According to the cultivation technique we adopt (earth, hydroponics, aeroponics, coconut fiber, rockwool, etc ...) a fertilizer specially designed for the type of substrate must be used. As we mentioned in the previous paragraph, organic fertilizers on the ground, in addition to being often too dense and lumpy to work with pumps and irrigation systems, undergo strong variations in acidity and tend to rot when in contact with water and air in recirculation systems. or worse on rock wool.
With hydroponic cultivation, on the other hand, as the water is totally or almost devoid of nutritional elements, they must be added as mentioned in a well-balanced form, but above all it is necessary that they are perfectly soluble and fluid, to be absorbed directly by the roots of the plants
Since water is the fundamental basis for the nutrient solution, it is important that it is of good or acceptable quality. A water that is too hard or calcareous will certainly need corrections with products based on phosphoric, nitric or potassium acid in order to maintain the correct pH levels. It often happens to have excessively saline water, so it is important to check the percentage of Total Dissolved Solids (TDS) which must not exceed certain levels of salinity 200-350 mg / l, otherwise it will be necessary to filter the water with a specia resreve.
As already mentioned before we would like to emphasize that the correct use of fertilizers for hydroponics is very important for this kind of technique, but at the basis of a healthy and fruitful hydroponic culture, the correct levels of pH and EC (TDS) in the solution are decisive. nutritional. Only a well-balanced solution of EC and pH allows for rapid absorption of nutrients and success in cultivation.
Very superficially we could say that a pH between 5.5 and 6.5 is a correct value for almost all your indoor crops with flowering and fruit plants.
As for the EC (tds), which ultimately measures the amount of fertilizer in the nutrient solution, this value varies depending on the plant species grown. However, a value between 0.8 and 1.8 is the most suitable depending on the stages of growth or flowering.
The nutrient solution, which naturally tends to wear out and decrease as the days pass, can be topped up gradually, always rigorously restoring the pH and EC levels. However, it is advisable to empty the tank (if possible clean it) and put new solution every 7-10 days maximum.
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.
