“…Soil textural analyses (British Standard, 1990) for the bulked 0-to 200-mm layer were: 67% sand, 13% clay, and 20% silt for Avenue field, and 79% sand, 11% clay, and 10% silt for Chippies field, respectively. Soil bulk density (1.34 g cm -3 , Antille et al, 2013a) was representative for this depth of this soil series. Moisture content at field capacity (0.05 bar, Hall et al, 1977) was 26.6 and 23.4% (w w -1 ) for Avenue and Chippies fields, respectively.…”

Field‐Scale Evaluation of Biosolids‐Derived Organomineral Fertilizers Applied to Winter Wheat in England

et al. 2017

Field-scale experiments in four crop seasons established the agronomic performance of biosolids-derived organomineral fertilizers (OMF) for winter wheat (Triticum aestivum L.) production in England. Two OMF formulations (OMF 10 10:4:4 and OMF 15 15:4:4) were compared with urea and biosolids granules (≈5:6:0.2) to determine crop responses and fertilizer eff ects on soil chemical properties. Fertilizers were applied at N rates between 0 and 250 kg ha -1 at regular increments of 50 kg ha -1 N. Average grain yields with OMF 10 and OMF 15 were higher than with biosolids granules, but lower than with urea (P < 0.05). Th e optimum N application rates, and corresponding grain yields, were 245 and 7900 kg ha -1 for biosolids, 257 and 9100 kg ha -1 for OMF 10 , 249 and 9500 kg ha -1 for OMF 15 , and 225 and 10350 kg ha -1 for urea, respectively. Diff erences in grain yield between fertilizer treatments were explained by diff erences in yield components, particularly number of grains and thousand-grain-weight. Grain-N recoveries were 31% for biosolids, ≈40% for OMF, and 52% for urea. Organomineral fertilizers-induced changes in soil extractable P and soil P Index were not signifi cant. Th us, application of OMF replenished P offt ake by the crop and therefore supported the choice of the proposed OMF formulations. By contrast, extractable P increased in biosolids and decreased in urea-treated soils, respectively. Heavy metals in soil were unaff ected by fertilizer treatment and lower than permissible limit values. Th e use of OMF for winter wheat production appears to be a sustainable approach to recycling biosolids to land.

“…A total of 9 passes with the tractor were required to achieve ≈30% higher soil bulk density in the non-CTF compared with the CTF treatment. This relative difference in soil compaction was considered to be appropriate based related studies (e.g., Radford et al, 2001;Antille et al, 2013;Godwin et al, 2015) albeit on different soils. Soil moisture at the time of traffic was 18% and 20.5% (w/w) at the 0-200 mm and 200-400 mm depth intervals, respectively.…”

Controlled traffic farming (CTF) is a mechanization system that confines all load-bearing wheels to permanent traffic lanes, thus optimizing productivity of non-compacted crop beds for given energy, fertilizer and water inputs. This study investigated the agronomic and economic performance of winter wheat (Triticum aestivum L.) grown in compacted and non-compacted soils to represent the conditions of non-CTF and CTF systems, respectively. Yield-to-nitrogen (N) responses were obtained by applying urea (46% N), urea treated with 3,4-dimethyl pyrazole phosphate (DMPP), commercially known as ENTEC ® urea (46% N), and urea ammonium nitrate (solution, 30% N) at rates between 0 (control) and 300 kg ha-1 N at regular increments of 100 kg ha-1 N. The results showed that the CTF system increased grain yield, total aboveground biomass, and harvest index by 12%, 9%, and 4%, respectively compared to the crop grown under the non-CTF system (P<0.05). Overall, the agronomic efficiency was approximately 35% higher in CTF compared with non-CTF (≈4 vs. 3 kg kg-1 , respectively). Nitrogen use efficiency (NUE) was approximately 50% higher in CTF compared with non-CTF; however, there was not fertilizer type effect on NUE. On average, the optimal economic nitrogen application rates and corresponding grain yields were 122 kg ha-1 and 3337 kg ha-1 , and 175 and 3150 kg ha-1 in the CTF and non-CTF systems, respectively. This work demonstrated that significant improvements in fertilizer-N recoveries may not be realized with enhanced nitrogen formulations alone and that avoidance of (random) traffic compaction is a prerequisite for improved fertilizer use efficiency.

“…Self-amelioration of soils affected by compaction occurs slowly from the surface downward; however, the rate of amelioration decreases with increase in soil depth (Dexter, 1991;Chinn and Pillai, 2008;. Traffic impacts are persistent (Alakukku, 1996;Radford et al, 2007), meaning that all soils in non-CTF systems are affected by some degree of compaction at depths greater than 100 mm (Ansorge and Godwin, 2007;Antille et al, 2013a), which reduces water infiltration and hydraulic conductivity, increases the risk of waterlogging, and creates favorable conditions for enhanced N 2 O emissions.…”

The drive toward adoption of conservation agriculture to reduce costs and increase production sustainably causes concern due to the potentially negative effects of increased soil compaction. Soil compaction reduces aeration, water infiltration, and saturated hydraulic conductivity and increases the risk of waterlogging. Controlled traffic farming (CTF) is a system in which: (1) all machinery has the same or modular working and track width so that field traffic can be confined to the least possible area of permanent traffic lanes, (2) all machinery is capable of precise guidance along those permanent traffic lanes, and (3) the layout of the permanent traffic lanes is designed to optimize surface drainage and logistics. Without CTF, varying equipment operating and track widths translate into random traffic patterns, which can cover up to 85% of the cultivated field area each time a crop is produced. Nitrous oxide (N 2 O) is the greatest contributor to agriculture's greenhouse gas (GHG) emissions from cropping, and research suggests that its production increases significantly under conditions of high (>60%) water-filled porosity when nitrate (mainly from fertilizer N) and carbon (usually from crop residues) are available. Self-amelioration of soils affected by compaction occurs slowly from the surface downward; however, the rate of amelioration decreases with increase in depth. Consequently, all soils in non-CTF systems in mechanized agriculture are prone to some degree of compaction, which compromises water infiltration, increases the frequency and duration of waterlogged conditions, reduces gaseous exchange between soil and the atmosphere, inhibits root penetration and exploitation of nutrients and water in the subsoil, and enhances N 2 O emissions. Adoption of CTF increases soil porosity in the range of 5% to 70%, water infiltration by a factor of 4, and saturated hydraulic conductivity by a factor of 2. The greater cropping opportunity and enhanced crop growth for given fertilizer and rainfall inputs offered by CTF, coupled with no-tillage, provide potential for enhanced soil carbon sequestration. Reduced need and intensity of tillage, where compaction is avoided, also helps protect soil organic matter in stable aggregates, which may otherwise be exposed and oxidized. There is both circumstantial and direct evidence to suggest that improved soil structural conditions and aeration offered by CTF can reduce N 2 O emissions by 20% to 50% compared with non-CTF. It is not compaction per se that increases the risk of N 2 O emissions but rather the increased risk of waterlogging and increase in water-filled pore space. There may be an elevated risk of GHG emissions from the relatively small area of permanent traffic lanes (typically <20% of total cultivated area) if these are not managed appropriately. Quantification of the benefits of compaction avoidance in terms of GHG emissions may be possible through the use of well-developed models. Keywords.
