“…The results show that the lowest operational fuel consumption (15.3 L ha −1 ) is associated with the treatment with eight agricultural tractor passes, a compacted traffic line that requires less engine torque, improving energy performance in controlled traffic [44]. In addition, according to Martins et al [45], operational fuel consumption is related to the equipment width and operating speed; so, with more significant passes, there is greater definition to the lanes and less agricultural tractor rolling resistance.…”

Soil compaction between crop rows can increase a machine’s performance by reducing rolling resistance and fuel demand. Controlled Traffic Farm (CTF) stands out among modern techniques for increasing agricultural sustainability because the machines continuously travel along the same path in the field, reducing plant crush and compacting the soil in the traffic line. This study evaluated fuel consumption and CO2 emissions at different CTF intensities in different soil management strategies for soybean crop. The experimental design involved randomized blocks in a split-plot scheme with four replications. The plots constituted the three types of soil management: conventional tillage, no-tillage with straw millet cover, and no-tillage with brachiária straw cover. The subplots constituted for agricultural tractors were passed over in traffic lines (2, 4, and 8 times). We evaluated agricultural tractor fuel consumption, CO2 emissions, and soybean productivity. The straw cover and tractor-pass significantly affected the fuel consumption and greenhouse gas emissions of the soybean cultivation. Fuel consumption and CO2 emissions were reduced due to the machine-pass increase, regardless of soil management. Thus, a CTF reduces rolling resistance and increases crop environmental efficiency. Bare-soil areas increased by 20.8% and 27.9% with respect to fuel consumption, compared to straw-cover systems. Brachiária straw and millet reduce CO2 emissions per hectare by 20% and 28% compared to bare soil. Lower traffic intensities (two passes) showed (13.72%) higher soybean yields (of 4.04 Mg ha−1). Investigating these effects in other types of soil and mechanized operations then becomes essential.

As climate change continues to affect the environment, drought management has become more critical in agri-food production. Farmers are now looking for alternative drought management methods that are easy to apply. In this sense, superabsorbent polymers (SAPs) were proposed as an alternative soil conditioning and drought management tool within this study. To test the efficiency of a developed SAP (Soyl-Gel) in terms of soil conditioning and plant growth promotion with different soil types and extreme drought conditions, long term soil and greenhouse experiments were carried out in at least 4 replicates. The soil conditioning effect was investigated in terms of soil’s moisture content and maximum water retention period, while plant growth was monitored by 4 different growth indicators using wheat as a model plant. Soil conditioning results demonstrated that Soyl-Gel can enhance the maximum moisture content and extend the moisture retention period of sandy soil by 7-fold and 28-fold, respectively, making it similar to arable soil levels. Plant growth indicators demonstrated that shoot dry matter, spike length and grain yield was enhanced up to 24%, 11.6% using different amounts of Soyl-Gel at varying drought conditions. Study set forth and exemplary of superabsorbent polymer use in agriculture and useful in dose adjustment and understanding the drought-dose relationship in these types of polymers.
