Short summary
Straw mulching is not always combined with no-till systems during conservation tillage. We explored the effects of long-term straw mulching on soil attributes with soil depths under a no-till system. Compared to straw removal, straw mulching had various effects on soil properties at different depths, the biggest difference occurring at the topsoil depth. Overall, straw mulch is highly recommended for use under the no-till system because of its benefits to soil fertility and bacterial abundance.
