The key lies in adopting a regenerative approach with quality <a href=\"https:\/\/www.quelagrow.com\/en\/bioprotectors\/soil-disinfectants\/\">soil disinfectants<\/a>. The main idea: <strong>disinfect selectively and subsequently regenerate the microbiota<\/strong>. In this article, we explore sustainable disinfection methods and how <a href=\"https:\/\/www.quelagrow.com\/en\/bioprotectors\/\">bioprotectant<\/a> products like <strong>DIVENHO<\/strong> and <strong>QUEMOXYGEN<\/strong> can be strategic allies in this process, helping you achieve healthy, productive, and balanced soil.<\/p>\n<h2>Importance of disinfecting agricultural soil and its main benefits<\/h2>\n<p>The main goal of disinfection is to reduce or eliminate the load of pathogens living in the soil that reduce crop productivity. Carrying out effective disinfection, especially with sustainable methods, provides decisive advantages:<\/p>\n<ul>\n<li><strong>Reduction of harmful pathogens:<\/strong> Eliminates or drastically reduces the population of fungi, bacteria, and plant-parasitic nematodes that cause major root diseases.<\/li>\n<li><strong>Weed control:<\/strong> Reduces the weed seed bank in the soil, decreasing competition for nutrients and water.<\/li>\n<li><strong>Improved production and initial health:<\/strong> Allows a clean, healthy start for the new crop, with more vigorous plants and less need for later interventions.<\/li>\n<li><strong>Long-term sustainability:<\/strong> Methods like solarization and biofumigation are environmentally friendly as they do not use aggressive synthetic chemical agents.<\/li>\n<\/ul>\n<p>To maximize effectiveness, it is vital to carry out a prior <strong>phytopathological analysis<\/strong> to determine the most appropriate control method based on the specific pathogens present in your soil.<\/p>\n<h2>Traditional soil disinfection vs. Regenerative approach: The problem of the &#8220;biological vacuum&#8221;<\/h2>\n<p>Conventional chemical methods (such as dazomet or metam sodium) act like a &#8220;bomb&#8221; in the soil: they eliminate practically all life, both harmful and beneficial. This creates a <strong>biological vacuum<\/strong> that is often recolonized first by the most aggressive pathogens or residual flora, generating a <strong>regrowth effect<\/strong> that worsens the problem in the medium term. Furthermore, they leave residues and can be harmful to the applicator and the environment.<\/p>\n<p>The regenerative approach seeks a balance: <strong>to disinfect selectively or create hostile conditions for pathogens, while preserving or quickly recovering the beneficial microbiota<\/strong>. This is where sustainable methods and bioprotectants shine.<br \/>\n<img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone wp-image-8115 size-full\" src=\"https:\/\/www.quelagrow.com\/wp-content\/uploads\/biocontrol-desinfectar-suelo-agricola-1.jpg\" alt=\"agricultor pulverizando desinfectantes de suelo\" width=\"1376\" height=\"768\" srcset=\"https:\/\/www.quelagrow.com\/wp-content\/uploads\/biocontrol-desinfectar-suelo-agricola-1.jpg 1376w, https:\/\/www.quelagrow.com\/wp-content\/uploads\/biocontrol-desinfectar-suelo-agricola-1-300x167.jpg 300w, https:\/\/www.quelagrow.com\/wp-content\/uploads\/biocontrol-desinfectar-suelo-agricola-1-1024x572.jpg 1024w, https:\/\/www.quelagrow.com\/wp-content\/uploads\/biocontrol-desinfectar-suelo-agricola-1-768x429.jpg 768w, https:\/\/www.quelagrow.com\/wp-content\/uploads\/biocontrol-desinfectar-suelo-agricola-1-1000x558.jpg 1000w\" sizes=\"(max-width: 1376px) 100vw, 1376px\" \/><\/p>\n<h2>Sustainable methods for disinfection that respects the microbiota<\/h2>\n<p>There are effective techniques that minimize environmental impact and the indiscriminate destruction of soil life. The main methods include:<\/p>\n<h3>1. Solarization: The power of the sun as a disinfectant<\/h3>\n<p>This is a passive technique that consists of covering moist soil with transparent plastic during the hottest months (generally from June to August). The heat accumulated by solar radiation (reaching lethal temperatures &gt;40\u00b0C) eliminates a wide range of pathogens, insects, and weed seeds.<\/p>\n<p><strong>Steps for effective solarization:<\/strong><\/p>\n<ol>\n<li><strong>Cleaning<\/strong>: Remove all residues from the previous crop.<\/li>\n<li><strong>Preparation<\/strong>: Plow or till the soil to aerate it and break up clods.<\/li>\n<li><strong>Irrigation<\/strong>: <strong>Saturate the soil with water<\/strong>. Moisture is crucial, as water conducts heat up to 500 times better than air.<\/li>\n<li><strong>Coverage<\/strong>: Cover with transparent plastic of adequate thickness (generally 50-75 microns), ensuring an <strong>airtight seal at the edges<\/strong> with soil to prevent heat and gas leakage.