In this article some measures are discussed to improve the yields and quality of organic (and conventional) agriculture with sea minerals, ditch dredge and rock flours.Sea minerals restore the health of plants, animals and men. These sea minerals result in healthy urine and dung of the animals. This dung is a good basis for a healthy plant growth. The dung should also be mixed with carbon rich materials (straw; elephant grass; natural hay) and with earth, stone meal or ditch dredge. By binding the nutrients with carbon and earth particles the putrefactive microbes are avoided and in this way the breakdown of organic nutrients in inorganic salts is prevented. The symbiotic microbes hold the upper hand. They transform the nutrients in microbial protein and other organic compounds, and, once in the fields, help the plants to collect the organically bound nutrients from the soil and humic compounds and transport them to the plants.Rock flours are also a good source of fresh macro and trace elements. The preferable type of rock flour depends among others on the type of soil, and the already available elements. Microbes are necessary for freeing the elements from the rock flours.The yields and the quality in organic agriculture rise then for three reasons: more plant available macro and trace elements for the crops. And the presence of the symbiotic microbes which free and supply the nutrients for the plants. To support these farmers in animal husbandry should give less protein and especially less Non Protein Nitrogen and Non Protein Sulfur in the feed of the animals in order to improve the quality of the dung and the compost.For many centuries farmers used salt, sea minerals, earth, ditch dredge and rock flours to improve the quality and quantity of the animal dung and plant residuals. And although some scientists have confirmed their results, the overwhelming majority of modern agricultural science has ignored this and persisted her own ideas about the necessary mineralization of nutrients before plants can take them up as salts for their growth.Farmers who buy artificial fertilizers pay yearly 100-150 billion US dollars solely for the pollution of the environment, because of the huge losses of nitrogen and phosphate. Also a lot of potassium is lost, but the effects of potassium salts on the ecosystems are not investigated.
