Influence
of Agricultural Lime in Alleviating Acidity Level of Various Acid Soils
Authored by Dipendra Chaudhari
Influence of agricultural lime in acidity
level, macro-nutrients (P&K) mineralization and plant growth in various
acid soils were investigated inside glass house in French bean (Phaseolus
vulgare). The experiment underwent from 24th July to 8th October 2017. Liming
of five different acid soils (Pine Forest Soil, Black Soil, Red Soil, Swampy
Soil and Cultivated Soil) were done as per the doses recommended by SMP buffer
method. Plant height was measured, and the soil was sampled to 15 to 25cm
depth, initially and then at interval of 15 days till 75th day of treatment
application. The experiment was carried under Completely Randomized design
(CRD). Data of soil parameters (soil pH, P & K availability) and plant
parameter (plant height) at different times were critically analyzed for
significance test at 5% level of significance. Desirable pH range for crop
cultivation was achieved after 30 days, however desirable soil pH range was
only achieved after 45-60 days of lime application. Most significant increase
in pH of Red soil was observed after 15 days of treatment application (from pH
4.9 to 6.2) and gradually increased up to 7.3 in 75 days, highest among all
other soils. mineralization of soil K in swampy soil was statistically significant
and superior among all types of soil/treatment considered for study followed by
black soil cultivated soil as most superior in terms of P-mineralization for
all cases followed by black soil French bean seemed much responsive to Normally
Cultivated Soil while the least responsive to Pine Forest Soil.
