“…It has been shown in earlier studies that the net N mineralization rate of manure is negatively correlated with the soil clay content (Castellanos and Pratt 1981;Chescheir et al 1986;Sørensen and Jensen 1995a and b). The three main reasons for this phenomenon are (i) fixation of NH 4 + -N into the interlayer spaces of clay minerals (Nieder et al 2011), (ii) entrapment of organic N compounds in soil aggregates inaccessible to microbes and (iii) physical protection of the microbial biomass in the soil structure (Van Veen and Kuikman 1990). According to Magdoff (1978), N mineralization from added organic materials can also be affected by the rate of mineralization of native soil organic matter (OM).…”

“…This indicates that the Alfisol exhibited a higher liberation of residual N to the crop compared with the Vertisol, which is associated to the type of clay prevailing in both soils (Nieder et al, 2010) and the dynamics of N in each soil in the presence of plants where the delivery capacity of soil N could be higher than the result generated by an analysis of available N prior to crop establishment as pointed out by Fernández (1995) and Hirzel et al (2007) for maize in the absence of fertilization. compared with the control without N. Crop N uptake as a residual effect of applied N was between 29.3 and 33.9 kg N ha -1 in Alfisol and 28.3 and 45.8 kg N ha -1 in Vertisol compared with the control in both cases, no significant difference existed that corroborates significance between their means (P > 0.05).…”

“…Mean mineralized N-NH4 + concentration in the Vertisol was 54.15 mg kg -1 at 160 kg N ha -1 rate applied in the previous season for 21 d incubation (Figure 1b). The differences in the amount of mineralized N in both soils respond to higher N uptake of the previous season in Vertisol (Hirzel and Rodríguez, 2013) and to the dynamics of N-NH4 + adsorption and desorption in the dominant type of clay (Montmorillonite) in the Vertisol under incubation conditions (Nieder et al, 2010), which in turn is mediated by soil biomass (Jensen et al, 2000;Sainz et al, 2004;Sahrawat, 2006) as well as the degree of K saturation (Table 1) in the intermediate layers of clay minerals (Nieder et al, 2010). The submerged condition of rice paddy soils is also a factor that influences the level of soil N-NH4 + mineralization; however, it can lead to contradictory conclusions about the extent of mineralization.…”

An important N source for rice (Oryza sativa L.) is mineralization of the organic forms of N present in the soil. The correct N determination will help to optimize the amount of fertilizer used. Our objective was to calculate an index that relates crop N uptake from previous N fertilization and N mineralized in rice paddy soils. To do so, we used two rice paddy soils, Alfisol and Vertisol, in Chile under different anaerobic incubation times and temperatures. We determined both soil mineralization and residual effect of fertilization in the previous season under field and laboratory conditions in an Alfisol and a Vertisol managed with a rice monocrop. Anaerobic incubations were carried out at 20 and 40 ºC; and at five different times (0, 7, 14, 21, and 28 d). Our results indicate that residual fertilization affects N mineralization, which increases in both paddy soils when compared with the control without N. In the Alfisol it fluctuates between 6.1 and 13.3 mg N-NH4 + kg -1 , whereas in the Vertisol ranged between 18.4 and 28.0 mg N-NH4 + kg -1. Crop N uptake as a residual effect of applied N ranged between 29.3 and 33.9 kg N ha -1 in the Alfisol and 28.3 and 45.8 kg N ha -1 in the Vertisol. Thus, N mineralization is mainly affected by incubation time, temperature, and N fertilization rate of the previous crop season; it can be represented by quadratic models with high determination values, R 2 = 0.73 ** and R 2 = 0.78 **, for Alfisol and Vertisol, respectively. Moreover, we found that the best incubation time and temperature were 7 d at 20 °C and 21 d at 40 °C, for the Altisol and Vertisol, respectively. In addition, there are potential savings in the next rice crop season from 0.86 to 0.43 kg N applied for each 1 mg N kg -1 mineralized in the Alfisol and Vertisol, respectively. We conclude that crop N uptake was related to mineralized N and that the equation here developed that relates them is a good predictor to optimize fertilizer use in rice paddy fields.

“…However, when K + was applied after ammonium containing fertilizers total yield was significantly higher with K1. Although continuous uptake of K + ions reduced the K + concentration and diminished the blocking effect on the release of NH 4 + (Nieder et al 2011) the K + concentration in the treatments with K2 was still too high to overcome the blocking effect. Therefore the statement of Pasda et al (2001) that N fertilizers combined with DMPP may improve yields of agricultural crops and vegetables must be observed in more details.…”

“…If the K + concentration of the soil solution is high or increased by K fertilizer application, it can be expected that the interlayer space is also saturated with K + (Scherer 1982), resulting in a decreased NH 4 + fixation. Otherwise K + may impede the release of NH 4 + ions, which may be due to the blocking effect of K + ions (Nieder et al 2011). Therefore, when applying NH 4 + stabilized fertilizers interactions between NH 4 + and K + ions should be taken into consideration.…”

Ammonium fixation and release by clay minerals as influenced by potassium

It is postulated that stabilized ammonium fertilizers improve fertilizer-N utilization by crops, leading thus to higher yields with the same fertilizer rate, especially on sandy soils. However, it must be taken into consideration that in clayey soil at least a part of the NH 4 + ions may be fixed by 2:1 clay minerals, thus delaying the effect of the N fertilizer. Because NH 4 + and K + have similar size and valence properties and therefore compete for the same non-exchangeable sites of 2:1 clay minerals, we investigated the influence of time and K + application rate on both fixation and release of NH 4 + . Fixation of NH 4 + ions was higher when K + was applied after NH 4 + , while the influence of the K + application rate was less pronounced. Mobilization of non-exchangeable NH 4 + was retarded when K + was applied at the high rate after NH 4 + . At the first harvest yield formation of ryegrass was neither influenced by the amount as well as the application time of K + , because plant available N was not growth limiting, while yield of the second harvest was significantly higher with the low K + application rate after NH 4 + . After the second harvest the blocking effect of K + on the release of non-exchangeable NH 4 + was attenuated and the highest yields of the third cut were reached in the treatments with the high K + application rate after NH 4 + . Total dry matter yield was highest when K + was applied at the low rate after NH 4 + . Our results show that K + governs fixation and release of non-exchangeable NH 4 + , which should be taken into consideration when applying ammonium containing N fertilizers like ammonium sulfate, ammonium sulfate nitrate and ENTEC. Thus K + can affect N availability when N is applied as NH 4 + in both the short and long term.
