- 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.High buffering capacity means the soil has more sand than soil with low buffering capacity. True or FalseHigh buffering capacity means the soil will retain more nutrients than soil with low buffering capacity. True or False
