QUESTIONS AND ANSWER TO FOLLOW.... A~ WO0D ASH 1. chemical c0mp0und Ca4(PO4)2SiO4. 2. It is a lime chemical. B~ CHARCOAL Source; burnt wo0d. C~ LIMEST0NE Chemical c0mp0und CaCO3 are use as lime. ADVANTAGES/EFFECT OF A, B AND C 1. It improves the soil structure. 2. It increases microbial activities. 3. It increases organic matter breakd0wn. 4. It reduces the soil PH. 5. It enhances the m0vement of water and air in the s0il. EFFECT OF EXCESS OF A, B AND C... 1.Decreases the activities of soil microbes. 2. Change soil PH 3. Deficiencies of iron magnesium and copper. 4. Inhibit absorption of boron. 5. Decreases the soil phosphorus. SPECIMEN F~ MEASURING CYLINDER Pour the garden s0il in a measuring and add HCL acidto it. The soil becomes acidic as it turns blue litmusred. CAUSES OF S0IL ACIDITY 1. Use of acid fertilizer. 2. Leaching. 3. Accumulation of hydrogenion in the soil. 4. Heavy rainfall. 5. Presence of sulphur in the soil. 6. Purification in a water logged soil. EFFECT OF SOIL ACIDITY 1. Reduces soil microbial activities. 2. It reduces soil nutrient. 3. Leaching of soil nutrient. 4. It reduces rate of purification. 5. Leads to accumulation of toxic material like aluminum and manganese.. SPECIMEN I~ PIN. USES ~ it is used for making chain length. SPECIMEN J~ GARDEN LINE Uses ~ 1. for lining up beds. 2. For making straight rows when planting. 3. For partiti0ning of farm into plotduring farm lay0ut. SPECIMEN K~ HAND TROWEL USES ~ 1. For transplanting seedlings. 2. For mixing fertilizer with soil. 3. For digging holes for planting. 4. For sampling soil. SPECIMEN L~ MATTOCK USES ~ 1. For breaking hard soil. 2. For uprooting stumps. 3. For digging holes. MAINTENANCES OF K AND L 1. Straighten bent blades. 2. Avoid too hard and roughwork. 3. Rub the metal part with oil. 4. Clean and dry after use. SPECIMEM M~ COCONUT . It is a drupe. Agent of dispersal is water. SPECIMEN N~ SWEET PEPPER (CAPSICUM SPP) TYPE OF CROP: it is a berry. PROPAGATION: seed.
