Dynamic and quantity of N losses by volatilization and leaching in Brown Grayish soil of central Cuban region
An experiment was carried out during four harvests (two in the cold season and two in spring) with the objective ofdetermining the N losses by leaching and volatilization as well as their dynamics in a Brown Grayish soil in the Central Cuban region at the Experimental Station of Soil “Esca...
