Explanation:
Detailed explanation-1: -Environmental Regulation of Vegetative Growth Flooding also reduces the soil redox potential, increases the pH of acid soils (largely because of a change of Fe3+ to Fe2+), and decreases the pH of alkaline soil (mainly because of CO2 accumulation which eventually forms H2CO3).
Detailed explanation-2: -Agriculture: Floodwaters carry nutrients and sediments, which are deposited on flood plains, enriching the soil.. Rice paddies are flooded deliberately to take advantage of this natural fertilization process.
Detailed explanation-3: -This can be achieved through the use of grain legumes, which enhance soil fertility through biological nitrogen fixation, and the application of chemical fertilizers.
