My dear friend @carlir, these are undoubtedly great advances that could be considered multifunctional, because they have repercussions in many aspects, especially because you mention that the intention is that there is a progressive release of the elements that are contained in the particles. Let's wait to see the cost that the use of technology will have, because if it comes to equate with the costs that are obtained in fertilizers, could come to replace them, anyway for my part I will continue trying with more ecological and natural alternatives.

See you later brother, excellent article, have a great week.
