Overview

Excerpt from Seasonal Water and Nitrate Leachings in Relation to Soil and Source of Fertilizer Nitrogen: A Second Report on Windsor Lysimeter Series A For the purposes of comparison, the lysimeter year beginning May 26 (the date of application Of fertilizer treatment) has been divided into four periods. The first, or summer period, is extended to include the last leach ing rain in August. The second, or autumn period, ends on November 25, the date of collection Of leachates for composite analyses*. The third, or winter period, is extended to include the final spring thaw leaching, near the first of April. The fourth, or spring period, ends on May 25, except for 1934, when the soils were removed by May 20 to permit refilling for a fur ther experiment. Data on leaching in relation to rainfall are given in Table 3. These results Show considerable differences in the proportion of rainfall leached from the various soils, for the various seasons, and for the same season in different years. Most Of these differences may be explained in the light of the previous summary Of the distribution Of rainfall from year to year.
