| Abstract:
The effect of the application of a concentrated beet vinasse (with P added) as organic fertilizer (ca. 4 and 9 t ha-1) on radish seedling emergence and fresh matter production was studied in a glasshouse. In general, neither dose of vinasse interfered with radish emergence in three different soils of SW Andalusia (1st horizon) used as substrates. Furthermore, both treatments with vinasse occasioned higher yearly fresh matter production of radish than those occasioned by two parallel inorganic fertilizer treatments that added similar amounts of N, P2O5 and K2O. Despite its high salt content (ca. 2% Na and Cl), concentrated vinasse may be a good organic fertilizer when properly used. | |
