“…In the clayey Oxisol, liming was carried out with 2.5 and 1.9 Mg ha −1 of dolomitic limestone, in May 2007 and Aug 2013, respectively. Mineral fertilizers without taking into consideration the quantity of nutrients applied by manure is a common practice among farmers in southern Brazil and the common amount of DLM applied by farmers is 60 m 3 ha −1 year −1 split into two crop seasons (Favaretto et al, 2022). Thus, our experiment was designed to simulate this condition.…”

“…The mean P content in the grains was obtained from data spanning several crop seasons, and was very similar to what can be found in the literature (Nepar, 2019), presenting means of 4.3 g kg −1 for soybean, 2.9 g kg −1 for maize, and 3.2 g kg −1 for wheat. Crop grain yield data are presented in Barth et al (2020, 2021) for sandy and clayey Oxisols, respectively. P lost by runoff as total P was estimated using the data of soluble P losses by surface runoff during the entire period (2005–2015) (Favaretto et al, 2022) and the available data of the proportions between soluble P and particulate P lost from the first 2 years of the experimental period. The proportions were: 51% of soluble P and 49% of particulate P in the sandy Oxisol, independent of the DLM application (Silveira, 2009).…”

“…The benefits of manure application in agricultural systems to soil quality and crop yield are well-known (Barth et al, 2020(Barth et al, , 2021Bhattacharyya et al, 2010;Mamia et al, 2018). However, a common practice among farmers in the implementation of mineral fertilizer is the failure to take into consideration the quantity of nutrients applied in the manure (Favaretto et al, 2022;Shigaki et al, 2006). This management approach promotes high soil P accumulation and progressive saturation of the adsorption sites, thereby increasing P availability over the years.…”

The benefits of manure as a source of nutrients for plants and to improve soil quality are well-known. Monitoring of manure application is needed if environmental issues are to be prevented. In particular, the availability and accumulation of phosphorus (P) has to be subject to rigorous monitoring. This study aims to both evaluate the efficacy of the resin method in extracting inorganic labile P in soils under the long-term application of dairy liquid manure (DLM), and verify the influence of DLM on the recovery of applied P and soil legacy P. To realize our objectives, two long-term field experiments were established under a no-tillage system with annual DLM application on sandy clay loam (sandy Oxisol) and clayey (clayey Oxisol) soils. Treatment consisted of DLM applications (0, 60, 120, 180 m 3 ha −1 year −1 ), independent of mineral fertilizer. Soil samples were taken from the 0-5, 5-10 and 10-15 cm layers after 10 years from the beginning of the trial. A single extraction with resin underestimated inorganic labile P; however, successive extractions were able to take up 43% and 26% of the total P in sandy and clayey Oxisols, respectively, whereas in a single extraction the take-up was 17% and 8% from the same soils, respectively. The resin method was more effective in extracting P from the sandy Oxisol. Thus, when interpreting soil P contents for fertilizer planning, the soil texture should be taken into account. DLM application decreased P recovered from applied P, ranging from 54% to 83% (sandy), and 43% to 67% (clayey), and substantially increased soil legacy P.

“…These aspects remain vastly unknown, particularly in tropical and subtropical regions such as South America, despite their global importance in agricultural production and high abundance of animal husbandry. Moreover, under tropical/subtropical conditions of heavy and sudden rainfall events, water‐induced erosion processes can be intense, and thus inappropriate soil management can quickly lead to severe and rather irreversible degradation (Ebling et al., 2022; Favaretto et al., 2022; Reichert et al., 2019).…”

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.
