“…The ideal K: Mg ratio is 0.2 -0.3 (Udo et al, 2009). Considering the mean values recorded in the studied land use types, the soils of the land use types are of low fertility status .These findings are in agreement with Mbah (2006), Onweremadu (2007), and Onwudike et al (2016) who concluded that Southeastern Nigeria soils are low in fertility level. This poor fertility status is due to high rainfall in the area which increases soil erosion and leaching of plant nutrient elements.…”

The study evaluated the fertility status of some land use types in Orlu area of Imo State using elemental ratio. Soil samples were collected from three land use types namely; plantain plantation, oil palm plantation and cassava. A total of 18 samples were collected. Six soil samples were randomly collected from each land use at depths of 0-15 cm and 15-30 cm. Routine analyses were conducted and Ca/Mg and K/Mg were used to determine the fertility status of the soils. The result of physical properties indicated that mean sand content of the soils ranged from 820.1-910.1 g/kg. The mean silt content of the soils ranged from 13.3-56.7 g/kg while the clay content ranged from 76.5-136.5 mg/kg. Bulk density was highest under oil palm (1.43 g/cm 3) and lowest under cassava (1.10 g/cm 3). The results of the chemical properties showed that mean pH varied from 5.0-5.7. Soil organic carbon was highest under plantain (16.9 g/kg) and lowest under oil palm (9.3 g/kg). Ca/Mg ratio was highest under plantain (1.78) and lowest under cassava (1.20). The K/Mg was highest under oil palm (0.14) and lowest under plantain (0.02). Ca/Mg ratio of the soils indicates possible Ca deficiency and phosphorus inhibition. The K/Mg ratio of the soils shows non inhibition of the uptake of magnesium Ca/Mg ratio varied highly under plantain and cassava but had medium variation under palm oil. There was significant negative relationship between K/Mg and Mg, ECEC, Ca, base saturation (BS) and available phosphorus (-0.85,-0.85,-0.86,-0.77, and-0.47) respectively.

“…Soil conservation practices involve fertility management, which involves using techniques such as mulching, tree planting, multi-purpose tree hedge planting, contouring, fallow vegetative system, minimal tillage, double crop, and the settlement of crops, minerals, and fertilizers, among others. The literature by Onwudike et al (2016) and Daudu et al (2016) highlights several benefits of these conservation practices, including improved soil fertility, improved soil structure, labor savings, soil biodiversity, soil compaction, increased soil productivity, increased agricultural income, food safety and environmental sustainability. For instance, it has been noted that yields of crops are higher on farms with conservation practices than on farms without conservation practices, even in the same ecological zone (Ibewiro et al, 2000;Salako and Tian, 2003;James and Ngala, 2015).…”

Background. As part of efforts to reduce soil degradation and improve agricultural yield, farmers in the study area learned about various soil conservation practices through agricultural organizations. Objective. This study, therefore, investigated the impact of agricultural organizations on the adoption of soil conservation practices. Methodology. Through a multi-stage sampling procedure, the data collected were analyzed with the aid of descriptive statistics and a double hurdle regression model. Results. The descriptive results revealed that three conservation practices were majorly adopted in the study area, namely, cover crop (25 adopters), vegetative fallow (63 adopters) and mulch (83 adopters). The result further revealed significant differences in some socioeconomic characteristics between the categories of adopters in the study area, such as the age of the farmers, off-farm income, farming experience and the household size. However, the study concluded that the majority of the smallholder farmers were male, small scale and at their productive age. According to the first hurdle, the factors responsible for the adoption of the three soil conservation practices were; off-farm income, extension contact, farm size, years of education and membership in the agricultural organization. In the same vein, the factors that contributed to the intensity of soil conservation practices were membership of the agricultural organization, farm size, location of a valley on the farm land and household size. Implications. The paper adds evidence for a better understanding of the nexus between the agricultural organisation and the adoption of soil conservation practices. Conclusion. Based on these findings, the study recommends encouraging the training and strengthening of agricultural organizations for better adoption of soil conservation practices. In addition, effective strategies, programs and institutional structures that improve farmers' education, the frequency of extension contacts and off-farm income should be established.

“…In an attempt to maintain optimum crop productivity, farmers are encouraged to adopt different production technologies that would conserve the soil. In relation to this, Onwudike et al (2016) suggested adoption of many strategies aimed at improving soil productivity and crop yield. However, there is no known research that assesses the cropping practices that affect soil fertility especially in the study area (Daudu et al, 2016).…”
