Soil is the basic material on the earth where life begins, so it holds the whole bag of nutrients in it. Plants uptake directly or indirectly from soil, perhaps need to be checked properly. Soil test can determine wide variety of soil. It is used to diagnosis of plant problem.
\nGenerally soil is tested for-
\nPH in soil:
\nPH scale contains 0-14 .
\nwhere, 0-6 indicates acid soil and 8-14 indicate basic soil. around 7 indicates neutral in nature.
\naccording to soil test PH is determined and it is modify as per our convivence.
\nMacronutrients:
\n1.NITROGEN:
\nAs we know nitrogen is the main component in plant structure, it is needed in the larger amounts.
\nNitrogen is determined by khjeldhal method which is given by subbaiah .
\nThis test is based mainly on titration. Due to change in the colour nitrogen percentage is known
\nby knowing nitrogen percentage, we apply fertilizers.
\n2.POTASSIUM:
\nPotassium test is done in the flame photometer.
\nThe movement of ions indicate the percentage of potassium.
\nSo, as per need muriate of potash is applied to the soil.
\n3.PHOSPHOROUS:
\nPhosphorous is determined by spectrophotometer.
\nHere, we find due to intensity of different rays in spectrophotometer.
\nAccordingly, we supply chemical fertilizers DAP, SSP, MAP.<\/p>\n
Likewise, soil can be tested differently for different nutrients.<\/p>\n
IMPORTANCE OF SOILTESTING:
\nIdentifies the deficiency of different nutrients.
\nImproves productivity in right way.
\nIt mainly gives information about the percentage of nutrients to be applied.
\nTo minimize fertility usage.
\nTo avoid soil degradation<\/p>\n","protected":false},"excerpt":{"rendered":"
