“…In addition, the short duration of the experiment may also cause a decrease in the impact of organic manure on soil quality. A similar result has been reported by Mokgolo et al [ 44 ]. Rees et al [ 45 ] indicated that the application of CM improved the soil biological properties but did not change the soil organic carbon content and soil physical properties in the three-year study duration.…”

Fruit orchards in the Vietnamese Mekong Delta (VMD) are severely degraded due to many factors, such as low organic matter content, soil acidification, and poor soil management. Organic manures are considered to be a soil conservation measure that decreases soil degradation and acidity. This study aimed to evaluate the impacts of soil organic amendments on the improvement of soil fertility and pomelo productivity. Two soil amendments, namely, chicken manure (CM) and cow dung (CD), were investigated for a period of three years at three pomelo orchards. The soil quality was assessed in two depths (0–20 and 20–50 cm), including the soil pH, electrical conductivity (EC), total nitrogen (Ntot), available phosphorus (Pavail), soil organic matter (SOM), bulk density (BD), and exchangeable cations (Ca, Mg, and K). The results indicated that CD and CM improved soil fertility in topsoil layer (0–20 cm) due to an increase in soil pH, SOM, exchangeable Ca, Ntot, and Pavail. In addition, soil BD significantly reduced after CD and CM were supplied in the three consecutive years of study. The soil quality properties that significantly affected pomelo yield were SOM, Ntot, Pavail, and soil BD. Thus, these soil qualities may be considered as key factors for determining and assessing soil quality in fruit orchards in the VMD. More studies on the influence of organic manures on nutrient uptake and pomelo fruit quality are warranted.

“…Bhatt, et al [67] observed that maize productivity was influenced by the combination of different sources of organic and inorganic soil amendments. Studies have shown the benefits of soil amendments to crop yield, as well as improvement of soil properties [27][28][29][30]. Tahir et al [68] suggested the alleviation of plant stress through nutrient management.…”

Influence of Heat Stress, Variations in Soil Type, and Soil Amendment on the Growth of Three Drought–Tolerant Maize Varieties

Food security in sub–Saharan Africa is threatened by the increasing incidence of heat stress. Therefore, ameliorating heat stress influence in plants is vital for sustainable crop production. A 2 × 3 × 3 × 2 factorial experiment fitted into a completely randomized design with four replications was performed. The factors were heat stress, maize variety, soil amendment, and soil type. The results showed that heat stress exerted a depressive effect on maize growth and yield attributes. It reduced the leaf chlorophyll content, leaf area, plant height, stem diameter, dry biomass yield, and harvest index by 35%, 36%, 41%, 59%, and 78%, respectively. Sandy clay loam soil provided a better maize growth condition than loamy sand soil. Organic manure soil amendment improved maize growth attributes over the mineral fertilizer in the non–heat–stress environment and ameliorated the negative impact of heat stress in the heat–stress environment. The ranking of the attributes identified leaf area, dry biomass yield, stem diameter, and plant height as the most discriminating and representative attributes. These attributes should be considered in maize development projects for heat–stress prone areas. Selection of appropriate maize variety and accompanying soil amendment should be integrated into food security strategy as they influenced maize growth and yield under (non–)heat–stress conditions.

“…The mineralization of these organic materials releases plant-available nutrients (Jacoby et al 2017). Conversely, organic fertilizers boost soil microbial activity by providing an energy source to microorganisms and enhance plant growth by providing a broad array of nutrients (Mokgolo et al 2019;Wu et al 2020).…”

Purpose The low availability of phosphorus (P) severely limits crop production in sub-Saharan Africa. We evaluated phosphate rock-enriched composts on soil properties and sorghum growth for use as environment-friendly fertilizers. Methods Treatments were sorghum straw, compost (Comp), Phosphate Rock (BPR), BPR-enriched compost (P-Comp), BPR-soil-enriched compost (P-Comp-Soil), nitrogen-phosphorus-potassium (NPK, 60-90-30), and control without phosphorus and organic material (CT). Sorgum straw and composts were applied at 1.34 tons ha-1. The amounts of nitrogen, phosphorus, and potassium in treatments, except in CT, were adjusted to 60, 90, 30 kg ha-1, with urea, BPR, and KCl, respectively. Sorghum vr. Kapelga was cultivated and soil samples were collected on days 52, 93, and 115 (harvest) for analysis. Results NPK and P-Comp-Soil provided the best sorghum yields. Soil available P was less in these treatments. P-Comp-Soil-amended soils recorded higher populations of bacteria (16S rRNA), acid phosphatase (aphA), phosphonatase (phnX), glucose dehydrogenase (gcd) and its cofactor pyrroloquinoline quinone (pqqE) genes. Phosphate-specific transporter (pstS) and arbuscular mycorrhizal fungi (AMF) abundances were generally higher in P-Comp-Soil soils, especially at the early growth stage. This active microbial activity in the P-Comp-Soil added to its initially higher available P justified a better nutrient uptake and yields comparable to NPK. Multivariate analysis also revealed the contribution of nitrogen, carbon, and exchangeable cations in sorghum growth. Conclusion This study demonstrated that direct phosphate rock application is not effective in sub-Saharan African upland cultivation. Alternative to chemical fertilizers, soils may be amended with phosphate rock-enriched composts, a niche of beneficial microbes improving soil health.
