Nutrient leaching by meltwater runoff as a function of fertilization and tillage method


, : Nutrient leaching by meltwater runoff as a function of fertilization and tillage method. Soviet Agricultural Sciences (8): 6-9

The extent of dissolved-nutrient removal by the meltwater runoff depended on the rate of fertilizer applied. Application at a high rate increased the total amount of nutrients leached by an average of 1.4-2.4 kg/ha; the figure was lower for the area planted to winter crops (by 30-37%), and greater for the fall-plowed land (by 89-97%).
