Place dishes under each bottle to catch the <br />water which runs through. Next pour one cup 01 <br />water into each bOil Ie and time the percolation unl il <br />waler begins dripping into the dish. Based on this <br />experiment. which soil would be the best one lor use <br />in a garden? Loam or woods soil, depending on their <br />composition. <br />Why? <br /> <br />The most absorbant soil with the highest organic <br />nutrient value would be the best garden soil. <br /> <br /> <br /> <br />Mark out two 3' square plots of tilled soil. Rake both <br />flat and leave one in this slate. Design an irrigation <br />pattern to efficiently supply imaginary crops on the <br />2nd plot. Utilize gravity to help distribute the water. <br />Check the effectiveness of your system by running a <br />hose at the same inlet point for each plot. Time the <br />water distribution and observe the results fOr <br />thorough coverage. What happened? <br /> <br />PLOT A <br /> <br />The water will flow indiscriminately, depending <br />on ffow speed, water Quantity, depressions in the soil and <br />soil absorbancy. <br />PLOT B <br /> <br />The water should reach all sections of the plot <br />and thus provide better and more consistant coverage. <br /> <br />WATER IN THE GARDEN <br /> <br />Plant 3-4 beans in each of lour 4" clay pots filled with potting soli or garden loam. Using the following watering <br />schedule, observe and recOrd the results for one month. <br />Pot #1 1 Quart of water once a week <br />Pol1t2 1 cup of water every day <br />POI #3 no waler <br />Pot #4 Take core samples every day With a clear plastic straw and lightly water when the SOil begins to dry. <br /> <br />GROWTH RECORD <br />HEIGHT (IN CENTIMETRES) DESCRIPTION OF PLANT HEAL TH <br /> <br />~ <br />~ <br />Tii <br />~ <br /> <br /> <br />-18- <br />
