“…For the treatment with the sprinkler system, irrigations were more frequent and at depths ranging from 8-16 mm, maintaining θ to meet the crop water requirements, which results in better soil aeration. A sustainable irrigation system and soil management practices are required to successfully implement soybean in wetlands (Bueno et al, 2020) and provide irrigation and satisfactory drainage.…”

“…It is noteworthy that this equipment, particularly the subsoiler, will show the highest efficiency (reduction in PR) when operations are performed with the soil in a friable state. However, because of the features of this environment, like low water infiltration capacity, the lowland regions are left undisturbed for long durations under highly humid conditions (BUENO et al, 2020), a state that is below the ideal for performing these operations, which results in decreased windows of time for preparation.…”

The present study assessed soil preparation in terms of the advantages it provides in lowering the physical obstacles and their influence on soybean cultivation, with reference to its establishment, development and yield, apart from quantification of the energy demand for tractor performance. The experiments were performed in the field adopting the randomized block design with a two-factor scheme (6x2). Factor A included a variety of soil preparations performed during the off-season of the soybean crop. Sowing was accomplished using the same fertilizer deposition mechanism only, and the areas having no soil preparation done were sown using various other fertilizer deposition mechanisms from the seeder, namely: (A1) sowing without soil preparation (SSPS)+double disc in the seeder (DD); (A2) SSPS+turbo disc (DT); (A3) SSPS+furrowing rod (HS); (A4) plow harrow+DD; (A5) scarified+DD and (A6) subsoiled+DD. Soil preparations before sowing were done on days 52 and 98 days, respectively, during the first and second harvests. Factor B included two soybean cultivars, namely: (B1) Nidera 6601 and (B2) Brasmax Valente. No interaction was observed between the factors investigated. While the scarification+DD showed the need for higher fuel consumption, the results were increased productivity. For the seeder-linked mechanisms, the HS gives more extensive root development of the plants and grain yield. On the contrary, while DD and DT show the combination of the highest operational capacity and lower fuel usage, this is related to lower grain yield.

“…In the ridge-system, there are generally three distinct environments in terms of irrigation conditions. In the upper portion, the soil is humid, a more oxidized and in the intermediate portion, the soil is already saturated (Bueno et al, 2020). At the end of the ridge-system, the bottom portion is where water accumulates, the soil is ooded and soil conditions are reduced, which can favor higher CH 4 emissions (Massey et al, 2014).…”

Flood irrigated rice, in addition to using large volumes of water, is one of the main causes (~30%) of methane (CH4) emissions from agriculture. New cultivation technologies in lowlands, such as ridge-furrow, enable the use of a smaller volume of water in rice cultivation compared to traditional flood irrigation and higher soil oxidation, which can impact the emission of CH4 and nitrous oxide (N2O). The expansion of the use of the ridge-furrow system in southern Brazil occurs because it has been one of the systems responsible for the expansion of alternative crops, such as soybean and corn in rotation with rice. The ridge-furrow promotes adequate drainage of the soil surface and irrigation of crops, minimizing damage from excess and deficit water in lowlands. Thus, the objective of the work was to evaluate the emission of CH4, N2O, partial global warming potential (pGWP) and rice grain yield in a ridge-furrow system in rotation with soybean. The trial was carried under field conditions at the Ricetec Experimental Station, in the 2020/21 and 2021/22 crop seasons in Capão do Leão, Southern Brazil, taking advantage of the infrastructure of ridge-furrow established for soybean in rotation in the previous season. Was used an XP117 RiceTec rice hybrid with a 130-day cycle. The treatments consisted of different portions of the furrow: upper (wet soil); intermediate (saturated soil) and bottom portion (flooded soil). Rice cultivation in the ridge-furrow system reduced CH4 emissions by 34% and partial global warming potential by 30%. Rice grain yield levels remained high in the ridge-furrow system. Thus, the ridge-furrow irrigation contributes to increasing the sustainability of rice production as it enables a significant reduction in CH4 emissions and a more efficient in the use of water.
