Phosphorus Accumulation and Sorption in Calcareous Soil under Long-Term Fertilization
Application of phosphorus (P) fertilizers to P-deficient soils can also result in P accumulation. In this study, soil P status and P uptake by apple trees were investigated in 5-, 10-, and 15-year-old orchards in the semi-arid Loess Plateau, China, and subset soils with different soil P statuses (14-90 Olsen-P mg kg(-1)) were selected to evaluate the characteristic P adsorption. Due to the low ...
متن کاملReactivity and effectiveness of traditional and novel ligands for multi-micronutrient fertilization in a calcareous soil
This study compares the effectiveness of multi-micronutrient formulations containing iron (Fe), manganese (Mn), and zinc (Zn) with traditional (EDTA, DTPA, HEEDTA, and EDDHAm) or novel chelates (o,p-EDDHA, S,S-EDDS, and IDHA) and natural complexing agents (gluconate and lignosulfonate). The stability and reactivity of the formulations were studied on batch experiments with calcareous soil and b...
متن کاملEffects of long-term fertilization on soil humic acid composition and structure in Black Soil
The composition and structure of humic acid (HA) can be affected by fertilization, but the short-term effects are difficult to detect using traditional analysis methods. Using a 35-year long-term experiment in Black Soil, the molecular structure of HA was analyzed with Fourier transform infrared spectroscopy (FTIR), 13C nuclear magnetic resonance spectroscopy (NMR), and fluorescence spectroscop...
متن کاملA Culture Medium from Groundnut Meal
Acton el al. (1932) used a vegetable medium from a green variety of mung dal (Phaseolus mungo) for cultivation of the intestinal bacteria. Brewer (1943) suggested a mixture of soyabean and cotton seed or peanut meal for the preparation of a general purpose media using sodium sulphide as an activator; the sodium sulphide would readily generate sulphuretted hydrogen which by lowering the pH of th...
متن کاملHardwood biochar and manure co-application to a calcareous soil.
Biochar may affect the mineralization rate of labile organic C sources such as manures via microbial community shifts, and subsequently affect nutrient release. In order to ascertain the positive or negative priming effect of biochar on manure, dairy manure (2% by wt.) and a hardwood-based, fast pyrolysis biochar were applied (0%, 1%, 2%, and 10% by wt.) to a calcareous soil. Destructive sampli...
