The influence of the short storage periods at different temperatures on the concentrations of ex-tractable soil cations (Ca2+, Mg2+, Na+ and K +) and anions (Cl−,4SOand4PO) has been investi-gated in nine soil samples from Nile river terraces at River Nile State, North of Sudan (17.82289 to 17.82389N and 33.99974 to 34.02127E). Each soil extract is divided into three treatments: i) con-trol (immediately analyzed); ii) storage for 10 days and; iii) storage for 30 days. Each treatment is replicated three times: i) storage at 10˚C; ii) storage at ambient laboratory temperature (25˚C) and; iii) storage at 45˚C in incubator. Statistical analysis of results reveals that significant difference are found at level (P < 0.05) for K +, Mg2+, Ca2+, Cl−,SO and PO (0.043, 0.002, 0.001, 0.021, 0.004 and 0.001) respectively at 25˚C and 45˚C and storage periods of 10 and 30 days. In contrast, signif-icant difference is also found at level (P < 0.001) for soluble calcium, magnesium and sulphate. In addition, results also reveal that SO concentrations are significantly decreased when the sto-rage period exceeds 10 days and temperature more than 25˚C. Depending upon our study results; we conclude that, all extractable inorganic nutrients are clearly affected by storage periods at various temperatures, exception of Na+. Most cations and anions are increased significantly with increased of storage period and temperatures. We therefore highly recommend that the extracta-ble inorganic soil nutrients should be rapidly analyzed in order to obtain accurate results; other-wise, the time between extraction and analysis should be carefully recorded which may help con-siderably interpreting data from various studies

The value of the measured exchangeable sodium ranged from 0.12 to 1.22 meq/100g of soil, with a mean value of 0.44 meq/100g of soil indicating medium sodium content of the soil. Total nitrogen ranging from 0.11 to 0.37 percent which decreases from top to sub soil. In conclusion soil and agronomic management are correlated with the well being of soil. Therefore, it is recommended that integrated nutrient management activities should be adopted in the study area for optimum and sustainable production of major crops.
Some chemical parameters of soil quality in the Šumadija region
2012
The research presented in this paper was conducted on agricultural farms in the Šumadija region. The study area is covered by different types of potentially fertile and low-fertility soils used for intensive field crop production. Basic soil fertility parameters (pH, humus, total nitrogen, available P and K) were evaluated. Most soils (about 70%) were found to be of poor quality (low pH levels, low contents of humus and readily available phosphorus). The solution to the soil quality deterioration problem occurring in the Šumadija region, primarily with respect to the degradation of soil chemical properties (high acidity and low levels of readily available phosphorus and humus), necessitates not only appropriate fertilization but also the use of adequate soil conditioners (lime and organic materials).

The study focused on assessing the farmer's knowledge on utilization of chemical fertilizers as soil fertility enhancement option in Ruhumuro sub-county, Bushenyi district. It was limited to; establishing the local farmers'knowledge on the use of chemical fertilizers, investigating the factors that influence farmers' decisions to utilize chemical fertilizers and establishing the benefits that local farmers achieve from utilizing chemical fertilizers. The study employed a cross-sectional research design and primary data was collected from 200 respondents. the data was analyzed using SPSS version 22.0. The study concluded that farmers had local knowledge on use of chemical fertilizers where they revealed that, fertilizer use is influenced by on agroclimatic conditions and farm characteristics at (p=.027), profitability is the principal incentive to adopt fertilizer use at (p=.021), fertilizer use ensure high productivity and yields at (p=.003). The decisions on fertilizer use has mainly considered credit access and price at (p=.026) Fertilizer use alter the soil properties at p= (.029). Fertilizer applied to farmers' crops do not provide optimal economic returns to farmers as (p=.312) as non-significant. The study also concluded that there were factors that influence the farmers' decisions to utilize chemical fertilizers. Such as; ownership of land (p=.022), labour avialability (p=.024), Cost of the fertilizers (p=.004) and un-availability of credit services/financial institutions offering services (p=.028). Non-significant factors included; farming experience and level of education (p=.427, p=.369). The study concluded that there were benefits that local farmers achieve from utilizing chemical fertilizers. Such as; Restoration of soil fertility (x 2 = 3.002, p=0.021), Sustainable food production (x 2 = 2.441, p=0.001), Income security (x 2 = 0.871, p= 0.010), Improvement of crop yields (x 2 = 3.123, p=0.023) and Contribute to greenhouse effect (x 2 = 4.211, p=0.141) which was not significant. The study recommends that, there is a need for policymakers and agricultural stakeholders to consider the social, economic, and environmental implications of the widespread use of chemical fertilizers. Constant extension training services on chemical fertilizer use should be done to help farmers use the recommended dosage of fertilizers to avoid environmental degradation due to lack of adequate knowledge on fertilizer utilization. Government should undertake legal reforms to recognize and protect the rights of vulnerable groups to own and use land. They should also put in place mechanisms to ensure that the law is enforced.
