How to store fertilizer residues in winter: every summer resident should know this

Not a single normal summer resident will agree to throw away something for which money was once paid, especially when it comes to fertilizers.

  • Mineral fertilizers
  • Liquid fertilizers
  • Biofertilizers
  • organic

We will tell you what to do with the remains of various fertilizers – mineral and organic, as well as liquid mixtures.

If you just put them somewhere in the pantry or shed, then they are unlikely to retain all their useful properties until the next season. But throwing away all the same, the hand does not rise.

Mineral fertilizers

Powders and granules of mineral fertilizers should be stored in accordance with the manufacturer’s recommendations. Often they are not affected by the temperature regime, but high humidity can make them unusable. First of all, this applies to open packaging. Additives in factory sealed containers will be reliably protected from moisture.

Liquid fertilizers

Mineral fertilizers in liquid form are not afraid of moisture, but they are afraid of negative temperatures. In frost, they crystallize, then exfoliate, precipitate, and the nutrients pass into a form inaccessible to plants.


These include Ekomik Harvest, Baikal EM1, BTU Biocomplex, etc. It is also important to observe the temperature regime not higher than 20-30 and not lower than 0 degrees Celsius.


1. Ash is the easiest to store in winter. It is enough to put it in a suitable sealed container and put it in a dry shed, where it will stand for several years.

2. Manure needs certain conditions, otherwise it will lose up to 40% of nitrogen and other useful compounds. It is best to put manure in a pile, without tamping, 1.5-1.8 m high. After 3-5 days, pathogenic microorganisms and weed seeds will die in it and it can be compacted by watering or covering with peat (earth) with a layer of up to 40 cm.

When the pile is completely compacted, it is covered with a film and, if possible, with snow.
