“…By definition, the term 'fertilizer' refers to a soil 1 3 amendment that guarantees the minimum percentages of nutrients (at least the minimum percentage of nitrogen, phosphate, and potash). An "organic fertilizer" refers to fertilizer derived from non-synthetic organic materials, including plant and animal by-products, rock powders, seaweed, inoculants, sewage sludge, animal manures, and plant residues (Benton and Jones 2012) produced through the process of drying, cooking, composting (Dadi et al 2019), chopping, grinding, fermenting (Mario et al 2019) or other methods (Thanaporn and Nuntavun 2019). Organic and inorganic fertilizers have been used for many centuries (Erisman et al 2008), whereas chemically synthesized inorganic fertilizers were only widely developed during the industrial revolution.…”

Purpose Rapid nutrient depletion in soils is one of the major problems that affect food production and food security in Sub-Saharan Africa. Studies have linked the growth of food crops with seasonal variation and differences in weather conditions. This study was conducted to assess the effects of various organic fertilizer formulations (OFFs) on the growth and yield of selected crops (Zea mays L.; Glycine max, TX 114 and Dioscorea rotundata Poir) during rainy and dry seasons to ensuring climate-smart agriculture. Methods The OFFs used were plant-based (PB), animal-based (AB), rock-based (RB), organic mixture (OM-mixture of PB, AB and RB), synthetic/chemical (SC) while ordinary compost without fortification served as control. Effects of OFFs on growth parameters (number of leaves, plant height, stem girth, leaf area, and crop yield) of maize, yam and soybeans were assessed in plot experiments across the two seasons. Results The RB gave highest growth performances in maize and soybean plots at both seasons when applied at 2.5 t ha −1 . It also improved yam growth when applied at 2.5 t ha −1 (rainy season) and 3.0 t ha −1 (dry season) more than any other fertilizer. The largest yield of maize in the dry season was obtained from plots with PB at 2.0 t ha −1 . The AB at 2.0 t ha −1 gave the largest soybean yield in the rainy season. Conclusions Organic fertilizers enriched especially with rock-based and plant-based materials have the potential to ameliorate the threat of climate change and seasonal variation to food security.

“…The hoses were connected to another plastic container filled with 50% water to accommodate the safe release of exhausted gas. The design of this low-cost digester was adopted from a study by Chontal et al with minor modifications [12]. The pretreated dried seaweed biomass was mixed with molasses (1 L/ton) and subjected to anaerobe fermentation with EM 4 (1 L/ton) for 40 days.…”

Excessive use of chemical fertilizer could potentially decrease soil productivity by decreasing soil microbiome diversity. In this study, we evaluated the effects of fermented seaweed fertilizer in the soil microbial community of paddy plants (Oryza sativa L.). The paddy seedlings were divided into five groups, control (C0), chemical fertilizer (CF), seaweed fertilizer (SF), chemical and seaweed fertilizer combination 50:50 (CFSF1), and chemical and fertilizer combination 75:25 (CFSF2). The CFSF1 combination showed to be the most effective in inducing plant height (83.99 ± 3.70 cm) and number of tillers (24.20 ± 4.08). After 8 weeks after transplantation, the isolated DNA from each soil treatment were subjected to 16S rRNA (v3–v4 region) next-generation sequencing. The beneficial Acidobacteriota was most abundant in CFSF1. At genus level, the nitrifying bacteria MND1 was seen to be abundant in CFSF1 and also present in other SF treatments. The genus Chujaibacter is highly abundant in CF, which potentially plays a role in denitrification resulting in soil degradation. In addition, the CFSF1-treated soils show significantly higher diversity of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA). The current results could potentially contribute to the utilization of SF as a bioremediator and promoting green agriculture practice by reducing the amount of CF usage.

“…Sustainable practices in the handling of natural resources These contributions are oriented toward the preservation of flora and fauna (handling and consumption), soil improvement practices, organic fertilizers for the sustainable production of crops, handling of natural resources and adequate use and handling of pesticides (Avendaño et al, 2018;Candelaria et al, 2014;Cisneros et al, 2015;Chontal et al, 2019;De Farias et al, 2015;García et al, 2015;Jacinto et al, 2017;Linares et al, 2018;Linares et al, 2017;Llarena et al, 2019;Nikolskii et al, 2019;Ramirez et al, 2016;Vandepitte et al, 2019).…”

Objective: Analyze the contemporary scientific contributions of the Masters and Doctorate Graduate Program in Tropical Agroecosystems (PTA) taught at the Colegio de Postgraduados, Campus Veracruz, facing the current challenges of Mexican agriculture. Design/methodology/approach: A bibliographic search was carried out in SCOPUS and Web of Science, on papers (N = 92) published during 2014-2019 by PTA research-professors. A textual analysis was carried out using Nvivo Software to identify the scientific contributions, based on problematic categories suggested by FAO for Mexico. Results: Scientific contributions are more prolific in relation to the increment of agricultural productivity (66 %), to a lesser extent in sustainable practices (14.9 %), articulation of public policies (10.6%), and initiating in adaptation and mitigation of climate risks (8.5 %). Limitations of the study/implications: Findings excluded publications not indexed in SCOPUS or Web of Science or out of the analyzed period. Findings/conclusions: The PTA shows social relevance in the generation of knowledge, with scientific contributions to the current challenges of Mexican agriculture. However, they have mainly focused on increasing agricultural productivity; this does not allow the achievement of the challenges of the PTA towards research processes aimed at trans discipline. This suggests a new research role that approach disciplinary interfaces.
