In hydroponic cultivation , as for any substrate, the addition of micro and macro elements helps in hydroponic cultivation , allowing the plant to absorb the substances necessary for proper development. These elements must be balanced correctly and vary according to the stages of growth or flowering.
The main elements also called macro elements that our plants need are:
- Nitrogen (N)
- Phosphorus (P)
- Potassium (K
In the phases of growth or flowering, the percentage of these elements present in commercial fertilizers must necessarily vary and balance according to the various phases.
Nitrogen (N) stimulates photosynthesis by increasing the plant development of branches, leaves and stems of the plant, an element therefore suitable for the vegetative phase of the plant, but good doses of potassium (K) in this phase are necessary for the development of the roots. Phosphorus (P) and potassium (K) are necessary elements for the flowering phase. These elements are related to the formation and development of flowers, the development of roots and the structure of the shoots. Potassium (K) for plants is of fundamental importance for correct growth as it is a fundamental element of numerous biological processes; the main function is the synthesis of sugars and the development of the organoleptic properties of plants by increasing the aroma and flavor of flowers and fruits. Potassium also regulates leaf transpiration by stimulating the opening of the stomata, which are superficial glands that eliminate water vapor.
The secondary elements called micro elements are equally important, some of these elements are:
- Calcium (Ca)
- Iron (Fe)
- Magnesium (Mg)
- Sulfur (S)
- Boron (B)
- Molybdenum (Mo)
It is important that none of these elements are missing in the nutrient solution in hydroponics, but above all their balance in the various phases is important.
In hydroponic caltivation , one of the main advantages is certainly the speed and explosiveness of plant growth, furthermore, cultivating in hydroponics allows you to effectively and precisely control the hydroponic nutrient solution with specific fertilizers, guaranteeing the plant the right amount of micro and macro elements.
Nevertheless, the accuracy with which the pH is kept stable guarantees correct absorption of nutrients.The flexibility in managing the fertilizers that we have in hydroponic system is absent in soil crops.In earthy substrates, nutritional elements are already naturally present which make balanced fertigation difficult.In hydroponic cultivation, almost all of the problems related to nutritional deficiencies or imbalances that occur on plants, is caused both by a bad use of fertilizers but also by the fluctuation of the pH: A pH that is too alkaline or too acid, completely cuts the absorption of some micro and macro elements vital for plant growth.Furthermore, poor fertilization weakens the plants, especially the cannabis species in the flowering phase; on the other hand, excessive fertilization can even burn the entire plant system and in some cases lead to the death of the plant.We deduce that the use of EC testers and even cheap pH testers is of fundamental importance if you want to undertake a hydroponic cultivation.
Rust is a problem often encountered by the organic fertilizer production equipment, especially in rainy days.
Although the machine is not exposed to rain, it will still find rust when it is used later.
Let's explain how to prevent the fertilizer facilities from rusting in rainy days.There is more rain in autumn.
In rainy season, people will store the organic fertilizer equipment in the designated place as usual, but when it is reused after rainy day, it will be found that the organic fertilizer equipment is rusty, some mechanical parts are aging, and some parts are wet.
They are not well preserved, easy to rust and shorten the service life.
The machine should be painted with antirust paint and stored in a ventilated and dry place.2.
The fertilizer production still needs to be operated by professional npk production line.
The chicken manure without fermentation and ripening is used as organic fertilizer after drying, which will ferment and ripen in natural state, which may harm crops and is not conducive to crop growth.
After high temperature decomposition, it does not contain harmful bacteria and insect eggs, which avoids the disadvantages of farm manure, such as easy to burn seedlings, odor, and many diseases and insect pests.Treatment mode of small fertilizer production lineFirst of all, the wheat straw is mechanically crushed by a pulverizer, then poured into the fermentation tank, mixed with water, added with sludge, and then added with chicken manure, sheep manure, rabbit manure, urea, etc.
The raw material of organic fertilizer begins to ferment and decompose.
After about 15 days of fermentation, the material is processed by the compost turning machine, so that the straw can rot completely and release the fertility, which is absorbed by the sludge, and the fertility of other organic fertilizers is absorbed at the same time.Then the material is crushed by the semi wet material pulverizer and sent to the drum screening machine for screening.
It can be used after 5 days of secondary fermentation.
