“…In addition to reducing grain yield, late sowing increases the risk of frost damage. Therefore, using other crops to improve the production system is an appropriate strategy for this region (Garcia et al, 2013;Lima et al, 2015). Sans & Guimarães (2008) reported that when sowing is postponed until after mid-February, the negative effects BRS 284 and BRS 1010;□, BRS 284 and DKB 390;Δ, BRS 360 RR, and BRS 1010;and ■, BRS 360 RR and DKB 390.…”

“…Stallings et al (2017) reported higher C:N ratio that led to greater immobilization with June and July planting of sunn hemp, and lower C:N ratio with May planting. At the 0 to 5-cm layer, increased soil nitrogen was recorded with cover grasses and sunn hemp compared to fallow (Garcia et al, 2013).…”

Crops like corn and soybean occupy vast area in the Midwest, USA. When land is left fallow after the harvest of these crops, a number of degradation factors operate and bring about soil erosion, nutrient loss, decreased soil organic carbon, reduced biological activity and increase in weed biomass. Integrating cover crops (CCs) into this system would build benefits that the very system lacks. There are various CCs available, but leguminous CCs allows for reduced application of fertilizer nitrogen and builds the soil fixed atmospheric nitrogen. Winter CCs are restricted in the Midwest because of the short planting window which greatly minimizes the biomass accumulation. Warm season CCs would serve well here. Sunn hemp is one such tropical CC that grows well in temperate conditions too, without producing seeds. It comes with many benefits -including decreased soil erosion, improved soil organic carbon, increase in soil fixed nitrogen, higher biomass that adds organic matter and N to the soil, reduced weed density and weed biomass. The timing and method of termination influences the residue management. Going by the benefits it adds, sunn hemp is a viable warm season CC that can be grown in the Midwest and has great potential in fallows, prevented plant acres, areas of crop failure (planted and failed) and also in areas after the harvest of the short season small grains or processing crops. However, intensive research on sunn hemp is needed in the Midwest which is discussed.

“…However, the soil chiseling effects might disappear after, approximately, two years of operation, depending on soil texture, climate, and cropping system (Evans et al, 1996;Colonego and Rosolem, 2010;Nunes et al, 2014). On other hand, increase of soil organic carbon content is a slow process (Six et al, 2002;Abdollahi et al, 2014), and the positive effects due to plant species growth on soil aggregates under NT are expected to occur in the long-term (Garcia et al, 2013).…”

“…However, the increases of aeration and temperature in the topsoil layer (at around 0-0.25 m), due to soil mechanical chiseling, might accelerate organic carbon mineralization and, consequently, influence soil aggregation state (Fabrizzi et al, 2009). Soil biological and biochemical properties respond quickly to changes produced by soil management (Visser and Parkinson, 1992;Trasar-Cepeda et al, 2008;Garcia et al, 2013). According to Melero et al (2011), mechanical practice to mitigate soil compaction under NT has a negative effect on organic carbon and on enzymatic activities, producing, in short-term, losses in organic matter, reducing soil biochemical quality.…”
