“…Despite this rich endowment of agro-based resources, the sector has witnessed stunted growth; this is evident as less than half of the cultivable or arable lands are engaged for agriculture, mostly at the subsistence level using primitive tools with attendant drudgery and low yield [ [4] , [5] , [6] , [7] ]. Likewise, the issue of food insecurity persists, compounded by the enduring challenge of low economic capacity among farmers; the contribution of agriculture to aggregate welfare has recorded little effect [ 4 , [8] , [9] , [10] , [11] , [12] ]. With the agricultural sector's substantial contributions to gross domestic product (GDP) and its potential for employment generation, it is imperative to emphasise that adequate investment can boost growth and development in the long run.…”

“…Soil fertility in sub Saharan Africa has continued to decline mainly due to nutrient mining [ 1 ], removing more nutrients from the soil through crop harvest and soil erosion [ 2 ], than is replaced through addition of organic and mineral fertilizers and other recommended management practices [ 3 ]. Nutrient mining, a practice used by smallholder farmers to practice continuous cropping without adding organic fertilizers or other organic sources of nutrients throughout cropping season, is a major problem concerning soil productivity deterioration [ 4 , 5 ].…”

Background Soil fertility decline due to nutrient mining coupled with low inorganic fertilizer usage is a major cause of low crop yields across sub-Saharan Africa. Recently, biochar potential to improve soil fertility has gained significant attention but there are limited studies on the use of biochar as an alternative to inorganic fertilizers. In this study, we determined the effect of maize stover biochar without inorganic fertilizers on soil chemical properties, growth and yield of tomatoes (Solanum lycopersicum L.). A field experiment was conducted in 2022 for two consecutive seasons in Northern Uganda. The experiment included five treatments; inorganic fertilizer (control), biochar applied at rates of 3.5, 6.9, 13.8 and 27.6 t ha−1. Results In this study, maize stover biochar improved all the soil chemical properties. Compared to the control, pH significantly increased by 27% in the 27.6 t ha−1 while total N increased by 35.6% in the 13.8 t ha−1. Although P was significantly low in the 3.5 t ha−1, 6.9 t ha−1 and 13.8 t ha−1, it increased by 3.9% in the 27.6 t ha−1. Exchangeable K was significantly increased by 42.7% and 56.7% in the 13.8 t ha−1 and 27.6 t ha−1 respectively. Exchangeable Ca and Mg were also higher in the biochar treatment than the control. Results also showed that plant height, shoot weight, and all yield parameters were significantly higher in the inorganic fertilizer treatment than in the 3.5, 6.9, and 13.8 t ha−1 treatments. Interestingly, maize stover biochar at 27. 6 t ha−1 increased fruit yield by 16.1% compared to the control suggesting it could be used as an alternative to inorganic fertilizer. Conclusions Maize stover biochar applied at 27.6 t ha−1 improved soil chemical properties especially pH, N, P and K promoting growth and yield of tomatoes. Therefore, maize stover biochar could be recommended as an alternative to expensive inorganic fertilizers for tomato production in Northern Uganda.

“…The widespread adoption of chemical fertilizers in modern agriculture has become common. Nonetheless, the excessive application of these fertilizers has resulted in environmental contamination, soil degradation, and soil fertility loss [1][2][3] . Chemical fertilizers can also be harmful and toxic to humans and animals by food, feed, and water as shutter transmitters [4] .…”

This article emphasizes the various contributions of actinobacteria to the well-being of human life on our planet. Agrarian virtues begin with the substitution of chemical fertilizers with bio-fertilizing microorganisms which have a versatile potential for the benefit of soil and plants by playing complementary and interconnected roles. Thus, these microorganisms improve soil health through bioremediation phenomena and the elimination of several non-beneficial microorganisms. In agriculture, these microorganisms can be added to compost as inoculants to speed up the composting process and provide an additional source of beneficial microorganisms for the compost-treated soil. Streptomyces and other actinobacteria can also be used as biotechnological sources of herbicides and insecticides. In the medical and therapeutic sectors, this paper emphasizes the potential of actinobacteria, in particular Streptomyces species, in the production of antibiotics, antioxidant, and anticancer agents, opening up avenues for the creation of molecules with high benefits. In biotechnology, these totipotent microorganisms produce enzymes widely used in several industries, generating considerable revenue. Sporadic data accumulated on these types of microorganisms opens up many new avenues for exploiting these natural biocatalytic resources. Papers published in the last decade have exploded the amount of information that can be put to practical use. To maximize the value of these microorganisms, it would be advisable to create common threads between the themes that bring together the areas of expertise where these microorganisms could potentially be exploited. This bibliographical synthesis is a contribution to the development of a targeted database.
