“…Textural (TP) and structural (SP) porosities: SP includes macropores (structural pores) that result from tillage, traffic, weather and biological activity, while TP includes micropores (textural pores) that result from the arrangement of elementary soil particles (Nimmo, 2004). Structural pores are subjected to short-term variations such as compaction by wheeling, whereas compaction does not affect textural porosity (Pereira et al, 2019). Using soil density values, TP and SP were estimated using Eqs.…”

A number of agroecological practices have been proposed for assessing soil quality. Several physical soil properties have been shown to be important for determining soil quality by using the sustainability index (SI) and the cumulative rating approach. The main aim of the study was to determine the effects of different agroecological managements on the physical properties of a Mollisol in the Mediterranean central Chile. In addition, some physical properties were selected to compare the soil quality among different agroecological management practices and highly mechanized intensive systems by using the SI and cumulative rating approaches. An experimental field was defined in an area of 3.5 ha in 2014. Four sites with different agroecological practices were selected in 2019 to assess soil physical properties: rainfed Mediterranean annual prairie - no tillage (1-S), irrigated perennial prairie with deep-root species - no tillage (2-N), irrigated annual and perennial prairie - conventional tillage (4-S), irrigated vegetables and flowers - minimum tillage (4-N); an avocado orchard with traditional management was used as the control. Soil organic carbon and the following soil physical properties were selected to assess SI and CR: bulk density, total porosity, void ratio, air capacity, fast-drainage pores, relative field capacity, hydraulic conductivity, structural stability index and unavailable water pores. The applicability of the selected physical indicators to the SIs of agroecological management practices compared with the control was demonstrated. The cumulative rating index (CR) for each land use showed that all agroecological practices constituted sustainable soil management (25≤CR<30), whereas the avocado orchard showed the least sustainable management (30≤CR<40), and a change in soil use is recommended.

The brick is composed of water, soil and cement, having an easy manufacturing process, with short construction and low cost is not subjected to burning is manufactured by a very different process from ceramic blocks, the same goes through a hydraulic press. This type of brick has characteristics that provide quality, sustainability, beauty, and above all savings in the total cost of the work. When used in construction are eliminated some steps and the execution time in the work. A block wall or ceramic brick will need roughcast, sketch, plaster, seamer and painting, besides considering the cost of these materials can not forget the labor that corresponds to an average 50% of the value of the work. But the great advantage over the other bricks is its construction system, once raised the wall this is ready, does not need finishing, and the pillar structure and beams are ready with it. Electrical and Hydraulic Installations are easily installed without the need for breakage and waste. These bricks do not require the use of mortars for laying, coatings such as plastering for regularization and finishing of walls, in addition to accelerating the work with their fittings that facilitate the alignment and plumb of the walls. The objective of this work is present through a literature review of optimization processes that involve the ecological brick. in addition to accelerating the work with their fittings that facilitate the alignment and plumb of the walls.
