Although the roots of the plants growing under glass are not visible and grow underground Soils, compost, substrates and the soil used for a greenhouse is important for growth and well-being. Not to forget a very healthy one Soil is inhabited by many useful living things, which play a key role in the healthy rearing of plants.

Soil for greenhouses and soil fertility
Basically, the soils for greenhouse plants do not differ from those for outdoor planting. They make the difference higher floor temperatures under glass or foilthat allow the dismantling and remodeling process of the soil components to take place much faster. Soil fertility is mainly characterized by:
- the six levels of pH (neutral to extremely acidic);
- the rootability of the earth for the greenhouse;
- the power of the soil to hold air and water;
- the warmth of the earth;
- the nutritional content and its continuous availability;
Soil analysis as the basis for high-yield planting
Laboratory tests of soil samples from allotment gardens came to the conclusion that the majority of soils are oversaturated with potassium, phosphorus and calcium. The reason: Compost, manure, lime and mineral fertilizers contain many more nutrients in the soil than plants can use up. It is therefore advisable to a soil analysis in the laboratory to have made, which reflects the actual condition of the greenhouse soil and helps to exclude malnutrition of the later planting. It is advisable to take a sample (500 grams in total and well mixed!) ten different places in the greenhouse.
Homemade soil for a greenhouse
If the result of the laboratory sample suggests that the soil has a good overall structure, the Greenhouse soil is easily produced by adding substrates and other additives will. The following overview shows some examples:
| Art | mixture |
|---|---|
| Peat-free potting soil | 25% bark humus, 25% garden compost, 50% garden soil or: 35% wood fiber, 30% bark humus, 25% garden compost, 10% clay |
| Sowing soil | 1/3 ripe compost (compost soil), 1/3 washed Quartz sand(€ 15.15 at Amazon *) (0 to 3 mm), 1/3 peat |
| Soil for alpine plants | 1/3 ripe compost (compost soil), 1/3 good garden soil, 1/3 peat - possibly with sand |
| Cactus soil | 1/3 sand, 1/3 lava or primary rock gravel or expanded clay granulate, 1/3 standard soil |
| Soil for the propagation of cuttings | 1/2 peat, 1/2 washed quartz sand |
| Plant / potting soil | 1/3 ripe compost (compost soil) or bark humus, 1/3 good garden soil, 1/3 peat |

Tips
The soil for your greenhouse can also be easily removed at certain intervals by planting Green manure plants be improved. Particularly good values can be achieved with spelled, field beans, alfalfa and winter vetch.
