Leaf photosynthesis and rhizobial nitrogen fixation are the two metabolic processes of
utmost importance to legume growth and development. As these processes are closely …

Although most of the N required by soybean [Glycine max (L.) Merr.] is provided through the
process of symbiotic N2 fixation, supplemental N using broiler litter may boost soybean grain …

Nutrient over-enrichment from anthropogenic sources is a major stressor of aquatic,
estuarine, and marine ecosystems. Nutrients enter ecosystems through off-target migration …

Human activities have increased the amount of earth's reactive N, resulting in significant
improvements in crop yield and animal production but also in environmental degradation …

Most N2‐fixing prokaryotes are free‐living organisms or grow in association with various
plant or fungal species, but some have evolved to form symbioses with the relatively small …

Applying livestock manure to soil can enhance soil fertility and crop growth; however, little
information is available on the residual effects of manure on crop growth. The objective of …

This review is presented mainly to provide a research update, listing some of the
characteristics of the studies on gaseous N losses from soil. Nitrogen sources with greater …

Thoroughly tested simulation models are needed to help quantify the long-term effects of
agriculture. We evaluated the Root Zone Water Quality Model (RZWQM) response to …

Applying manure to soybean [Glycine max (L.) Merr.] as a routine management practice
requires additional information about cultivar‐dependent responses. Our objective was to …

Domestic animals in the USA produce over 1,032,000,000 Mg of manure each year,
resulting in 7,570,000 Mg of excreted nitrogen (N). If manure is to be used in a way to …
