Corn Production Survey 2009

Data file: C2_FERTILIZER_USAGE

This file contains data related to usage of yield-enhancing inputs or fertilizers found in Section C2 (Fertilizer and Pesticides) of Block C (Information on Corn Harvested). Specifically, the file contains data on inorganic, organic, and other yield enhancing inputs applied on the entire or portion of the harvested area.

Inorganic inputs are grouped into two: the first four solid fertilizer grades commonly used by farmers, namely, urea, ammonium phosphate, ammonium sulphate and complete (which are categorized as “inorganic fertilizers”) and "other inorganic inputs" which may be in solid or liquid form.

Organic inputs may also come in solid and liquid forms.

All items contained in this file are found on page 3 of the CPS 2009 questionnaire.
