If biomass is regularly leaving the land (e.g., sales of fruit, biochar, compost) will the soil get depleted over time? Plants take some building blocks from the air (carbon, nitrogen), but others might get leave the farm with land with the sold produce (e.g., Phosphorus) .

I am wondering if there are any studies on this.
