Were identified as areas of cultivation and took a sample batch. Subsequently prepared the 18 samples collected in the Soil Laboratory of the National University Hermilio Valdizán and analyzed the following parameters: texture (Bouyoucos method), pH (potentiometric method), limestone (volumetric method), organic matter (method of Walkley and Black amended), total nitrogen (using a conversion from organic matter), phosphorus (method of Watanabe and Olsen amended) and potash (method of Morgan). The work was based on a methodology ¬ exploratory, descriptive, not to include references to quantified on the physicochemical characteristics of soils of orchard fruit Olerícola-Cayhuayna, which came to identify the predominant soil texture in the Garden Sandy is Cayhuayna of Franco with a low content of clay that shows a trend of erosion to be controlled by changing the irrigation system and the incorporation of organic matter. We conclude that the reaction is found in soil ranges that vary from neutral to moderately alkaline, but the content of calcium carbonate that is found at levels ranging from medium to low, we suspect that a problem of salinization may be due to improper use of fertilizer, irrigation with water of poor quality or inadequate irrigation practices.
