“…Treatments Control, M 4 and M 5 presented a decrease in N MN concentration in the last week of incubation generating differences between them (p < 0.05). The behavior of N MN concentration observed in Figure 1 is similar to that reported by Laos et al (2000), Mohanty et al (2013) andSan Martín et al (2016), who observed a steady increase in N MN concentration with mild lows between weeks. These results also were similar in all treatments to the results of Masunga et al (2016) using different amendments used in agriculture from animal and green origin.…”

In thermoelectric industry, synthetic gypsum and coal ash are generated as industrial by-products. The objective of this work was to evaluate the effect of different mixtures of synthetic gypsum and coal ash on N mineralization in an Alfisol. Nitrogen mineralization was evaluated by soil incubations under controlled conditions and potential mineralization using the nonlinear first order kinetics model Nm t = N 0 [1 -℮ (-kt) ], where Nm t is the mineral N accumulated at a specific time, N 0 is the potentially mineralizable N, k is the mineralization rate, and finally t is the incubation time. Treatments consisted of different mixtures of synthetic gypsum, coal ash and urea (M 1 : 50% synthetic gypsum, 50% coal ash, M 2 : 50% synthetic gypsum, 35% coal ash, 15% urea, M 3 : 45% synthetic gypsum; 40% coal ash, 15% urea, M 4 : 65% synthetic gypsum, 20% coal ash, 15% urea, M 5 : 55% synthetic gypsum, 30% coal ash, 15% urea). Each mixture was applied to the soil at 2 t ha ). Where the highest and lowest k were determined in M 5 (k = 0.44990) and M 3 (k = 0.04470), respectively. Mixtures of synthetic gypsum, coal ash and urea increased N mineralization over mixtures without urea. Respect N potential mineralization, in some cases N 0 and k values would respond more to the fit of the mathematical model employed than to the biological process.

“…Concern the fertilizer treatments, NH 4  -N concentration increased in the leachate solution to a peak at 24 days after starting, but differ in their values as affected by fertilizer treatments, then declined to very low levels at about 96 days of starting (DAS). Confirm these results (Nagarajah et al [17], Hanan [18] and Zhang et al, [19] who found that the decrease in NH 4  -N over the initial values at later stages was attributed to crop uptake, gaseous loss of NH 4  -N as NH 3 and incorporation into the body tissue of micro-organisms. Inorganic fertilizer treatments (F 1 and F 2 ) gave higher NH 4  -N concentration under all soil moisture regimes as compared with organic fertilizer treatment alone (F 4 ).…”

“…The obtained results are in good harmony with those of [15], [18], [22], [19] who stated that intensity of nitrogen leaching depends on the rate of percolating of water though the soil. They also found that loss of NO 3  -N by leaching increased by increasing the amount of soil moisture levels, and the interaction of fertilizers (sources and rates) and water regimes gave a highly significant increase in total losses of NO 3  -N in the leachat solution.…”

“…Generally, the F 3 (organic in combination with inorganic fertilizers) was the best in affecting the concentration of the nutrients in soil solution. In this concern Deka Meldhi et al, [20] stated that the addition of organic matter particularly was reported to accelerate the process of reduction in soil, by decreasing the redox potential and increasing PCO 3 . Manganese (Mn): Results presented in Table (4) indicate that Mn concentration increased gradually and reached a peak at about 24 DAS.…”

“…Besides, the applied fertilizer, particularly nitrogen, may incur looses due to changes in water stress, and its use efficiency may also differ. Rice growing under different soil water level prevailing under rain fed conditions has largely been ignored [1], [2], [3]. The supplementary and complementary use of organic manure and chemical fertilizers will augment the efficiency of both substances to maintain a high level of soil productivity and rice production [4].…”

A pot experiment was conducted in the greenhouse of NRC, Dokki, Giza, Egypt, using clay loam soil to study the effect of different moisture regimes (M1, M2 and M3) and fertilizer treatment(F0, F1, F2, F3, and F4) on electrochemical change and concentration of some nutrients in the leachate solution during growing period of rice plant (variety Sakha 102). The important results could be summarized in the follows: PH values showed the highest decreases under all the fertilizer treatments when the moisture regime of M1 was used followed by M2 and M3 in descending order. Furthermore, pH values showed higher decreases when the fertilizer treatment of F3 was used followed by F4, F2, F1 and F0 in decreasing order. Under all soil moisture regimes and fertilizer treatment Eh values sharply decreased during the 12 days after starting (DAS), then they decreased to the lowest values at 24 DAS. The soil moisture regimes decreased Eh values in soil solution during the growth period of rice plants. The highest decreases were obtained under soil moisture of M1 followed by M2 and M3 in descending order. The greatest decreases of Eh values were obtained by using the fertilizer treatment of F3 followed by F4, F2, F1 and F0 in descending order. Results showed that , P, K+, Fe++ and Mn++ concentrations in soil solution were higher in the early stages of rice plans and reached a peak at 24 days after staring (DAS), then the concentrations of all the studied nutrients gradually decreased with increasing the growth period. Inorganic N-fertilizer treatments (F1 and F2) gave higher nutrients concentrations under all soil moisture regimes as compared with N-organic fertilizer treatment alone (F4). Combination of organic and inorganic fertilizer (F3) gave the higher nutrients concentration in the leachate solutions followed by fertilizer treatments of F2, F1, F4 and F0 in decreasing order. The highest values of , P, K+, Fe++ and Mn++ concentrations were obtained at 24 days after starting (DAS) by using the fertilizer treatment of F3 under soil moisture regime of M1 (F3 M1¬) followed by F3M2 and F3M3 in decreasing order, while the lowest values were obtained at 72DAS under soil moisture regime of M3 and unfertilized treatment F0 (M3F0).

High nitrogen (N) rate often leads to low yield of rice due to lodging and mutual shading. This study was conducted to ascertain whether silicon (Si) could enhance yield response of rice to higher N rate by enhancing rigidity of plant parts and improving photosynthesis. The effects of Si and N on crop growth, photosynthesis, N use efficiencies and yield of rice were investigated during wet season (June to November) in sub-humid tropical region of India. An increasing trend in crop growth rate with Si at all levels of N was observed. Silicon reduced the flag leaf angle making the leaf more upright and enhanced flag leaf N content. Leaf chlorophyll concentration and single leaf photosynthesis rate were higher with Si compared to without Si at flowering stage. Both N and Si significantly affected panicle number and grain filling.Application of 200 kg SiO 2 ha −1 and 100 kg N ha −1 produced the highest number of panicle per square meter, filled grain per panicle and yield. Significant yield increases ranging from 8.2-16.9% were observed with Si compared to without Si. Both N and Si treatments had significant effects on N uptake and N use efficiency. Agronomic N use efficiency and N recovery efficiency were higher with Si compared to without Si. The highest physiological N use efficiency was recorded with 200 kg SiO 2 ha −1 and 80 kg N ha −1 . Silicon may enhance yield response of rice to higher N rate by improving source (photosynthetic) capacity and sink (reproductive organ) strength.Abbreviations: DMA, dry matter accumulation; FL, flowering; HI, harvest index; MT, maximum tillering; NRE, nitrogen recovery efficiency; NUE a , agronomic nitrogen use efficiency; NUE p , physiological nitrogen use efficiency; PFP N , partial factor productivity of nitrogen; PI, panicle initiation; PM, physiological maturity.
