Vitality, growth and last but not least the rearing success of your planting are essentially related to the soil quality and sensible greenhouse fertilization. The regulation of important trace elements and nutrients also prevents plant damage that can reduce yields.
Liquid fertilizer is often a good choice for the greenhouse
Garden owners' opinions differ more widely on hardly any other topic than on the subject of greenhouse fertilization. The fact that gardening close to nature completely dispenses with industrially produced fertilizers with chemical additives is just as clear as the insight to generate a heavily used greenhouse floor with targeted additions of nutrients and trace elements in order to make these ingredients available to the plants. However, it is undisputed that by over-fertilization with organic as well as inorganic soil conditioners as well much damage to plants occurs (can!) than if these nutritional supplements were dispensed with altogether.
The little compost is not always enough
A soil analysis from the laboratory clarifies very reliably to what extent the required nutrients are available at all and, which is just as important, whether they are available in an optimal concentration for the plants. However, a lack of nutrients or a lack of trace elements cannot be compensated for by adding compost alone, which may still contain pathogens and weed seeds. Therefore, inorganic or organic solid or depot fertilizers cannot be completely dispensed with, but only to the extent that the plants use them properly actually need for healthy growth.
Fertilize nutrients and their functions in the greenhouse
In the following brief overview, which does not claim to be complete, we will show you what trace elements and nutrients do or don't do (in the event of a lack of or incorrect supply) when fertilizing in the greenhouse.
| nutrient type | nutritional properties |
|---|---|
| nitrogen | Promotes growth of shoots and leaves; serves the plants for the formation of enzymes and proteins; |
| potassium | Regulates the fluid balance and serves to strengthen the tissue; promotes resistance to organic pests; |
| iron | Essential for chlorophyll and enzyme formation in plants; Use is particularly necessary on extremely calcareous soil; |
| sulfur | Important building block for the plant's own vitamins, proteins and enzymes; |
| phosphorus | Responsible for flower and fruit formation; important energy store of plants; |
| calcium | Promotes cell proliferation and the strength of cell walls as well as length and root growth in plants; |
| manganese | Necessary for the assimilation and the development of the plant's own enzymes; |
Liquid fertilizer: Easy to dose when growing
If an acute lack of nutrients in soil cultures is to be compensated for as quickly as possible, the greenhouse can be fertilized at the same time with the irrigation water. However, the dosage of the funds and the frequency of their use should be strictly according to the recommendations that printed on the packaging are to be carried out.
tips
If only the trace element deficiency of individual components is determined in the result of soil analyzes, very targeted fertilizer applications are sufficient for soil improvement. Special trace element fertilizers are commercially available for this purpose, for example only for an exclusively diagnosed iron deficiency.
