A comparison of soil management systems for urban agriculture
Soil contamination is a universal concern of urban agriculture. Reliable soil management systems are desirable in order to provide ideal growing conditions for urban crops. Due to concerns such as soil contamination, alternative soil management systems (e.g. raised-beds) are necessary to provide …

Fostering Populations of Arbuscular Mycorrhizal Fungi Through Cover Crop Choices and Soil Management
… these fungal populations to increase crop and soil benefits, including yield. Cover cropping, the growing of non-food crops outside of regular crop produc-tion for the role of protecting and improving soil, has also been suggest-ed to influence both the diversity and abundance of AM fungi. A …

Exploring Diversified Vineyard Ecological Soil Management Strategies: Impacts of cover cropping, Spanish River Carbonatite, and smooth pigweed (Amaranthus hybridus) interactions on an agroecosystem
… essential services for human well being. Intense management of agroecosystems has led to global degradation of soil and reduced biodiversity, two of the major challenges faced by agriculture today. Soil, the foundation of an agroecosystem, forms the base for cropping systems and how it is managed …

The effect of different fertilizer treatments on the nitrogen and organic matter content of a soil when cropped to a definite rotation for a period of twenty-four years
In a large part of the soil fertility studies that have been attempted in the past, a great number of the results obtained were based almost entirely on crop yields. These yields were used as the final criterion upon which to draw conclusions as to whether a given system of soil management was a …

Managing Cattail (Typha latifolia) Growth in Wetland Systems
… availability, water depth, competition, and soil management effects on cattail (Typha latifolia) growth in wetland systems were examined. Soluble reactive phosphorous (SRP), nitrate-nitrogen (NO3-N), and ammonia-nitrogen (NH3-N) removals were tested at a constructed wetland receiving …

Soil health assessment of the Sanborn Field long-term experimental study
Soil health assessment uses a combination of potential indicators affecting soil processes to comprehensively monitor soil change, caused by cropping systems and soil management. The objectives of the study were to assess the effects of selected cropping systems, soil management and landscape slope …

RESOURCE USE RATES: ESTIMATION OF TIME INVARIANT DECISION RULES (EROSION)
<p>As interest in soil conservation has increased, understanding the soil management decision rule used by farmers has become more important. The model developed to analyze the optimal decision rule for soil use rates is essentially a supply response model which assumes rational expectations. It …

Settlement and landscape in the Northern Isles; a multidisciplinary approach. Archaeological research into long term settlements and thier associated arable fields from the Neolithic to the Norse periods.
… Central to this research has been the study of soil management strategies of arable plots surrounding settlements from the Neolithic to the Iron Age. It is argued that this arable system provides higher yields in marginal locations. The ability to enhance yield in good years and to store surplus …
