Strip tillage and crop residue retention decrease the size but increase the diversity of the weed seed bank under intensive rice-based crop rotations in Bangladesh por Hossain, Mohammad Mobarak, Begum, Mahfuza, Hashem, Abul, Rahman, Md. Moshiur, Ahmed, Sharif, Hassan, Montaser M., Javed, Talha, Shabbir, Rubab, Hadifa, Adel, EL Sabagh, Ayman, Bell, Richard W.

Impact of conservation tillage in rice–based cropping systems on soil aggregation, carbon pools and nutrients por Nandan, Rajiv, Singh, Vikram, Singh, Sati Shankar, Kumar, Virender, Hazra, Kali Krishna, Nath, Chaitanya Prasad, Poonia, Shishpal, Malik, Ram Kanwar, Bhattacharyya, Ranjan, McDonald, Andrew

“…Retention of crop residue increased (p < 0.05) TOC (12%) and soil available nutrients mainly available–P (16%), followed by available–K (12%), DTPA–extractable Zn (11%), and available–S (6%) over residue removal treatment. The constructive changes in soil properties following conservation tillage and crop residue retention led to increased crop productivity over conventional CTTPR–CT. …”
