In a groundbreaking study published in ‘مدیریت خاک و تولید پایدار’ (Soil Management and Sustainable Production), researchers have uncovered a promising solution to combat soil salinity, a major challenge for agricultural productivity, particularly in rice cultivation. The research led by ساره رجبی اگره, a PhD graduate from the Department of Soil Science at the University of Agricultural Sciences and Natural Resources in Gorgan, focuses on the effects of specific strains of Pseudomonas fluorescens on nutrient concentrations in rice plants under saline conditions.
Salinity in soil and irrigation water not only hampers plant growth but also leads to nutrient imbalances that can severely affect crop yields. The study employed a factorial experiment to assess how different strains of Pseudomonas bacteria could enhance the resilience of rice plants to saline stress. The findings are significant: as salinity levels increased, the concentrations of essential micronutrients like manganese, iron, zinc, and copper in both the leaves and grains of rice decreased markedly. However, inoculating rice seeds with various strains of Pseudomonas fluorescens and Pseudomonas putida resulted in a substantial increase in these nutrient levels compared to untreated controls.
“By applying these beneficial bacteria, we observed a noticeable enhancement in nutrient uptake, which is crucial for maintaining plant health under stressful conditions,” رجبی اگره noted. This could be a game-changer for farmers dealing with saline soils, especially in regions where traditional farming practices are becoming less viable.
The practical implications of this research extend beyond agriculture. The construction sector, particularly in regions prone to soil salinity, may find this study relevant as it highlights the importance of sustainable agricultural practices in maintaining soil health. Healthy soils are not just vital for farming; they also underpin the stability of construction projects. Saline soils can lead to structural issues, and understanding how to mitigate their effects could inform better land management practices for future developments.
Moreover, the application of biostimulants like Pseudomonas could pave the way for eco-friendly construction materials. As the demand for sustainable construction rises, integrating agricultural innovations could lead to the development of bio-based materials that enhance soil quality while reducing environmental impact.
As the agricultural sector grapples with the challenges posed by climate change and soil degradation, strategies that improve crop resilience will be paramount. The research by رجبی اگره and her team not only offers a scientific pathway to enhance rice productivity but also opens doors for interdisciplinary collaboration between agriculture and construction, fostering a more sustainable future.
