Question

Quizplus · Accepted Answer

Oxisols and Ultisols are naturally poor in fertility and have low levels of essential plant nutrients. They also have high levels of acidity and are able to sustain crops for only several years before becoming unproductive. Mollisols have higher fertility levels and are able to sustain crops for longer periods of time, while Alfisols and Aridisols have moderate fertility levels and can sustain crops for longer periods of time as well. Histosols are organic soils that are formed from decomposing plant materials and are often highly fertile.
