THE EFFECT OF THE INTERACTION OF FERTILIZATION WITH MACROELEMENTS ON THE PRODUCTION OF TEMPORARY GRASSLANDS ESTABLISHED IN ARABLE LAND

Abstract

In the complex of measures for the establishment, maintenance and use of temporary (seeded) grassland, fertilization is a major factor in achieving  large, good quality, constant and for as long as possible.

For the ecopedological conditions at S.C.D.A.  Şimnic- Craiova, in the fertilization of temporary non-irrigated meadows can be used practically with the same efficiency, ammonium nitrate, urea and especially nitrocalcare. 

The administration of nitrogen at the level of the dose of N₁₂₀ divided by crops, shows very significant increases in yield.

On the P₇₀ agrofounder, ammonium nitrate, nitrocalcar and urea achieved increased biomass productions between 7,3-8,3 t / ha d.s.
