<p>PROBLEM TO BE SOLVED: To maximize the growth of crops by the behavior of microorganisms without applying a chemical fertilizer and while decreasing the amount of an organic material or an organic fertilizer so as to be <=20% of the ordinarily required amount, to improve the yield. SOLUTION: A soil is cleaned by using the microorganisms consisting essentially of photosynthetic bacteria without using agrochemicals and chemical fertilizers for 1-3 years, and the crops are grown in the resultant soil with no fertilizer or with the organic material or the organic fertilizer in the amount of <=20% of the amount ordinarily required by the crops by applying the photosynthetic bacteria and microorganisms capable of supporting the bacteria, or applying the bacteria and the microorgartisms after activation to enable the components in the atmosphere to be utilized as the fertilizer.</p> |
