Estimation of Watershed Nitrate Loads on Drained Agricultural Lands
Jiang, Yan, M.S.A.B.E., Purdue University, December 2013. Estimation of Watershed Nitrate Loads on Drained Agricultural Lands. Major Professor: Jane R. Frankenberger. Estimation of nutrient load is critical for many applications in water quality management; however, infrequent data monitoring and measurement error could raise considerable uncertainty in the load estimations. The objectives of t...
متن کاملWatershed Models for Predicting Nitrogen Loads from Artificially Drained Lands
Non-point sources of pollutants originate at the field scale but water quality problems usually occur at the watershed or basin scale. This paper describes a series of models developed for poorly drained watersheds. The models use DRAINMOD to predict hydrology at the field scale and a range of methods to predict channel hydraulics and nitrogen transport. In-stream changes of N load are estimate...
متن کاملsowing depth effects on vetch yield in maragheh dry lands
increases forage production and economic production in rainfed condition requires attention to agricultural issues such as determination of appropriate sowing depth. so in order to determine the effect of different sowing depths of vetch this experiment was conducted in agricultural research station of maragheh as strip plot based on randomized complete block design with three species of vetch ...
متن کاملCarbon consequences and agricultural implications of growing biofuel crops on marginal agricultural lands in China.
Using marginal agricultural lands to grow energy crops for biofuel feedstocks is a promising option to meet the biofuel needs in populous China without causing further food shortages or environmental problems. Here we quantify the effects of growing switchgrass and Miscanthus on Chinese marginal agricultural lands on biomass production and carbon emissions with a global-scale biogeochemical mod...
متن کاملPrediction of chronological age based on Demirjian dental age using robust ridge regression method
Introduction: Estimation of age has an important role in legal medicine, endocrine diseases and clinical dentistry. Correspondingly, evaluation of dental development stages is more valuable than tooth erosion. In this research, the modeling of calendar age has been done using new and rich statistical methods. Considerably, it can be considering as a practicable method in medical science that is...
