This paper describes the design, calibration and testing processes of a new device named Automated Laboratory Infiltrometer (ALI). It allows to determinate in laboratory, under controlled conditions the saturated hydraulic conductivity (Ks) of altered or unaltered soil samples which is a key parameter to understand the movement of water through a porous medium. The ALI combines the advantages of three different approaches: measures vertical infiltration rates in a soil column, measures the actual volumes of vertically drained water through the soil column, and finally, uses heat as a natural tracer to determinate water flux rates through the porous medium; all those parameters are used to determinate Ks. The ALI was developed using the popular Arduino microcontroller board and commercially available sensors that give the whole system a low cost. Data from the ALI are recorded in a microSD memory so they can be easily read from any spreadsheet software helping to reduce time consuming and avoiding reading errors. The performance of this device was evaluated by comparing the water flow rates determined by the three approaches for which is designed; an excellent correlation among them was observed (worst correlation: R2 = 0.9826 and r-RSME = 0.94%).

This research reports on two pepper species cultivated in a pilot plot and protected under white shade nets during the 2014, 2015 and 2016 growing seasons. The goal of the study was to compare crop yield, water productivity, and economic productivity between sorghum and corn as extensive crops (ECs), and habanero peppers and bell peppers as intensive crops (ICs). The average values of crop yield, water productivity, and economic productivity were 4.8 Mg (Tons) ha−1, 1.1 kg m−3, and 722.00 USD ha−1 for sorghum; and 7.0 Mg ha−1, 1.2 kg m−3, and 1390.00 USD ha−1 for corn. Average values of 45.0 Mg ha−1, 7.3 kg m−3, and 85,900.00 USD ha−1; and 72.5 Mg ha−1, 10.4 kg m−3, and 66,390.00 USD ha−1 were obtained for habanero peppers and bell peppers, respectively—both were cultivated during 2014, 2015 and 2016. According to the climate conditions of this region, crop water requirements for pepper crops are 41.66% higher than for grain crops; nevertheless, the on-farm water application efficiencies are 92% and 58% respectively. Consequently, 11.97% more water is used for ICs than for ECs. The economic profitability for farmers was 72 times higher for intensive crops than for extensive crops.
