“…In Belgium, the researchers found that the sample preparation method to establish N-NO 3 − concentrations did not influence the determination itself, when the samples were analysed immediately on arrival from the field, storing them at 4°C. However, it confirmed the tendencies achieved by us, that longer storage time of soil samples, even at 4°C, allows further biological oxidation of ammonium to nitrate (nitrification) (Vandendriessche et al, 2011). There is evidence that biological nitrification processes in soil take place even when soil samples are stored at −10°C (Magesan et al, 2002;Nina, Sigunga, 2012).…”

“…There is evidence that biological nitrification processes in soil take place even when soil samples are stored at −10°C (Magesan et al, 2002;Nina, Sigunga, 2012). Meanwhile, soil sample drying stops this processes in soil (Vandendriessche et al, 2011). In moist soil oxygen stimulates the activity of nitrifying bacteria resulting in an increased nitrate (NO 3 − ) content in the samples during their storage.…”

“…To prepare an average soil sample is complicated as in outdoor conditions such sample is composed of 10-15 borings and for chemical analyses only 25 g of soil is required. Thus, in preparing an average soil sample it is easier, and chemical analyses can be conducted faster to mix oven dried soil compared to field-moist soil (Vandendriessche et al, 2011;Deressa, 2014). This is particularly important since intensive biochemical transformation of nitrogen compounds takes place in soil: ammonification, nitrification, fixation in soil sorption complex, denitrification and evaporation depending on soil moisture, temperature and other factors.…”

Mineral nitrogen in soils of Lithuania's agricultural land: comparison of oven-dried and field-moist samples. Zemdirbyste-Agriculture, 105 (2): 99- AbstractMineral nitrogen (N min = N-NH 4 + + N-NO 3 − ) in oven-dried and field-moist samples was investigated in 2011-2014 in five areas of Lithuania with soils of different texture (sand, sandy loam, loam and clay) and different mineral nitrogen (N min ) content. The samples were taken in spring (from late March to early April) and autumn (late October -early November), from the 0-30, 30-60 and 60-90 cm as well as from 0-60 cm soil layers. The aim of the research was to determine the influence of different methods of soil sample preparation on the concentrations of ammonium (N-NH 4 + ) and nitrate (N-NO 3 − ) nitrogen in oven-dried and field-moist samples and to assess the suitability of the obtained results for the development of agricultural plant fertilisation plans. According to the research results, drying of soil samples at a temperature of 35°C for 12 hours resulted in significantly higher levels of N-NH 4 + compared to those of field-moist samples. The N-NO 3 − concentrations in the field-moist samples, when stored at a 4°C temperature for 3 days, increased marginally compared to the oven-dried soil samples. Weak or moderate, however, statistically significant correlations were observed between N-NH 4 + concentrations in the oven-dried and field-moist samples. In order to perform faster chemical analyses of soil N min for making agricultural plant fertilisation plans, it is necessary to carry out analyses on oven-dried soil samples, and using the linear correlation equations, to convert the results of N-NH 4 + analyses into field-moisture data.Keywords: ammonium and nitrate nitrogen, preparation of samples for analysis.

“…The amount of time that passed between in-field testing and conventional laboratory analysis is expected to have influenced the quality of comparison between the methods. Soil nitrogen concentration is highly variable-in lightly textured soils, there can be a 20.2% deviation from day 1 to day 2 for refrigerated samples (Vandendriessche et al, 2011). This means, the time between using the paper strip and the time taken for laboratories to conduct the comparison test is expected to have contributed to the variation recorded.…”

Agriculture in Sub-Saharan Africa faces abundant challenges, among others low crop yields estimated at 1.5 t ha −1 for cereals compared to a global average of 3.5 t ha −1 (FAO, 2015). This is primarily due to the sector's dependence on variable rainfall (Chauvin et al., 2012) and low application rates of mineral fertilizers, with Ghana and Kenya applying 23.8 and 28.6 kg ha −1 to arable land, respectively, compared with the global average of 137.6 kg ha −1 (World Bank, 2018).

“…Analysis of air-dried soils provides a reliable and reproducible measurement of ammonium and nitrate and appropriate for relative comparisons among wetland soils. This method is broadly used in soil fertility studies (Robertson et al, 1999;Ma et al, 2005;Vandendriessche et al, 2011). Soil organic matter content (total organic C and total N) was analyzed using an elemental analyzer (ECS 4010, COSTECH Analytical Instruments, Valencia, CA, USA).…”

Peralta, AL, et al. 2018 Wetland management strategies lead to tradeoffs in ecological structure and function. Elem Sci Anth 5: 74. DOI: https://doi.org/10.1525/elementa.253 RESEARCH ARTICLEWetland management strategies lead to tradeoffs in ecological structure and function Ariane L. Peralta * , Mario E. Muscarella † and Jeffrey W. Matthews ‡ Anthropogenic legacy effects often occur as a consequence of land use change or land management and can leave behind long-lasting changes to ecosystem structure and function. This legacy is described as a memory in the form of ecological structure or ecological interactions that remains at a location from a previous condition. We examined how forested floodplain restoration strategy, based on planting intensity, influenced wetland community structure and soil chemical and physical factors after 15 years. The site was divided into 15 strips, and strips were assigned to one of five restoration treatments: plantings of acorns, 2-year-old seedlings, 5-ft bareroot trees, balled and burlapped trees, and natural seed bank regeneration. Our community composition survey revealed that plots planted with bareroot or balled and burlapped trees developed closed tree canopies with little herbaceous understory, while acorn plantings and natural colonization plots developed into dense stands of the invasive species reed canary grass (RCG; Phalaris arundinacea). Restoration strategy influenced bacterial community composition but to a lesser degree compared to the plant community response, and riverine hydrology and restoration strategy influenced wetland soil conditions. Soil ammonium concentrations and pH were similar across all wetland restoration treatments, while total organic carbon was highest in forest and RCG-dominated plots compared to mixed patches of trees and open areas. The differences in restoration strategy and associated economic investment resulted in ecological tradeoffs. The upfront investment in larger, more mature trees (i.e., bareroot, balled and burlapped) led to floodplain forested communities, while cheaper, more passive planting strategies (i.e., seedlings, seedbank, or acorns) resulted in dense stands of invasive RCG, despite the similar floodplain hydrology across all sites. Therefore, recovery of multiple ecosystem services that encompass plant and microbial-derived functions will need to include additional strategies for the recovery of plants, microbes, environment, and functions.
