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...

Determination of a pyrite contaminated soil texture, content of heavy metals in the soil and soil pH, was the aim in the investigation. Acidification of damaged soil was corrected by calcium carbonate. Mineral nutrients and organic matter (NPK, dung, earthworm cast, straw and coal dust) were added to damaged soil. Afterwards, the soil was used for oat production. Determination of total heavy me...

The thermochemical transformation of sewage sludge (SS) to biochar (SSB) allows exploring the advantages SS and reduces possible environmental risks associated with its use. Recent studies have shown that SSB is nutrient-rich may replace mineral fertilizers. However, there are still some questions be answered about residual effect on soil nutrient availability. In addition, most previous were c...

Nutrient management practices have huge influence on soil biological health. The present study was conducted during kharif-2021 in the on-going AICRP LTFE after 21 years of continuous application fertilizers and manures to estimate enzymatic activities i.e., urease dehydrogenase activity at different growth stages rice crop. In all treatments, enzymes exhibited higher flowering stage thereafter...
