Food waste is a vast issue global, including in Malaysia. brings negative impacts, increasing food production costs, impact on human health, and environmental degradation. Malaysian's animal- plant-based diet preferences affected the desired decomposition method as most of methods only allow material to be utilized compost. The objectives this study were understand Malaysians' awareness behaviour component for decomposition. Malaysians usually produce more than animal-based waste. Most have...

Abstract. In response to human population increase, the utilization of acid sulfate soils for rice cultivation is one option increasing production. The main problems associated with such are their low pH values and high content exchangeable Al, which could be detrimental crop growth. application soil amendments approach mitigating this problem, calcium silicate an alternative amendment that used. Therefore, objective study was ameliorate acidity in rice-cropped soil. secondary effects on...

Rubber plantation systems were selected at 3 plantations located nearest pairs 18 total. Data collected included litterfall monthly intervals from October 2016 to April 2017, as well decomposition conditions...

The humic substance consists of acid, fulvic and humin. Humic acid is a useful metal complexing agent, good dispersant, redox agent. showed an auxin-like activity thus promoted root growth development. It positively affected soil’s physical, chemical, biological properties. Hence, indirectly improved plant by chelating nutrients to the plant. However, converted carcinogen compounds in chlorinated water. Still, compound for agricultural purposes. can be produced thermophilic composting,...

This study was conducted at Malaysia Agriculture Research and Development Institute (MARDI), Seberang Perai, Penang (Malaysia), that aims to examine the impacts of application Azolla pinnata on growth performance rice MR 297 variety. The experiment consisted five treatments: PK + (T1); NP (T2); NK (T3); NPK-Control (T4), only (T5). Each treatment had four replicates. experimental design used a complete randomized block (RCBD), all data collected were analyzed using one-way ANOVA with...

Sandy texture soil, a major problem for agriculture requires structure and capacity improvements. However, utilization of soil conditioner may arrest this problem. This research was carried out to investigate the accumulated levels metal ions radionuclides in water, plants following phosphogypsum organic (PG organic) added sandy 23-month 3 cropping seasons. The condition field simulated laboratory using an open leaching column 30-day under constant but different pH leachant. More were...

In Malaysia, the main constraints of rice yield and productivity are infertile soils poor management practices because these characterized by low pH, nutrient availability, organic matter, high exchangeable Al Fe ions, due to rainfall hot temperatures. Thus, an incubation study was conducted determine optimum amount calcium silicate (HmbG brand) improve soil electrical conductivity (EC), Al, available P, cation exchange capacity (CEC) a paddy in Sabah, Malaysia. The Kelawat series (Typic...

Heavy rain falling on land at the upper reaches of Kelantan River, Malaysia, December 2014, had resulted in severe soil erosion and untold damages to croplands. The lower river were heavily silted with infertile materials considered unfit for crop production. A study was conducted explain why flood phenomenon occurred, determine physico-chemical properties sediments Plains propose measures mitigation. Results showed that characterized by presence quarts, mica, feldspars, kaolinite, gibbsite...

The Malaysian government has been challenged with handling unmarketable vegetables and fruit waste that pollutes the environment emits greenhouse gases, mainly methane nitrous oxide. These gases have contributing to climate change. In contrast, these wastes consist of high moisture readily biodegradable nutrients can serve as perfect substrate rate for fermentation. valuable contained in produce liquid organic fertilizers (LOF), which help improve soil’s physical, chemical, biological...
