“…This difference between TN and PP may result from the fact that TN is mainly of organic origin and will, thus, be lighter than PP, which is comprised mainly of P sorbed by sediment material. Knoblauch et al (1942) and Neal (1944) obtained higher ERs for organic matter (4.31) and TN (4.12) than for TP (1.84) in runoff from Collington sandy loam in New Jersey. Recently, Sharpley (1985) reported ERs of 2.00 and 1.56 for organic C and clay in runoff from several soils using simulated rainfall.…”

“…It has been shown by experimental work at the Marlboro Station [KNOBLAUCH, KOLODNY, and BRILL, 1942;NEAL, 1943;NEAL, 1944] and at other locations that cover crops and organic matter additions to the soil reduce runoff and erosion losses. The present study v.'as designed to study the effect of such treatments and the effect of slope length on the rate of runoff during storm periods.…”

In conjunction with the measurement of total soil and water losses from different soil treatments and slope lengths, data were also collected on rate of runoff from four plot areas. These included three 70‐foot slope lengths consisting of untreated, annual cover crop, and annual manure treatments, and one 210‐foot slope on an untreated area. Tabular data are presented for five representative storms showing maximum rates of precipitation and runoff, and the total periods of time during which rain fell and runoff occurred at rates exceeding 0.00, 0.25, 0.50, 1.00, and 2.00 in/hr. The data indicate that: (1) The rate of runoff from any particular condition varies with rainfall intensity and with season. (2) Increased slope length under conditions of this study had no consistent effect on rate of runoff. (3) Soil organic matter additions either from cover crop or manure were effective in reducing runoff rate during the growing season. (4) The relative effectiveness of organic matter treatments decreased as rainfall intensity increased. (5) Winter cover crops, under certain conditions, may greatly increase runoff rate from winter storms. (6) Soil‐moisture content at the beginning of the storm has much less influence of rate and amount of runoff from this sandy soil than is the case on many other soil areas.

“…For example, Massey and Jackson 6 7 found, as an average for four locations in Wisconsin, that the eroded material contained 2.1 times more organic matter, 2.7 times more N, 3.4 times more soluble P, and 19.3 times more exchangeable K than the soil that yielded the eroded material. Knoblauch et al 68 found that the eroded material averaged 4.2 times higher in organic matter, 3.9 times higher in N, and 1.52 times higher in P than the soil of the plow depth on a Collington sandy loam on a 3.5% slope planted to vegetable crops in New Jersey. The ratio previously cited in Table 4 show the P enrichment ratios for some eroded sediments in Iowa.…”
