(KIMOTO, 1993). BULLUCK et al.
(2002) they affirm that used organic composites as alternative meliorates of the fertility of the ground, can result in increment of the organic substance and biological activity of the ground. The organic fertilization is useful the recycling to it of agricultural residues, what it makes possible greater autonomy of the producers in face of the commerce of summons and presents great residual effect. Several are the possible organic substratum sources to be used in the production of Hortensia. The Biotech is a product consisting of acid organic plus an enzymatic complex, is presented in the physical states: as liquid Biotech, with the addition of the enzymatic complex in suspension and as solid Biotech, with you leave carriers cation activator of natural enzymes of the ground. It serves to responsibility nutrient, (macro and micron), as much in the cationic forms as Cassini. (BEISNER, 1997; GUNTER; VOLKER, 2001; AMARAL et al., 2004; RENELLA et al., 2004; STROBEL, 2001). The use of the adoration of the Biotech ground in the plantation of sativa Lacteal lettuce to var. trespass, has the possibility to increase the productivity with the increase of the dosage of the product, ally the necessity of if to increase the productivity of the lettuce more the deepened study how much to the dosages of the adoration of the Biotech ground it could be tool in the handling of the culture of the lettuce.
