THE GROWING PLANT 49 By the time the plants had used up the food of the endosperms their roots were ready, if the soil was in good condition, to support the young plant. APPLYING THE LESSON 1. How can you help the soil to get air? Look at the field shown in Fig. 30. It has been deeply plowed, and then harrowed until the soil is open and finely grained. Cannot plenty of air press into such soil ? 2. How can you help the soil to get warmth ? Will not the deep plowing, and the harrowing, and fining of the soil described above open the way for sunshine to flood in

How can you help the soil to get air? Look at the field shown in Fig. 30. It has been deeply plowed, and then harrowed until the soil is open and finely grained. Cannot plenty of air press into such soil ? 2. How can you help the soil to get warmth ? Will not the deep plowing, and the harrowing, and fining of the soil described above open the way for sunshine to flood into the soil ? 3. How can you help the soil to get enough moisture and yet keep it from getting such an amount as to drown the young plant? In Fig. 31 we see one way to help. Do not the ditches like the one shown in the figure carry away water that would keep the ground cold and soggy? Note in Fig. 32 how hard the soil is packed. \\'ould water run off such soil or would it sink in to be used at need by the young plant ? Do you see, then, that if you want the tiny young plant to get the air, moisture, warmth, and food that will enable it to do its best for you, you must give it a deeply tilled, harrowed, and fined seed bed in which to grow ? As soon as the germ awakens into life it sends a tiny root, known as the root sprout (Fig. ^2))y '^^'^^^ the soil. This root sprout branches later and forms. Fig. 32. A Packed Soil.
