The soil in the forest is often fertile and support plenty of plant without fertilizers why?
Answers
Answer:
Some forests such as tropical forests are, in fact, quite depleted in nutrients, mainly because of heavy rain. Nutrients are ‘recycled’ in most woods through leaf drop, dead organisms, nitrofying bacteria and urine/ faeces. Possibly there is some contribution from electrical storms producing nitrogen compounds from the atmosphere. Plants adapt and make the best of their situation so they may be economical with sparse nutrients and ‘attract’ wildlife such as birds, squirrels, deer etc that may add to the local nutrition. It has been suggested that some areas of the forest in Canada are fertilized by bears which catch salmon and carry them into the woods, only devour the ‘easy meat’ such as the egg roe and leave the rest to decompose and fertilize the area. All down to Darwin and his ‘Adaption’ again
