“…Chittora et al [41] mention that, Cyanobacteria is a source of biofertilizers for sustainable agriculture. Biofertilizers can increase the productivity of soils through its role in fixing N from the air [42], mineralization N [43], reducing the nitrogen loss [44], increasing N uptake [45], increasing the availability of N and P nutrients in the soils, releasing hormones [46], promoting plant growth [47], stimulating high expression of nitrate transporter, and increasing yield [48].…”

The existing land characteristics and inappropriate management during intensive agricultural practice on upland, swampland, and paddy field are the factors that causing land productivity to be low and decreasing. Alternative efforts to increase the land, rice, and maize productivities could be carried out through the implementation of Site- Specific Nutrient Management technology based on the RAE parameter. This paper presents thoughts on the opportunities for refocusing RAE- based research on agricultural cultivation technology, and research results that have been done.The research of rice and maize with RAE in the upland and paddy field has resulted in a location-specific cultivation technology package. The technologies that have been produced are single NPK inorganic fertilizer package, the combination of single NPK- compound NPK inorganic fertilizers, the combination of single NPK inorganic fertilizer-organic fertilizer, and combination of single NPK inorganic fertilizer-biofertilizer. By using RAE value, these researches have shown a more effective technology package in comparison with standard technology. The technology devices for determining standard fertilization needed to support the research with RAE parameter as the basis are available. The said devices are Upland, Swampland, and Paddy Soil Test Kit. Refocusing research of location-specific fertilization that explicitly using RAE parameter is relevant to promote sustainable agriculture.

“…Los biofertilizantes pueden ser considerados como enmiendas del suelo, por tratarse de abonos líquidos (Tarigo et al, 2004); estos se generan a partir de la transformación de la materia orgánica proveniente de residuos orgánicos de la producción agrícola y animal, agua y nutrientes minerales (Asadu et al, 2020;Cavalcante et al, 2019).…”

La gestión y tratamiento de residuos orgánicos consiste en la implementación de mecanismos factibles para su aprovechamiento energético y agrícola. Actualmente, se han identificado diferentes tendencias para implementación de métodos alternativos caracterizados por ser tecnologías seguras, eficaces y respetuosas con el medioambiente, entre las que se destacan los biodigestores, de los que se obtiene biogás y bioles con potencial fertilizante líquido, la generación de enmiendas orgánicas del suelo, como lo es el compostaje y la generación de biofertilizantes que pueden suplir el uso de fertilizantes de síntesis. Los residuos provenientes de actividades agrícolas suelen incinerarse o disponerse en vertederos, lo que conlleva la liberación de gases de efecto invernadero, aportando al deterioro del ambiente e incrementando el calentamiento global; además, estos residuos pueden contener organismos patógenos como coliformes, endoparásitos, ectoparásitos y vectores de microorganismos que pueden representar un peligro

“…It can enhance soil aggregation, increase soil organic carbon storage, and promote soil enzyme activity [13,14]. However, organic fertilizers have lower nutrient content and slower nutrient release rates than chemical fertilizers, which may not effectively meet production requirements [15,16]. Therefore, it is necessary to find a way to make up for the deficiency of the above fertilizer.…”

Biostimulants sprayed exogenously boost crop yield and quality. However, the effects of the co-application of biostimulants and fertilizers as base fertilizers in soil are still uncertain. The objective of this study was to investigate the overall effects of reducing N levels in conjunction with the application of biostimulants on the yield formation and N utilization of wheat and maize. Therefore, based on the winter wheat–summer maize rotation system in the modern R&D base of Sichuan Agricultural University, soil enzyme activities, soil inorganic nitrogen dynamic content, crop nitrogen accumulation and transportation, crop yields, and composition were determined. To achieve this, a total of nine treatments were established based on the winter wheat–summer maize rotation system. The experiment included the following treatments: no fertilization (CK0); one-time application of common compound fertilizer (CK1, applied at a rate of 225 kg ha−1); common compound fertilizer as base fertilizer + urea as topdressing fertilizer (CK2, applied at a rate of 225 kg ha−1, base/topdressing, 6/4); biostimulant + common compound fertilizer with 20% or 30% N reduction (jf-20%, jf-30%); biostimulant chelated urea-formaldehyde fertilizer reducing N by 20%, 30%, or 40% (jn-20%, jn-30%, or jn-40%); and biostimulant chelated urea-formaldehyde fertilizer reducing N by 40% and combined with organic fertilizer, thereby totally reducing N by 27% (jny-27%). The results demonstrated that the application of a biostimulant increased the activities of urease, nitrate reductase, and nitrite reductase in the soil of wheat and maize during the flowering stage. At the same time, the amount of residual nitrate and ammonium N in the soil at maturity was reduced. Furthermore, when N application was appropriately reduced, wheat and maize plants treated with jf, jn, and jny showed a significant increase in N assimilation after the flowering stage, resulting in higher N accumulation in the grains at maturity and ultimately improving the yield compared to CK1 and CK2. The combined use of biostimulants also had a significant positive impact on N use efficiency (NUE). During the two-year period, the NUE in the wheat season showed an increase ranging from 6.70% to 24.00% compared to CK1 and from 5.30% to 22.60% compared to CK2. Similarly, in the maize season, the NUE increased by a range of 11.60% to 22.57% compared to CK1 and from 11.78% to 22.75% compared to CK2. Overall, biostimulants enhanced N absorption and transportation by matching crop N requirements in the mid-to-late stages and improved NUE and yield under appropriate N reduction. This study contributes to the design of improved measures for N reduction and yield stabilization in order to promote sustainable agricultural development.
