Field Methods To Enhance Degradation Of Nitrate In Surficial Soils, Urko Atxotegi Alegria

Dissertations and Theses @ UNI

An environmental field study was conducted from April to October 1998 in the Black Hawk County, Iowa. The main goal of the study was to find an appropriate field method to enhance degradation of nitrates in the surficial soil. Seven different methods were developed in the study to compare between four variables. The variables that were investigated were the source of nitrates, the moisture content of the soil, the uptake by plants and the total carbon content of the soil. The investigation has also been conducted to find out the specific influence of each parameter on landuse. A weather station …
