“…Traditionally, in the 0-0.2 m soil depth, there was better lime incorporation, but it did not fully reach 0.2-0.4 and 0.4-0.6 m soil layers. Reductions in the potential acidity are usually observed at 0-0.2 and 0.2-0.4 m soil depth and may be directly attributed to the benefits of lime, which reacts soil carbonate anions and HCO 3 -) with soil potential acidity (H + + Al 3+ ) (Okorkov and Okorkova, 2013). At 0.2-0.4 m soil depth the levels of H + + Al 3+ were great for T4 (desiccation-liming-direct planting) in 2010, and for T3 (liming-harrowing-plowing-harrowing) in both years (Table 2).…”

“…In this experiment, the no-till treatment (T4) presented Ca 2+ content equivalent to treatments with soil revolving at the superficial soil layer (0-0.2 m). A great increase of soil acidity (low pH) and Al 3+ levels are regularly observed at soil layers below 0.4 m due to no influence of lime effects at such depths (Okorkov and Okorkova, 2013). Conyers et al (2003) discussed the movement of lime in soil surface and subsurface in no-till systems and concluded that the physical movement of lime in soil is probably through channels formed by dead roots left intact due to the lack of soil revolving, results that were not observed in this study.…”

In sugarcane expansion areas where soil fertility restrictions regularly occur, soil preparing ameliorates soil physical and chemical properties to improve conditions for sugarcane crop development. Therefore, the aim of this study was to evaluate soil chemical attributes under different soil preparation methods for sugarcane cultivation at the first and second year of expansion area in the Cerrado biome. The experiment was conducted in an area previously used as pasture land for more than 10 years with Brachiaria decumbens without any soil correction. CTC-2 sugarcane variety was planted. The experiment was set up as a randomized block design with six treatments and four replications. The treatments were: desiccation-liming-plowing-harrowing; liming-plowing-harrowing; liming-harrowing-plowing-harrowing; desiccation-liming-direct planting; desiccation-liming-subsoiling, and harrowing-liming-plowing-harrowing. Soil attributes: organic matter, water pH, H++Al3+, Al3+, m, V, H2PO4-, K+, Ca2+, Mg2+, and S-SO4-2 were evaluated at 0-0.2, 0.2-0.4 and 0.4-0.6 m soil depth. The variables were submitted ANOVA, joint analysis and Tukey’s test (p < 0.05). The treatments including liming followed by harrowing, plowing and harrowing, and harrowing followed by liming, plowing and harrowing, resulted in the largest gains in soil fertility. In the first year of sugarcane cultivation, the no-tillage system proved to be sustainable and appropriate for sugarcane cultivation economically viable.

ABSTRACT:In the area of expansion, where if you have restriction on fertility, soil preparation has contributed considerably to the improvement of the physical, chemical and water conditions of soils and, consequently, to the proper development of culture of sugarcane. The aim of this study was to evaluate the effect of different management techniques on the availability of nutrients in soil in an area of expansion of sugarcane, formerly with Brachiaria decumbens, in the Cerrado region. The experiment was conducted using the CTC 2 variety at Jalles Machado mill in Goianésia, GO. The experiment was established in a randomized block design, with six treatments and four replications. Chemical attributes of soil were evaluated at depths of 0-20, 20-40 and 40-60 cm. Significant differences were found among depths for all analyzed attributes. Adopted management systems influenced chemical attributes and the availability of nutrients for plants. Invertion of soil through plowing and harrowing is extremely beneficial to carry out soil amendment in the first year of cultivation, improving the incorporation and effectiveness of the corrective. The adoption of no-tillage system did not prove to be the best option for the first year of sugarcane cultivation, hindering the incorporation of the corrective.
