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.

Protocol Mugavero on Fennel

Fennel is one of the few items in the fruit and vegetable supply chain to be produced in Italy and has no foreign competitors on the shelves of large-scale distribution. The increase in raw material costs, both in the fields and in the warehouse, is penalizing the fennel supply chain. Plastics, paper, and wood have undergone significant increases, up to 50-60%.

Making a difference in the field by reducing waste and improving quality is certainly a challenge to be taken up, in a market that is increasingly attentive to pesticide residues.

Biostimulants and Resistance Inductors

Mugavero proposes a fertilization plan for fennel that provides for the foliar application of biostimulants and resistance inducers.

Radico Gel

In the post-transplantation it is suggested to intervene with RADICO GEL at a dose of 5 liters per hectare: thanks to its gel formulation it guarantees persistence on plant tissues and as well as providing phosphorus to favor root development it completes the nutritional requirement of meso and microelements.

Macal and Canta

During the growth of the clot, weekly foliar treatments in a mixture of MACAL together with CANTA are recommended at doses of 5 liters and 2.5 liters per hectare respectively. If MACAL satisfies the needs of the crop in calcium and magnesium, CANTA reduces abiotic and biotic stresses by amplifying the nutritional response and vegetative development.

Statia and Tocuzin

The application of MACAL and CANTA can be alternated with the application in a mixture of two resistance inducers, STATIA and TOCUZIN to be used at a dose per hectare of 5 liters and 2.5 liters respectively. STATIA guarantees energy supply and healing action of the herbaceous tissues of fennel, TOCUZIN health protection from fungi and bacteriosis thanks to the cytotropic action of zinc and copper. Together they guarantee crop health appreciated by the field operator, guaranteeing a “zero residue” product that complies with the quality standards of the large-scale distribution.

Supra

In the lump enlargement phase, at 3/4 of the cycle, to complete the development of the plant, it is recommended to apply SUPRA at a dose of 10 liters per hectare.

The final result of the suggested protocol is an article having size and homogeneity of lump size. At the same time, an absence of rot inside the lump is guaranteed. The waste at the time of harvesting is almost nil.

Hour x is upon us. To obtain an early production, in the table vineyards in a protected environment it is almost time to stop for a moment and think about how to obtain a loose and “quality” bunch, with a well-stretched rachis and with the right number of berries. Aspects have always been sought after and pursued by winemakers to bring the best possible table grapes into their homes.

Table grapes: Mugavero’s advice

When you are struggling with table grapes and want to stimulate the relaxation of plant tissues, Mugavero recommends carrying out a first foliar treatment in the pre-flowering phase with Canta, the innovative biostimulant product of Mugavero Research which, on grapes from the table, gives excellent results in terms of distension of the bunch and swelling of the berries.

Containing an organic matrix readily assimilable by plant tissues and bioactive molecules produced by Streptomyces sp. Bacteria, Canta, applied by foliar but also root, ensure prolonged effect overtime on the development of the productive organs of the plant. Promoting, at the same time, the vegetative-productive development, and strengthening the root and vascular system, even in conditions of biotic and abiotic stress.

But that is not all. To promote a significant swelling of the berries, Mugavero recommends a second application of Canta also in the post-fruit setting phase. In such a way as to have excellent and undisputed results that, over the years, have received the appreciation of winemakers, who no longer have to resort to the use of synthetic molecules or mixtures of different products.
