Soil Fertility And Changes In Fertilizer Use For Intensive Rice Cultivation In The Red River Delta And Mekong Delta Of Vietnam, Jennifer Soong

Independent Study Project (ISP) Collection

Rice farmers in Vietnam’s Red River Delta and Mekong Delta are now fully addicted to using fertilizers to sustain intensive rice production. The introduction of high yielding rice varieties in the late 1960’s brought with it the ability to grow crops continuously throughout year, and the need to supplement natural soil conditions with both organic and inorganic fertilizers. Rice yields have increased rapidly in the past 40 years. If intensive agriculture is to continue producing the high yields that Vietnam has come to expect, however, proper management of fertilizer use must begin now. In this study, three intensive rice fields …
