Fertilisers Effect On Duckweed

491 Words2 Pages

• Duckweed (Lemna minor) is a member of the Lemnaceae family (Monette et al. 2006) it is a small plant that floats on the surface of still or stagnant water that is usually rich in nutrients (Keddy 2010). It was seen that Duckweed thrived in areas of high nutrient content, high sunlight and warmer temperatures (Taylor 2011) .It was also seen that fertilisers contained nutrients, such as nitrates, which greatly influences duckweed growth. Duckweed is also used for feed for farm animal, such as ducks, and it is also used to reduce nutrients in eutrophic environments (Ansari and Khan 2008, 2009, 2011); therefore this experiment was done to determine the effects that high concentrations of fertilisers cause on Duckweed by repeatedly adding varying

    According to Harrison Eutrophication is the excessive production of algae and higher plants through the enrichment of waters by nitrogen and phosphorus. Phosphorus in the form of phosphate is the limiting nutrient as the amount of biologically available phosphorus is small in relation to the amount needed for algal growth. Harrison states that sources of nutrients can be discrete, (sewage), or diffuse, (farmland fertilizers).

  • Milkweed Bug Experiment Lab Report

    928 Words  | 4 Pages

    To test the hypothesis the impact of temperature on milkweed bugs, they will be placed in three different temperature conditions. The temperatures include: 10°C (refrigerated), room temperature 22°C and at 28°C. These various temperatures represent the lowered temperatures from the milkweed bugs optimal temperature (28°C). The day and light cycle for these conditions will be 16L:8D. To test the hypothesis of the effect of light regime on development, milkweed bugs were placed in 22°C condition with a 16L:8D cycle and 22°C condition with a 2.5L:21.5D cycle. About 35 milkweed bug eggs will be placed in a clear container for each treatment group.

  • Radish Plant Experiment

    924 Words  | 4 Pages

    The plants with 200 ml topsoil were projected to have the highest average height according to the original hypothesis of increased plant growth due to an increase on the amount of topsoil added. Moreover, the original hypothesis was refuted as the plants with no topsoil in the control had a higher average height than the plants with 25 ml topsoil. The mixed red and green color on the leaves of the plants with 25 ml topsoil indicated possible deficiencies in phosphorus which might have slowed their growth. Moreover, the mixed red and green color on the leaves of the plants in both 100 ml and 200 ml topsoil also indicated a possible phosphorus deficiency which may have resulted in the slower growth of the plants despite having greater amounts of topsoil. The experimental results might have skewed due to the over fertilization of the radish seeds which might have led to excess nutrient levels which are unsuitable for radish plants as they require little to no fertilization for growth (Chase, 2018).
