continuous-cropping
Continuous cropping refers to the repeated cultivation of the same plant species on the same plot of land over successive growing seasons without rotation. This practice often leads to obstacles known as continuous cropping obstacles, including soil nutrient imbalance, buildup of soil-borne pathogens, and autotoxicity from accumulated root exudates, which can significantly reduce plant growth and yield. Understanding these effects is crucial for developing sustainable agricultural strategies and improving soil-plant-microbe interactions in intensive farming systems.

Irrigating crow-dipper (a traditional medicinal herb) with ozone-treated water improved plant growth by up to 30% and diversified beneficial soil bacteria, offering a practical fix for the yield losses that come from planting the same crop in the same soil year after year. Fumigating the tubers directly with ozone gas produced the opposite effect, reducing chlorophyll and highlighting how much delivery method matters.
Ozonated water irrigation increased germination rate, plant height, and tuber fresh weight by 10-30% compared to untreated controls
Ozonated water irrigation produced the highest bacterial diversity (Chao1 and Faith indices) and enriched beneficial genera including PSRF01 and Sphingomicrobium
Direct ozone fumigation of tubers reduced leaf chlorophyll content by 10-30%, showing that application method critically determines whether ozone helps or harms the plant
