The development of methods in digital soil mapping has been an activity that's growing substantially in recent decades. The DSM is quickly evolving from the research stage to map production at various scales covering countries, regions and river basins (Lagacherie and McBratney, 2007). The prediction of classes and properties of soils in digital mapping is based on the relationship between the factors and soil formation processes. Chemical knowledge of soil attributes is a factor of great relevance for rational use of limes and fertilizers. This work’s study area are the regions: north, northwest and Serrana do Estado do Rio de Janeiro. |

The objective was to develop efficient substrates, with increasing proportions of biochar derived from anaerobic sewage sludge (ASS-biochar) and regionally available raw materials, to produce tobacco seedlings (Nicotiana tabacum) in floating systems. Physical, hydraulic and chemical variables and the effects on tobacco plants were evaluated through an indoor experiment with seedling production. The experiment was conducted on trays in a floating hydroponic system in a randomized block design with four replications and eight plants per plot. The ASS-biochar showed environmental safety and agronomic efficiency in substrate composition, in particular with 50% to 90% ASS-biochar in the formulation. The best formulations positively affected the growth-related variables, showing similar or superior performance to the three commercial substrates (references). The ideal ranges of the substrate characteristics were: dry density: 420?520 kg m?3; total porosity: 60?75%; aeration space: 25?35%; easily available water: 9?12%; water buffering capacity: 3?5%; available water: 12?15%; remaining water: 20?25%; pH: 6.0?6.5; electrical conductivity: 1.4?2.3 mS cm?1. The development of substrates considering ASS-biochar, regional raw materials and ideal physical-chemical properties would prevent environmental pollution by generating value-added products to improve tobacco seedlings and expand the productivity and quality of tobacco worldwide. |
