The previous statement is confirmed by thecontent of humus, since its values get close to the vineyard optimum value in allthree treatments. Generally, our results are in accordance with the ones acquired byBiale (2000). He has taken into account several results and showed the averagevegetative yield and grape yield value obtained in Europe and Australia. Thecompost microorganisms decompose organic matter while their activity andenzymes, created during these processes, contribute to easier absorption ofnutritious elements by vine and other plants.C/N
