Abstract :

This study was carried out to determine the use of pirina and pulp, as a soil fertilizer and conditioner. For this aim a greenhouse study was conducted in a randomized block design with 3 replications in 48 plots. Pirina and pulp residuals were applied to pots in 4 doses (pirina: 0%; 2,5%; 5%; 10% v/v-pulp: 0%; 2,5%; 5%; 10% v/v) with 2 bacterial applications (control and OSU-142). Application of pirina and pulp, to soil with low organic matter content, has affected physical and chemical properties positively. Depending on the applied doses and materials; aggregate stability, organic matter content, field capacity,electrical conductivity (EC), and available moisture content of soils were increased. However, changes in soil pH were not found statistically significant. When compared with control increase in electrical conductivity of soils were found as 148% and 108%with pirina and pulp applications, respectively. These values were found as 139% and 220% for organic matter contents. While aggregate stability (AS) of soils was found as 42% and 46% in controls, it was determined as 63% and 83% without bacteria,64% and 97% with bacteria applications, for pirina and pulp, respectively. As a result it can be concluded that application ofpirina and pulp to soils with low organic matter contents improves its physical and chemical properties.
