Coba jelasin Tumbuhan yang tidak disukai dari Tanaman penutup tanah dong

Tanaman penutup tanah diperlukan oleh beberapa perkebunan terutama pada perkebunan Kelapa Sawit. Pada awal pembukaan lahan makan dilakukan penanaman pokok kelapa sawit dan saat ini lah peran dari tanaman penutup tanah  sangat diperlukan untuk melindungi tanaman baru dari serangan tumbuhan liar yang tidak diinginkan.

Banyak tumbuhan yang termasuk dalam tumbuhan pengganggu atau tidak disukai yang dapat berfungsi sebagai penutup tanah atau pelindung tanah terhadap ancaman erosi. Tumbuh-tumbuhan itu tidak disukai karena sifat-sifatnya yang merugikan tanaman pokok dan sulit diberantas atau dibersihkan dari lahan usaha pertanian: Imperata cylindrica, Panicum repens (lampuyangan), Leersia hexandra (kalamento), Saccharum spontaneum (gelagah), Anastrophus compressus dan Paspalum compressum (tumput pahit).
