Abstract Peat is an unrenewable resource. The potential of using composts made from a mixture agricultural and agro-industrial wastes as peat substitutes was evaluated in this study. Four compost piles (C1-C4) were constructed by mixing various after estimating their properties. C1 1:1:1.5 weight ratio filter mud, mushroom waste, date-palm fronds, while C2-C4 0.5:1 between either bagasse, cutting grassland, or fronds cattle dung. After four months decomposition, the compost’s physical, chemical, biological properties estimated comparison to commercial (CC), peatmoss (PM), ideal ranges (IR) for seed germination seedling growth.

The aim of the current study was to create a high quality growing medium blend that replaces 70 vol% peat with 40 woody green compost and 30 bark organic fertilizers (i.e., blood meal chitin), all locally sourced. A range “woody composts”, i.e., composts based on feedstock selection mainly material from tree prunings, were produced for this purpose at facilities. First, characterized chemically biologically, including their microbial biomass net N release. In comparison regular or vegetable, fruit garden (VFG) waste composts, are more suitable use in media due lower pH, EC inorganic C content; however, had low mineralization rate. Three types supported higher than wood fiber compost. additional mineral release after 100 days mixed tested different VFG composts. significantly measured initial concentrations (317 mg Nmin/L) as well (417 concentration (148 Nmin/L). last step, compost, fiber, coir ratios, resulting six blends ranging 100% peat-free peat. Two batches compared, chitin. strong effect both fertilizer composition observed, clear link between There significant negative correlation change (R = −0.85), which implies larger increase during incubation resulted less mineralization. containing scored better nitrification activity, NH4-N these without For blends, no observed addition fertilizers; did increase, however.

Abstract This study explores the potential of nitrogen-enriched lignins produced via ammoxidation – a process combining oxidation and nitrogen incorporation with ammonia (NH 3 ) oxygen (O 2 to improve wood fibres as sustainable peat alternatives in horticultural substrates. Organocell lignin (OCL) kraft (KL) were assessed, focusing on effect conditions total amide using OCL reference. Total content KL (NKL) reached 6.3 % under 60 bar pressure, but remained low (0.64 %), indicating challenges optimizing this type.

Adding 10 NOCL improved peat-free substrates, though less effectively than concentration. Conversely, NKL had no notable wood-fibre negatively affected The results underscore importance modifying reactivity prior boost incorporation, offering insights into viability substitutes horticulture.
