Bulk vs Bags

O Cálculo

Volume = área (m²) × espessura (m). 50 m² a 7 cm: 3,5 m³. Espessura ideal: 5-7 cm. Mais de 10 cm sufoca raízes. A granel: R$50-100/m³. Em sacos: R$150-250/m³.

Tipos no Brasil

Casca de pinus: R$50-100/m³ (mais comum). Palha de café: R$30-60/m³ (excelente para hortas). Casca de eucalipto: R$40-80/m³. Pedra britada: R$80-150/m³ (permanente).
