paddy rice soil

The results showed that the degradation rate of mineral oil was promoted by fertilization in alfalfa soil, but not in paddy rice soil.

结果表明，投肥对苜蓿草土壤中矿物油降解有促进作用，但对水稻土壤中矿物油降解无明显作用。

Accordingly, the tested 23 soils, except the paddy rice soil No. 20 from Qianjiang Hubei Province, had low risk of P leaching occurrence.

供试的23个土壤，除了采自湖北潜江的20号水稻土存在比较大的磷素淋失风险，其余土壤发生磷素淋失的风险很小。

A third approach — growing paddy rice aerobically in raised beds — reduces the mobilization of soil arsenite and "can dramatically decrease arsenic transfer from soil to grain," McGrath says.

第三个方法是在培育床上供氧种植水稻，麦格拉思认为，这可以减少动员土壤中的砷，而且“可以大大减少土壤中的砷转移至粮食的量。”
