Among the radioactive products is phosphorus-32, which is formed, for example, in relatively large yield in bombardments of aluminium-27 with Nions. We have carried out experiments designed to show in what chemical state these atoms are held in the target....
Effects of Nitrogen, Phosphorus and Potassium Fertilisers on the Dry Matter Yield and Chemical Composition of Amaranthus Hybridus Subspecies Hybridus (Green Head)ABSTRACTdoi:10.1080/00128325.1993.11663188Adipala E.Mugerwa J.S.Taylor & FrancisEast African Agricultural Journal...
Summary It was found that nitrogen sources and phosphorus concentration play an important role in the fermentative production of acetone and butanol by Clostridium acetobutylicum. Addition of different concentrations of corn steep liquor, fodder yeast, soybean meal, corn bran, rice bran, and KH2PO4 ...

Soil organic carbon (SOC), total nitrogen (TN), and their ratio (C:N) play important roles in preserving soil fertility, and their values are closely related to fertilizer use. However, the overall trend and magnitude of changes in SOC, TN and C:N in response to chemical nitrogen fertiliz...
Organic carbon (C), nitrogen (N) and phosphorus (P) nutrients and their stoichiometry were measured in shoot and soil. P and NP fertilization increased shoot C concentration (3.12%, 0.91%), and all fertilization decreased shoot N concentration (6.96%). The variation of shoot C and N ...
Here we applied the latest statistical data (2000–2018) and simple quasi-mass-balance methods of net anthropogenic nitrogen and phosphorus inputs (NANI and NAPI) to estimate spatio-temporal heterogeneity of N and P inputs. The results show that while NANI and NAPI are first decreasing, this ...
