The case study where this research is concentrated is located in the city of Ensenada, where the demand for greater capacity in general basic services such as drinking water supply has created a greater problem when the availability of this resource is very limited by the climatic conditions and the natural environment in arid zones as it is in the North of Baja California. In this research we propose the design and installation of a rainwater collection system, with economic materials and common use that any inhabitant can acquire for their implementation in their own home. In this sense, dissemination has been promoted about the advantages of using natural resources based on collective awareness, emphasizing the scientific dissemination of knowledge. For this last point the moderation of the use of rainwater is made to cover the domestic demand for water through a rain collection system installed in a house of average family.展开更多

This nutrient absorbent polymer dramatically conserves water and reduces fertilizer usage while significantly increasing plant and crop yield. There are numerous benefits that LSWA is engineered to produce, and moreover, with every new application new benefits are discovered. The versatility of this additive will undoubtedly lead to some new applications. LSWA crystals in the soil absorb hundreds of times their mass in water and then, upon demand, release the stored moisture regardless of the soil condition. Unlike previously used polymers, LSWA has great absorbability even under soil pressure, and maintains its absorbability in the presence of fertilizers and other water soluble additives. It is completely non-toxic, and has a lengthy effective period of seven to ten years. LSWA is extremely cost effective due to its low initial cost, the dramatic reduction in the number of watering cycles, the decrease of fertilizer usage and the increase in crop yield, as well as allowing utilization of previously unusable land. When LSWA crystals are added into the soil, irrigation schedule times can be reduced by more than 50%, and fertilizer usage reduced by up to 33%. In this paper, some basic researches on the basic properties of the soil additive are reported. Some applications are described by reference to a number of case studies. Finally, specific recommendations are given for the application rates and methods for a range of crops and soil conditions.展开更多
