“…Over the last 20 years, polysaccharide-based fertilizers have gathered significant consideration in the frame of EEFs. By being biodegradable, non-toxic, water-soluble, swellable, easily chemically modified and by increasing the disposal of nutrients, polysaccharide-based fertilizers are gaining a title role in agricultural practices [5]. Polysaccharides have further been used in several agricultural practices, such as in plant protection against biotic and abiotic stresses and in recovery of contaminated soil and water [6], in plant seed priming [7] and in improvement of plant product quality and bioactivity [8].…”

Origanum dictamnus L. (Lamiaceae), a local endemic plant of Crete (Greece), creates polysaccharide-containing subcuticular compartments presenting biological activity against phytopathogenic fungi, and, among others, significantly affects the fungal cell wall polysaccharides. This field study introduces a fertilization scheme for O. dictamnus, which was developed and refined to optimize the yield as well as critical herbal quality aspects. Five fertilization schemes were investigated, based on a polysaccharide-based Integrated Nutrient Management (INM), a mixture of conventional inorganic fertilizers (ChF) and two biostimulants (not algae) via foliar and soil application. Plant growth, together with leaf chlorophyll fluorescence and color (SPAD meter, DA meter, Chroma Meter) were determined. The leaf content of chlorophyll, three critical antioxidant compounds (carotenoids, flavonoids, phenols) and nutrients were also assessed. Considering all three antioxidants together, the enhanced efficiency, non-toxic, water-soluble, polysaccharide-based INM by foliar application was the most stimulatory scheme, playing an important role in plant growth and development. The present field study provides, for the first time, baseline fertilization data improving key herbal quality features in O. dictamnus and unravels the attainment of high antioxidant properties. The latter may be exploited in favor of its further utilization as a raw material for tea preparation, medicinal purposes, natural food flavoring and/or food preservative.

“…8 Degradable polymer materials include both synthetic polymers such as poly(lactic acid) (PLA) and poly(vinyl alcohol) (PVA) 9 as well as natural polymers such as lignin, sodium alginate, and polysaccharides. 8 To achieve excellent slow-release functionality and reduce the cost, a variety of polymers have been widely used in combination. For example, PLA/lignin, 10 PVA/cellulose/sodium alginate, 11 sodium alginate/ammonium lignin 12 and other nutrients.…”

Mulch film and slow-release fertilizers are widely used in agriculture and horticulture, and it has become a trend to use degradable materials for the preparation of mulch films using slow-release materials. However, most degradable materials have poor performance or relatively high cost. In this study, three types of degradable materials, namely, poly(vinyl alcohol) (PVA), corn starch (CS), and alkali lignin (AL), were used as degradable materials to obtain a mulch film with a slow-release fertilizer function (MSRF). MSRF had excellent performance when 10% AL was added. The properties consisted of elongation at break (180.14%), water vapor permeability (203.8 g m–2 day–1), water resistance (its morphology remained good for 50 days), water absorption (300%), and urea release efficiency (cumulative release of 70.63% in 30 days). Rapid plant growth trials demonstrated that the MSRF had excellent functionality and that the MSRF could reduce the amount of fertilizer applied by about 70%. These excellent performances were due to the combination of chemical cross-linking (chemical bonding) between AL and PVA/CS molecular chains, the hydrogen bonding between the AL, PVA, and CS molecules, and the aggregation properties of AL. This provided a green and efficient strategy for the preparation and application of dual functions of mulching and the slow release of fertilizer.

“…Superabsorbent polymers (SAPs) are a subset of water‐absorbent polymers that can retain water (or aqueous solutions) of 10–1000 g/g. [ 1 ] Recently, SAPs have received significant attention from researchers due to their various applications [ 2 ] in the fields of hygiene, [ 3 ] healthcare, [ 2–6 ] agriculture, [ 7–27 ] and construction.

“…In agricultural applications, [15,19] SAPs can retain and slowly release water, allowing them to improve water irrigation and amend (moisturize) dry soils. [32] Furthermore, SAPs create improved growing conditions for vegetation by reinforcing available water, thereby increasing the transport of nutrients [7] from soils to plants.…”

Performance of a novel, eco‐friendly, cellulose‐based superabsorbent polymer (Cellulo‐SAP): Absorbency, stability, reusability, and biodegradability

Superabsorbent polymers (SAPs) have attracted tremendous attention recently, with researchers noting that their high water absorbability is valuable for various applications, especially in agricultural contexts. Two types of materials can be used to produce SAPs: Fossil-based (which are harmful to the environment) and bio-based (which are significantly more environmentally friendly, given their biodegradability and minimal toxic side effects). Although bio-based SAPs are preferable for environmental reasons, their synthesis tends to be time consuming and labour intensive, while their absorption capacity (AC) can be far below expectations. To address these problems, a novel, eco-friendly, cellulose-based superabsorbent polymer (Cellulo-SAP) was developed in this study through facile preparation via free radical synthesis using modified cellulose. Then, the absorbency, thermal/pH stability, reusability, and biodegradability of Cellulo-SAP were evaluated. This new polymer demonstrated reusability as a water reservoir, in addition to high thermal and pH stability.More importantly, Cellulo-SAP achieved an AC of 475 g/g and exhibited superior biodegradability compared to a commercial, fossil-based SAP. Accordingly, these results prove that Cellulo-SAP can be used in agriculture as an effective alternative to fossil-based SAPs.
