• • Soils Information <br />Phosphorous variations between the sites do not appear to correlate with growth differ~;nces, but <br />nitrogen appears to show an inverse relationship. Tha[ is, the higher the growth value the lower the <br />nitrogen. The high nitrogen content of MZRS is a residual effect from using ANFO (Ammonium Nitrate <br />and Fuel Oil) as the blasting explosive. Because there is a considerable amount of ammonium nitrate left <br />after blasting, this elevates nitrogen levels. However, in the other samples, the declining N with respect to <br />increasing growth tends to support the conclusion that reduced N stresses the environment to such an <br />extent that successional rates are increased. Unfortunately, this cannot, by itself, explain w:ty the growth is <br />poor on some areas and rich on others, because all the reclamation sites are severely nitrogen limited. [f N <br />was the causal agent then all sites should show equal growth and development rates because all sites are <br />almost equally deficient in N. <br />TABLE IT-1: Routine Soil Test Results <br />Sample # pH Salts <br />mmh°alcm N <br />ppm P <br />ppm K <br />ppm Zn <br />ppm Fe <br />ppm % <br />lime Mn <br />PPm ~~u <br />FPm <br />Organic <br />matter <br />MZR1A 8.4 0.1 2 2.8 54 0.6 13.5 Med 1.6 1.7 0.2 <br />MZR2 7.5 0.1 1 7.8 90 0.9 14.5 Low 3.1 1.1 0.8 <br />MZR3 7.6 0.1 1 14.6 101 1.1 17.1 Low 4.6 1.1 1.1 <br />MZR4 8.1 0.4 1 1.2 73 0.6 16.4 Med 1.2 1.8 0.2 <br />MZR5 8.4 0.4 18 1.8 61 0.6 17.9 Med 3.1 1.5 0.2 <br />Menzer Quarry Amendment Exhibit I Page 9 <br />
