Using isotope {sup 36}Cl to study utilization of Cl by crops and distribution and movement of Cl in soil

Technical Report:

Abstract

Results from using isotope {sup 36}Cl show that a large quantity of Cl is absorbed and utilized by spring wheat, cotton and tobacco from the chloride fertilizers. The utilization coefficient of Cl increases with the growing time of plants and reaches peak at mature stage. The utilization coefficient of above plants are 26.72%, 3317% and 26.19% respectively. The absorption and utilization of residual Cl in soil is much smaller than that in fertilizers, and the utilization coefficient is decreasing with the increasing of growth season. For spring wheat, utilization coefficient is 12.7% in second season and 9.3% in third season. The ability of absorbing and utilizing Cl from organic materials by crops is very low and the utilization coefficient is 10% or less, that depends on circumstances. For rice the utilization coefficient is 3.1% in dry land and 24.3% in flooded land. The distribution of absorbed Cl is mainly in stalk, a little in husk and a few in seeds and roots. After irrigating water it is equivalent to 9.1 mm of rainfall in soil, the Cl moves rapidly to depth 10{approx}12 cm. Cl moves faster in porous soil than in clay soil, and faster in horizontal direction than in  More>>
