| Suction cups are the only viable method to obtain in situ the soil solution along the culture in real time (24 h). The soil solution is the objective criterion to modify the nutrient solution, so that it can be an appropriate tool for fertirrigation management. The nutrient levels of the soil solution must be known to establish the appropriate approach to nutrients management. In this work, levels of pH, EC,NO3-,NH4+, H+2PO4- , K+, Ca2+, Mg2+, Na+ and Cl- of the soil solution of three tomato crops were followed for periods 1995/96 and 1996/97 culture estimated in a trial carried out during two years. |

| In this study there was evaluated the economic profitability of tomato production under greenhouse conditions four production projects, in an area of 9 040 m2., in the communities of San Martin, San Pedro and Los Reyes Acaxochitlán's municipality, Hidalgo State, during the 2008-2009 cycle. How indicator was used cost/benefit ratio (C/B). Acaxochitlán's municipality produces 1,582.3 tons of tomato in a surface of 65 200 m2. In the four projects reviewed obtained a production of 218 tons, the average selling cosprice was $ 8.25 per kilogram, and sold in the cities of Tulancingo, Acaxochitlán and Pachuca. Tomato production proved a profitable activity in the study region since the projects 1, 2, 3 and 4 showed a ratio C/B of 2.30, 2.65, 3.09 and 1.57,... |
