Fixing salty soil takes better soil, tougher crops, and helpful microbes together

Soil Health
If your garden beds have white crusty residue, stunted seedlings, or leaf edges that brown after watering with hard water, you're seeing the same salt stress this review says is spreading across farmland worldwide, and the fixes it covers, like gypsum, organic matter, and salt-tolerant plants, apply at backyard scale too.
Too much salt in soil stops plants from drinking water and poisons their cells, and huge areas of farmland are affected. Scientists are attacking the problem from several sides: improving the soil itself, using helpful microbes and salt-loving plants to clean it up, and breeding crops that handle salt better. The catch is that most of these tricks work in lab seedlings and still need proof in real fields.
Key Findings
Soil salinization affects roughly 8.31 × 10^8 hectares of soil resources globally, making it a major threat to food security.
Salt and alkali tolerance in plants relies on ion transporters that keep salt balanced inside cells, cross-talk among hormones such as ABA, JA, and GA, and epigenetic regulation.
A large gap remains between lab seedling studies and field yield gains; the authors recommend field-based yield validation, combining CRISPR/Cas genome editing with microbiome engineering, and weighing the socioeconomic feasibility of large-scale remediation.

Salty and alkaline soils cover about 831 million hectares worldwide and threaten food production. This review pulls together soil fixes, helpful microbes, salt-tolerant plants, and gene editing, and says the next step is proving they raise yields in real fields, not just in seedling tests.

Phytoremediation uses living plants to clean up soil, air, and water contaminated with hazardous substances. This approach is significant for plant science because it demonstrates plants' remarkable ability to absorb and metabolize pollutants, revealing key mechanisms of plant physiology and
