What things are made of plants
What do plants need to grow healthily?
Plants can apparently grow from almost nothing. A little bit of water, light, air and earth seem to be enough to turn a small seed into a whole bush. With the help of solar energy, they turn carbon in the air into glucosewith which they drive their growth and build cells. In fact, plants are so-called autotrophic organisms. This means that they make their own food. Of course, they cannot arise out of nothing. Complex circumstances and their precise coordination with one another are necessary in order to be a to guarantee stable, healthy growth. We'll take a closer look at what exactly is needed for this in this article.
Light: energy that gets everything going
Even if all components have to be perfectly coordinated and every single one of them needs it, you could light almost as the most important factor for growth describe. It splits the water molecules so that the further process can be initiated and photosynthesis is set in motion.
Too little light leads to so-called horny growth, whereby root development and leaf growth are neglected in favor of length growth, so that the plant can better get to a light source. This makes sense when other larger plants obscure the smaller one.
However, if there is not enough light at all, for example in the interior, the plant can logically grow as long and will not get any photon.
In addition, one can observe in the growth of plants that they always stretch towards the sun. The The shady side of a plant grows faster and fasterso that it leans towards the sun in order to receive maximum radiation. But not only in direction, but also The growth of the plant changes according to the type of light.
Depending on the intensity and wavelengths, different substances are formed or the plant generally grows more or less well.
To ensure this environmental factor one can artificial light in the form of LED plant light that cover all wavelengths required for growth and promise better results than pure monochrome light.
Air: carbon dioxide as the basis
The Carbon that the plant needs to build up, takes it out of the air. There she finds carbon dioxide (CO2). From the inorganic CO2 important organic compounds are produced that act as building materials and energy sources for other parts of the ecosystem.
Our vegetable food, for example, serves us as a source of energy because the plant process the carbon from the air can.
Minerals, nitrogen and other nutrients
Having arrived at the nutrients that the plant needs for healthy growth, let's get into the subject of phytotrophology. A complex term that basically means nothing else than Nutrition of the plant (Phyton means plant and trophology nutritional science). In principle, plants are autotrophic organisms. You can basically produce your own food.
They do that in photosynthesis, wherever they are produce glucose and oxygen from carbon dioxide and water by adding energy in the form of light. With this glucose they set their processes in motion so that cells can be built up. To do this, they also need nutrients from the soil, which they absorb through the roots.
These include the following substances:
These simple organic compounds or to some extent individual elements can be the plant toprocess complex molecules. If one of them is not available in sufficient quantity or too much of it, although this can be different for each plant, deficiency symptoms or symptoms of oversupply, such as weak growth, discoloration of the cells, etc.
Water for the transport of nutrients
The water is there for them Dissolve nutrients and put them in the plant and to transport into the cells. In addition, the water in the cells brings stability as it exerts pressure in the cells. Insufficient internal cell pressure causes the plant to wither. If too much water is available, it can lead to a lack of oxygen, which is just as counterproductive.
Core, main and micronutrient elements
Let's take a closer look at that Elements and nutrients a plant needs to grow, they can be divided into 3 categories, namely core, main and micronutrient elements. Depending on the category, they are more or less important or necessary in different quantities.
|Core elements||Main elements||Micronutrients|
The ingredient that is missing from this listing is light. As already mentioned, the light provides the necessary energy to keep all these substances in the Process of photosynthesis and growth integrate or even get the process going.
Soil conditions and temperatures
The ingredient that is missing from this listing is light. As already mentioned, the light provides the necessary energy to keep all these substances in the Process of photosynthesis and growth to incorporate or to get the process going at all.
Other abiotic environmental factors are also important, including the Soil conditions and temperatures. The floor is allowed, for example not too firm and too damp otherwise the roots cannot form properly and without roots, the plant does not get any nutrients.
In addition, the pH value of the soil is crucial and it must not be too cold or too hot.
Liebig's law of the minimum
In terms of plant growth, Liebig's law of minimus is particularly interesting. It says that there must be a certain minimum of all components. If even just one element is not available, all the others can be supplied en masse, the deficiency would only be all the more apparent.
Has a For example, plant a phosphorus deficiency and if the lighting conditions are optimized, the symptoms of deficiency can become even more intense.
The larger the discrepancy between the undersupply and the other supply values, the worse it looks with the growth. So all factors must be taken care of equally well, to ensure the healthy growth of the plant.
The most important prerequisites for healthy plant growth are:
✓ Carbon dioxide and oxygen
✓ Minerals and nutrients
✓ Soil consistency
