“…Long-term application of poultry, pig, or cattle manure [21] and the application of compost [22][23][24][25] or farmyard manure [22,[24][25][26] also increases GRSP content. Higher GRSP content was also reported after the application of sewage sludge [13,27] and straw [28,29].…”

The Influence of Organic and Mineral Fertilizers on the Quality of Soil Organic Matter and Glomalin Content

et al. 2022

The influence of different fertilizers (mineral/organic) on the quantity and quality of soil organic matter was monitored in long-term stationary experiments (27 years) with silage maize monoculture production on Luvisol. The main aim of this study was to investigate the relationship between easily extractable glomalin (EEG), total glomalin (TG), and parameters commonly used for the determination of soil organic matter quality, i.e., the content of humic acids (CHA), fulvic acids (CFA), and potential wettability index (PWI). A significant correlation was found between EEG content and CSOM content, humic acid content (CHA), humic acid/fulvic acid ratio (CHA/CFA), PWI, and index of aromaticity (IAR). Furthermore, the contents of EEG and TG correlated with soil organic carbon (CSOM). Periodical application of sewage sludge and cattle slurry increased the content of glomalin in soils. From the results, it is obvious that data about glomalin content can be used to study soil organic matter quality. A more sensitive method (a method that reacts more to changes in components of soil fertility) seems to be the determination of EEG rather than TG. The factors supporting use of EEG extraction in agronomic practice are mainly the substantially shorter time of analysis than TG, CHA, and CFA determination and lower chemical consumption. Furthermore, the PWI method is even suitable for studying soil organic matter quality. On the other hand, the humus quality ratio (E4/E6) does not provide relevant information about soil organic matter quality.

“…In addition, the lowest PS rates presented higher macroaggregate mass, which usually contain more organic carbon than microaggregates [68,69], compensating the lower addition of C by the PS. Moreover, the SOM decomposition is higher and the C:N is lower in microaggregates [56,70].…”

“…Soil aggregation is highly affected by the root system quality, mainly of grasses, whose fasciculate root system promote aggregation by the release of exudates and entanglements within soil particles, increasing macroaggregate formation and stability [54]. In addition, PS applications stimulate soil microbial activity and mycelium and glomalin production by mycorrhizal arbuscular fungi, which contribute to soil aggregation [55,56].…”

“…They also found several benefits for the use of animal manure compared to mineral fertilizer, including the reduction in runoff and soil erosion; increases in water infiltration into the soil, possibly leading to a higher tolerance to drought; partial offset of higher soil P levels resulting from manure application; and decreases in P loss to local surface water. According Řezáčová et al [56], the use of pig slurry as organic fertilizer improves soil aggregation through increases in abundance of eubacteria and products from arbuscular mycorrhizal fungi.…”

Aggregation Index and Carbon and Nitrogen Contents in Aggregates of Pasture Soils under Successive Applications of Pig Slurry in Southern Brazil

et al. 2022

View full text Add to dashboard Cite

Pig slurry (PS) applications affect soil aggregation and carbon and nitrogen contents in aggregates. The objective of this study was to evaluate changes caused by successive applications of PS and mineral fertilizer on soil aggregation and carbon (C) and nitrogen (N) contents in aggregates of a clayey Typic Hapludox cultivated with Cynodon dactylon cv. Tifton-85 in southern Brazil. The treatments consisted of six annual applications of PS (100, 200, 300, and 400 kg N ha−1) and urea (200 kg N ha−1), and a control with no fertilizer application. Soil samples were collected in March 2019 and evaluated for aggregate stability, through the geometric mean diameter of aggregates (GMD), and GMD sensitivity index (SIGMD), and mass of macro-, meso-, and microaggregates. Total organic carbon and nitrogen contents were determined in macroaggregates and microaggregates. Applications of PS to pasture soils increase dry matter production of Tifton-85 and can increase soil aggregation by increasing the mass of macroaggregates. The highest PS rates decreased aggregate stability, resulting in lower macroaggregate mass, GMD, and SIGMD, and higher microaggregate mass. PS applications to pasture soils can increase C and N contents in macro and microaggregates, and improve soil aggregation when using the rates of 100 or 200 kg N ha−1, mainly in subsurface layers.

“…Disruption of mycorrhizal communities is primarily due to the type of management applied to the grassland, especially the type of fertilization [37][38][39]. Organic inputs are considered to increase the mycorrhizal process of plant species [40][41][42] and mineral inputs act differently or promote or slow down the process [43,44]. Nitrogen fertilization enhances the symbiotic process only if the phosphorus is deficient in the soil, whereas if the phosphorus is in the right amount in the soil the nitrogen fertilization leads to a destabilization of the symbiosis [45].…”

Long-Term Fertilization Alters Mycorrhizal Colonization Strategy in the Roots of Agrostis capillaris

et al. 2022

Long-term fertilization targets mycorrhizal fungi adapted to symbiotic exchange of nutrients, thus restricting their colonization potential and re-orienting the colonization strategies. The MycoPatt tool has a high applicability in quantifying the symbiotic process with the identification of mycorrhizal indices and projection of mycorrhizal patterns. Organic treatments increase the symbiotic process, visible in values of colonization frequency and intensity, with about 6% more than the native status of colonization. At the opposite pole, organic-mineral treatments decrease the colonization parameters by up to half of the organic treatment. All of the colonization parameters show significant correlations, except for the arbuscules/vesicle ratio (0.03). All the applied treatments, except for the organic one, record multiple root segments with a colonization degree lower than 10%. The application of treatments changes the strategy of native colonization from a transfer (40%) and storage (37%) to a predominant storage (50%) for organic treatment, and are mainly proliferative between 38–50% in mixed and mineral treatments. The high amount of mineral components increases also the presence of resistance conditions strategies. The use of mycorrhizal pattern maps, with the inclusion of colonization strategies, presents an important direction in understanding the evolution of mutual relations, and to explore in-depth the efficiency of the whole symbiotic process.
