The maturation of biobased polymer synthesis process has led to the rapid adoption controlled-release fertilizers (BCRFs).

Wood distillate (WD), also known as pyroligneous acid, is a liquid byproduct of charcoal production. It has antimicrobial and antifungal properties thanks to its combination over 200 components, including organic acids, polyphenols, tannins others. In this work, microcapsules containing WD coated with chitosan or micronized biochar were developed, their efficacy was tested against the soil-borne fungal pathogen Macrophomina phaseolina. The three products used fit into circular economy model, these bio-based can be promote sustainable agricultural practices. microencapsulation carried out via an ion-exchange gelation method, using sodium alginate polymer. coating formation successfully performed, resulting in size between 600 700 µm when dried. Three types produced: uncoated, chitosan-coated chitosan–biochar-coated. Solubility tests conducted by measuring pH each type microcapsule distilled water. observed that solubilization trends different depending on microcapsules. vitro growth M. phaseolina PDA plates completely inhibited concentrations 3–5%. Furthermore, added culture medium, those induced significant reduction growth.

Carboxymethyl cellulose sodium salt (CMC)-based superabsorbents are promising materials for the development of agricultural matrices aimed at water management and slow-release fertilizer production. However, an increase in CMC content tends to reduce their water-absorbing capacity. This study aims develop a cost-effective method producing eco-friendly with enhanced capacity by incorporating porogen employing lyophilization. Superabsorbents containing 10 wt% (CMC-SAPs) were synthesized via free radical polymerization addition 0, 5, or ammonium carbonate as porogen, followed The CMC-SAPs characterized using Fourier-transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis, differential calorimetry, X-ray diffraction. results revealed that prepared incorporation and/or subjected lyophilization exhibited well-developed surfaces featuring macropores cavities. Incorporating 5 lyophilization, increased equilibrium swelling ratio 61%. improvement was attributed surface morphology modified CMC-SAPs, which facilitated molecule diffusion into SAP matrix, confirmed open porosity measurements. hypothesis further supported coefficient values, higher porogen-containing lyophilized SAPs compared unmodified samples. Moreover, demonstrated good reusability. Thus, combination subsequent represents approach enhancing uptake CMC-based composite sustainable applications.
