May 1, 2022 · Abstract and Figures. Phosphorus (P) sorption by red soil is strong due to its acidic pH and high content of metal oxides. Biochar addition may increase the availability of red soil P by altering ...
Feb 28, 2022 · Rice is an important food crop in China, fertilization measures significantly affect soil properties and ultimately change rice yield. Thus, examining the effects of long-term green manure cultivation on the rice yield and the driving factors on rice yield, plays a crucial role in maintaining food security. Based on the long-term green manure cultivation, the treatments included no fertilizer ...
Aug 24, 2017 · 1. In ancient times, soils used to be classified into two main groups: Urvara (i.e. fertile), and. Usara (i.e. sterile) 2. In the 16th century A.D., soils were classified on the basis of their inherent characteristics and external features such as texture, colour, the slope of land and moisture content in the soil.
Jan 19, 2022 · The corrosion characteristics of carbon steel, galvanized steel, aluminum–zinc steel and copper were studied in the laboratory and in acid red soil. Red soil is a soil widely distributed in southern China, where the summer temperature exceeds 30 °C and the humidity exceeds 50, which is a typical acid soil environment.
Aug 25, 2022 · As one of the most serious soil erosion areas in China, red sandstone erosion areas in southern China have been seriously affected by abundant annual rainfall. To understand the effects of AM fungi and different grass strips on soil erosion characteristics in red sandstone erosion areas in southern China, we selected Cynodon dactylon, Lotus corniculatus, Zoysia japonica, and Astragalus sinicus ...
May 18, 2017 · Soil aggregation is one of the key properties affecting the productivity of soils and the environmental side effects of agricultural soils. In this study, we aimed to identify whether biochar could be used to improve aggregate stability. A 2-year field experiment was conducted to investigate the effect of biochar application (0, 2.5, 5, 10, 20, 30 and 40 t ha−1) on aggregate characteristics ...
May 8, 2022 · Phosphorus (P) sorption by red soil is strong due to its acidic pH and high content of metal oxides. Biochar addition may increase the availability of red soil P by altering P sorption characteristics. This study examined the influences of doping ratios of the biochar, phosphate concentration, solution pH, and biochar-derived dissolved black ...
