Special Issue Information

Dear Colleagues,

With the intensification of agro-industrial practices, both crop quality and quantity have declined steadily, as has overall soil health. Therefore, the adoption of sustainable agricultural practices has become essential if these challenges are to be addressed and long-term productivity ensured.

The recycling or reuse of various organic wastes to produce soil amendments, organic fertilizers, biostimulants, or biocontrol agents has been an actively researched area of this field and promises to offer viable alternatives to existing synthetic analogues, ultimately supporting environmental health.

Given that organic waste management remains a critical global concern, this Special Issue aims to explore innovative strategies for the agronomic utilization of organic waste materials from diverse sources to support the development of circular agricultural systems. Authors are welcomed to submit their most recent research findings or comprehensive reviews addressing, but not limited to, the following topics:

  • Effects of organic waste application on soil fertility, plant growth, crop quality, and soil microbial communities;
  • Development and application of biofertilizers, biostimulants, and biocontrol agents derived from organic wastes and by-products;
  • Environmental implications and sustainability assessments related to organic waste utilization in agro-industry;
  • Advances in the reuse of organic wastes as soil amendments or plant protection agents.

Compost-derived products are increasingly used to enhance soil biological activity and plant performance in perennial fruit systems, but the effects of compost tea (CT) in kiwifruit orchards remain unexplored. This study assessed root-zone applications of aerated CT from 2023 to 2025 on the yield and fruit quality of gold kiwifruit in a commercial pergola-trained orchard. Two treatments were compared: weekly CT fertigation during summer and an untreated control (Ctrl). Yield, fruit number, mean fruit weight, and fruit quality—hue angle (H°), firmness, soluble solids content (SSC), and dry matter were evaluated annually. The CT application did not significantly affect total yield or fruit number over three seasons. However, it increased the mean fruit weight and shifted fruit distribution toward larger size classes. Fruit quality responses varied: CT-treated fruits initially showed lower firmness and SSC, but in the final year, firmness and SSC matched controls. Dry matter content was higher in CT fruits (18.87%) than in controls (16.71%). These results indicate that during the early to mid-bearing phase, CT promotes fruit growth toward larger sizes and enhances dry matter accumulation. Gradual benefits appeared after three annual applications, suggesting CT is a promising tool for medium- to long-term soil and rhizosphere management in kiwifruit. Full article
