“…Similar results were reported [10,34], indicating significantly higher extractable P in the surface layer under CA as compared to CT. The extractable P varied significantly (p > 0.05) among the fertilized and unfertilized treatments, which agrees with other studies [10,28] where a significant N fertilization effect on extractable P was observed. This was expected because of P fertilization.…”

“…The pH varied insignificantly among the fertilization treatments and cropping patterns alone. A similar result was reported [28], where fertilization of P had no significant changes in pH. After two years, for the cropping pattern, increased pH of 2.6% was observed under sole cowpea (5.78) as compared to sole pigeon pea (5).…”

“…Fertilization and cropping pattern factors alone had no significant effects on OC. It is noteworthy that no significant N and P fertilization effects on OC were observed [28]. Although no significant effects were recorded for cropping pattern, the highest OC was noted in sole pigeon pea and maizecowpea intercropping (0.64%) and the lowest under sole groundnut and maize-pigeon pea intercropping (0.60%).…”

Short-Term Effects of Tillage Systems, Fertilization, and Cropping Patterns on Soil Chemical Properties and Maize Yields in a Loamy Sand Soil in Southern Mozambique

Sub-Saharan Africa (SSA) agriculture is characterized by dependence on erratic rainfall, inadequate conservation practices, and a decline in soil fertility resulting in low crop productivity. Therefore, conservation agriculture (CA) has been proposed as an alternative to improve soil fertility and productivity. Hence the aim was to investigate the effects of tillage systems, fertilization, and cropping patterns on selected soil chemical properties (pH, organic carbon, total nitrogen, extractable phosphorus, exchangeable cations, and cation exchange capacity) and identify which cropping pattern maximizes stover and grain maize–legume productivity and land use. A two-year (2016/17–2017/18) field experiment in a loamy sand soil was conducted at Nhacoongo Research Station, southern Mozambique. Two tillage systems (conservation (CA) and conventional tillage (CT)), two fertilization treatments (fertilized and unfertilized), and seven cropping patterns (four sole crops and three maize–legume intercrops) were evaluated in a randomized complete block design with split–split plot arrangement and replicated four times. CA practices resulted in significantly higher soil chemical properties and increased stover and grain yields as compared to CT practices, but fertilization demonstrated insignificant effects on soil chemical properties and significant influences on stover and grain yield of maize and legumes. Cropping patterns induced no significant effect on soil chemical properties and either stover or grain yield. Estimated indices like land equivalent ratio (1.18–2.67) and competitive ratio index (0.01–1.72) confirmed the advantage of intercropping against sole cropping. This is largely supported by the estimated values of aggressivity and relative crowding coefficient. Smallholder farmers can therefore benefit by adopting CA.

“…The effective cation exchange capacity of the soils was rated high across the toposequence. The high value of ECEC suggests a dominance of 2:1 clay minerals over sesquioxides and kaolinite clay minerals (Chidowe et al, 2014) in the soils. The decrease in ECEC with soil depth could be attributed to nutrient uptake by plants and the decrease in OC with soil depth.…”

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.
