چکیده
Abstract Conditioning alkaline soil with acidic phosphorus-rich biochar might contribute to improving phosphorous (P) availability and waste utilization efficiency. In this study, was prepared using halophyte (HBC) modified by H 3 PO 4 (P-HBC) P 2 O 7 (PA-HBC). The P-containing groups fractions in the HBCs were characterized, effects of on examined incubation experiments. results showed that pH P-HBC (3.31) PA-HBC (2.17) significantly reduced compared HBC, total contents rose 4.66 g·kg − 1 5.24 , respectively. spectral characterization confirmed loading functional after modification. application soils decreased facilitated transformation stable into active fractions. Overall, can be employed increase activity soil. Graphical

This study examined the concentration of organic and inorganic phosphorus in surface soils of a Bouteloua gracilis-Bouteloua eriopoda grassland, and a Larrea tridentata shrubland, in the northern Chihuahuan Desert, New Mexico, USA. In this desert where the grassland vegetation has a uniform spatial distribution and individual shrubs have a patchy spatial distribution across the landscape, veget...
متن کاملPhosphorus speciation in manure-amended alkaline soils.
Two common manure storage practices are stockpiles and lagoons. The manure from stockpiles is applied to soils in solid form, while lagoon manure is applied as a liquid. Soil amendment with manure in any form introduces a significant amount of phosphorus (P) that exists in both organic and inorganic forms. However, little is known about P speciation in manure stored under different conditions, ...

to evaluate the relationships between soil inorganic phosphorus p (pi) fractions, the soil p test and plant parameters such as plant p uptake, dry matter yield, tissue p concentra-tion and relative yield, glasshouse experiments and chemical analyses were conducted on 13 calcareous soils from six agricultural and seven adjacent bushland (virgin soil) sites. four rates of p (0, 15, 30, 60 mg/kg s...
