“…This result corroborates with many other studies that suggested low productivity of the rice-wheat system attributable to decline in nutrient availability or nutrient imbalances because of the inappropriate fertilization practice (Timsina and Connor, 2001;Bhandari et al, 2002). Low SOM content and crop yield in rice-wheat systems with the long-term use of recommended dose of NPK was also observed in some field studies potentially due to unavailability of other essential nutrients (Nambiar 1994;Abroal et al, 2000;Yadav et al, 2000). 384.5 †T1 = no added nutrients; T2 = N only application; T3 = N and P application; T4 = N and K application; T5 = NPK (recommended rate); T6 = N only in rice and NPK in wheat (recommended practice); T7 = 1/2 N of recommended practice; T8 = half NP; T9 = farmyard manure (10 Mg ha -1 for each crop).…”

“…Balanced nutrient supply through chemical and organic sources can improve SOM accumulation and increase crop yield in low fertility environments of South Asia (Yadav et al, 2000;Regmi et al, 2002). A study in a rice-wheat system in Parwanipur, Nepal revealed that treatments receiving organic sources of nutrients increased SOM by 18% to 62% compared with the NPK treatment (Gami et al, 2000).…”

Balanced nutrient supply is important for the sustainable crop production. We evaluated the effects of nutrient management practices on soil properties and crop yields in rice (Oryza sativa L.) -rice -wheat (Triticum aestivum L.) system in a long-term experiment established at National Wheat Research Program (NWRP), Bhairahawa, Nepal. The experiment was designed as a randomized complete block experiment with nine treatments and three replications. Treatments were applied as: T1-no nutrients added, T2-N added; T3-N and P added; T4-N and K added; T5-NPK added at recommended rate for all crops. Similarly, T6-only N added in rice and NPK in wheat at recommended rate; T7-half N; T8-half NP of recommended rate for both crops; and T9-farmyard manure (FYM) @10 Mg ha -1 for all crops in rotation. Results of the study revealed that rice and wheat yields were significantly greater under FYM than all other treatments. Treatments that did not receive P (T2, T3, T7, T8) and K (T2, T4) had considerably low wheat yield than treatments that received NPK (T5) and FYM (T9). The FYM lowered soil pH and improved soil organic matter (SOM), total nitrogen (TN), available phosphorus (P), and exchangeable potassium (K) contents than other treatments. Management practices that ensure nutrient supply can increase crop yield and improve soil fertility status.

“…Since impermeable soil layer in Buru's paddy field has not been formed, in dry season submerged paddy soil dried up which in turn aerobic condition induce biological activity to decompose organic matter. Low soil organic matter explained the fact that organic matter application is very limited (Yadav et al, 2000) since the farmer in Buru mixed organic matter only recently.…”

Agricultural productivity in Buru Island, Maluku is threatened by tailings which are generated from formerly gold mine in Botak Mountain in Wamsait Village. Gold that extracted by using mercury was carried out in mining area as well agricultural field. High content of mercury in tailings and agricultural field pose a serious problem of food production and quality; and further endangers human health. The purpose of this research was to determine the contaminant level of mercury in tailing, soil and its accumulation in edible part of some food crops. Soil, tailing and plant samples for Hg testing were taken by purposive method based on mining activities in Waelata, Waeapo and Namlea sub district. Six soil samples had been analyzed for their chemical properties. Total mercury levels in tailings and plants were measured by Atomic Adsorption Spectrophotometer. This study showed that agricultural field where tailings were deposited contained Hg above the threshold but agricultural area which is far from hot spot did not. Most edible parts of food crops accumulated mercury more than Indonesian threshold for mercury content in food. This evidence explained that tailings deposited on the surface of agricultural field had an impact on soil quality and crop quality. Tailing accumulated on soil will decreased soil quality since naturally soil fertility in agricultural field in Buru is low.

“…For example, red clover manure increased and maintained higher bacterial and fungal biomass and high rates of enzyme (arylsulphatase) activity compared to control treated with chemical fertilizer [9]. Collectively, green manure or organic fertilizer was equally as well in improving soil nutrients and crop production as chemical fertilizer [10], but more environmentally friendly, playing a significant role in sustainable agriculture.…”
