IMPACT OF FERTILIZERS SYSTEMS ON THE ROOT AND STUBBLE REMAINS ACCUMULATION OF THE PERENNIALE GRASSES ON PODZOLUVISOIL LOAMY SAND SOIL
The purpose of the present article is to explore the impact of fertilizers systems on organic matter accumulation by the roots and stubble residues of different species of perennial grasses. Based on the field experiment on Podzoluvisoil loamy sand soil there is an observed tendency of the root residue accumulation increase by the impact of fertilizers. Example of calculation of mass of roots and stubble residues by dry matter yield and converting theirs into manure has been presented.
