“…Moreover, applying liquid pig manure may also favour clay dispersion in soil because of an increase in sodium content and changes in the soil surface electrical potential by increasing negative charges on the particle surface (Barbosa et al, 2015). Results from Loss et al (2021), conducted in the same experiment evaluated here, indicated animal manure application (11 years) reduced the degree of flocculation and soil aggregation in depth.…”

The processes involved in deformation, internal strength and stability of soils with long‐term application of fertilizers (organic and inorganic sources) remain poorly investigated and hence understood, particularly in agricultural systems under subtropical climatic conditions. We investigated how long‐term fertilizer management with organic and inorganic amendments in no‐till crops affects the microstructural stability of a sandy Alfisol under oscillatory shear. The study was conducted in southern Brazil on a 17‐year completely randomized block experiment with five fertilizer treatments: pig slurry (PS), cattle slurry (CS), pig deep litter (PDL), mineral fertilizer (MF) and control, i.e. unfertilized (CL). Soil samples were collected from two layers (0–5 and 5–15 cm) for physical and chemical analyses and evaluation of soil rheological properties under oscillatory shear at two matric potentials (0 and −10 kPa). Organic matter accumulation in soil provided by the PDL and CS fertilizers resulted in higher soil stability and elasticity under oscillatory shear, especially in the 0–5 cm layer. Conversely, MF and PS enhanced the soil susceptibility towards deformation under transient stresses, mainly in the 0–5 cm layer under saturated conditions. The PDL significantly increased soil shear resistance under low‐shear strain conditions. Significant differences ceased under high‐shear strain conditions, though PS and MF yielded at significantly lower strains. Hence, under subtropical conditions, long‐term application of organic fertilizers with fibrous components promoted soil microstructure strengthening, reducing soil susceptibility to erosive processes and compaction.

“…Similarly, Loss et al [16] evaluated a sandy loam soil subjected to 11 years of application of animal manure, including PS, and found lower meso and microaggregate mass, and higher macroaggregates contents and GMD values in the soil surface layer when compared to mineral fertilizer (N-P-K) and control treatments. Bertagnoli et al [34] evaluated the effect of different PS rates on soil aggregation and found that soils that received the lowest PS rates (67% to 133%) improved the soil aggregation by reducing aggregates <0.25 mm up to 0.20 cm depth.…”

“…Wastes from pig production are usually managed in liquid form, called pig slurry (PS) or liquid swine manure, which are stored in anaerobic ponds and mainly used as soil fertilizer for agricultural crops, including pastures [5][6][7][8][9][10] due to the high organic matter and macro and micronutrient contents (N, P, K, Ca, Mg, Mg, Fe, Zn, Cu, and B); however, the concentration of these nutrients presents high variation [11]. PS is an alternative to commercial fertilizers to increase biomass production and quality, and reduce environmental impacts and production costs [12,13] with similar results [14][15][16].…”

“…Changes in soil chemical [24,25], physical [16,26,27], and biological [28][29][30] attributes have been found with application of PS, with positive effects on soil quality, and crop yields [10,31,32]. These benefits are mainly due to increases in organic matter contents, which favor soil aggregation and availability of nutrients to plants.…”

“…The authors in [37] evaluated PS applications to supply N for eight years and found increases in TOC contents up to 30 cm depth. In addition, Loss et al [16] evaluated the use of animal manure for 11 years under a no-tillage system and found that applications of PS increase soil TOC and TN contents and the GMD, but reduce mesoaggregates (2.0 > Ø ≥ 0.25 mm) and microaggregates (Ø < 0.25 mm) in the soil surface layer when compared to the NPK and control treatments, and that animal manure promoted the dispersion of clays in the 5-10 and 10-20 cm layers, resulting in lower soil aggregation in depth.…”

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

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.

Changes in Dry Matter and Carbon, Nitrogen, and Sulfur Stocks after Applications of Increasing Doses of Pig Slurry to Soils with Tifton-85 for Six Years in Southern Brazil

et al. 2022

Pig slurry (PS) has been used as soil fertilizer due to its nutrient and organic matter contents, which may improve soil nitrogen, carbon, and sulfur stocks. The objective of this work was to evaluate the best PS dose that favors the increase in dry matter production and carbon (C), nitrogen (N), and sulfur (S) contents and stocks after applications of PS to soils with Tifton-85 for six years. The experiment was conducted in a randomized block design with four replications, in a hay-producing area under a clayey Typic Hapludox in southern Brazil. The treatments consisted of annual applications of organic and mineral fertilizers at rates based on their N contents, using PS (100, 200, 300, and 400 kg ha−1) and urea (200 kg ha−1), and a control without N application. Samples of the soil in 0–5, 5–10, and 10–30 cm layers were collected in March 2019 and evaluated for soil bulk density and N, C, and S contents and stocks. The Tifton-85 dry matter production was evaluated using samples from three cuts carried out between 2012/2013 and 2017/2018 agricultural years. The applications of increasing doses of PS in Tifton-85 pastures over six years increase linearly the dry matter and soil organic C, N, and S stocks in the 0–30 cm layer. The PS rate equivalent to 100 or 200 kg ha−1 of N is recommended for increasing soil C, N, and S stocks, since it resulted in C, N, and S stocks equal to or higher than the control and mineral (urea) treatments.
