“…Similarly, in an 11‐year study, Messiga et al (2012) found on a clay loam soil that grain yields with no‐till were reduced by 10–25%. The yield “drag” often seen for cereals grown with no tillage on claypan soils, such as with sorghum in this study, is complex and is probably related to many factors, among which may be poor soil drainage (DeFelice et al, 2006; Al‐Kaisi et al, 2015), having a fibrous rather than a tap root system, and responding to possible changes in soil chemical/physical characteristics. However, measured changes in common soil properties in response to tillage treatments were minimal after 20 years (Sweeney, unpublished data, 1983–2002), and more selective and intensive measurements were beyond the scope of this overall experiment.…”

“…This variability is often influenced by location, soil characteristics, and environmental differences. Even though in parts of the central USA, tillage systems can result in similar yields (DeFelice et al, 2006), corn on poorly drained soils often yields less with no‐till than with tillage (DeFelice et al, 2006; Al‐Kaisi et al, 2015; Cook and Trlica, 2016). Even though a similar trend for lower soybean yields with no‐till has been seen on poorly drained soils (DeFelice et al, 2006), there is limited information about the influence of tillage on grain sorghum and soybean grown on claypan soils, especially long term.…”

Crops grown without tillage on claypan soils in the eastern Great Plains often yield less than with tillage, especially cereals that require careful management regarding N fertilization. The objective of this 20‐year study was to determine the response of grain sorghum and soybean in rotation to tillage and N fertilization on a claypan soil in southeastern Kansas.

“…In a 4-yr study conducted by Vetsch and Randall (2002) in Minnesota, there was no significant difference between various tillage systems on corn grain yield following soybean. In a long term study conducted at multiple locations in Iowa, corn yield varied between tilled and no-till systems, especially in the northern region of the state (Al-Kaisi et al, 2015). However, in our study corn yield was consistently greater (mean 3.3%) with the tilled system compared to no-till.…”

“…In our study, there was only a 3.3% lower no-till yield compared to the tilled system. Despite lower corn yields in a no-till system, no-till can be economically competitive due to differences in production costs (Al-Kaisi et al, 2015).…”

Winter cereal rye (Secale cereal L.), a commonly used cover crop in corn (Zea mays L.) systems has potential to scavenge soil NO3-N through a fibrous root system. The objective of this study was to quantify root and shoot biomass, C, and N partitioning in rye cover crop at the time of termination in spring. This was a one-year study conducted at a site with a no-till corn-soybean [Glycine max (L.) Merr.] rotation, rye drilled following grain crop harvest, and three N rates applied to corn (0, 135, and 225 kg N ha-1). Rye root biomass to 60-cm depth following corn and 30-cm depth following soybean was estimated using ingrowth tubes installed in the fall after rye seeding and removed at the time of rye termination in the spring. For rye following corn and soybean, 48 and 62 %, respectively, of the total root biomass was present in the top 15-cm depth. Overall, the shoot biomass, C, and N was significantly greater than for roots, with approximately two times more shoot than root material and only 33-36 % of total plant C and 17-18 % of total plant N in the root biomass. The C:N ratio of root biomass was consistently high (47-52), and at least double the shoot (16-23). With high C, low N, and

“…Although, the technical-agronomic benefits of no-till crop rotation systems are well described in literature (MALÉZIEUX et al, 2009;BERTOL, 2004;MCGILL et al, 1984;VIEIRA;MUZILLI, 1984), studies on the economic advantages resulting from their adoption are incipient (AL-KAISI et al, 2016;AL-KAISI et al, 2015;GRASSINI et al, 2014;GENTRY et al, 2012), particularly in the Brazilian reality (FUENTES-LLANILLO et al, 2018;LEAL et al, 2005;SANTOS et al, 1999) and especially for the region where Caiuá sandstone is predominant. The low adoption of conservationist production systems may be because farmers do not see an economic return with crop rotation, especially in the short term.…”

Economic profitability of crop rotation systems in the Caiuá sandstone area

Even in areas of predominance of Caiuá sandstone, with soils of low natural fertility that are highly susceptible to erosion and degradation processes, farmers have adopted systems with little diversification, because they believe that they provide a greater economic return. However, agricultural practices such as crop rotation can bring agronomic benefits in terms of conservation agriculture, in addition to economic gains, circumventing edaphoclimatic difficulties in the region. In this context, the objective of this study is to verify whether no-till crop rotation systems are economically profitable, in a Caiuá sandstone area in the northwest region of the Brazilian state of Paraná. To this end, an experiment was conducted in the municipality of Umuarama, state of Paraná, in the crop year 2014/15 to 2016/17. The experimental design used random blocks, with four treatments and four repetitions. The treatments consisted of four crop rotation systems, involving wheat, black oats, canola, safflower, rye, crambe, beans, maize, fodder radish, soybean, sorghum, lupin beans, buckwheat, and triticale cultivars. Crop yields, operating costs, income, and net farm income were assessed. From the results, it was reported that the highest income was obtained in the systems that adopted the largest number of winter and summer commercial crops. Only one treatment was profitable, that is, it had a positive net farm income. This scenario may be associated with the fragility of the region’s soil, which having low fertility, requires a high investment in fertilization and liming to ensure adequate production.
