It states that only the illegally deforested area of a farm will be prevented from selling soy. In other words, if a 4,000-acre (1,618-hectare) property clears 200 acres (81 hectares) unlawfully, just the output from that specific area is blocked. Specialists warn that such refined monitoring is technically challenging, if not unfeasible. Under the moratorium, property with any post-2008 deforestation is forbidden altogether to sell its crops, regardless of whether the deforestation is legal. Supporters of the new state law have long claimed the moratorium´s 2008 limit is stricter than Brazilian legislation that allows the deforestation of up to 20% of a large rural property in the Amazon.
