Water and nutrition supply in relation to plant moisture supply and fertilization of pot plants

Acta Horticulturae (35): 41-48

Water and nutrition supply in relation to plant moisture supply and fertilization of pot plants

In a pot experiment, gloxinia received nitrogen rates of 100, 200, 300, 400 and 500 mg N per litre substrate. The soil moisture levels were 90, 65 and 40% of the substrate water capacity. The salt concentration of the substrate solution seemed to be much affected by moisture supply and N rate, implying that total suction rather than matric sunction should be regarded as representative of soil moisture availability.
