Assessment of physicochemical properties of a loamy sand treated with biochar and dairy manure under silage corn production in western Newfoundland
Soil physicochemical properties play an important role in crop growth and final harvest. Different agronomic practices can improve soil health through modulating these physicochemical properties. Dairy manure (DM) is a good and abundant source of nutrients in Newfoundland, and both biochar (BC) and...

Soil physicochemical properties play an important role in crop growth and final harvest. Different agronomic practices can improve soil health through modulating these physicochemical properties. Dairy manure (DM) is a good and abundant source of nutrients in Newfoundland, and both biochar (BC) and DM are considered good soil amendments. A field experiment was conducted at Pynn’s Brook Research Station, Pasadena NL, to evaluate the effect BC and DM has on various soil physicochemical properties, as well as to establish a relationship between soil electrical conductivity (EC) and these selected physicochemical properties. Experimental treatments with four replicates included control, inorganic nitrogen (IN), IN+BC, DM, and DM+BC.
