The rapid growth of the horticultural industry has increased demand for soilless cultivation substrates. Peat, valued its physical and chemical properties, is widely used in cultivation. However, peat non-renewable, over-extraction poses serious ecological risks. Therefore, sustainable alternatives are urgently needed. Ammonium incubation, a novel method to reduce phytotoxicity, offers potential green waste, significant organic solid waste resource, substitute peat. This study optimized ammonium incubation process phytotoxicity. It systematically examined different nitrogen salts (type amount) environmental conditions (temperature, aeration, duration) affecting detoxification efficiency. Results show reduction phytotoxicity with bicarbonate, carbonate, sulfate, especially at 1.5%. Optimal were 30 °C 5 days regular aeration. Under these conditions, salt-treated significantly reduced total phenolic content stabilized germination index (GI) non-phytotoxic level (127%). Using treated as partial lettuce showed promising results. low-cost, low-energy effectively converts into alternatives, promoting eco-friendly horticulture conservation.

The depollution of constructed wetland-pretreated olive mill wastewater (OMW) using a membrane filtration system was experimentally studied. Dead-end (DEF) employed to evaluate suitable MF/UF membranes and select the appropriate molecular weight cut-off for optimal OMW treatment. Removal efficiencies COD (chemical oxygen demand) TOC (total organic carbon) DEF reached maximum values 88.14% 11.17%, respectively. Adsorption raw pretreated on granular activated carbon also carried out comparative study against pretreatment. semi-industrial-scale experiments were conducted commercial ceramic ultrafiltration (UF) (150 50 kDa) in cross-flow (CFF) mode at permeate flux around 200 L h−1 m−2 trans-membrane pressure (TMP) 3.5–3.8 bars. This post-treatment had significant impact removal efficiency from OMW, reaching 78.5%. coupled process proposed this achieved 97%, 99.9% COD, TOC, turbidity,

Substrate is the key material of soilless culture. The physical and chemical properties solidified cultivation medium are good relatively stable, there no need to use plastic containers in process, which has a broad application prospect three-dimensional greening fruit vegetable planting. We have developed novel substrate process with high-frequency electromagnetic heating, significantly reduces energy consumption compared traditional curing steam heating. In this study, effects three modification methods (alkali modification, APTES alkali + combined modification) on physicochemical jute were studied, strengthening different modified fibers solidification investigated. results showed that addition fiber could improve mechanical substrate. Compared control group, increase breaking tension by 13.1~24.2 N, impact toughness 0.85~2.09 KJ/m2, hardness 21.6~35.6 HA. Moreover, small amount can effectively will not affect growth plant roots.

This study investigated the phytotoxicity of agro-industrial wastes (almond, walnut, pistachio and peanut shells, asparagus spears, brewer’s spent grain) their biochar through germination bioassays in several horticultural species: green pea, lettuce, radish, arugula. Biowaste was pyrolyzed under controlled conditions to produce biochar, both biowaste were characterized. Germination bioassay conducted using seeds exposed different dilutions aqueous extract (0, 50, 100%). percentage, seed vigor, index, root aerial lengths evaluated. The results showed that significantly its biochar. obtained demonstrated changing effects on seedling growth. In particular, extracts from brewers grains, walnut shells 5–14% increases vigor length. Furthermore, response species waste revealed species-specific sensitivity. Seeds lettuce arugula more sensitive than radish peas. knowledge not only elucidates behavior waste-based early stage plant development but also provides valuable insights regarding phytotoxicity, sensitivity, variables involved germination.
