Study on Improved Techniques of Irrigated Brackish Water Soil |
| |
| Abstract: | In the shallow thick-bedded heavy loamy soil the situation that the different amendment agents such as zeolite phospho-gypsm leonardite etc. were used to improve the effects of irrigated shallow underground brackish water(4.7 g/L)on the soil were discussed. The effects of different amendment agents on the soil character of physics and chemistry were evaluated and some recipes of suitable amendment agents were put forward. |
