This article studied the influence of long-term localized fertilization on distribution of soil aggregates and phosphorus forms in fluvo-aquic soil.The results showed that:(1)The main weight body of fluvo-aquic soil aggregate was 0.25~5 mm(60.72%~77.99%),followed by >5 mm,the lowest was <0.25 mm(7.09%~13.68%).Soil aggregate(0.25~5 mm)weight proportion of inorganic fertilizer was 60.72%,it was significantly lower than other treatments(71.5%~77.99%),whereas >5 mm aggregate weight proportion was significantly ...
