On average, crops require about 30 kg ha-' y-' of P in humid regions. In some regions fertilizer and manure are applied in amounts that exceed this. The surplus of P in agricultural areas is about 20-45 kg ha-' y-'. This implies an accumulation of P. The surplus of P estimated from the balance of ag
