The Effect of Bat Guano Applied to the Soil in Different Forms and Doses on Some Plant Nutrient Contents.

This research was conducted for the purpose of determining the effects of bat guano on plant nutrient contents in the soil and in lettuce (<italic>Lactuca sativa</italic> L.) during the spring of both 2014 and 2015 with three replications according to randomized blocks experiment design. Bat guano was applied to the soil in two different forms; According to the results organic matter, P, Cu and Mn amounts in the soil were found to be statistically significant and increased compared to the control. Likewise, in the application of bat guano dust, organic matter, P and Mn amounts in the soil were found to be statistically significant and increased compared to the control. In lettuce, N, K, Mg, Fe, Cu, Zn and Mn amounts in the application of bat guano powder and K, Ca, Mg, Fe, Zn and Mn amounts in the application of bat guano dust were found to be statistically significant.
