| Summary: | Cultivating pastures in cut and carry (CC) and grazing (GZ) systems may potentially affect nutrient availability in soil and
nutrient concentration of grass vegetation. The objective of this study was to compare soil nutrient availability and grass
nutrient concentration between the two pasture systems namely CC and GZ, which was conducted in Universiti Putra Malaysia
Bintulu Sarawak Campus (UPMKB). Twenty-nine (29) blocks were established across the systems, sampling for CC pasture
was done by systematic grid sampling method and sampling for GZ pasture was based on the location of waterways and
manure deposition respectively, for CC and GZ systems. The findings reveal that the CC system had significantly higher pH,
TOC, TN, AP, AFe, and AMn values (except CC1 and CC5) compared to GZ, which had very strongly acidic pH with
lower TN and AP. A reason for this observation could be due to difference in fertilizer management practices, the GZ, only
relied on animal excreta as source of nutrients. Consequently, the repeated application in CC system had helped higher nutrient
uptake by grasses that resulted in production of high-quality Napier grass. The soil nutrient status in intensive GZ system
should be monitored closely to prevent losses of fertility and fertilization programme should be implemented to supplement
the organic nutrients provided by the animal excretes. |
