Table 2 defines crop sequence and the times when gypsum application, chiseling, and physical soil analyses were performed
Figure  1  - Sequential water balance during the 2015/2016 cropping season. PE = Potential evapotranspiration
Figure  2  - Soil water infiltration in relation to simulated precipitation by Cornell infiltrometer in different soil management systems and time necessary to start the runoff (No-tillage without gypsum = 4’32”; No-tillage with gypsum = 5’56”; Chiseled so
Figure 3 - Penetration resistance (PR) evaluated up to 0.50 m at the beginning of the experiment (May/2014) (3A) and January/2016 (3B), under different soil management systems
