He analyzed the whole plant.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The 3 observations<\/h2>\n\n\n\n<p>The reason for this analysis was three observations:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Plants grown in soil not previously cultivated are strong, vigorous and very productive.<\/li>\n\n\n\n<li>Each subsequent year, the productivity of plants grown in the same soil declines.<\/li>\n\n\n\n<li>The addition of N-P-K based chemical fertilizers does not restore the initial soil vigor and therefore the initial productivity of the plants.<\/li>\n<\/ul>\n\n\n\n<p>By analyzing the whole plant Julius Hensel came to different conclusions.<\/p>\n\n\n\n<p>For example, the proportion of Phosphorus in the whole plant was much lower than what Justus von Liebig found by studying only the seeds.<\/p>\n\n\n\n<p>He also found data not mentioned in Justus von Liebig&#8217;s study.<\/p>\n\n\n\n<p>Dr. Julius Hensel argued (remember we are back in 1893) that the use of chemical fertilizers on crops has the following negative effects:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>They poison the soil by destroying beneficial bacteria, insects and animals.<\/li>\n\n\n\n<li>They create diseased, unbalanced plants that cannot withstand disease and pests and thus need chemical insecticides to survive.<\/li>\n\n\n\n<li>They favor the spread of disease to humans and animals that feed on these &#8220;sick&#8221; plants.<\/li>\n\n\n\n<li>Farmers are financially ruined as they spend huge amounts of money to enrich the soil with chemical fertilizers that are easily washed away in the rains with irrigation water. Thus they are forced to buy fertilizers again and again.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">The 9 nutrients needed by plants according to Dr. Julius Hensel<\/h2>\n\n\n\n<p>Dr. Julius Hensel argued that according to his studies, plants need the following nutrients in order to grow properly, to be useful food for humans and animals, and to be resistant to diseases and pests:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>potassium (potassium)<\/li>\n\n\n\n<li>soda (baking soda, sodium bicarbonate, bicarbonate of soda)<\/li>\n\n\n\n<li>lime<\/li>\n\n\n\n<li>magnesium<\/li>\n\n\n\n<li>iron<\/li>\n\n\n\n<li>manganese<\/li>\n\n\n\n<li>sulphur<\/li>\n\n\n\n<li>phosphorus<\/li>\n\n\n\n<li>florine<\/li>\n<\/ul>\n\n\n\n<p>All of the above ingredients are found in rocks that, if added to the soil in the form of powder, will dramatically increase plant health and productivity.<\/p>\n\n\n\n<p>This article, is a humble introduction to the book &#8220;<strong>Bread from Stones<\/strong>&#8221; by <strong>Dr. Julius Hensel<\/strong>, which can <a title=\"Bread from Stones\" href=\"https:\/\/soilandhealth.org\/wp-content\/uploads\/01aglibrary\/010173.hensel.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">download and read here<\/a>.<\/p>\n\n\n\n<p>It is up to each reader to evaluate and adopt or reject Dr. Julius Hensel&#8217;s views.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">References<\/h2>\n\n\n\n<p><a title=\"Bread from Stones (PDF)\" href=\"https:\/\/soilandhealth.org\/wp-content\/uploads\/01aglibrary\/010173.hensel.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">Bread from Stones (PDF)<\/a><br>\n<a title=\"Julius Hensel\" href=\"https:\/\/en.wikipedia.org\/wiki\/Julius_Hensel\" target=\"_blank\" rel=\"noopener noreferrer\">Julius Hensel<\/a><br>\n<a title=\"Justus von Liebig\" href=\"https:\/\/en.wikipedia.org\/wiki\/Justus_von_Liebig\" target=\"_blank\" rel=\"noopener noreferrer\">Justus von Liebig<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Can bread be produced from stones?

Every day I learn new things. I am experiencing what Greek philosopher Socrates said: \"all I know is that I know nothing\" (\"\u0395\u03bd \u039f\u03af\u03b4\u03b1, \u038c\u03c4\u03b9 \u039f\u03c5\u03b4\u03ad\u03bd \u039f\u03af\u03b4\u03b1\"). I perceive my self as always a student. I created kalliergo.gr back in 2010, charmed by the plants magical world. I am a Biomedical Engineer, holding a MSc degree on E-Business. For a living I help businesses to grow online. I am not an agronomist but wish I had also a degree on agronomy.
