MENDEZ-GARCIA, T.; PALACIOS-MAYORGA, S.  y  RODRIGUEZ-DOMINGUEZ, L.. Analysis of Soil, Leaf and Water Quality for Avocado. Terra Latinoam [online]. 2008, vol.26, n.1, pp.75-84. ISSN 2395-8030.

The nutritional state of avocado (Persea drymifolia L.), soil physical and chemical characteristics, and chemical quality of irrigation water were studied in family orchards in Nepantla, municipality of Tepetlixpa, State of Mexico. The soil of the area consists of an association of ocric and mollic Andisols (Ano ANm), which have traditionally been forest soils. In this region, however, they are now used for agriculture, since the local growers consider them suitable for avocado. Nevertheless, these soils are deficient in nitrogen (N), phosphorus (P), and to a lesser degree, manganese (Mn) and zinc (Zn). They also have low organic matter content (MO) and a high P fixation capacity. All these deficiencies can be corrected in most cases by good crop management practices. The irrigation water quality is good. This water, free of salinity, obtained from the mixture of rain and drinking water, is stored in reservoirs for both domestic use and orchard irrigation. An analysis of foliage of local trees detected deficiencies of N, P, potassium (K), iron (Fe), Zn, Mn, and boron (B), which can be corrected with appropriate fertilization.
