Experimental Study on Methods for Injection and Mixing of Nitrogen for Surface Irrigation Fertigation
1993
Lammouchi, S.
The present work on fertigation under a surface irrigation method represents the beginning of a long term research being conducted at the IAM of Bari. Chemicals and fertilisers injected, directly into the irrigation water and applied through surface systems, are subject to the low uniformity of water application. The recent achievements in surface irrigation have enabled achieving a high irrigation efficiency as pressurised systems. A kind of farm irrigation canal has been constructed for the purpose, in order to evaluate the applicability of furrow irrigation, as an example of surface method, for fertigation. Results showed a high efficiency in the distribution of fertiliser in addition to its independence of the hydraulic characteristics of flow. Moreover, in the application of fertigation, special emphasis is to be given to the modes of fertilisers mixing, taking into account the chemical and physical characteristics of the fertilizers and of irrigation water.
