Abstract
Available P and K status in a soll after six crops was assessed in the Long Term Fertilizer Experiments conducted at Coimbatore. The availability of P was changed by various fertilizer doses. There was depletion of available P from the control plats. As the the rate of P application increased. the availability also Increased giving rise to a quadratic equation of Y= 2.632 + 0.17824X0.0006 X. The available K was depleted over years except in 150% NPK dose (based on soil test) treatments, and FYM applied plots. A positive and significant correlation (R2 = 0.997) was obtained which gave a quadratic equation in the form of V-450.75 +1.365X0.0041 X*.
