LIVING SOIL - Soil breathing.
Home gardening has become popular hobby recently. Those who cannot grow their own vegetables, spices and fruits in a garden, use the option to purchase such crops from small farmers or from so-called organic farms. Growing and selling crops under the name of bio has a lot of rules, one of them is limited artificial fertilization. Mr. Rabbit would like to grow his own vegetables, also, if possible, with a minimum of artificial fertilization. The best is to have land with soil containing many soil organisms. Mr. Rabbit has an opportunity to buy a land in different locations, but he does not know which siol has the best quality.
Help Mr. Rabbit with choosing the best option to gain soil with the greatest number of microorganisms.
