Bio‐based products are nowadays useful tools able to affect the productivity and quality of conventionally cultivated crops. Several bio‐based products are currently on the market; one of the newest and most promising is the wood distillate (WD) derived from the pyrolysis process of waste biomass after timber. Its foliar application has been widely...

Full-text available
Wood distillate (WD) is a bio-based product applied to crop plants for its known action on growth promotion and yield enhancement, but studies are lacking on its effects on the germination of arable plants. To test such effects, we applied WD at six different concentrations on the diaspores of three threatened arable plants: Bromus secalinus, Centa...

The growing interest in bioplastics and bio-based crop management products in agriculture is driven by the Sustainable Development Goals of the 2030 Agenda. However, recent research has raised concerns about the sustainability of bioplastics due to their potential negative impact on crop growth and yield, with implications for the environment and h...

Boron (B) is a crucial micronutrient needed for plant growth. This study investigated the effect of B addition (0.5 mg kg-1-low, and 5 mg kg-1-high) on lettuce (Lactuca sativa L.) plants grown in the soil and hydroponically. The results showed that B addition causes a differential increase in lettuce leaves depending on the cultivation system. Soil...

Potato is the fourth most widely consumed staple food in the world. This study investigated the effectiveness of 0.2% wood distillate (WD), a biostimulant derived from the pyrolysis of waste plant biomass, in boosting the nutritional quality of potato tubers. The results showed that application of WD significantly increased the content of soluble s...

This study evaluated the genotype by environment interactions in the yield and nutraceu-tical traits of the orange-fleshed sweet potato (OFSP) storage root in different agro-climatic zones of northern Ethiopia. Five OFSP genotypes were cultivated at three different locations following a randomized complete block design, and the yield, dry matter, b...

As a consequence of the Russian invasion of Ukraine, Europe is facing a shortage of chemical fertilizers for agriculture. Therefore, the use of byproducts of biomass anaerobic digestion, e.g., solid (SD) and liquid (LD) digestate, could be a key solution to cope with this problem. In this framework, the present study aimed to evaluate the effect of...

Simple Summary This study aimed to investigate the influence of the agro-climatic environment of Northern Ethiopia on the content of essential mineral elements of selected orange-fleshed sweetpotato genotypes, the potential contribution of each genotype’s essential mineral elements to the required daily allowance, and the potential risk to human he...
Article

This study investigated the effect of soil contamination by different concentrations of gasoline on oat (Avena sativa L.) and tested the effect of biochar supply to the polluted soils on the performance of oat plants. Oat seeds were sowed in contaminated soils with different concentrations of gasoline: 0% (control), 1%, 2%, 6%, and 10% (v/w), and g...
Article
The recent use of bioplastics in agriculture is considered an ecological choice, aimed at limiting the environmental impact of plastics, in line with the Sustainable Development Goals of the United Nations. However, the impact of bioplastic residues on the environment is unclear as knowledge is lacking. This is the first study investigating the eff...

Wood distillate (WD) is a bio-based product stimulating plant growth and yield, environmentally safe, and allowed in Italy in organic farming. To the best of our knowledge, there are no studies on the effects of WD on spontaneous plants growing among crops, including their functional traits like biomass. To test such effects, we carried out a lab e...
Article

In the quest for eco‐friendly products with biostimulant properties, foliar application of wood distillate (WD) was tested on the growth and yield of chickpea (Cicer arietinum L.). Wood distillate (pyroligneous acid) is a by‐product of plant biomass pyrolysis and is rich in biologically active substances like polyphenols, alcohols, acids, and ester...
Article
Full-text available
This study investigated the effect of two different methods, i.e. air-drying and freeze-drying, of preservation of elephant garlic (Allium ampeloprasum L.) cultivated in Valdichiana, a traditional cultivation area of Tuscany, Italy, on its nutritional characteristics (i.e. soluble proteins. polyphenols, flavonoids, free radical scavenging activity,...
Article

This study examined whether foliar applications of wood distillate (WD) have a protective effect on photosynthesis and the antioxidant power of lettuce when exposed to an ecologically relevant O3 concentration. Seedlings of lettuce (Lactuca sativa L.) were fumigated daily with 60 ppb of O3 for 30 days, five hours per day. Once per week, 50% of the...

Bio-stimulants are showing growing success and are gradually replacing synthetic fertilizers in agriculture. Wood distillate (WD), also known as wood vinegar or pyroligneous acid, is a by-product of biomass pyrolysis and is increasingly used as a bio-stimulant for crop production. This study investigated whether weekly foliar applications of 0.25%...

This study investigated the dynamics of the accumulation and release of Hg 2+ in lichens, using Evernia prunastri (L.) Ach. as a model species. Thalli were incubated with solutions containing 1, 10, and 100 µM Hg 2+ and then exposed for 1, 2, 3, 6, 12, 18, and 24 months at the Botanical Garden of the University of Siena (a location free from local...

In the Valdichiana area (Tuscany, Italy) an ancient native landrace of elephant garlic (Allium ampeloprasum L.), locally known as “Aglione della Valdichiana”, has long been cultivated. The aim of this study was to check whether there are differences in the mineral and nutraceutical profiles of the Aglione della Valdichiana cultivated conventionally...

In this study, the release of Cu ²⁺ and Zn ²⁺ was investigated and modeled in the epiphytic lichen Evernia prunastri. Samples were incubated with solutions containing these metals at ecologically relevant concentrations (10 and 100 μM) and then transplanted to a remote area and retrieved after 1, 2, 3, 6, 12, and 18 months. The results showed that,...
