Special Issue Information

Dear Colleagues,

The intensive use of inorganic fertilizers in horticultural production has contributed to high yields but has also raised serious concerns related to environmental degradation, soil health decline, and food safety. In the context of climate change and increasing pressure on natural resources, sustainable fertilization strategies are becoming essential.

Organic fertilizers and biofertilizers represent promising alternatives for reducing dependency on synthetic inputs. Materials such as compost, manure, slurry, liquid manure, earthworm compost, peat, and green manure improve soil structure, nutrient cycling, and biological activity. In parallel, biofertilizers based on beneficial microorganisms enhance nutrient availability, stimulate plant growth, and support plant resilience to biotic and abiotic stresses.

The application of organic and biological fertilizers influences soil–plant–water interactions and contributes to improved crop quality while maintaining ecological balance. Advances in biotechnology and sustainable agronomic practices enable more efficient formulation and application of these inputs under open-field and protected horticultural systems.

This Special Issue, titled “Sustainable Horticultural Production: Applications of Organic Fertilization and Biofertilizers in Horticultural Cultivation”, welcomes original research articles and reviews addressing innovative approaches, mechanisms, and practical outcomes of organic and biofertilizer use in horticultural crops. Studies focusing on soil health, plant nutrition, yield quality, and environmental sustainability are particularly encouraged.

We look forward to receiving your contributions.

Continuous cultivation in solar greenhouses degrades black soil, leading to soil-borne diseases, nutrient imbalances, reduced porosity, and microbial dysbiosis, all of which collectively decrease crop productivity. Improving soil structure and microbial balance often requires costly amendments that are inconsistent in their effectiveness. This study evaluated two low-cost soil amendments—carbonized rice hull (CRH) and fermented rice hull (FRH)—using colored pepper as a model crop. Treatments included soil mixed with 30% CRH (T1), 30% FRH (T2), and untreated black soil (CK). Both amendments significantly improved soil physical properties. Compared with CK, soil porosity increased by 8.80% in T1 and 17.84% in T2, while water-holding capacity increased by 75.32% and 133.45%, respectively. Soil microbial richness, as indicated by Abundance-based Coverage Estimator (ACE) and Chao indices, followed the order T2 > T1 > CK. Plant physiological performance was also enhanced. Net photosynthetic rate increased by 7.18% (T1) and 15.33% (T2), plant height increased by 14.42% (T1) and 28.85% (T2), and root activity improved significantly. Fruit weight increased by 15.33% in T1 and 21.62% in T2. Both rice hull amendments improved soil quality and promoted crop growth, with FRH performing consistently better. These findings indicate that fermented rice hull is a promising, low-cost strategy for greenhouse soil remediation. Full article

Due to the environmental impact and increasing cost of inorganic fertilizers, farmers are exploring alternative fertilization strategies. Tenebrio molitor, otherwise known as the mealworm, is one of the most widely reared insect species for the production of high-quality protein for animals and humans. Mealworm frass (MF), a nutrient-rich byproduct of Tenebrio molitor cultivation, presents a viable option for organic fertilization. To investigate the fertilizer potential of frass, a greenhouse pot experiment was conducted, comparing three levels of MF (MF1, MF2, and MF3 at 20, 40, and 80 g/L soil, respectively), organic compost (ORG), and inorganic fertilizer (FERT). MF gave comparable results to FERT in terms of the measured parameters of vegetation, flowering, and production. ORG also gave comparable results to FERT as far as flowering and production but had significantly lower height compared to it. The MF3 treatment significantly improved the average fruit weight and total yield by 19.56% and 30.81%, respectively, compared to the ORG treatment. The two highest doses of MF outperformed FERT in terms of leaf and soil nutrient status, while MF1 and ORG did not differ from it. Furthermore, MF3 yielded 20% greater fruit weight than MF1. However, MF1 was comparable to FERT in fruit weight, resulting in superior fruit color. These results support reduced-input agriculture by providing data for optimizing soil fertility and nutrient management in crops. The findings of this experiment suggest that MF is a viable alternative to inorganic fertilizers and organic compost for greenhouse cultivation of tomatoes. These results highlight the potential of MF as a circular, bio-based fertilizer capable of maintaining tomato productivity while improving soil fertility under protected cultivation systems.
