapid absorption and immediate response on the colour of the fruit. Furthermore, since it can also be applied in fertigation on conventional systems, Mugavero suggests application to Niger 700, water-soluble NPK with humic and fulvic acids, at the combined doses of 0.2 l and 5 kg per 1000 m2 respectively.

August is now a memory and with the arrival of September, pepper cultivation returns to the fore. In protected cultivation, in the context of the Mediterranean area, the cultivation of peppers stands out for its yields and sustainability. Consequently, using a performer fertilizer means the costs of managing the crop with an assured final result and amortization.

This is why, for the cultivation of pepper, the Mugavero biostimulants line becomes fundamental, which includes a range of highly professional products that can also be used in organic farming. In conditions of water stress, the crop is more subject to apical rot: calcium, an important component for the structure of the cell walls, is not translocated in these stress conditions and the plant can also show internal chlorosis and necrosis of the leaf margin in correspondence of the vegetative apexes, which can even dry up. In fact, calcium directly affects the salt balance in plant cells and potassium is activated to regulate the opening and closing of the stomata and to allow the movement of water in the plant.

Mugavero’s solutions for pepper cultivation

Going into the merits of the solutions from Mugavero for the cultivation of peppers, from the fruit set phase to the pre-harvest phase, foliar applications of Tonical are suggested, a fluid formulation containing calcium complex with amino acids and peptides more easily conveyed inside the cell membrane. As, in the organic component Tonical also has extracts of brown algae (Ecklonia maxima) very rich in phytohormones, in particular auxins, obtained by cold extraction.

On the other hand, to improve the colour of the peponide and support the plant during production, we recommend the application of Upper Grow, a liquid biostimulant rich in potassium and organic nitrogen indicator to also increase consistency and shelf-life. Applicable both foliar and in both fertigation; In the second case, Upper Grow contributes to improving the physicochemical properties of the soil by increasing the nutrient availability in the circulating solution and improving the exchange capacity of the soil system.

The Mugavero line for quality Lettuce:

In leafy vegetables, the characteristics that recognize their quality are consistency and crunchiness and above all shelf-life. The MUGAVERO biostimulants line for lettuce cultivation includes a range of highly professional products that can be used in organic and / or zero residue. To cope with calcium deficiencies in conditions of water stress, MACAL is proposed, a formulation based on readily assimilable calcium and magnesium to be applied by foliar application. While calcium directly affects the salt balance in plant cells and activates potassium to regulate the opening and closing of stomata and to allow the movement of water in the plant, magnesium guarantees the promotion of photosynthetic activity and a greening of the fabrics.

MACAL must be applied from the phase of vegetative development to immediately before harvesting alone or in a mixture of aMUGASOL MIX L, a product based on chelated microelements with an organic chelator that allows rapid absorption at the vascular level.

STATIA is a new PK formulation with zero residues indicated for structuring the leaf, improving resistance to abiotic agents, and also with healing action. STATIA is indicated during the whole cycle of the plant in a mixture of pesticides and other biostimulants.

To complete the foliar nutrition there is MUGASOL GEL in different formulations (PLANTA 20.20.20, RADICO 11.40.12, MATUR 10.10.31) which improve the color of the plant in terms of brightness and intensity.

CANTA is one of the newborns of MUGAVERO and belongs to the category of “activators of the rhizosphere”; organic biostimulant containing a consortium of bacteria that promotes the vegetative-productive development of the plant. Administered via the leaves and by fertigation, it strengthens the root and vascular system of the plant even in conditions of biotic and abiotic stress.
