Agro-ecological functions of crop residues under conservation agriculture. A review

Abstract: Conservation agriculture, which is based on minimum tillage, permanent soil cover and crop rotations, has widely been promoted as a practice to maintain or improve soil quality and enhance crop productivity. To a large extent, the beneficial effects of conservation agriculture are expected to be provided by permanent soil cover with crop residues. Surface crop residues play an important role for crop growth through their benefits on soil-related structural components and processes in the agro-ecosystem, referr… Show more

“…Working in a semi-arid region that receives about 580 mm of rainfall per year, Choudhary et al [7] showed that water infiltration and retention increased significantly with 2 t ha −1 of crop residue. Similarly, research conducted by Swella et al [8], Nichols et al [9], and Ranaivoson et al [10] suggested 2 t ha −1 as the minimum threshold for improving water infiltration and retention, and also the ideal level for reducing soil loss and weed infestation.…”

“…Mulch management is essential for weed suppression as it depends both on the features of crop residues and on the targeted weeds to suppress (Ranaivoson et al, 2017). The difficulty is to find a service crop that efficiently competes with winter weeds and produces enough mulch in summer to impede the emergence of summer weeds (Fourie, 2010).…”

“…In addressing weed control challenges, scientific studies have provided evidence that minimum and no-tillage induce shifts of weed population particularly towards perennial weeds, thus creating a long-lasting weed problem [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Moreover, annual weeds such as Kochia (Kochia scoparia (L.) Schrad.)…”
