“…The test results validate the soil cutting theory that tools with a larger working width produce larger cutting resistance [35]. Darmora and Pandey [39], Hasimu and Chen [29], and Ahmad et al [28] found the same results when they tested different types of furrow openers.…”

Conservation agriculture is an important measure promoting sustainable agriculture in northeast China. Coulters in the conservation agriculture system are used to cut the excessive residue in strips, loosen soils, and create good seedbeds. Information on the performance of coulters worked in a field with or without corn residue coverage is lacking in the literature. In this study, five coulters were tested in two field conditions at three working velocities to compare their performance. The five coulters were four types of fluted coulters (8 W, 13 W, 18 W, and 25 W) and one notched-flat coulter (NF); the two field conditions were whole residue plots (WR) and no residue plots(NR), and the three working velocities were 8 km/h (V1), 10 km/h (V2), and 12 km/h (V3). All of the tests were tested at a tillage depth of 80 mm. The results showed that the maximum furrow width (Wf), furrow disturbance area (A), and residue coverage change (C) were significantly affected by the working velocity and coulter type, while the cutting force (F) and skid rate (S) were significantly affected by the residue coverage, working velocity, and coulter type. The NF was found to have the smallest furrow profile, residue coverage change, and cutting force, as well as the largest skid rate. Among the fluted coulters, as the wavenumber rose, the cutting force, furrow width, and furrow disturbance area all gradually decreased, while the skid rate and residue coverage change were gradually enhanced. The straw residual intensified the cutting force and reduced the skid rate, which changed by 11.6% and 20.9%, respectively. As the working velocity rose from 8 km/h to 12 km/h, the furrow width, furrow disturbance area, residue coverage change, cutting force, and skid rate increased by 26.5%, 16.5%, 44.6%, 8.2%, and 22.7%, respectively. The results reveal that the flat coulter and large-wavenumber fluted coulters (18 W and 25 W) have less cutting force and are more beneficial for cutting straw residue in residue coverage fields, while the small-wavenumber fluted coulters (8 W and 13 W) are suitable for loosening soil and constructing seedbeds. The cutting force has significant effects on the performance of cutting straw residue, loosening soils, and creating seedbeds.

“…Crop Science © 2020 Crop Science Society of America The development of seed drill technology and placement of seed directly in the soil has led to the practice of applying all the seed and fertilizer in a single field pass. Different seed drill openers have been designed with different capabilities of fertilizer placement (Ahmad, Weimin, Qishuo, Hussain, & Jabran, 2015;Aikins et al, 2018;Swanepoel et al, 2018). With tine openers, fertilizer is placed deeper than the seed, whereas disc openers generally place seed and fertilizer at the same depth.…”

Canola is injured by in‐row nitrogen placement associated with disc openers, but not by tine openers

Seed drills are used in no‐tillage systems to place seed directly in soil. Various furrow openers exist, each with unique seed and fertilizer placement characteristics, particularly positioning of fertilizer in relation to the position of the seed. Seedling damage may occur if seed and fertilizer placement is not appropriate for the particular crop. Canola (Brassica napus L.) seed is small, resulting in seedlings susceptible to injury by fertilizers. A study was conducted to evaluate the effect of in‐row N placement with a seed drill fitted with single‐ and double‐chute tine openers, and disc openers. The study was performed in a Mediterranean‐type climate region in South Africa over 2 yr. Plant establishment was reduced by 48% when canola was established with disc openers with no separation between N and the seed (P < .05). Tine openers were most successful in establishing an acceptable plant population, as well as ensuring high biomass production throughout the season, leading to a high leaf area index. Although no yield differences (P > .05) were observed between openers, it was concluded that the application of N in the band at the same position as the seed is a risk. Tine openers, either with a single or double seed chute, that separate seed and fertilizer resulted in the best canola performance.

The high production costs in agriculture have guiding the adoption of farming systems and new management techniques as well as the sizing of agricultural machinery. In this regard, planning entails knowledge on the efficiency according to the energy requirements parameters, so the farmer shall consider the characteristics of the soil on which the implement operates. The performance assessment of sowing-fertilize machines shows the effect of some variables on the draft requirement, so the experimental conditions, which might lead to different outcomes of implement operation, must be regarded. Therefore, it is necessary obtain metanalytical estimates to integrate the results available in the literature. Grounded on systematic review, this study aimed to model the draft imposed by sowing-fertilizing machines considering fixed effects, mainly soil characteristics, and random effects associated to the selected experiments. It was found that the best models according to information criteria may not always meet the assumptions as normality of the distribution of residuals and homoscedasticity. The variables such as bulk density of soil, stubble conditions, depth of fertilizer placement, and speed could accurately explain the draft requirement with mean squared deviation of 2.93 whereas the referred evaluator for the ASABE standard was 63.51. Forthcoming works may analyze the repeatability of the models considering different seeders under diverse configurations and operation conditions
