From an economic viewpoint farms with a surplus of manure should use as much manure as (legally and agriculturally) possible. Overdoses of nutrients are less desirable from an environmental viewpoint.作者: 聯(lián)邦 時(shí)間: 2025-3-22 07:31 作者: graphy 時(shí)間: 2025-3-22 08:55 作者: 輕打 時(shí)間: 2025-3-22 15:40 作者: 重力 時(shí)間: 2025-3-22 19:53
