Use of apparent soil electrical conductivity to improve sugarcane nutrient management in Florida* [Full subscriber]

Abstract      Precision agriculture is considered to be one of the most promising approaches for sustainable farming, but it requires efficient methods for accurately measuring within-field variations in soil physical and chemical properties. Apparent soil electrical conductivity (ECa) is a quick indirect measurement of soil EC with a sensor (e.g. EM-38), and the latter is used to determine spatial variations of this parameter in the field without extensive soil sampling. Correlation of ECa values with different soil nutrients in organic and mineral soils in southern Florida can help in determining its potential use to improve nutrient management in sugarcane.
