Field-Specific Nitrogen Management for Sugarcane Using Electrical Conductivity In-Situ Measurements
Int. J. Agron. Agri. R. International Journal of Agronomy and Agricultural Research (IJAAR) ISSN: 2223-7054 (Print) 2225-3610 (Online) http://www.innspub.net Vol. 16, No. 4, p. 43-53, 2020 RESEARCH PAPER OPEN ACCESS Field-specific nitrogen management for sugarcane using electrical conductivity in-situ measurements Andrea M Flores*1, Pearl B Sanchez2, Pompe C Sta Cruz3, Rodrigo B Badayos2, Patrick M Rocamora2 1College of Agriculture, Cagayan State University, Piat Campus, Piat, Cagayan, Philippines 2Agricultural Systems Institute, College of Agriculture and Food Science, University of the Philippines Los Baños, Laguna, Philippines 3Institute of Crop Science, College of Agriculture and Food Science, University of the Philippines Los Baños, Laguna, Philippines Article published on April 30, 2020 Key words: Nitrogen (N) management, Soil electrical conductivity (EC), Sugarcane Abstract The study was conducted to determine the potential use of soil electrical conductivity (EC) in developing field- specific nitrogen fertilizer recommendation for sugarcane. Relationship of field EC (in-situ measurement) with other soil physico-chemical properties such as texture, cation exchange capacity (CEC), pH, total N, available P and exchangeable bases including K, Ca and Mg were established. Soil samples representing the following series; Guimbalaon (Typic Hapludands), Silay (Aquic Hapludalfs), Manapla (Typic Hapludults), Pulupandan (Typic Ustipsamments), San Manuel (Typic Eutrudepts), La Castellana (Typic Humitrudepts) and Bago (Vertic Argiudolls) in La Carlota Sugar Mill District, Negros Occidental, Philippines were studied. Significant positive relationships were observed between field EC and soil pH (r=0.51*), laboratory EC (r=0.59*), CEC (r=0.74**), clay content (r=0.74**) and exchangeable Ca (r=0.79**) and Mg (r=0.86**), while negative correlation was noted between field EC and sand content (r=-0.57*). -

The role of clay minerals In the physico-chemical properties of soils, such as pH, cation and anion exchange capacities, buffering capacity, nutrient fixation, plasticity, swelling and shrinking, permeability, particle density, and tilth, has been established thoroughly by various workers (Grim, 1953; Kelly, 19^8; and Bear, 1964). A knowledge of the clay mineralogy of a given soil is therefore warranted If an effective assessment of its use capabilities is to be made.
