Variation in content of available P and K (Bray I) in soil samples from a cropped N, P, and K fertility experiment over 8 years



Variation in content of available P and K (Bray I) in soil samples from a cropped N, P, and K fertility experiment over 8 years



Communications in Soil Science and Plant Analysis 11(10): 993-1004



Plots from a N, P and K field fertility experiment were soil sampled each spring and fall from 1971 to 1979 to study the effect of cropping and different rates of added P and K on the content of available soil P and K (Bray I). P and K fertilization was in the spring after soil sampling and before planting in 1971, 1972 and 1973 and in the fall after sampling in 1974, 1975, 1976, 1977 and 1978.
