ASSESSMENT OF THE IMPACT OF PHYSICOCHEMICAL QUALITIES OF SOILS IN GREYWATER USED FOR IRRIGATING LETTUCE PLANT (Latuca sativa)

Abstract

The study aimed at assessing the effects of physicochemical properties of soils in greywater use
for irrigation.Six weeks seeds of Lettuce (Latuca sativa) were sown in plastic flower pots
containing loamy soil, plant monitoring routine was done weekly and data were anlayzed using
excel while sampling of both water and soil were conducted before and after planting of which
the samples were taken for analysis to the laboratory for physical and chemical parameters. The
data obtained were analyzed using descriptive statistics.The pH, Ca, Mg, K, and Na levels in
water and soil samples were all within WHO (1984) recommended ranges, indicating that
greywater had no impact on soil quality. According to the report, research should be conducted
on a regular basis to investigate the qualities of some physic-chemical properties and harmful
compounds found in greywater irrigation and their impact on plant growth.
