How to roast the earth in the oven? How long, what temperature?

  1. I like
  2. 220 degrees. As long as strong pairs do not go.
  3. Do not roast in the oven soil for planting! With this heating, the soil burns out and becomes unsuitable for plant nutrition. The easiest way to till the soil is steaming. Take the metal bucket, pour into the bottom 2l oxen and fill the soil to the top, not ramming. Close the lid and put it on the stove (medium fire). After 40 min, the bucket is removed and cooled. The soil is ready for planting.
  4. The soil is flooded with hot water, loosened, carefully mixed, poured onto a baking sheet, put in the oven and calcined at a high temperature of 25-30 minutes.
  5. I use bags for the oven - very convenient
  6. While the smoke does not end.
  7. at the same time a stench for the whole apartment
  8. spread on a baking tray and stand in a hot oven for about 15 minutes.
  9. What tick should bite so that there was a need to kill the biological equilibrium established in the soil? do not forget that, after steaming, pathogenic microorganisms will develop in the first place, which can adversely affect the growth of planted plants (if, of course, the land is intended for this)
  10. In general, when cooking, most of the vitamins are lost, nutrients change structure and lose value
    The microwave oven generally changes the structure of the earth completely, but here's a recommendation.
    # Steaming in the oven. Wet earth is poured a thin layer on a baking tray, from above cover to avoid active evaporation of moisture, periodically mixing it is kept in an oven 1 for an hour at a temperature of 100-120 C.

    # Steaming in the microwave oven for a short time treatment of wet soil at high temperature. Wet land is placed in a special bowl or in a package of dense polyethylene (in the sealed packet of purchased soil, you must first make holes). The optimal steaming time of 0,5 liter of soil is 5 minutes at maximum mode. Either two sets of 2-3 minutes with soil mixing between treatments.

    # Steaming in water. The earth is covered in a metal container, filled with water until it is evenly moistened, covered with a lid and kept on low heat for 1 hour.

    # Steaming in a water bath. The earth is covered in a metal container, covered with a lid, put in a larger container with water that closes the container with ground for three-quarters, is kept on fire with a weak boiling of water 1-1,5 hours.

    # Steaming in a colander. The colander is lined with gauze in several layers or with a canvas cloth, they cover the ground. The colander is fixed over the tank with boiling water, from above is covered. Withstand on fire with a slight boiling of water 1 hour. During the treatment, the earth is periodically mixed for uniform heating.

    # The earth, poured a thin layer on a metal pallet, is spilled with steep boiling water with further drying.

    # Frost. The soil is kept in a strong frost with complete freezing. It is easiest to leave small packages with the earth for the whole winter on an open balcony. Freezing does not remove soil from many microorganisms and weeds.
    Heat treatment has also the reverse side immediately after it increases the risk of entering unwanted microorganisms into the ground and their active development in a sterile environment, the natural microflora of the soil is restored for a long time. Quenching the land without moistening instead of steaming leads to a change in the structure of the soil, turning it into dust. Exceeding the recommended soil treatment temperature (especially the purchased soil with numerous additives) can lead to the formation of undesired compounds.
    To revitalize sterile soil, it is recommended to use biochemicals Trichodermine, Planris, Baikal, Renaissance and others. In dry after heat treatment, dry biopreparation is added, or the soil is spilled with an aqueous solution.
    It is possible to sterilize only the most dangerous components (sod, leaf, humus, coniferous, heathy ground), and then add relatively pure peat.
    Sand, expanded clay, pebbles, gravel washed to clean water, fall asleep in a metal container, pour water and stand on fire with a weak boil 30-60 minutes.
    Bark, fern roots, sphagnum moss, cones are subjected to short-term treatment with boiling water before use.
    The risk of entering pests and diseases significantly decreases with the transition to substrates that do not contain humus and consist of peat, perlite, vermiculite, coconut fiber, bark.

    Chemical treatment allows you to get rid of pests and pathogens. The land mixture, spread out in a thin layer on a pallet, is poured with a solution of potassium permanganate (hot solution of potassium permanganate, 0,5-1 g per liter of water) or a pesticide (fungicide, insecticide, acaricide). The treatment of land with biologics containing microorganisms-antagonists of soil pathogens is more natural, but less reliable.

    Thermal and chemical treatment of the earth is carried out for 1-3 weeks before use to restore the soil microflora.
