Question

Why do you think in a forest soil does not need replenishment by humans

Please please please please help me ​

Answer 1

Answer:

Subtropics sites identified lack of phosphorus available, show that the years after clearcutting of a plantation, the sum of the phosphorus content increases. Year 2 to 4 shows a sharp increase in the undergrowth. 4 to 6 year increases the phosphorus content in the biomass of the plantation. In both periods the content of available soil phosphorus is stable. Then, the rate of replacement of phosphorus is sufficient to meet the demand of the strata above the ground.
