Abstract/Description: | A laboratory incubation study was conducted to study the effect of organic soil amendments viz., tobacco stalk biochar and tobacco stalk biomass (TS Biochar and TS Biomass) and inorganic soil amendment synthetic zeolite (SZ) on soil reaction, N and K availability status of FCV tobacco grown in Alfisols of Andhra Pradesh. One of the major characteristics of biochar and zeolite are their buffering capacity and enhancing water and nutrient retention. Results revealed that soil pH tend to decrease with the progress of incubation time. The magnitude of increase in soil pH was higher in soil amendments alone over the combination of soil amendments with fertilizers. The increment in soil pH differed between different soil amendments and followed order: 1 t ha-1 TSB+250 kg ha-1 SZ > 1 t ha-1 TSB > 100 % RDF+1 t ha-1 TSB+250 kg ha-1 SZ > 100 % RDF+ 250 kg ha-1 SZ > 100 % RDF+1 t ha-1 TSB > 100 % RDF + 0.5 t ha- 1 TSP. Among different soil amendments maximum available nitrogen was observed in 100% RDF+1 t ha-1TSB. The relatively greater quantity of available soil potassium was recorded by 100% RDF+1 t ha-1TSB+250 kg ha-1 SZ followed by 100% RDF +1 t ha-1TSB. The results suggest that TS Biochar incorporation may have a significant role as liming effect and also in improving the availability of an Alfisol |
