Uzbekistan faces a convergence of soil salinisation, declining organic matter, waterbody sedimentation, and industrial contamination that directly threatens agricultural sustainability. This study presents an integrated soil\u2013water\u2013biotechnology framework that links ecological restoration of waterbodies with soil fertility recovery through biologically activated sediments, microbial consortia, biosurfactants, mineral\u2013organic carriers, and phytoremediation crops.<\/p>\n\n

The framework builds upon AVELIFE comprehensive solutions for sustainable agriculture in Uzbekistan, which emphasize soil fertility restoration, stress-resistant crops, prolonged nutrient release, detoxification of soils, and active silicon as a structural and biological carrier.<\/span> \n \n \n<\/span>Experimental evidence from long-term bioremediation trials demonstrates that combined application of hydrocarbon-degrading microorganisms, rhamnolipid biosurfactants, calcium peroxide, and plants reduced oil contamination from 9.5% to 1.3\u20131.6%, increased soil dehydrogenase activity up to 2.7-fold, and decreased soil phytotoxicity more than 3.5 times.<\/span><\/p>\n\n

The proposed model establishes a circular soil\u2013water regeneration loop suitable for Uzbekistan\u2019s arid agroecosystems and provides a scalable pathway for climate-resilient agriculture, land reclamation, and desert greening.<\/p>\n\n

1. Introduction<\/h3>\n\n

Uzbekistan\u2019s agricultural sector operates under conditions of water scarcity, salinity stress, and long-term soil degradation. Large irrigation systems, intensive cotton and cereal production, and sediment accumulation in canals and reservoirs have created a coupled crisis of declining water quality and soil fertility.<\/p>\n\n

Conventional reclamation practices focus primarily on chemical amendments and physical dredging. However, these approaches rarely address biological soil health, which is fundamental for long-term productivity.<\/p>\n\n

Recent advances in environmental biotechnology demonstrate that soil biological activation\u2014through microorganisms, biosurfactants, and plants\u2014can restore degraded soils at significantly lower cost and environmental impact than physicochemical treatments.<\/p>\n\n

2. Conceptual framework: coupling water restoration and soil regeneration<\/h3>\n\n

The proposed framework integrates two traditionally separate domains:<\/p>\n\n

    \n
  1. Ecological restoration of waterbodies and irrigation infrastructure.<\/li>\n\n\n\n
  2. Biological recovery of soils using activated sediments and AVELIFE biotechnologies.<\/span><\/li>\n<\/ol>\n\n

    Dredged bottom sediments, after ecological screening and biological activation, become carriers of organic matter, silicon, and nutrients, forming soil-improving substrates rather than waste.<\/p>\n\n
