You can only find BCMU in Loveland Products' Signature brand fertilizers. BCMU consistently delivers even feeding, reliable performance and customer satisfaction, year after year. BCMU ensures optimal quality turfgrass by providing a consistent, uniform slow release of nitrogen. It is carefully balanced to avoid early growth flushes, provide superior color throughout the season, and maintain performance, especially where other products start to fade. BCMU's release is triggered by temperature and microbial activity, which means it works in harmony with plant demand, delivering nutrients when they are required. This makes for highly efficient feeding and promotes the development of a dense root system.
Here, by fusion of synthetic organic chemistry and plant physiology, we report the effect of synthetic DMA, a common phytosiderophore in Poaceae (e.g., rice, corn, and wheat), in a growth experiment using rice as a model plant in calcareous soil. We also describe the development and application of an innovative derivative of DMA as a fertilizer with improved stability and reduced cost.
At 14 days after transplantation (the day of the final Fe-chelate application; 0 days in Fig. 2a), the rice plants without Fe addition (control) showed severe Fe deficiency with SPAD values around 12. In contrast, the SPAD values were around 30 in plants with Fe-DMA, which was significantly higher than the control value (Fig. 2a). Both Fe-EDDHA and Fe-EDTA moderately improved the chlorosis, but Fe-citrate and Fe-DFO were ineffective. With no further application of Fe-chelates to the soil after 14 days, the SPAD values of the leaves of plants supplied with Fe-DMA were significantly higher over the next 5 days, compared with the values of plants supplied with Fe-EDDHA or Fe-EDTA (Fig. 2a, b). However, the SPAD values of plants fertilized with Fe-DMA decreased thereafter, but those of plants fertilized with Fe-EDDHA were enhanced (Fig. 2a). These differences were likely due to variations in the degradability of these chelators in soil. In particular, MAs are readily degraded by soil microorganisms23, but Fe-EDDHA is stable in calcareous soils29. Thus, the total content of Fe-EDDHA in the soils was presumably enhanced by repeated applications. These experiments provided initial evidence of the effectiveness of Fe-DMA application in overcoming Fe deficiency in rice grown in alkaline soils. However, the stability of DMA in soil requires improvement and the expense of DMA synthesis precludes its practical use as a fertilizer.
MAs reportedly chelate Fe as well as other micronutrients41 (e.g., Zn, Mn, and Cu). They also reportedly contribute to Zn absorption42. Consistent with the prior findings, our soil-incubation test revealed that PDMA solubilized Fe, Zn, and Cu in the soil both with and without fertilizer containing micronutrients (Supplementary Table 2). We next analyzed whether application of the chelates enhanced Fe concentrations in rice plants by measuring Fe, Zn, Mn, and Cu concentrations in the newest leaves by inductively coupled plasma optical emission spectrometry. Metal concentrations in leaves were measured at 7 days after treatment to focus on the primary effects of the applications. Soil application of metal-free PDMA enhanced both the Fe concentrations of leaves and SPAD values in a manner similar to that of Fe(III)-PDMA (Fig. 6a, b), demonstrating that sufficient Fe was taken up for chlorophyll synthesis and storage in leaves. Soil application of Fe-EDDHA slightly enhanced SPAD values, but did not raise Fe concentrations in leaves. Presumably, small amount of Fe taken up by Fe-EDDHA was used preferentially in chlorophyll synthesis in the Fe-deficient condition. Soil applications of Zn-PDMA and Zn-EDTA enhanced Zn concentrations (Fig. 6c), although only Zn-PDMA treatment enhanced the SPAD values (Fig. 6a). This treatment also enhance Fe concentrations, compared with control, Fe-EDDHA and Fe-EDTA treatments. The findings imply that a proportion of the supplied Zn-PDMA was converted to Fe-PDMA in the soil because of the high Fe content in the soil, and thus the rice plants absorbed both Zn-PDMA and Fe-PDMA. Mn concentrations were reduced by applications of metal-free PDMA, Fe-PDMA, Zn-PDMA, and Zn-EDTA. The greatest effect was observed for Zn-PDMA (Fig. 6d). Soil application of metal-free PDMA tended to enhance Cu concentrations (Fig. 6e), consistent with the soil-incubation test (Supplementary Table 2).
