Abstract

Agricultural leaching is where nutrients, minerals, and chemicals from the soil contaminate the groundwater after rainfall and irrigation. A method used to prevent leaching is the use of nitrate inhibitors but recently a minerals have been used. The purpose of this experiment was to find a more abundant and efficient method of reducing nitrate leaching in soil. The effectivness of clinotpitolite minerals vs dicyiandiamide were observed in this experiment. It was hypothesized that 5 grams clinotpitolites will reduce the amount of nitrate leaching from silt loam soil greater than the 5 grams of dicyandiamide.A one-way ANOVA showed that the differences between the control ( n = 30, M = 9.000, SD= 2.034), the clinotpitolite soil mixtures ( n = 30, M = 4.172, SD= 2.575), and the dicyandiamide soil mixtures (n = 30, M = 7.633, SD = 2.846) were statistically significant, F(5,174) = 50.07, p < 0.001 < α = 0.05. A post hoc Tukey test was performed with the data at an at α = 0.05 on the nitrate concentrations of different soil mixtures to decide where the mean differences are between the groups. The results showed there was no significant difference between the before and after of the control, but there was a significant difference between the after for the control and the after of the clinotpitolie and dicyiandiamide soil mixtures. There was also a significant difference between the before after of the clinotpitolite soil mixtures, the before and after data of the dicyandiamide soil mixtures, and the after data of the clinotpitolie and dicyiandiamide soil mixtures. These results show that the clinopitolite decreased the nitrate leached from silt loam soil more effectively than the dicyandiamide. In conclusion, the hypothesis was supported and clinotpilite could potentially be used to reduce the amount of nitrate leached from soil.
