  4. Soil carbon and nitrogen changes in long-term continuous lowland rice cropping por Pampolino, Mirasol F., Laureles, Eufrocino V., Gines, Hermenegildo C., Buresh, Roland J.

    Publicado 2008
    “…We sampled four long‐term experiments in the Philippines, with two or three rice crops grown each year with continuous or near‐continuous soil submergence, to determine the effect of fertilizer management on long‐term changes in soil C and N and on C and N balances. Soils were an Aquandic Epiaquoll, an Entic Pellustert, and a Typic Pelludert; soil pH ranged from 5.9 to 6.7. …”
