Streszczenie:

The Midwest US has experienced significant changes in agricultural land use and management practices in recent decades. Cropland expansion, crop rotation change, and crop phenology changes could lead to divergent environmental impacts on linked ecosystems. The overall objective is to examine agricultural land use and management changes and their impacts on water quality in the Midwest US, which is addressed in three separate studies. The first study examined spatial and temporal dimensions of agricultural land use dynamics in east-central Iowa, 2001-2012. Results of this study indicated that i

The plant-soil nitrogen cycle plays a significant role in allocation of available N to plants, and improved understanding of N cycling helps sustainably increase fertilizer use efficiency. There are various processes (nitrogen mineralization and nitrification) involved in the availability and mobility of nitrogen in the soil. The primary objective of this study was to determine the NUE under contrasting nitrogen treatments over a period of five years.

Organically certified farms using compost to improve or maintain fertility rarely consider compost carryover and its impact on the determination of economically optimal application rates. Compost carryover is comprised of nutrient and non-nutrient elements. Both affect crop growth, yet carryover is typically described primarily in terms of nitrogen (N)-carryover only. This study tested a new method for estimating compost carryover on organically certified land and expressed carryover in units that capture both the nutrient and non-nutrient components.

Scenarios describe system functionalities and, when supplemented with performance annotations, provide a basis for performance analysis. This thesis presents a Core Scenario Model (CSM), which includes common scenario information in the Use Case Maps (UCM) notation and in UML 2.0 activity diagrams and interaction diagrams. The intent is to enable automatic transformations from a given scenario model to CSM, and then from a CSM model to performance models, hence enabling performance analysis early in the development process. CSM captures scenarios, performance, and deployment information, and i

Two lactation trials were used to investigate corn grazing as a management tool for dairies. Control (n = 18) cows, housed in free-stall barns were allowed ad libitum access to TMR while Grazing (n = 18 to 36) cows were limit-fed TMR down to 70% of that in Controls and allowed 24-h access to corn plots. By wk 3, Grazing cows consumed 7.9 +/- 1.5 kg/hd/d of standing corn. By wk 7, the crop had matured and Grazing cows consumed 11.42 kg/hd/d of corn grain. Intake of TMR by Controls was 20.07 +/- 0.46 kg DM/hd/d, 19.78% greater than Grazing groups. Corn grazing had no impact on body weight, condi

The major digestive enzymes of larval Diabrotica undecimpunctata howardi, the southern corn rcotworm (SCR), have been investigated. A number of proteases have been identified, the majority cysteine proteases, some aspartic acid proteases are also present. In vitro assays of cysteine proteases showed that almost all activity could be arrested by E64 or chicken egg-white cystatin. This activity was also affected by TLCK, CpTI and thaumatin. Two inhibitory activities were demonstrated in protein extracts from rice seed. The first, oryzacystatin-I, caused marked inhibition of both the insect cyste

People with severe motor-impairments due to Spinal Cord Injury (SCI) or Spinal Cord Dysfunction (SCD), often experience difficulty with accurate and efficient control of pointing devices (Keates et al., 02). Usually this leads to their limited integration to society as well as limited unassisted control over the environment. The questions “How can someone with severe motor-impairments perform mouse pointer control as accurately and efficiently as an able-bodied person?” and “How can these interactions be advanced through use of Computational Intelligence (CI)?” are the driving forces behind th

The thesis work was made in cooperation with the I-EDDA project who evaluates the drill equipment used in core drilling. The aim of this work was to determine how and why the drill bits are worn. The work consisted of two parts; investigate drill bits used in field tests and develop a lab scale method to be able to change one drill parameter at a time and see how it affects the wear. During the field tests the rotational speed and the pressure on the drill bits were changed between the three boreholes drilled. In the lab test one parameter at a time was changed; the rotational speed, the water

The study analyzes this conflict as a system of interconnected and often conflicting interests, assumptions and ideologies about how knowledge is created and transformed from the research stage to the policy implementation stage. The goal of this study is to: 1.) analyze critical surface level and underlying factors that contribute to the conflict; 2.) analyze systemic processes between na

<p> The effect of feeding corn by-products on cow reproductive performance, as well as offspring growth and reproductive performance has been investigated through four separate studies. The first study was conducted to evaluate the use of dried distiller’s grains with solubles (DDGS) in beef cow diets during early lactation on both dam and heifer offspring growth and reproductive performance. Three diets, consisting of 0, 2.5 or 4.7 kg/d DM of DDGS were formulated to be isocaloric but the DDGS diets exceeded protein requirements. Milk production was not different, however, milk component

The current seven billion people on earth are expected to reach nine billion by 2050 with resulting demands on world food production. In addition, the quality of our environment is being impacted by human activities, including agricultural production and crop fertilization. Nitrogen (N) management is the process of applying N fertilizers in a way to maximize use of N by crops, while minimizing loss to the environment. It is becoming imp
