Mycorrhizal Biotechnology Reduce Phosphorus in the Nutrient Solution of Strawberry Soilless Cultivation Systems

Abstract

Among the bio-tools that contribute to making the strawberry production system more sustainable are arbuscular mycorrhizal fungi (AMF), which can be used as biofertilizers. Thus, five doses of phosphorus (P) applied to plants with AMF and a control (100% P, no AMF) were analyzed in order to differentiate the horticultural potential of the ‘Camarosa’ cultivar. We used an on-farm inoculant made up of six fungal species. The univariate and multivariate analyses showed that the addition of AMF to the growing substrate made it possible to reduce the P supply in the nutrient solution by 75% without compromising the fruit yield. In addition, this combination improved the phytochemical quality of strawberries, the plant’s root system morphology, and the accumulation of nutrients in plant organs (roots, crowns, aerial part and fruits). We conclude that the use of a multi-species on-farm inoculant based on AMF associated with a reduction in the P supply in the nutrient solution modifies the horticultural potential of the ‘Camarosa’ cultivar. We confirmed the action of a native AMF community as a biofertilizer.

Moisture content and mycorrhizal fungi in maternal environment influence performance and composition of Lallemantia species offspring

“…Mycorrhizal fungi symbiosis with the roots of mother plants can promote the development of the root structures in soil, thus increasing the surface area for nutrient absorption. This extended root network can efficiently absorb and transport nutrients to the mother plant, ultimately benefiting seed composition [ 85 ]. The increased levels of oil, nitrogen, phosphorus, potassium, and calcium found in L. iberica in comparison to L. royleana may be attributed to the larger size of L. iberica's offspring [ 86 ].…”

Arbuscular Mycorrhizal Fungi, Ascophyllum nodosum, Trichoderma harzianum, and Their Combinations Influence the Phyllochron, Phenology, and Fruit Quality of Strawberry Plants

“…The irrigation regime was activated five times a day, with a total wetting time of 10 min. Nutrient solutions [22] were supplied to the plants weekly, with a 50% reduction in the phosphorus supply [23]. The air temperature inside the greenhouse was monitored using a mini weather station (Figure 1).…”
