Decomposition of carbon-14-labeled organic amendments and humic acids in a long-term field experiment
The stabilization of soil organic matter (SOM) is an important process in the context of global change and is strongly affected by soil use and management. We investigated the mineralization and stabilization of 14C-labeled wheat (Triticum aestivum L.) straw and 14C-labeled farmyard manure under different cropping systems (crop rotation, monoculture, and bare fallow) in a long-term field ...

Consequences of conventional versus organic farming on soil carbon: results from a 27-Year field experiment
Organic farming practices are regarded as being beneficial for the environment by promoting soil quality and sequestering soil organic carbon (SOC). We studied SOC dynamics in the long-term field experiment DOK in Switzerland. The experiment compares three organically fertilized treatments under conventional (CONFYM), bioorganic (BIOORG), and biodynamic (BIODYN) management, and two systems with ...

Zonejection: Conservation tillage manure nutrient delivery system
Manure application in minimum till (MT) systems is a challenge worthy of attention because residue cover is a keystone for environmental protection. To develop a system combining zone tillage and manure application into one operation (zonejection), two experiments were conducted. In Exp. 1, liquid swine manure (LSM) was applied in fall or spring for two site years (A, B). In Exp. 2, LSM was ...

Methane and carbon dioxide emission from two pig finishing barns
Received for publication July 22, 2007. Agricultural activities are an important source of greenhouse gases. However, comprehensive, long-term, and high-quality measurement data of these gases are lacking. This article presents a field study of CH4 and CO2 emission from two 1100-head mechanically ventilated pig (Sus scrofa) finishing barns (B1 and B2) with shallow manure flushing systems and ...

Crop productivity and economics during the transition to alternative cropping systems
Many environmental benefits accrue from reducing tillage and increasing crop diversity; however, economic factors often encourage the continued use of intensive tillage and specialized crop production. This study examined crop yields, input costs, and economic returns during the transition to a range of cropping system alternatives in the northern Corn Belt region, including different system ...

Lagoon treatment for manure case study
Are you getting a scale build up in your recirculation system from your manure holding ponds (lagoons)? Is it calcium carbonate or struvite (magnesium-ammonia-phosphate) crystals? In some CAFO sites, they will use anaerobic lagoons to reduce the amount of manure that they need to treat. In a zero oxygen environment the anaerobic bacteria will take the manure which is loaded with nutrients and ...

CAFO Manure Treatment-Struvite Removal and Struvite Prevention
CAFOs (Confined Animal Feeding Operations) face struvite in their manure holding ponds and manure lagoons, as well as their recirculation systems. On a dairy farm in Neb. that operated with 15,000 milking cows, they were generating 500,000 gal per day of wastewater laden with manure. Over the summer, they noticed a reduction in their pumping capacity because the first lagoon was filling faster ...

Enhancing Dairy Farm Efficiency with Manure Separators
Dairy farming is not only a crucial part of our food industry but also a significant contributor to agriculture's environmental challenges. Managing dairy waste, especially manure, is a pressing issue that has wide-reaching implications for both the farming community and the environment. In this blog post, we will delve into the importance of manure management in dairy farms and explore the ...
