“…At 90 DAA all treatments without the soil mobilization presented levels equivalent to the control, which did not receive N during the three years. This behavior was expected, because the increase in mineral N content resulting from the fertilizers is not permanent (Gonzatto et al, 2016), this is due to N absorption by the plants, and above all, to losses processes that usually occur with this nutrient, especially by nitrate leaching and denitrification (Bayer et al, 2015;Rauber et al, 2017).…”

“…When the N fertilizers are incorporated in the soil, the N losses by ammonia volatilization decrease sharply due to the exposure of ammonia in the air is reduced and its retention by soil particles increases (Dell et al, 2012;Aita et al, 2014;Rauber et al, 2017). In addition, incorporation increases the chances of the ammonia react with acidic soil zones, incorporating proton and returning the form of ammonium.…”

“…The EI DCD acts on the enzyme ammonia monooxygenase, delaying the nitrification (Gonzatto et al, 2016), while the NBPT inhibits the enzyme urease and acts by lengthening the urea hydrolysis period (Manunza et al, 1999). The duration of the effect of inhibition is also distinct, the DCD acts in the soil for up to 30 days, depending on the conditions of temperature and humidity (Kelliher et al, 2008;Rauber et al, 2017Rauber et al, , 2018, while the NBPT has effect not more than 15 days after its application (Dall'Orsoletta et al, 2017). Thus, the treatments with the addition of EI maintained higher soil mineral N content up to the 30 DAA and after this time, with the reduction of the effect of EI, this content tended to be similar among the treatments.…”

The incorporation of nitrogen (N) fertilizers in the soil and the use of enzyme inhibitors (EI) can improve the efficiency of N fertilization by reducing losses by ammonia volatilization and nitrate leaching. This study aimed to evaluate the efficiency of EI addition and fertilizer incorporation on both grain and dry mass yields of corn as well as on some soil chemical properties, with focus on N availability. A field experiment was carried out for three years in randomized blocks with four replications. The treatments consisted of a 2 × 5 factorial, including two forms of fertilizers application: superficial (SUP) and incorporated (INC), allocated in the plots; and five fertilizations: mineral fertilizer (NPK); NPK + EI; pig slurry (PS); PS+EI; and control (TEST), allocated in the subplots. The soil mineral N content was determined at 30, 60, and 90 days after fertilizer application (DAA) and these times were considered as sub-subplots. All fertilizers increased the dry corn matter and grain yields and the soil availability of N, P, and K, mainly in the upper layer (0.00-0.05 m). However, only the PS promoted higher productivity when incorporated into the soil relative to the soil superficial application. The incorporation of fertilizers increases soil available P but has little effect on soil mineral N. The EI addition to the fertilizers promotes higher soil mineral N contents in the soil until 30 and 60 DAA respectively when superficially applied and soil incorporated, although this does not increase the corn productivity.

“…Besides that, in the no-tillage system, in which liming is not incorporated, soil correction is restricted to the surface layers, potentially resulting in the "overliming" effect (Rheinheimer et al, 2018). Therefore, in addition to unnecessary expenses, chemical imbalance detrimental to plant development might occur, as low availability of cationic micronutrients (Saha et al, 2019), ammonia volatilization (Rauber et al, 2017), and formation of calcium phosphate precipitates (Penn & Camberato, 2019).…”

The elemental sulfur (S0) application may reduce soil pH, benefiting plants adapted to acid conditions and lessening problems of overliming. Nevertheless, there is no official recommendation for its application. The objective of the study was to quantify the S0 doses required to reduce the pH of soils from Southern Brazil. The experiment was carried out in the laboratory in a factorial scheme (5 × 5), with a completely randomized design and three replicates. The treatments consisted of five soils, and five doses of S0, corresponding to 0, 50, 100, 150, and 200% of the estimated dose need to reach pH 4.0. The applied doses of S0 resulted in reduction of pH and base saturation (V%) and increase of potential acidity (H + Al). These effects, however, were reduced due to the low rate of oxidation of the S0 applied (0.76-3.36%). The soil variables correlated with S0 oxidation were Mg2+ (0.86***), Al3+ (-0.82***), H + Al (-0.89***), V% (0.68***) and aluminum saturation (m%) (-0.87***). In the evaluated soils the oxidation of 50 kg ha-1 of S0 was required to reduce one unit of pH in H2O.

“…Unlike P, which is not lost by volatilization and, as a consequence, accumulates in the soil, much of the N from LSM applied to the soil is lost through volatilization within the first 24 hours after application (Rauber et al, 2017). In tropical soils, such as most of the Brazilian soils represented by Oxisols, P tends to remain in the superficial layers due to the soil mineralogical characteristics, which presents high concentrations of Fe and Al oxides, causing P to remain adsorbed in the system (Novais & Smyth, 1999).…”

This study aimed to evaluate the dynamics of phosphorus in the soil by the determination of phosphorus contents in an Oxisol cultivated with soybean during the 2016/2017 crop season, after 17 years of successive applications of liquid swine manure (LSM). The experiment was conducted in the experimental area of the University of Rio Verde. The treatments were: T1-control; T2-25 m3 ha-1 of LSM; T3-50 m3 ha-1 of LSM; T4-75 m3 ha-1 of LSM; T5-100 m3 ha-1 of LSM and T6-fertilization with mineral fertilizer. The subplots refer to soil depths: 0-10; 10-20 and 20-40 cm. The LSM was applied to the soil surface by spraying, before soybean sowing and the mineral fertilizer was applied to the furrow at the time of planting. After soybean harvesting, soil samples were collected at the studied depths for the determination of the contents of P in the soil. The contents of P in percolated water are within the concentration range considered adequate for human consumption. As for the contents of P in the soil, LSM applications on the soil surface increased the available soil P up to the depth of 20 cm. The highest dose of LSM applied to the soil promoted an increment of P contents that are within the safety range of the critical environmental limit of phosphorus (LCA-P), corresponding to 37% of this limit.
