When applying mineral fertilizers to the soil, the gardener and gardener needs to know that one faceted glass with a capacity of 200 g holds:

  • superphosphate - 185-200 g,
  • phosphate rock - 310-360 g,
  • potassium chloride - 185-190 g,
  • fertilizer mixture - 180-200 g,
  • fluff lime - 120 g,
  • wood ash - 90-120 g.

One 10 L bucket contains:

  • horse manure (fresh) 8 kg,
  • manure with sawdust - 5,
  • cow dung - 9,
  • bird droppings - 5,
  • humus - 8,
  • dry peat - 5,
  • turf land - 12,
  • old greenhouse or compost soil - 10,
  • wood ash - 5 kg.

In the reference literature, the norms of mineral fertilizers per 1 kg of potatoes, vegetables, fruit and berry crops, flowers are given in kilograms of the active substance.

In order to calculate the rate of any mineral fertilizer per 1 hectare, and then per 100 m², you need the amount of active ingredient required to be applied to the soil per hectare (kg), multiply by 100 (constant effective number) and divide by the amount of active substances in the fertilizer we have in percent.

Suppose that according to the norm, 60 kg of nitrogen must be applied on an area of ​​1 hectare. Of nitrogen fertilizers, we have urea, which contains 46% nitrogen. In this example, the need for urea per 1 ha will be (60x100): 46 = 130.4 kg, and for 100 m² - 130.4: 100 kg = 1.3 kg.

To determine the texture of the soil, it is enough to take a handful of soil from the topsoil, add water to it and stir well until it is pasty. Roll a thin rope from the resulting mass and shape it into a donut. If the rope does not crack during bending, the soil is clayey, if cracks form on the bend, it is loamy. You cannot knead the "dough" out of sandy soil.

The acidity of the soil will help you determine the weeds growing in your area. On acidic soils, as a rule, horsetail, pikulnik, small sorrel, toritsa, veronica, mint, plantain, ivan da marya, white beetle, heather grow. On slightly acidic and neutral ones - odorless chamomile, field bindweed, coltsfoot, thistle, wheatgrass, clover.
