“…Previous studies have demonstrated that biogas digestate application led to a higher soil nitrification rate than manure [7,8] and compost [9]. Thus, the use of biogas digestate may increase nitrate leaching risks [10][11][12][13][14], as reported in our previous study [15] where biogas digestate increased nitrate contents in soil through a stimulatory effect on nitrification.…”

This study investigated the effects of biogas digestate application to soil with rice straw on nitrate leaching potential and nematicidal activity toward root-knot nematodes Meloidogyne incognita. The following seven treatments were set up: (i) control (CONT); (ii) chemical fertilizer (CF); (iii) wet biogas digestate derived from pig manure (WBD); (iv) and (v) dry biogas digestate derived from a mixture of pig manure and rice straw at an initial C/N ratio of 20 and 30 (DBD20 and DBD30); (vi) and (vii) DBD20 mixed with rice straw to adjust the C/N ratio to 16 (Mix1) and 30 (Mix2), respectively. The application rate of CF and digestates was adjusted to 200 mg N kg−1 soil based on the inorganic ammonium nitrogen contents. Nitrate contents readily increased in all the treatments with incubation, except for Mix2, and those at day 90 were decreased with increasing initial labile C contents. Garden balsam was grown as a test plant for root-knot nematodes using the soils at day 90 and the results showed that the gall index was significantly lower in Mix2 and Mix1 than in CF. These results suggest that dry digestate mixed with rice straw might have potential for lower nitrate leaching and nematicidal properties.

“…In another experiment, vermicompost signi cantly increased strawberry growth and yield including 37% increase in the leaf areas, 37% increase in green plant biomass, 40% elevation in the number of owers, 36% increase in the number of runners, and 35% elevation in weight of marketable fruits [10]. When 25% vermicompost was added to the fertilizer, the strawberries grown in the greenhouse at 18 weeks showed the maximum vegetative biomass compared to using fertilizer individually [14]. In an experiment the total chlorophyll content in the two treatments of 10 and 20% vermicompost, increased compared to the control [34].…”

Background: Consecutive droughts and quantitative and qualitative reduction of surface and underground water resources have caused an increase in greenhouse and hydroponic cultivation for most garden crops, including strawberries, in Iran. On the other hand, most of the inputs of greenhouse crops in Iran are imported. To possibility of replacing vermicompostwith peat moss under hydroponic cultivation, an experiment was done in a split plot based on randomized complete blocks design in three replications in Isfahan (Iran) Agricultural and Natural Resources Research Center in 2019. The main treatment was substrate at four levels included different levels of vermicompost (30 and 50%) and peat moss (30 and 50%) in combination with perlite and sub-treatment were Selva and Camarosa cultivars. Results: The results showed that Camarosa in 50% perlite/ 50% peat moss and Selva in 50% perlite / 50% peat moss and 70% perlite /30% vermicompost had maximum yield. Leaf number, chlorophyll index were the highest in Camarosa cultivar in peat moss substrates. Strawberry cultivars had the highest amount of root fresh weight, vitamin Cand soluble solids in substrates containing vermicompost. Camarosa in 50% perlite/ 50% peat moss and Selva in 50% perlite /50% vermicompost had maximumroot dry weight. Also The highest number of inflorescences was related to substrates containing peat moss and 70% perlite / 30% vermicompost. Maximum amount of fresh and dry weight of shoots were observed in 70% perlite/30% peat moss. Selva cultivar had more inflorescences (16.5%) than Camarosa and Camarosa cultivar produced more fresh and dry weight of shoots (16.5%, 23.01%) than Selva. Conclusion:Both strawberry cultivars in vermicompost and peat moss beds were slightly different from each other, even in traits such as TSS, vitamin C, and root fresh weight, vermicompost was better than peat moss, so since vermicompost is more cost-effective and affordable compared to peat moss, so a slight reduction in some traits in vermicompost in comparison with peat moss, it is justified and can be recommended as an alternative to peat moss in Selva and Camarosacultivar.
