Study for find out the short-term dynamics of applied fertilizer. In a soil pit a data logger system connected to tensiometers and TDR was installed up to a depth of 3.5m under pueraria in an agroforestry system (cupuacu, peach palm, Brazil nut, urucum). After a rainfall event, the soil water suction at 0.1m depth increased immediately, and fast responses were seen even up to a depth of 0.9m. This result may indicate that nutrients may be leached very fast even in these soil with high clay contents. The N concentrations in the soil solution relevantly increased at 0.1m depth during the same time period, as shown for peach palm. First, the ammonium concentrations increased, but nitrate contents followed rapidly indicanting a fast nitrification in the...
