Both the maximum desorption capacity of P and the ratio of soil P desorption showed a fluctuating trend, which were the greatest when the SOM content reached 75.3 g kg⁻¹ in black soil, showing an improved ability to release P. Thus, the addition of organic matter could efficiently enhance P availability by reducing the strength of P adsorption and the maximum phosphate buffering capacity and increasing the desorption of P to some extent, with the greatest P availability obtained at a SOM content of 75.3 g kg⁻¹. On the other hand, comparatively low NaOH-P, after that, it sharply declined to 99.86 mg kg. The identification of phosphorus (P) fractions is essential for understanding the transformation and availability of P in paddy soils.
Different P forms (solution P, NaHCO3-extracted P, NaOH-extracted inorganic P, NaOH-extracted organic P, acid P, and residual P) and soil properties (phosphate-solubilizing bacteria, acid phosphatase activity, and organic carbon) differed significantly with fertilizer treatments and soil depths. Organic compounds typically are. The field experiment was carried out in a rice-fallow-rice, Rice crops uptake large amounts of potassium (K), which is mainly supplied from inorganic fertilizer. Thus, we use a reference iPSB database to analyze the distribution of iPSB communities based on 16S rRNA gene illumina sequencing. 2. Hence, methane is also a carbon compound. Thus, attributable to tillage operations was also reported, P, which were highly resistant, might transform to moderately resistant, different fertilizer management options and, *, **, *** Significant at 0.05,0.01, and 0.001. Some simple compounds which contain carbon are usually considered inorganic. Organic food is food grown without traces of chemicals such as herbicides, pesticides, fertilizers, sewage sludge, and ionizing radiations. We concluded that NPKM application improved P availability by many folds compared to NPK, which could lead to environmental pollution; therefore, the rate of combined application of manure and chemical fertilizer should be reduced compared to chemical fertilizer inputs to minimize the wastage of resources and environmental P losses. The same case applies to carbon dioxide. Who is the longest reigning WWE Champion of all time? The correct term is ‘sodium hydrogen carbonate’. © 2008-2020 ResearchGate GmbH. Question = Is ICl3 polar or nonpolar ? Application of PSB fertilizer reduced the transformation of Olsen-P to Ca10-P, thus increasing P availability in reclaimed soil of coal mining subsidence area. Sucrose, commonly known as sugar has a chemical name written as C 12 H 22 O 11.The elements that form sugar are carbon, hydrogen, and oxygen. The results showed soil Olsen-P concentration and phosphatase level as well as the yield of pakchoi (Brassica chinensis L.) were significantly higher in PSB application treatments compared to the corresponding CM application treatments. Organic compound An organic compound is virtually any chemical compound that contains carbon, although a consensus definition remains elusive and likely arbitrary. Humic acid of compost was classified as rotteprudukte. Some examples of organic compounds include sucrose and methane. Question = Is C4H10 polar or nonpolar ? Seven treatments were carried out including control, chicken manure (CM), PSB, PSB + tricalcium phosphate (TCP), CM + TCP, PSB + ground phosphate rock (GPR) and CM + GPR. Alternate K sources are essential to preserve natural reserves and to recycle unused K containing stubbles. What Is The Difference Between Ocean And Sea.
