Corn yields up north have climbed faster than soybean yields, ... John Nelson follows vertical tillage on continuous-corn ground with a Case IH 870 disk ripper, equipped with shanks spaced at 24 in. The 2.6% mean yield increase over 5 years with OT for corn and grain sorghum was not statistically significant. When it came to returns, conventional tillage led with $456.52 per acre, followed by strip-till, no-till and vertical tillage a full $18.70 per acre less than conventional. Vertical tillage is one of the conservation tillage options for managing corn residue prior to planting soybeans. His fall tillage operations leave about 40% residue cover for the winter. “Vertical tillage doesn’t work against no-till, it works with no-till,” says Tom Evans of Great Plains Mfg. In the soybean tillage study, yields for all four tillage systems were within 3.2 bu/acre of each other, with conventional and strip-till yielding the highest. The data of soybean grain P were recorded since the year of 2003. Soybean yield is used as the measure of tillage and seeding rate effects. Vertical tillage: 2009 soybean yield • NT yield: 65.9 • VT yield: 67.1 • Not significant at p<0.05 • Interest in vertical tillage was gaining momentum, so asked … Till-Tech Systems of Straffordville, Ont., makes a vertical tillage … Soybean yield was not affected by tillage at any of the farms during the four growing seasons, except on the farm with sandy soils near Barney in 2018 (Table 1). and a harrow. Vertical Tillage Speeds Planting, Doesn’t Increase Soybean Yields | No-Till Farmer This article summarizes the results from five Michigan on-farm research trials evaluating the effects that two different vertical tillage implements had on soybean yields. This is particularly the case for soybean yields, as well as rotated corn systems.
Yield differences from soil tillage are more often the exception rather than the norm. Vertical tillage tools can be valuable for sizing and anchoring no-till residue and improving seedbed conditions for planting, according to a recent study by Michigan State University Extension. Impacts on plant population, growth and yields The trends in soil moisture and temperatures did not cause any differences in soybean or corn plant populations, growth, or yields. Vertical Tillage Speeds Planting, Doesn’t Increase Soybean Yields. ... Vertical tillage tools can be valuable for sizing and anchoring no-till residue and improving seedbed conditions for planting, according to a recent study by Michigan State University Extension. Salford, in southern Ontario, which has been building a vertical tillage toolbar for corn and soybean growers for years, is trying to crack into the Prairie market.
In the eastern Nebraska studies, soybean in rotation with corn or grain sorghum had a 3.6% mean yield increase during the 5-year study due to OT with a greater yield benefit following OT with a mini-moldboard plow (Figure 1). Most popular in corn and soybean growing regions, vertical tillage may work well on some soils and for certain applications, but any suggestion that widespread adaptation of vertical tillage is of value for grain and oilseed production may be premature, they say. Dealers who haven’t picked up on the push for “soil health” in the last few years haven’t been paying enough attention. This study was designed as a randomized complete block with four replications of each treatment. When it came to returns, conventional tillage led with $456.52 per acre, followed by strip-till, no-till and vertical tillage a …
