为了有效地开展白浆土改良工作，自1986年开始，作者对白浆上某些理化特性进行了调查。结果表明，白浆土关键问题在于白浆层。主要表现在两个方面：一是该层土壤水分性状不良，有效水不足，只有5.39％，透水能力差，饱和透水系数仅为6.08×10-5cm／s；二是土壤硬度过大，达25kg／cm2以上。由于白浆层土壤出现部位浅，矛盾集中反映在耕层，造成耕层根系有效上层浅，表旱表涝严重，直接混入耕层后，土壤压缩性降低、耕性变劣。白浆上耕层的磷素主要以有机态形式存在，分级磷含量顺序为Fe-P＞Al-P＞Ca-P。磷肥培养试验中的磷约50％-60％转化为Ca-P,10％-20％转化为Al-P，2％-10％转化为Fe-P。
In order to carry out the improvement work of albic soil effectively, since 1986, the author has investigated some physical and chemical characteristics of the white pulp. The results show that the key problem of white soil is white plasma layer. Mainly in two aspects: First, the poor soil water properties of this layer, the effective water shortage, only 5.39%, poor water permeability, saturated water permeability coefficient of only 6.08 × 10-5cm / s; Second, the soil hardness is too large, up to 25kg / cm2 or more. As the white soil layer appears shallow soil, contradictions are concentrated in the plow layer, resulting in upper plow shallow upper layer, table drought serious waterlogging, directly into the plow layer, soil compression decreased, tilling worse. The phosphorus in the top layer of white soil existed mainly in the organic form, and the order of the fractionated phosphorus was Fe-P> Al-P> Ca-P. Phosphorus fertilizer culture experiments about 50% -60% conversion of phosphorus into Ca-P, 10% -20% into Al-P, 2% -10% into Fe-P.
