Hello dear friend @lemouth, certainly sometimes life can be complicated especially when we have multiple occupations, which is also my case and I try to manage it as best I can.
As for your question, I think that if you can rely only on organic components, since it is the basis of life in the soil (microorganism), it is not complicated to get organic matter in agricultural production units, since there are always vegetable wastes that can be used for the production of organic and liquid fertilizers, there are also local resources such as legumes whose leaves can be an essential component in the development of these organic products for their adequate nitrogen content.
On a small scale also for our flower beds, we can obtain organic matter from our kitchen waste, particularly in my house we have Californian red worms for the decomposition of these organic wastes, obtaining a great liquid and solid fertilizer, the worms have a very nourished intestinal flora to decompose the organic material,
In short, I am not against synthetic products, I am against their excessive use, which can affect the environment and the economy of producers because of their high costs.
Thank you for your valuable comment, have an excellent and productive week.
