*Coffee - Production and Research*

Soil organic matter and soil pH (**Figure 3**), whose mechanisms involved depend on the substitution of aluminum by calcium in the sortive complex, participate in the soil aggregation whose formation and stabilization of the different classes of soil aggregate sizes will allow more or less lower aggregation, resulting in greater or

*Mean weight diameter (MWD) of the aggregates of a Red Latosol cultivate coffee 6 months after liming.* 

In a field experiment conducted in a Rhodic Hapludox cultivated with coffee, 2 years after the surface liming, Roth et al. [21] highlighted that the aggregation of solid particles exerts a significant action on soil susceptibility to accelerated water erosion for uncovered soil conditions. This study showed that after 60 min of simulated rainfall at an intensity of 60 mm per hour, soil maintained without soil correction with pH = 5.2 provided total infiltration of 56% of the total precipitation [21]. On the other hand, the authors observed that the best liming treatment to increase pH 7.0 provided 83% of total infiltration. In soil with pH 6.0 and with the application of plaster, the total infiltration was 67% of the total

Traffic of machines, soil tillage, and weed control methods are the main causes

of change in soil physical properties in coffee crop. However, management of soil acidity with limestone and use of gypsum also can change soil physical and electrochemical properties, which are related with dynamic processes like soil air and hydraulic permeability into soil which are essential to root development and