<\/li>\n<li><strong>Time<\/strong>: Keep the soil covered for a period of <strong>4 to 6 weeks<\/strong>.<\/li>\n<\/ol>\n<h3>2. Biofumigation: Disinfection with organic matter<\/h3>\n<p>This technique involves incorporating fresh organic matter (such as animal manure or crop residues, especially from the <strong>Brassicaceae<\/strong> family: mustard, radish, rapeseed) into the soil. As this matter decomposes, it releases gases such as <strong>isothiocyanates<\/strong> (from crucifers) and ammonia, which have a powerful natural fungicidal and nematicidal effect. It is a method that can be applied at any time of the year, although decomposition is faster with heat.<\/p>\n<h3>3. Biosolarization: The winning combination<\/h3>\n<p><strong>Biosolarization<\/strong> combines the two previous techniques. Organic matter is incorporated (biofumigation) and then the soil is covered with plastic (solarization). This synergy is very powerful, as the gases generated are trapped under the sheeting and the heat accelerates their action and the decomposition of organic matter, achieving the best results in pathogen control.<\/p>\n<h2>Boosting sustainable disinfection: The role of DIVENHO and QUEMOXYGEN<\/h2>\n<p>To make solarization or biosolarization even more effective, especially in heavily damaged soils or those with persistent pathogens, we can rely on specific bioprotectants.<\/p>\n<h3>QUEMOXYGEN<\/h3>\n<p>Its ability to release active oxygen in the aqueous medium makes it an excellent ally in the <strong>soil saturation<\/strong> phase prior to solarization. It improves irrigation water quality, reduces the load of unwanted microorganisms in the soil solution, and oxygenates the medium, creating less favorable conditions for anaerobic pathogens even before sealing.<\/p>\n<p><a href=\"https:\/\/www.quelagrow.com\/en\/bioprotectors\/soil-disinfectants\/quemoxygen\/\"><img decoding=\"async\" class=\"alignnone wp-image-3537 size-medium\" title=\"quemoxygen soil disinfectant\" src=\"https:\/\/www.quelagrow.com\/wp-content\/uploads\/quelafert-quemoxygen-300x300.jpg\" alt=\"QUELAFERT\u00ae QUEMOXYGEN - Soil disinfectant for healthy crops\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.quelagrow.com\/wp-content\/uploads\/quelafert-quemoxygen-300x300.jpg 300w, https:\/\/www.quelagrow.com\/wp-content\/uploads\/quelafert-quemoxygen-150x150.jpg 150w, https:\/\/www.quelagrow.com\/wp-content\/uploads\/quelafert-quemoxygen-768x768.jpg 768w, https:\/\/www.quelagrow.com\/wp-content\/uploads\/quelafert-quemoxygen-100x100.jpg 100w, https:\/\/www.quelagrow.com\/wp-content\/uploads\/quelafert-quemoxygen.jpg 1000w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p><a href=\"https:\/\/www.quelagrow.com\/en\/bioprotectors\/soil-disinfectants\/quemoxygen\/\">View product<\/a><\/p>\n<h3>DIVENHO<\/h3>\n<p>It acts as a <strong>biological soil disinfectant<\/strong>.

Post-treatment strategies are as important as the disinfection itself.<\/p>\n<h3>Key actions to regenerate soil microbiota<\/h3>\n<ol>\n<li><strong>Add quality organic amendments<\/strong>: Mature compost, worm humus, or vermicompost. They not only nourish but also provide valuable microbial diversity.<\/li>\n<li><strong>Reinoculate with beneficial microorganisms<\/strong>: Apply products containing <strong>antagonistic fungi<\/strong> (such as <em>Trichoderma<\/em> spp.) or <strong>plant growth-promoting bacteria<\/strong> (PGPR, such as <em>Bacillus<\/em> spp.). These will colonize the soil and establish a protective biological barrier.<\/li>\n<li><strong>Encourage plant life<\/strong>: Avoid long periods of bare fallow. Use cover crops or green manures that keep roots alive and feed the microbiota.<\/li>\n<li><strong>Use biostimulants and soil regenerators<\/strong>: Products that improve soil structure and biological activity.<\/li>\n<\/ol>\n<p>This is where <strong>Quelagrow<\/strong> bioprotectants play a fundamental role as post-treatment biofertilizers and biostimulants, ensuring that the investment in disinfection translates into truly living and productive soil.<\/p>\n<p>Disinfecting agricultural soil is not incompatible with caring for its life. On the contrary, an intelligent, sustainable approach seeks to eliminate the problem (the pathogen) without destroying the solution (the beneficial microbiota). Methods such as solarization, biofumigation, and biosolarization, boosted with products like <strong>DIVENHO<\/strong> and <strong>QUEMOXYGEN<\/strong>, offer a viable path. The key to success is not just <em>disinfecting<\/em>, but <em>disinfecting and regenerating<\/em>.
