“…The pH and EC values of substrate mixes containing TS were higher than those of peat, rising linearly with increasing TS percentage in the SM (Table 1), in relation to the presence of alkaline elements (Ca, Mg, and Na) despite peat. These results are consistent with previous reports [12,45,46]. However, the pH values of the substrates were moderately acidic, ranging from 5.3 in TS0 to 5.8 in TS25.…”

“…In this context, by its nature, as observed in previous papers [45,46], marine sediment has an alkaline pH and could affect the nutrients' uptake by plants; however, sedimentbased mixtures composed of TS ≤ 25% in combination with peat had pH values somewhat higher than peat alone (5.3) but basically acidic, thus favouring the bioavailability of the metals in the soil [46,63]. Positively, in the current investigation, the pH and EC values observed in substrate mixes containing TS were deemed suitable for the growth of basil [64,65] and significantly lower than those reported by Ronga et al [55].…”

“…For instance, substrates with neutral to alkaline pH levels are known to limit the availability of micronutrients such as Zn, Mn, Cu, Bo, and Fe (except for Mo) and may result in deficiencies, as noted by Koc and Karayigit [60]. There are several studies available in the literature that support this observation, showing that plants grown on peat typically have a higher content of elements than those grown on compost-based substrates with higher pH levels [45,54]. Additionally, prior research has indicated that elevated levels of pH and EC in compost are the primary factors responsible for suppressing basil seed emergence [61,62].…”

Growing ‘Genovese’ and ‘Valentino’ Basil in Pots Using Peat Substrate Combined with Phytoremediated Sediment: Effects on Yield and Nutraceutical Content

Climate change is causing a decline in the availability of crucial resources such as water and fertile soil, leading to a detrimental impact on crop yields. Basil (Ocimum basilicum L.), an annual aromatic plant used worldwide for culinary, cosmetic, and medicinal purposes, is especially at risk due to its high water demand and specific growing requirements typical of the Mediterranean climate. In Italy, basil is an essential part of any herb garden and is also commonly found in households as a potted plant. Nowadays, the conventional practice of growing basil in pots with peat as the primary medium is not environmentally sustainable, which underscores the need for alternative and sustainable cultivation techniques to ensure the continued growth of this majestic king of herbs. A greenhouse factorial experiment was conducted to study the impact of peat replacement and reduced water supply on the growth and biochemical traits of basil plants. The study included two cultivars (‘Genovese’ and ‘Valentino’), three substrate mixes with phytoremediated dredged sediment (TS) at varying volume percentages (0%, 12.5%, and 25%), and three levels of water irrigation (normal, reduced by 25%, and reduced by 37.8%). Increasing the TS percentage resulted in higher germination rates and greater biomass production in both cultivars compared with the control. ‘Valentino’ potted plants produced a higher yield than those of ‘Genovese’, while the latter had higher pigment contents due to its genetic characteristics. All combinations of substrates mixed with the highest water amounts of irrigation positively impacted seed germination and biomass-based outputs, while control peat with reduced water availability led to lower plant yields and germination capacity. Substrates with TS had suitable physicochemical characteristics for plant development. Our findings suggest that using peat–TS mixtures can produce quality results comparable to or even better than conventional soilless culture using only peat. Thus, replacing peat with moderate percentages of TS can be an effective and sustainable practice for recycling phytoremediated sediments.

“…In the case of evergreen cherry laurel, the TS used in proportions of 2550% reduced plant height growth, especially when combined with wood fibre, slightly altering its attractive vibrant foliage. This species is easy to care and adapts to most types of soils, from light and sandy to heavy clay; thus, the reduced plant development was assumed to be pri marily associated to the combined properties of the used matrices (Tozzi et al, 2022).…”

Carried out within the LIFE17ENV/IT/000347-SUBSED project, this research aimed at investigating the effect of a treated sediment (TS) as substrate component on the quality and marketability of three widespread containerized ornamental species: cherry laurel (Prunus laurocerasus) cv. Novìta, calla lily (Zantedeschia aethiopica) and protea (Protea cynaroides) cv. Little Prince. The TS was mixed with soilless substrates as sphagnum peat, coir, and bark in different proportion (0%, 25% and 50%). In cherry laurel, the TS used in 25 - 50% proportions reduced plant height, slightly altering its attractive vibrant foliage. A positive effect of the TS was evidenced on calla lily, where both tested sediment-based mixtures allowed a copious blooming and flower quality raised as the sediment content increased (TS 50% > TS 25% > TS 0%). Post-harvest longevity and colour of flowers were not affected by substrate composition. The effect of sediment-based substrates on protea growth and blooming showed an opposite trend (TS 0% > TS 25% > TS 50%), with plants grown on 50% v/v TS exhibiting a considerable reduction in plant growth and production of flower clusters, with brighter tones turning towards purple. Based on sale values, the TS proved to be a sustainable alternative for the production of potted ornamentals if properly mixed with other organic matrixes, such as peat and coir.
