soil alkalinity

So the relationship between the soil alkalinity and different types of irrigating water was studied.

试验结果表明:用不同类型的非碱化水灌溉后,土壤碱化度有不同程度的增加.

As a result, soil alkalinity rose and farmland lay barren.

结果, 土壤中的碱份增多,农田成了不毛之地.

The variation between soil layers in total salt and total alkalinity is moderate, and rather minor in pH;