The facilitation of agriculture in pilot fields with calcareous soil implies the utility of PDMA as a fertilizer. Moreover, the synthesis of a large quantity of PDMA in our laboratory indicates the practicality of industrial-scale production for agricultural use, although its synthesis requires further improvement. Practical application of PDMA also requires its safety to be demonstrated. We have begun a safety investigation, the preliminary results of which show that PDMA does not exert any cytotoxic effects (Supplementary Fig. 11). Thus, we presume that practical application of PDMA will become a reality in the near future.
We found that in Poaceae species, PDMA is transported by transporters such as ZmYS1 in maize, HvYS1 in barley, and OsYSL15 in rice (Fig. 3c). In this study, the superiority of PDMA was demonstrated in rice, a Poaceae member that is highly sensitive to Fe-deficiency stress. Therefore, PDMA is expected to be effective in all other Poaceae plants. In addition, PDMA has the potential for application to non-Poaceae plants, which can use MAs secreted from Poaceae plants via intercropping18,19,44. Another transporter of MAs, AhYSL1, is localized to the epidermis of peanut roots and transports Fe-DMA45, implying that MAs and PDMA can be externally applied. Thus, PDMA is likely to be effective in all plant species, not only Poaceae. Zn deficiency is another major issue associate with crop loss in calcareous soil. Zn-MAs complexes are also considered as the key factor for the acquisition of Zn in Poaceae plants42, and their contribution is also important for Zn translocation within a plant46. PDMA may resolve Zn deficiency and has the potential to be used as a universal fertilizer for micronutrients.
Finally, the development of PDMA appears to involve simply replacing the four-membered ring by a five-membered ring. However, this approach has not been attempted during the 40-year interval since the discovery of MAs3, primarily because practical application of MAs as a fertilizer to alkaline soils has been considered as impossible due to their high cost of synthesis and limited availability from natural sources. Thus, the application of other synthetic Fe chelates to soil has been studied intensively. Here, we rediscovered the power of MAs in that natural DMA is an effective fertilizer in calcareous soil. We subsequently developed practical PDMA. Despite our simple strategy, the development of PDMA offers up the possibility of greening infertile alkaline soils.
Soil acidity is expanding in scope and magnitude across different regions of Ethiopia. About 43% of total arable land in Ethiopia is affected by soil acidity. Soil P deficiency is also a major constraint to increase crop yields under acidic soil conditions. Appropriate rate of lime and P fertilizer addition is an important strategy for improving crop growth in acid soils. Accordingly, this investigation was undertaken to study yield response of malt barley to lime and P fertilizer application. The experiment was conducted in 2018 at Holeta Agricultural Research Center (HARC), Robgebeya (RG) and Watabacha Minjaro (WM) Acidic fields that were not reclaimed with lime for the last five years were selected and sampled. The experimental treatments comprised of six rates of lime (0, 1.56, 2.34, 3.12, 3.9, and 4.68 t ha-1) and three rates of P (0, 16.5 and 33 kg ha-1) arranged in factorial RCBD with three replications. Soil and agronomic data were collected and analyzed following standard procedures. Results showed that the soil pH increased and exchangeable acidity reduced after amending the soil with lime. Interaction of lime by P fertilizer at the rate of 3.12/16.5, 3.12/33 and 3.12/16.5 (t ha-1/kg ha-1) at HARC, RG and WM, respectively resulted in statistically better yields compared to the other treatment combinations. Therefore, it is recommended that 3.12 t ha-1 lime by 16.5 kg ha-1 P fertilizer are good combination for production of malt barley in Welmera District.
