Abstract

Field capacity and PERMANENT WILTING POINTare used to calculate the amount of available water and generally the amount of water required by plants. Determination of these parameters usually takes much time and on the other hand there is not enough equipment for their analysis in all of the laboratories. Therefore, estimating of some soil physical and chemical properties can provide useful information to obtain the ability of hold moisture by soils. In this study, soil samples from area of Gysvm in Guilan province were taken and transferred to the laboratory and, particle size distribution, organic matter content, pH, particle density, bulk density, FC and PWP were measured. The correlation of FC and PWP with other soil properties was analyzed by using the univariate multiple regressions. The results showed that FC had significant and strong relationship with organic matter and the amount of sand (r=0.8, p<0.01 and p<0.05). In addition, PWP showed significant relationship with silt and organic matter r=0.57, p<0.05). In general, the results showed that for estimation of FC and PWP in this area or similar places, the other soil characteristics, which can be evaluated easier, can be used.
