Zeolite usedin agriculture mainly acts as an ameliorating material of so- ils.The test results show that zeolite can absorb Na~+,SO~= and so on in al- kalization soils,and decrease PH value and alkality,and improve the phy- sical and chemical property of the soils and increase its exchange amount, which makes soils better for plants growing and produetion increase.Thus it gives a new way for alkalization soils improvement.
