  • Method of treating a soil
    Patent number: 4553351
    Abstract: Method of treating a soil particularly for maintaining or increasing the percentage of organic matter therein. This method which is carried out by simple surface composting, after spreading shredded forest residue and animal manure, is very interesting in that it associates the use of an agricultural technique known for its simplicity and low cost with the use of two basic materials produced each year in enormous quantities as industrial by-products for which no disposal means have been found.
