Manure and fertilizer applications contribute to greenhouse gas (GHG) and ammonia (NH ) emissions. Losses of NH and nitrous oxide (N O) are an economic loss of nitrogen (N) to farms, and methane (CH ), N O, and carbon dioxide (CO ) are important GHGs. Few studies have examined the effects of low-disturbance manure incorporation (LDMI) on both NH and GHG fluxes.

- Tillage methods for manure can reduce nutrient loss but may harm cover crops and increase soil erosion; low-disturbance manure application (LDMA) shows promise for improved practices.
- A study at the University of Wisconsin found that different manure application methods, including LDMA, effectively increased corn yields compared to no manure, with the best results stemming from sweep injection.
- LDMA not only helped maintain crop residue and reduced damage to winter rye but also matched fertilizer nitrogen treatments in yield while enhancing soil quality by improving nitrogen conservation and soil carbon content.
The impacts of low-disturbance manure application (LDMA) on runoff water quality in hay crop forages are not well known. Our objective in this study was to determine surface runoff losses of total nitrogen (TN), ammonium N (NH -N), nitrate N (NO -N), total phosphorus (TP), dissolved reactive P (DRP), and suspended sediment from alfalfa (Medicago sativa L.)-grass plots in central Wisconsin after surface broadcasting manure and LDMA compared with no application.

Study Design: Ten previously described and commonly used cytologic criteria were evaluated and graded on a 0-4 scale in a consecutive series of thyroid fine needle aspirations (FNAs) reported as follicular or Hürthle cell neoplasms or lesions. Scoring was compared to subsequent surgical outcome.
Objectives: In a large retrospective study, the association of smoking with human papillomavirus (HPV) genotype and vaginal intraepithelial neoplasia (VAIN) grade was analyzed.
Methods: A SNOMED search was performed for vaginal biopsy or resection specimens diagnosed as VAIN over an 11-year period. The diagnosis of VAIN grade was confirmed by histological review.
