ent management are important steps in increasing uptake of soil-available P and reducing P losses in runoff Haying common bermudagrass [Cynodon dactylon (L.) Pers.] is (Rowe and Fairbrother, 2003; Sharpley and Halvorson, commonly used to manage field-applied manure P in the southeastern 1994). Utilizing this manure resource by replacing comUSA but is limited to summer. This 3-yr study was done ...

A replicated randomized block trial was conducted to determine the response of Holstein cows rotationally grazing annual ryegrass-Crimson clover pasture to supplemental concentrate. Within each of 2 yr, 16 Holstein cows were assigned to one of four blocks by energy-corrected milk yield, days in milk, and parity. Treatments included one of four levels of concentrate based on the following grain ...

To better understand how residue quality and seasonal conditions influence the flow of C from both root and straw residues into the soil microbial community, we followed the incorporation of C-labeled crimson clover (Trifolium incarnatum) and ryegrass (Lolium multiflorum) root and straw residues into the phospholipid fatty acids (PLFA) of soil microbial biomass. After residue incorporation unde...

Legumes provide multiple ecosystem services in agricultural systems. The objectives of this study were to evaluate the influence different legumes through C rhizodeposition on dynamics C, N and P soil microbial communities’ resource requirements. pea (Pisum sativum L.), faba bean (Vicia white clover (Trifolium repens crimson incarnatum L.) non-legume wheat (Triticum aestivum grown pots. Carbon ...

Increasing atmospheric CO2 concentration has led to concerns about potential effects on production agriculture as well as agriculture’s role in sequestering C. In the fall of 1997, a study was initiated to compare the response of two crop management systems (conventional and conservation) to elevated CO2. The study used a split-plot design replicated three times with two management systems as m...

Techniques based on terminated cover crops are proposed in organic agriculture instead of traditional inter-row tillage for weed control subsequent grain crops. We estimated the profitability and evaluated riskiness novel techniques compared to one. Two-year yield data from three on-farm trials corn one soybean northern Italy were combined with cost revenue calculate compare gross margin distri...

Conservation management practices can improve soil health while minimizing deleterious effects of agriculture on the environment. However, adoption these practices, particularly cover crops, is not widespread, as they often reduce crop yields compared to traditional practices. The purpose current study was determine if a two-species treatment rye (Secale cereale L.) and crimson clover (Trifoliu...
