Guava cultivation thrives best in soils characterized by a pH of _____________________?
Show answer Hide answer
Answer: A. 4.5-8.5
Explanation
Guava cultivation can adapt to a broad range of soils, thriving well across a pH range of 4.5 to 8.5. This exceptional adaptability allows guava trees to flourish in moderately acidic to alkaline conditions. Roots tolerate diverse soil chemistry better than many other sensitive tropical fruit species. Soil pH measures hydrogen ion concentration, significantly influencing nutrient availability to plants. Guava is a hardy subtropical tree capable of tolerating poor soil fertility and drought. Optimal root respiration requires well-drained soil profiles regardless of the broad pH tolerance.
Agricultural developers plant guavas in marginal lands where other fruit trees fail to grow. Soil testing ensures proper nutrient management even within the wide acceptable pH spectrum. Farmers achieve successful yields across diverse geographical regions due to this environmental resilience. Option B proposes a narrow pH range of 5.5 to 7.5, ignoring the hardier adaptability limits. Option C suggests alkaline soils from 7.5 to 9.0, missing the lower acidic tolerance threshold. Option D lists 6.5 to 7.5, representing neutral soils rather than the full hardiness range.
