Introduction: Composting is one of the effective environmental protection and sustainable measures for improving soil quality and increasing crop yield. However, due to the special physical and chemical properties of saline-sodic soil and the complex rhizosphere microecological environment, the potential mechanism of regulating plant growth after applying compost in saline-sodic soil remains elusive.
Methods: Here, we investigated the effects of different compost addition rates (0, 5, 15, 25%) on plant growth traits, soil chemical properties, and rhizosphere bacterial community structure.
Article Synopsis
- Soil salinization poses a significant threat to agriculture, but compost application can help reclaim saline-sodic soils by enhancing soil properties and plant health.
- Compost significantly boosts soil nutrients and enzyme activities, leading to improved leaf photosynthesis and ion balance in alfalfa plants.
- The study also found that compost alters rhizosphere fungal communities by decreasing pathogenic fungi and changing community diversity, highlighting its potential for improving plant resilience against saline stress.
Home courtyard agriculture is an important model of agricultural production on the Tibetan plateau. Because of the sensitive and fragile plateau environment, it needs to have optimal performance characteristics, including high sustainability, low environmental pressure, and high economic benefit. Emergy analysis is a promising tool for evaluation of the environmental-economic performance of these production systems.
