Abstract

Pocket penetrometer can be useful tool to quantify the evaporation
rate from calcareous soil and help the user in decision of irrigation scheduling
espicially, tor vegetable crops grown in greenhouses. The multiple linear
equations showed signifICant correlation between fenettation resistance
values (PR), ranging between zero and 4.5 Kg. em' , and evaporation, that
equal soil moisture depletion (SMD), volumetric moisture content (9y), calcium
carbonate, wet bulk density and soil fractions.
