Effects of sample depth, and of lime and phosphorus applications on soil test levels in pasture soils
Chapter
Abstract
Depth of soil sampling may affect soil fertility test results. To study this effect, soil samples were taken from pasture soils (Aquic and Ultic Hapludalfs) in October 1985 at three depths before lime and P applications, and yearly thereafter. Pastures were assigned three levels of soil amendment with lime and phosphate fertilizer: 1) none: 2) medium: and 3) high. Climate was humid continental. The average initial soil pH was 4.7, and available P 41, K 418, and Mg 203 kg ha−1. Results showed that the deeper the soil sample, the lower the pH and available nutrients.
