Abstract

This work tries to physically optimize Acacia cyanophylla compost. It is composed of crushed Acacia using various ways of mechanical screening and the incorporation of rabbit manures compost, according to different ratios. The various growth substrates obtained were subjected to physical analysis relating to water and air retention. Simple screening technique, using 6 and 8 mm meshes, are physically better than double and triple screening. The best ratio mixture between Acacia cyanophylla compost and rabbit manure compost was respectively 75% and 25%. For a better use of those substrates, further studies are needed to optimize their chemical and biological characteristics.
