High quality residues from cover crops favor changes in microbial community and enhance C and N sequestration

Effect of white mustard cover crop residue, soil chemical fumigation andTrichodermaspp. root treatment on black‐foot disease control in grapevine

“…The use of Brassica cover crops is associated with changes in the soil microbiome, and has sometimes been found to increase BCA populations in the rhizosphere . For instance, Montfort et al .…”

“…The use of Brassica cover crops is associated with changes in the soil microbiome, 44,45 and has sometimes been found to increase BCA populations in the rhizosphere. 46 For instance, Montfort et al 47 reported that T. atroviride was relatively unaffected by mustard biofumigation under controlled conditions, which agreed with the findings of Galletti et al, 48 who reported that in vitro Brassica carinata seed meal trial combined with Trichoderma spp.…”

The legacy of cover crops on the soil habitat and ecosystem services in a heavy clay, minimum tillage rotation

“…Cover crops have been highlighted as a method to reduce nutrient losses (Cooper et al, ), increase soil organic carbon (Ladoni, Basir, Robertson, & Kravchenko, ), and change fauna abundance and diversity (Blubaugh, Hagler, Machtley, & Kaplan, ; Frasier et al, ) as well as reduce anthropogenic inputs (Wittwer, Dorn, Jossi, & Heijden, ). However, proving to the average farmer their usefulness has not been achieved to date (Bouma, ).…”

“…Brassicas, such as radish ( Raphanus sativus ), mustards, and turnips, also provide a good ground cover and have been found to reduce nitrate leaching due to the deep rooting system which is able to scavenge more nutrients from depth (Cooper et al, ). Legumes, including vetch ( Vicia sativa ), crimson and berseem clover ( Trifolium incarnatum ; T. alexandrinum ), and lucerne ( Medicago sativa ), fix nitrogen from the atmosphere and have been found to improve litter quality (due to their lower C:N ratios) (Frasier, Quiroga, & Noellemeyer, ) leading to increases in soil organism biodiversity (Crotty, Fychan, Scullion, Sanderson, & Marley, ) and mineralization (Frasier et al, ). While “other” cover crops include plants like buckwheat ( Fagopyrum esculentum ) and phacelia ( Phacelia tanacetifolia ), these are from different plant families taxonomically to other crops in a normal arable rotation and can therefore provide a disease break as well as other benefits.…”

Blending polymer-sulfur coated and NBPT-treated urea to improve nitrogen use efficiency and grain yield in corn production systems

“…Other simple but key management practices should not be overlooked. It is known that the inclusion of cover crops in the cropping system improves NUE (Fontes et al, 2017), in addition to the ecosystem services they provide (Frasier et al, 2016). Moreover, adequate soil correction , use of appropriate crop rotations, adoption of conservation tillage, correct control of insects, diseases, and weeds, all are important crop management strategies that help improving NRE .…”
