| Summary: | 00oft2 . Data recorded during the growing season included 2 to 3 C cooler at both measured depths during daytime and additional nitrogen was incorporated. In the presence of additional nitrogen, the water holding capacity of the and plant dry weights. Soil moisture was two to three times differences in soil moisture due to polymer due to exceptionally high rainfall during establishment. Field study one incorporated hydrophilic polymers into field flower number, visual rating, soil moisture and temperature, greater at the higher polymer rates compared to control plots However there was no effect due to polymer incorporation in plots of petunias due to polymer incorporation. in the first greenhouse study which may have been included plant parameters, soil moisture, water loss and incorporation increased soil moisture by approximately 1 0%. incorporation. incorporation. However, marigold flowering was unaffected by incorporation. Temperatures of soils with polymers remained Leachate was collected on a daily basis and analyzed for maintaining soil moistures of 13- 17% up through the fourth moisture by approximately 50% in plots where no N03 and NH4 content. Data collected during the studies nutrient analysis in the plant, soil and water. of petunia and vinca were increased due to polymer on plant parameter, soil moisture or nutrient retention partially due to the well-watered conditions the plants Plant performance was poor for all treatments in this study plots of bedding plants including 25, 50, 75, or 1 00 lb/1 polymer incorporation. Field study two was similar to field polymer was decreased and there were no significant remained warmer at both depths during the night. Flowering Significant differences were found for all plant study one with the exception of the incorporation of supplemental nitrogen at the rate of 0.4 lb/100oft2 . Polymer Temperature differences were also similar to field study one. temperatures were also significantly different due to polymer The greenhouse studies investigated N03 and NH4 retention under drying cycles, polymer incorporation increased soil variables measured due to nitrogen incorporation. week of the study compared to 6% in the control plots. Soil were kept at. In,the second greenhouse study, conducted |
