This paper deals with the nutrient features of seabeach soil in Fujian Province.The nutrients of seabeach soil may originate in special ways,and are rather rich.According to analysis on their 243 profiles,po- tassium status is richest among the nutrient factors in consideration with the mean value of 2.45±0.31% total content and 711±217ppm available content.Besides,the contents of organic substance,total nitrogen and total phophorus are mostly over the medium level.The microelements found in them are also rather rich.Therefore the soils would be the land resources for many uses.The nutrient distribution for seabeach soils in Fujian Prvionce characterized by three main aspects:(1)the nutrient content shows a highly singnificant positive relationship with the contents of soil physical clay (<0.01mm)and organic substance,(2)the nutrient contents appears to be evident differences between regions,i.e.organic substance contents is high- er in harbourbay concealment than other coastal zone,and the nutrient contents are higher in north coastal zones than in south in Minjiang out lets,and(3)in various seabeach soils,the nutrient accumulation in sequence are mangrove seabeach,grass seabeach,bare seabeach for vegetation.

The nine years' experiments in Cangzhou Prefecture showed that sub-chiselling cotton fields every other row that could break the plough pans mightform a loose and solid structure in tilth layer,which can promote rainfall waterinfiltration into soil and increase water storage in deep soil layer.Also,thiscan change the simple erect transportation rules of soil moisture,thus,the side.level transportation process of soil moisture takes place,shereby a special soilenvironment is created in which the aerobic and unaerobic bacterium environ-ment can exist simultaneously.As a result,the accumulation and release ofsoil nutrients can be conducted in synchronization so as to coordinate the rela-tions among soil water,fertilizers,gas and heat to boost an increase in cottonyields.
