Side-band injection of acidified cattle slurry as starter P-fertilization for maize seedlings
Abstract Accumulation of phosphorus (P) in agricultural soils has caused increasing environmental concerns. Maize cropped for fodder implies return of animal manures rich in nutrients. In addition, starter fertilization with mineral P is used in cold conditions for maize cropping. It was hypothesized that the use of the additional mineral P could be excluded by increased availability of the P ...

Sulphur mineralization kinetics of cattle manure and green waste compost in soils
Sulphur mineralization of cattle manure (CM) and green waste compost (GWC) added to six agricultural soils with different chemical properties was monitored over 10 weeks in a laboratory incubation experiment. Although the amount of sulphur was higher in CM than in GWC, the cumulative SO4 2--S values in GWC-treated soils were higher than in soil amended with CM. The percentages of mineralized S ...

Phosphorus speciation and sorption-desorption characteristics in heavily manured soils
Managing heavily manured soils for decreased P loss to waters requires improved understanding of the chemical and sorption–desorption characteristics of P in these soils. We used soils from agricultural fields receiving 8 yr of dairy, poultry, swine manure or spent mushroom compost for the determination of P functional groups in NaOH-EDTA extracts by solution 31P nuclear magnetic resonance (NMR) ...

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 ...
