“…The study was carried out in South Kinangop in Nyandarua County in Kenya, which lies at 0.95° S and 36.76° E at an altitude of 2552 m above sea level. The study area has a cool and temperate climate, and has an annual mean rainfall of 1200 mm and annual mean temperature range of 10° C to 15° C. Rainfall is distributed in two seasons; the first season locally called 'long rains' occur from March to May, and the second season called 'short rains' from October to December (Jaetzold et al, 2006;Haile et al, 2023). Soil sampling was done in February 2021, and monthly mean rainfall and monthly mean temperature was 190 mm and 16° C, respectively, between December 2020 and March 2021 (Haile et al, 2023).…”

Background: Forest conversion to other land use types lead to changes in soil physico-chemical properties and a reduction in soil fertility. Although forest conversion is extensively recognized to alter soil properties, the influence on distribution of soil phosphorus (P) fractions and abundance and diversity of soil biota is not well explored. Objective: To assess the effects of converting undisturbed natural forest to plantation forest (cypress), grazed pastures and potato fields on soil phosphorus (P) fractions and abundance and diversity of arbuscular mycorrhizal fungi (AMF) in Nyandarua County, Kenya. Methodology: Transects laid out in triplicate were established in each land use type. In potato fields and grazed pastures, transects measured 50 m with three sampling points established 15 m apart along each transect, each point measuring 1 m² divided into 25 grids with each grid being 400 cm². Transect length was increased to 150 m in forest sites due to relatively larger size of the area studied and sampling points were placed at 50 m apart, each point measuring 25 m² and divided into 1² m grids. Soil and plant samples were randomly collected from sampling points and were used to determine chemical properties, soil P fractions and AMF spore examination. Data were analyzed by analysis of variance (ANOVA). Results: Soil chemical properties were significantly (p<0.001) higher in natural forest compared to potato fields, grazed pasture and cypress forest. On the contrary, readily labile and moderately labile P was higher in fields cultivated with potato (125.3 mg and 258.2 mg P kg-1, respectively) than in natural forest (51.1 mg and 95.3 mg P kg-1) and cypress forest (36.4 mg and 82.7 mg P kg-1, respectively). However, non-labile P was higher in natural forest (599.1 mg P kg-1) and lower in cypress forest (251.3 mg kg-1). Of the ten AMF genera identified, only Glomus and Acaulospora were significantly (p<0.01) affected by land use change, where they were more abundant in fields cultivated with potato than the other three land use types. Land use type did not significantly influence diversity and richness in AMF. However, AMF composition varied across the land use types. Implication: Land use change may negatively affect soil chemical properties, enhance redistribution of soil P, and change AMF community composition, and this could have long-term implications on soil fertility. Conclusion: Land use change from natural ecosystems to croplands, grazed pastures and tree plantations alter soil chemical properties, AMF composition and spore abundance, and redistribute soil P fractions by increasing labile P and reducing non-labile P fractions showing that the type of land use chosen significantly influence soil physical and chemical properties and soil biodiversity.

Soybean (Glycine max L. Merril) is among the key oil seed crops worldwide, providing several benefits from human consumption to the enhancement of soil productivity. In Uganda, legumes are cultivated on roughly 1.5 million ha, with soybean being produced on a lower production area of 150,000 ha compared to beans (925,000 ha) and groundnuts (253,000 ha). In terms of achievable yield, soybean emerges the highest at 1.2 t·ha−1 as compared to beans (0.5 t·ha−1) and groundnuts (0.7 t·ha−1). Despite the smallest production coverage area, the crop’s feasible grain yield is projected at 4.6 t·ha−1 under optimal environmental conditions. The major bottleneck to the crop’s production is the decreasing soil fertility, mainly caused by low nitrogen (N) but also phosphorus (P) levels in the soil. There is a high potential for supplying N from the atmosphere through biological N fixation (BNF), a natural process mediated by the symbiotic bacteria Bradyrhizobium japonicum, which requires optimum P levels for effective N fixation and increased yield. The current work reviews the present status of soybean production in Uganda, highlights its ecological requirements, importance, and constraints, and proposes the use of inoculation and P application to boost its production.

“…Despite the need for micronutrients being influenced by macronutrient deficiency, many farmers in Kenya neglect to apply organic inputs to their soils [ 46 , 47 ]. Prior studies in Kenya have documented the benefits of combining organic and inorganic fertilization in crop production, resulting in improved yields, enhanced nutrient use efficiency, soil fertility and increased faunal activities [ [48] , [49] , [50] , [51] ].…”
