Sorghum seeds were planted in 20 dm3 plastic pots filled with a 3 cm layer of gravel at the bottom, and 15 kg of soil collected from the 0-20 cm layer of a sandy loam textured soil classified by the Embrapa as latosolic Dystrophic Yellow Argissolo, which presented the following characteristics: electrical conductivity of 0.23 dS [m.sup.-1], pH of 5.7; 0.7 [cmol.sub.c] [dm.sup.-3] of Mg; 1.0 cmolc [dm.sup.-3] of Ca; 1.6 [cmol.sub.c] [dm.sup.-3] of H + Al, 0.33 [cmol.sub.c] [dm.sup.-3] of K, 0.07 [cmol.sub.c] [dm.sup.-3] of Na, 84.7% of sand, 13.5% of silt, and 1.8% of clay.
Thus, this study was to investigate the effects of tillage on soil biochemical properties and maize grown in latosolic red soil of Southern China.
The Ferrallisols include four soil great groups: Latosols (main land uses forest and dryland), corresponding to Acrisols in the World Reference Base for Soil Resources by IUSS Working Group WRB (2014); Latosolic Red soils (main land uses forest and dryland), also corresponding to Acrisols (IUSS Working Group WRB 2014); Red soils (main land use forest), corresponding to Cambisols (IUSS Working Group WRB 2014); and Yellow soils (main land use forest), also corresponding to Cambisols (IUSS Working Group WRB 2014).
Latosolic soils are suitable for banana production to be well-drained, deep (over 100 cm), medium texture to clayish, well-structured, permeable, fertile, neutral to slightly acidic pH, no risk of flooding and salinity free (SALOMAO; SIQUEIRA, 2015).
The experiment was seeded in the 2010/2011 crop in the Coodetec--Agricultural Research Center Cooperative in Cascavel, Parana State (Latitude S 24[degrees] 52' 56.9"; Longitude W 53[degrees] 32' 00.4" and altitude 690 m) in Purple Latosolic Distroferric soil.
The increase in electrical conductivity of the soil saturation extract (CEes), caused by the use of solid and liquid waste produced during the processing of cassava as a source of fertilization, was observed when maize was cultivated on latosolic dystrophic Inceptisol located in Minas Gerais, Brazil, and CEes of 0.80 dS [m.sup.-1] was measured when the highest dose of residue was applied [24].
In the study area, three soil types predominate: Ferric Red Latosols, derived from basalt and occurring with lower proportion only in the flat top areas in the basin; Distroferric Red Nitosols, with latosolic characteristics, which develop in areas with average slopes; and the Fluvic Neosols with alluvial features (hydromorphic), which are found near some drainage channels.
The latosolic "tierra colorada" soils that cover more than 80 percent of Misiones produce good manioc harvests.
Thus, it is likely that a true latosolic, microgranular structure began to develop in the late Cretaceous, reaching a climax from the mid-Tertiary onwards.
According to the Brazilian Soil Classification System (SANTOS et al., 2006), the experiments were conducted on a Typical Eutroferric Red Nitosol with a moderate A horizon and clayey texture, Typical Eutroferric Red Latosol with a moderate A horizon and very clayey texture, Eutroferric Latosolic Red Nitosol with a moderate A horizon and very clayey texture, and Typical Dystrophic Red Latosol with a moderate A horizon and medium texture for the municipalities of Arapongas, Cambe, Londrina and Paranavai, respectively.
These soils were ascribed to Latosols based on field observations, namely the presence of a latosolic horizon (similar to the Ferralic horizon; 1USS Working Group WRB 2006), namely a subsurface horizon resulting from a long and intense weathering in which the clay fraction is dominated by low-activity clays such as kaolinite and iron (Fe) and Al (hydr)oxides), and on some analytical determinations made on the [B.sub.w] horizons (particle size distribution and Si[O.sub.2]/[Al.sub.2][O.sub.3] molecular ratio, Ki and Si[O.sub.2]/ [Al.sub.2][O.sub.3] + [Fe.sub.2][O.sub.3] molecular ratio, Kr) (data not shown).
