“…The second principal component explained 18.4% of the total variation with a positive correlation to EA and clay contents while exhibiting a negative correlation with BD. The findings are consistent with reported studies in (Sadiq et al, 2021).…”

“…According to (Andrews, Karlen, & Cambardella, 2004), a suitable indicator should have a strong relationship to the particular soil function, replicable and inexpensive to analyze. Reliance on soil physicochemical properties to establish the soil health of particular ecosystems has been applied across several studies (Musa & Gisilanbe, 2017;Sadiq, Maniyunda, Anumah, & Adegoke, 2021;Worku & Bedadi, 2016) hence makes it a suitable indicator for this study. Recent reports have observed a decline in soil quality across the African region caused by a loss in biological activity, soil structural degradation and reduction in the availability of micro and macronutrients (Gachimbi, 2002).…”

Soil, water and air work interchangeably for optimum growth and productivity. Soil as a resource provides crops with essential nutrients necessary for growth and human consumption. With the insurgence of high population growth leading to pressure on lands, poor land management etc., this tendency of the soil as a nutrient pool is seen to be dwindling. It is therefore prudent to investigate and understand the dynamism of soil properties to inform proper management. Understanding topography effects and assessing soil properties on different slope positions is a first-hand step in ensuring proper soil management practices. This paper considers the assessment of physico-chemical properties of soils located on different slope gradients and land use types on the Wamaso research site in Ghana made principally of cape coast granite. In all, eighteen samples were collected from identified horizons of five distinctive subsections of the slope were delineated as follows, summit (PP1), shoulder (PP2), middle (PP3), foot slope (PP4) and toe slope (PP5) respectively. Remarkable variations were observed within PP1 to PP3 and then PP5. Pearson's correlation index revealed that the associations between most of the soil physico-chemical were not consistent across the identified slope positions. The biplot of the first two principal components together is 68.3% of the total variation and might be interpreted as change in Cation exchange capacity, sodium, sand and clay. On the first axis highlights the influence of sand and clay on soil fertility, also the relationship between pH and Na. Organic carbon derived from organic matter contributes to the availability of the basic soil cations and therefore enhances ECEC of the soils and hence the relationship obtained from the biplot. In sum, this research achieved the objective which sought to substantiate indeed the impact topography has on soil physico-chemical properties thereby serving as a reference for the classification of the soils identified.

“…The soil pH value was rated slightly acidic in the surface soil and neutral in the subsoil. Higher pH values in subsoils could be attributed to leaching of basic cations (Sadiq et al, 2021). The lower slope that recorded the highest mean pH value corroborated Seifu et al (2020), who also reported higher soil pH at lower elevations and attributed it to the accumulation of basic cations at landscape positions.…”

“…The higher available phosphorus in the surface soils than in the subsoils could be attributed to the low organic matter in the subsoils. Similarly, Sadiq et al (2021) also reported that available phosphorus decreased with depth following the organic matter distribution. The decrease in the available phosphorus with depth may be attributed to high contents of sesquioxides, which fix the phosphorus and the acidic nature of the soils (Akpan-Idiok et al, 2013).…”

“…There are complex relationships among topographic positions; land usage, and soil quality is usually site specific. Therefore, it is very important to understand the dynamics and distribution of soil properties, which are decisive factors in assessing land use and management for sustainability (Jimoh et al, 2020;Sadiq et al, 2021). For sustainable utilisation and proper management of soils, understanding their properties and their variation is very important.…”

Soil erosion and a decline in fertility are influenced by insidious topography, which results in the problem of food insecurity in developing countries. Tula is a slope terrain, thus, prone to soil degradation due to continuous cultivation, hence the need to assess soil variability and quality to guide on suitable management practices to adopt across the slope classes. Hence, this study was conceived to assess the effect of toposequence on soil properties and quality in Tula, Gombe state Nigeria. Three slope classes were selected (upper, middle and lower slope). Soil samples were collected from each slope class at depths of 0–15 cm and 15–30 cm and analysed for soil physical and chemical properties using standard procedures. The results show that the soil texture varies from loamy sandy to sandy. The bulk density ranges from 1.02 to 1.12 mg.cm−3 and were rated medium at <1.6 mg.cm−3. Soils on the lower slope were significantly (p < 0.05) higher in soil pH. The soils were generally slightly acidic to neutral. Soil organic carbon was medium in the upper and lower slopes (>10 mg.kg−1), while the middle slope was low. The exchangeable bases were rated medium to high across the slope. The soils in the upper slope were of high quality (17 = SQ1), soils in the lower slope were moderate in quality (22 = SQ2) due to low effective cation exchange capacity, and soils in the middle slope were poor in quality (26 = SQ3) due to low soil nutrients. The implication to farmers is that crop grown on upper and lower slope will grow better than those on middle slope due to variations in nutrients. The middle slope was more afflicted by denudation processes because its steep slopes favour erosion. In conclusion, our data show that soil nutrient and quality varies across slope classes and different management practices should be adopted based on slope classes for sustainable crop production. Farmers are therefore advised to add more organic manure and crop residues as well as practice terrace farming on the middle slope for sustainability.
