The phrase "at tillage" is not correct and does not convey a clear meaning in written English.
It seems to be an attempt to refer to agricultural practices, but it lacks context and clarity.
Example: "The farmers were busy at tillage, preparing the fields for planting."
Alternatives: "during cultivation" or "in farming activities".
Working out the equation of surface of the mouldboard and using the analytical dependencies of the relative and absolute motion trajectories of the blade movement the mathematical models are received describing the patterns of motion of soil particles, at tillage with hulls with mouldboards of ripping type.
However, intermittent tillage every 4 5 years for replanting poses limitations to carbon sequestration because a 12 year experiment which was sampled 1 year after replanting did not show any carbon sequestration, suggesting that all carbon stored between planting and replanting was lost at tillage.
For this particular mouldboard plough, maximum downslope soil transport took place at a tillage direction ca. 70° and not when tillage was conducted along the steepest slope direction (0°).
The results showed that the most pikes m−2, grains/spike, 1000-grain weigraingrain yield, and N use efficiency (NUE) were obtained at zero tillage, straw retained and 4 splits application of total N (i.e., at sowing 20, 45 and 70 d after sowing).
Building off this and other farmer experience, research at Cornell University and University of Maine has been looking at the tillage-like benefits tarps provide and what kind of "legacy" they leave to subsequent crops.
Next year we'll look at these biofungicides in combination with reduced tillage at one site.
Soil WEOC was TR < NT at Breton but was not affected by tillage at Ellerslie.
At a chisel tillage site, drilled soybean planted at 170,000 seeds/acre yielded about 4% more than 30-inch soybean at 130,000 seeds/acre.
At the conservation tillage plot, below 20 cm soil depth, macropore density was greater than at the conventionally tilled plot.
At the chisel tillage site, drilled beans yielded only about 4% greater than beans in 30-inch rows, if planted at 170,000 seeds/acre (Table 1).
Drilled soybeans in 7.5 inch rows averaged 69% early stand establishment (103,645/150,000) compared to about 81% in 30 inch rows at the chisel tillage site.
