REDUCTION OF BIODEGRADABILITY OF UREA-CROSSLINKED STARCH AS SLOW RELEASE FERTILIZER UNDER SOIL CONDITIONS

Pengurangan kadar biodegradasi yang pesat bagi urea-silang kanji (UcS) filem adalah mungkin melalui penambahan alkali kraft lignin. Ujian awal perkuburan tanah telah mengesahkan ~ 80% (berasaskan kanji) adalah lebih biodegradasi bagi filem UcS di dalam tanah tidak steril berbanding tanah steril s...
