- The normal state of cations and anions in a soil is in the hydrated state. TRUE OR FALSEAn extremely acid soil generally limits the availability of many nutrients in the soil. True or FalseEssential Plant Nutrients Chemical Chemical forms absorbed Element symbol by crop plants Primary Nutrients Nitrogen Potassium Phosphorus Secondary Nutrients Calicium Magnesium Sulfur Micronutrients Boron Chlorine Copper Iron Manganese Molybdenum Nickel Zinc
- When the soil is acidic, plants cannot grow on it. True or FalseSoil could be deficient in any of the following nutrients. If you had to supply one of these to the soil, which would be required in the smallest amount? Nitrogen 2. Potassium 3. Phosphorus 4. Sulfur 5. IronWhich element is responsible for causing soil salinity?At what concentration does the soil become saline?
- Write T on the blank provided if the statement is correct. If it is false, underline and replace the word(s) with the word(s) that will make the statement true. Calcium carbonate is highly soluble in water in which calcium element is easily release to correct soil pH. The degree of fineness of lime is not dependent to the speed of checking soil acidity. Carbon is released back to the atmosphere during decomposition of organic materials. Mineralization of nitrogen decreases if the water filled pore space is below 50%. Soil carbon mineralization increases as the moisture content of the soil increases to a certain level and may drop if soil is fully saturated with water. Nitrifying bacteria that obtain carbon from carbon dioxide prefer reduced zone to nitrify nitrogen to available form.organic component of soil formed by the decomposition of leaves and other plant material by soil microorganismsTortuosity has to do with the straight or curvy pathway water must take as it moves downward through the soil profile. TRUE OR FALSE
