Which fertilizer to choose?


NPK chemical fertilizers In hydroponics, chemical NPK fertilizers cause growth and yields proportional to their contributions, and insect, fungal, bacterial and viral risks. The Redox analysis shows us an oxidation among our measurements, the highest; the mineral balance from nitrogen to molybdenum is ideal, but micro and nano-minerals are absent. The visual quality is at the top, but they are often deficient and tasteless, to the great disappointment of the consumer who ultimately is not mistaken, and who curses, even sulks! In a saturated market, the consumer wants taste and health. Used in our soils, these same fertilizers destroy soil microorganisms. If you know that 80% of the mass of life on Earth is in our soils, then it goes without saying that this is a vital topic. Gradually, our soils become substrates like hydroponic crops with therefore nano-mineral deficiencies. For the plant, this has consequences for its resilience and its immune defences. Although in “nano” quantity, numbering 65 nano-minerals, they are essential for the production of protein chains that serve both for the growth and defense of plants. Once deficient, the crops are weakened and susceptible to biotic and abiotic pressures (insects, fungi, climate change, etc.), hence the question from our customers: “Do you have a product against that? », and if the consumer eats « deficient products » then do you believe that he does not become so? Look at the proliferation of dietary supplements! Eating to deplete, isn't that a paradox? FYI, to within 0.03%, we have the same mineral composition as plants. Once caught in this gear, we enter the paradigm of struggle. This vicious circle becomes a habit and quickly a reality of which it is difficult to imagine that there could exist another reality whose paradigm is quite different from that of the struggle. Yet permaculture, or certain primary forests, show us positive signs that it is growing well and that there is no struggle. Changing the paradigm requires certain understandings and observations. A synthetic (chemical) NPK fertilizer is a (laboratory) response to plant nutrition, and is widely consumed simply by its price advantage and ease of use.



A new trend in organic or organo-mineral fertilisers? Seeing the damage caused to our soils, the alternative (almost cultural linked to the intensity of our animal husbandry) is the so-called "organic or organo-mineral" fertilizer, made up of animal waste more or less mixed with slaughterhouse residues. As breeders and slaughterhouses want to get rid of it, logically, it is an attractive NPK source also by its price. The catch is that even though it is considered “organic matter” input, this input does not increase the stable humus in our soils, so organic matter levels tend not to increase. In addition, it requires considerable energy to be digested by the microorganisms that take the place of those present to regenerate the soil and the plants. Soils are depleted of oxygen, insect pests proliferate and in many cases the so-called "weeds" proliferate: a real concern especially for organic, right? At most, these organic fertilizers contribute, apart from their nutritive role, to a mechanical improvement of the soil structure. Have you noticed that in a fertile forest, no animal or cow makes 20 to 40 tons per hectare of droppings/waste? Fertile forest is created from leaves falling to the ground and digested by microorganisms, eventually forming a beautiful clay-humus complex. Putting in such quantities of slaughterhouse waste and manure is a bit like giving meat to a cow, isn't it? Moreover, many of our analyzes show no improvement in soil fertility, as well as an increase in the risk of insects and diseases. In the forest, it is the plant that feeds the plant. And that led us to only offer the vegetable source, logical, right?




Vegetable fertilizer By using a plant fertilizer, we find that this has no negative impact on the soil and that in the presence of SolStart and more, combined with a plant compost and/or plant cover, the soil regains the properties of fertile primary forest. The mineral balance is quickly restored, including nano-minerals, the soil gains stable humus, becomes airy, desalinated, becomes loose. We also note that the soil absorbs and retains water better and releases more of it, which is not a luxury in these times of climate change, its microbial activity is greater, earthworms abound and the smell of undergrowth is present – ​​the soil is alive again! It is clear to our user customers that even if the price per kg is higher, they consume less anyway for a given yield, and the quality of the harvests, their preservation and their taste no longer have anything to do with what they knew before. For those who practice plant cover, they are a very relevant complementary solution.


I don't know of any of my clients who backtrack after working with their plant fertilizers. It's also because it brings them in, isn't it? Apart from preserving the soil, with their low oxidation and salinity, by increasing the quantities for more yield, instead of making the plants susceptible to fungal and insect pressures, they strengthen the plants and make them more resistant to these same pressures . Ah, how good this paradigm of abundance is: "I produce more with less risk, with more yield, more quality, and it's good for health and the environment, and as a bonus I earn more 'silver ! ".
