Impact of tobacco management practices on soil, water and nutrients losses in steeplands with shallow soil

Best tillage practices for eucalyptus growth and productivity: A review on the Brazilian experience

“…However, if used improperly, tillage techniques can physically, chemically and biologically degrade the soil in a few years of use, reducing its productivity potential (Gonçalves et al, 2000). Since soil tillage changes physical, hydraulic and mechanical properties of the soil and, consequently, crop development and productivity (Klein et al, 2009;Fasinmirin and Reichert, 2011; Reichert et al, 2019Reichert et al, , 2020aAwe et al, 2020), soil physical environment is decisive for the initial growth of eucalyptus (França et al, 2021;Reichert et al, 2021b). Initial development is defined as the period between planting and the closing of the canopy, which occurs between the ages of one and two years for plantations with a spacing of 6 to 9 m² (Stape et al, 2002).…”

Adoption intensity of a standardized technical system: The higher the better?—Evidence from China

“…The average altitude of tobacco planting areas (typical mountainous areas) in Chongqing is 800-1,400 m, and tobacco is one of the few cash crops in these areas similar to that in Indonesia and the Philippines (Appau et al, 2019). Because of the long-term planting of tobacco in Chongqing, it is generally difficult to realize fallow tillage and crop rotation, resulting in continuous land degradation, serious ecological environmental pollution, frequent occurrence of pests and diseases, increasing production risks, and increasing planting costs, which restrict high and stable yields as well as quality improvements in tobacco production (Chen et al, 2018;Reichert et al, 2019). This seriously impacts the income of tobacco farmers.…”

Tributary contributions to sediment deposited in the Jacuí Delta, Southern Brazil

“…The lack of land use planning and the limited implementation of soil conservation measures result in a large contribution of sediment from the cropland areas (Tiecher et al, 2017(Tiecher et al, , 2015. In addition, the intensive use of fertilizers and pesticides has resulted in the contamination of river sediment with phosphorus (Bender et al, 2018;Reichert et al, 2019;Tiecher et al, 2019;Zafar et al, 2017Zafar et al, , 2016, various agrochemicals (de Castro Lima et al, 2020;Fernandes et al, 2019) and veterinary drugs (Camotti Bastos et al, 2018).…”
