“…The amounts of 15N in the plants derived from ammonium sulfate on July 20 were about 30 to 40% lower than those in dryland direct-seeding as reported by Guindo et al (1994a, b) and Willson et al (1994). The recovery percentages of basal N in this study are in agreement with those in transplanted plants recorded by Shoji et al (1986) and Wada et al (1989Wada et al ( , 1991.

“…Negligible amounts of extractable ammonium-N were observed from July 20 to harvest without the application of topdressed N (data not shown). Shoji et al (1986) and Wada et al (1991) reported that the absorption of basal N by transplanted rice was almost complete at the maximum number of tiller stage, and that of 600 the same time the disappearance of extractable ammonium N in soil was observed. Fertilizer 15N uptake by drill-seeded rice from the pre-flooded N application increased until 21 dafter application (Guindo et al 1994a).…”

Due to high the labor cost, direct seeding is being gradually applied for crop establishment throughout Asia. Recently, the development of the so-called, "controlled release fertilizers" (CRFs) which requires only "one shot dose" of N, has enabled to reduce the cost of labor for the application of topdressed N. Thus, in order to limit pollution and cost, no-tillage direct-seeded lowland rice cultivation accompanied by the use of CRF is being recommended. To evaluate the effects of CRFs on the growth and yield of no-tillage direct-seeded rice, a field experiment was carried out in the northeastern region of Japan in 1993 and 1994. Five N treatments were used: (1) ammonium sulfate (AS) band placement application with seeds at the time of seeding (ASl); (2) AS broadcast application after irrigation (AS2); (3) CRF (LPI00) co-situs application at the time of seeding (Ll); (4) CRF (LPSIOO) co-situs application at the time of seeding (L2); and (5) minus N (MN). The rate of basal N was 60 kg N ha-'. Topdressed N in the ASI and AS2 treatments was applied at 25 d before heading at the rate of 20 kg N ha-'. The highest yield was obtained in the Ll treatment in both years. The number of grains per unit area was affected by the amount of N in the plants at heading. The percentage of filled grains in the L2 treatment was the lowest by about 15 to 20% among the treatments. The recovery percentages of basal N on July 20 were about 20 to 30% in the ASl, AS2, and Ll treatments, and only about 14% in the L2 treatment. About 75 to 80% of basal N was absorbed by the plants at harvest in the Ll and L2 treatments. On the other hand, the plants had absorbed only about 25 to 30% of the applied basal N in the ASI and AS2 treatments at harvest. There was no difference in the N-recovery percentage (based on the amount of released N) between the Ll and L2 treatments. Nitrogen-use efficiency was not significantly different among the treatments. However, higher N-use efficiency was obtained in this experiment than in early studies in the tropics. The agronomic efficiency of CRFs was higher than that of ammonium sulfate.

“…Traditional fertilization approach requires frequent applications and leads to a low recovery efficiency (RE N ) of the rice paddies, which is mostly 30 to 35% (Zhu, 2000); in addition, the agronomy efficiency (AE N ) decreased from 15 to 20 kg kg −1 in 1958 to 1963 to 9.1 kg kg −1 in 1981 to 1983 (Cassman et al, 1996; Witt et al, 1999; Yoshida, 1981). The application of slow‐release fertilizer is considered an effective method of reducing the amount of fertilizer and improving the utilization efficiency of fertilizer (Wada et al, 1991; Inubushi et al, 2002; Nelson et al, 2014; Singh et al, 2004; Xie et al, 2006; Yasmin et al, 2007). Zhang et al (2007) indicated that application with sulfur‐coated urea (SCU) could get greater rice yield than urea at the same N application rate.…”

Slow-release N fertilizer is considered an eff ective method of improving the N use effi ciency (NUE). To investigate yield and N uptake of bowl-seedling machine-transplanted rice (Oryza sativa L.) with slow-release N fertilizer, three fertilizers treatments including slow-release fertilizer blend (SFB), polymercoated urea (PCU), and sulfur-coated urea (SCU), and two fertilizer methods including single basal application (B), and combined with tillering urea (BT) were performed from 2013 to 2014 in Jiangsu Yellow Sea Farm of China. Conventional split fertilization (CK) and zero N treatment (N0) are controls. Yield and NUE improvement was found in PCU under both fertilization methods in both years when compared with the CK. Th e SCU only showed a slight yield increase in 2014, while SFB increased the yields and NUEs under both fertilization methods in both years. Th e BT-SFB got the highest yields as 13.6 and 13.3 Mg ha -1 , as well as increased 7.9 and 10.8% compared with CK in both years, respectively. Th e recovery effi ciency of N was also the highest for BT-SFB with 52.7 and 38.5% for 2013 and 2014, respectively. Th e results indicated that SFB can meet the rice N demand and improve the yield and NUE, and the combined application of tillering urea and SFB was better than that of single basal application with SFB.

“…Yen and Zheng-yin (2007) found that the N-use efficiency, N-agronomy efficiency and N-physiological efficiency increased by 11.4%, 8.32 kg kg -1 and 5.17 kg kg -1 respectively, for rice when a CRF was applied. Wada, Aragones and Ando (1991) reported that the application of controlled-release urea with only half of ammonium sulfate can produce better yield and increase N in rice to almost an equal level. Oil palm (Elaeis guineensis) is an economic crop of Southeast Asian countries.…”

Easily dissolved fertilizers release nutrient in excess amount to be assimilated by plant roots. Some portions these fertilizers leach out from the root zone and adversely impact the environment. Controlled-release fertilizers are more favorable to reduce fertilizer loss, labor cost, and environmental impact. Urea-formaldehyde (UF) was synthesized by polymerization of urea and 40% formaldehyde solution using H3PO4 as a catalyst. Three mole ratios of urea:formaldehyde, namely, 1.0:1.0, 1.5:1.0 and 2.0:1.0 were synthesized. Mineralization of the UF was conducted using eight different mixtures, four different moisture, and four incubation periods. The experiment included soil alone, soil with compost, soil with UF (1.0:1.0), soil with UF (1.5:1.0), soil with UF (2.0:1.0), soil with UF (1.0:1.0) and compost, soil with UF (1.5:1.0) and compost, and soil with UF (2.0:1.0) and compost. Moisture of the mixtures was adjusted to 20%, 40% 60% and 80% water holding capacity (WHC) of the soil. The mixtures were incubated at room temperature for 1, 2, 4 and 8 weeks, the released NH4+ and NO3- were extracted by 1 M KCl and analyzed via a distillation method. Rates of mineralization increased with mole ratio of urea and moisture content of the soil. N loss increased with the moisture content. The best performance for the compromised condition was a mole ratio less than 1.5:1.0 (urea:formaldehyde) at 60% WHC. Availability of UF and serpentine-phosphate for oil palm seedlings was conducted using 10 treatments. The experiment consisted of soil without amendment; soil with Multicote; soil with cow manure; soil with cow manure and urea; soil with cow manure and UF (1.0:1.0); soil with cow manure and UF (1.5:1.0); soil with cow manure, MgHPO4 and UF (1.0:1.0); soil with cow manure, MgHPO4 and UF (1.5:1.0); soil with cow manure, serpentine-phosphate and UF (1.0:1.0); and soil with cow manure, serpentine-phosphate and UF (1.5:1.0). All amended soils increased vegetative growth of oil palm seedlings compared with the non-amended soils. Urea and UF increased the N content in seedling leaves, while Multicote, cow manure, MgHPO4, and serpentine-phosphate increased the Mg content. The best performance was found in the combination of cow manure, serpentine-phosphate and the UF with mole ratio of 1.0:1.0.
