In the fall, special attention must be paid to preparing greenhouses and barns for the upcoming growing season. The soil in greenhouses accumulates a large amount of pathogens over the course of a season and it is not always possible to replace it with new soil. Therefore, it is important to properly treat, acidify and disinfect greenhouse soil in the fall. This article will explain in detail how to care for the soil in your greenhouse in the fall. You will learn more about How to Till The Soil in The Greenhouse by Bubgo article.
Tilling The Soil In The Greenhouse
If greenhouse plants were infected with Cladosporium, phylloxera, or other fungal diseases during the summer, their spores may have penetrated the soil and settled on crop residues. If no action is taken, these same diseases will ruin next year's crop and the gardener's mood.
To protect greenhouse soil, the first thing to do is to remove all plant debris from the greenhouse. Don't put them in the compost pile. It is best to burn them in a bucket to prevent the spread of mushroom spores in the vegetable garden.
To avoid spreading spores from dry and sick plants, their stems are cut at 4 inches (10 cm) above the ground and carefully removed from the structure. The rhizomes of diseased shrubs were then dugout with a pitchfork or spade and removed as well.
Tools and other gardening equipment were removed from the greenhouse and they were cleaned with a disinfectant solution. Clean them with the same solution so that wool, shade cloth, and netting can be used in the greenhouse the following year to avoid infecting crops through these items.
Methods of treating greenhouse soil
Ideally, the soil of the greenhouse should be treated with biological agents. For example, xylem can be introduced into it, which not only suppresses disease and disinfects the soil, but also destroys any remaining plant parts (small roots that are difficult to remove, etc.).
Tip: Remember that biological agents are only effective when the soil temperature reaches 50-59 °F (10-15°C). If the temperature drops below this temperature, the treatment may not be effective. It must be applied when the temperature drops below 50 °F (10 °C).
Peroxyacetic acid, which can be prepared at home, works well at the same temperature conditions.
1. Pour 0.26 gals (1 liter) of 9% vinegar into a glass bottle.
2. 200 mg of 3% hydrogen peroxide was added to the jar.
3. Cover the mixture and leave it in a warm place for 7-10 days.
4. One cup of water is diluted in 2.6 gals (10 liters) of water. Pour the prepared solution into the soil.
If the autumn cold spell comes earlier than usual and biological agents are no longer available, you can use a disinfectant - 100 ml in 2.6 gals (10 liters) of water). Up to 53 square feet (5 square meters) of greenhouse area can be treated with this solution.
An aggressive method is to treat with iron sulfate for eradication. Dilute 1.1 lbs (0.5 kg) of alum and 1.1 lbs (0.5 kg) of urea in 2.6 gals (10 liters) of water. The product was applied to the soil surface and all pathogens were killed. If the majority of plants in the greenhouse are diseased, iron sulfate may be used. If weather permits, Trichoderma can be applied one week after the eradication treatment.
Another method is to treat the soil with a manganese solution - 2 grams per 0.26 gals (1 liter) of water. Sprinkle the mixture over the seedbed with a rake so that it can penetrate more deeply into the soil. The water temperature for diluting the manganese solution should reach 149-153 °F (65-70°C).
You can also disinfect the ground with
Tip: All severe treatments will not only kill pathogens but also kill the beneficial microflora in the soil. Therefore, it is important to help the soil recover with organic preparations. These are usually applied to greenhouse soils as early as spring.
Soil Deoxygenation In Greenhouses
Properly acidifying the soil is equally important. Even if your soil reacts normally, it can become acidic at the end of the season after irrigation, mulching, green manure, and mineral fertilizer. To deoxygenate, sprinkle diatomaceous earth, chalk, or grass ash on your flower beds and then water the soil in the structure.
Then you can fertilize the soil with a little biomethane and compost. By the way, it is also advisable to fertilize the greenhouse beds in spring.
Sowing Green Manure Plants
In preparing the building for the next holiday season, you can they are also good at sterilizing the soil.
Greenhouses are planted in greenhouses.
Sinkers are not tilled after germination but simply left in the bed over the winter.
Tips: Crops are sown according to a rotation plan - the same crop is not planted in the same place two years in a row.
