Resources about the status of micronutrients especially zinc in the Philippine soils
are very limited due to fact that most of the soil fertility surveys or studies conducted in
our country gives more emphasis on the major nutrients which is macronutrients such as
the nitrogen (N), phosphorus (P), potassium (K), sulfur (S), magnesium (Mg) and calcium
(Ca) since they are taken up by our crops in large quantities (Palanog, 2019). Thus, it is
being recognized that zinc deficiency is becoming a global and national problem in
farming the agricultural soils. The situation above creates the need to inventory the
status of micronutrients of major soils in the country which could be used as technical
basis to conserve and prevent deficiencies before it becomes aggravate and difficult to
manage (Agustin, L.C. et al., 1988). The researcher conducts soil survey of the major
soil series in La Union to assess the current status or condition of the zinc level and its
sufficiency. The result of this study about the available zinc content of the sampling sites
is from borderline to very low which means that most of the soils in the major soil series
of the study site are deficient. The correlation of zinc to the soil pH, electrical
conductivity, clay content and organic matter are only observed in the following: the pH
of Burgos series with a strong positive correlation, pH of Bauang with strong negative
correlation, and strong positive correlation of organic matter content with zinc level in
the soil series of Bauang, Sinapangan and Burgos.
