Published: Jan. 15, 2024

Soil salinity is a serious problem facing many countries globally, especially those with semi-arid and arid climates. can have negative influences on soil microbial activity as well chemical physical processes, all of which are crucial for health, fertility, productivity. negatively affect physiological, biochemical, genetic attributes cultivated plants well. Plants wide variety responses to stress classified sensitive (e.g., carrot strawberry), moderately (grapevine), tolerant (wheat) (barley date palm) depending the salt content required cause crop production problems. Salinity mitigation represents critical global agricultural issue. This review highlights properties classification salt-affected soils, plant damage from osmotic due salinity, possible approaches (i.e., applied nutrients, inoculations, organic amendments, physio-chemical approaches, biological nano-management), research gaps that important future food security. The strong relationship between different subdisciplines (mainly, biogeochemistry, microbiology, fertility nutrition) also discussed.

Saline–Alkali Soil Reclamation Contributes to Soil Health Improvement in China

Agriculture, Journal Year: 2024, Volume and Issue: 14(8), P. 1210 - 1210

Published: July 23, 2024

Soil salinization is a significant threat to soil health, especially the agricultural ecosystem; it reduces vegetation biomass, destroys ecosystem diversity, and limits land use efficiency. This area of investigation has garnered extensive attention in China, arid semi-arid areas, totaling 7.66 × 106 ha. A variety theoretical research technology developments have contributed water salt regulation screening salt-tolerant varieties improve nutrient utilization efficiency microbial control reduce ecological problems due saline-based obstacles. These techniques can be classified into physical treatments, chemical biological combined treatments; these different measures are all aimed at primarily solving saline–alkali stress. In general, improvement contribute health improvement, concentrating on high-quality development, food security, cultivated protection, upgrading. However, risks various technologies practical production process should highlighted; green healthy still expected applied land.

Building microbial consortia to enhance straw degradation, phosphorus solubilization, and soil fertility for rice growth

Microbial Cell Factories, Journal Year: 2024, Volume and Issue: 23(1)

Published: Aug. 21, 2024

Straw pollution and the increasing scarcity of phosphorus resources in many regions China have had severe impacts on growing conditions for crop plants. Using microbial methods to enhance straw decomposition rate utilization offers effective solutions address these problems. In this study, a consortium 6 + 1 (consisting straw-degrading bacterium phosphate-solubilizing bacterium) was formulated based their performance degradation solubilization. The by reached 48.3% within 7 days (The ability 7% higher than that single bacteria), dissolution insoluble 117.54 mg·L− solubilization 29.81% bacteria). addition, activity lignocellulosic degrading enzyme system significantly increased, activities endoglucanase, β-glucosidase xylanase were those strain (23.16%, 28.02% 28.86%, respectively). Then processed into agents tested rice pots. results showed agent increased content organic matter, available nitrogen soil. Ongoing research focuses determination effects mechanisms functional hybrid removal. characteristics two strains are as follows: Straw-degrading bacteria can efficiently degrade produce glucose-based carbon sources when only is used source. Phosphate-solubilizing use glucose source, acids dissolve consume at an extremely fast rate. analysis suggests outperformed individual terms both application effects. promote each other during growth processes, resulting source consumption compared isolation. This demand facilitates strains. At same time, substantial metabolic process generated large number acids, leading phosphorus. It also provides basis construction type consortium.

Sampling campaigns were conducted summer winter. results show salts exhibited greater differences time than space there higher pollution levels winter summer. During summer, abundant non-point source from rainfall input provided rich substrate for bacteria water, leading strong competitiveness PAOs nitrifying bacteria. Meanwhile, high temperature was favorable exchange elements at SWI, release P, Fe, N, while, low temperatures DO seen winter, SOB denitrifying active, which correctly indicated concentration SO42− NH4+-N water. microbial diversity abundance also affected by season, richness communities salinity salt had significant inhibitory effect microorganisms.
