“…The highest DMP in treatments with PS denote the efficiency of these applications in increasing DMP, with similar results to mineral fertilizers, as also found in other studies [6,27,28]. The literature shows that PS has been used as organic fertilizer, mainly as a source of N in areas cultivated with pastures and annual crops [26,34,56,[66][67][68].…”

“…PS can be as efficient as urea for the supply of N to pasture soils [26], with the advantage of a slow release of N [27], resulting in significant increases in biomass production [6,10,27,28]. In addition, it can increase soil organic carbon [29][30][31][32][33] and total nitrogen [31,[34][35][36] contents, improve soil aggregation [15,17,30,37,38], minimize adverse effects of C and N emission to the atmosphere by volatilization and nitrification, and improve C and N retention by microorganisms, plant biomass, and soil aggregates [9,[39][40][41].…”

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.

“…There was an increasing linear effect (P > 0.05) of the mineral fertilizer dose on dry matter production ( Figure 2). Similar results were verified by authors [26] [27] in the dry mass production of pasture, in which they verified the linear growth according to the swine liquid manure doses.…”

The objective was to verify the possibility of supplying the nutritional requirement of Tifton 85 grass with swine liquid manure in an intensive management system. The experiment was carried out in a randomized block design, with four treatments of swine liquid manure doses: 0, 70, 140 and 210 m 3 •ha −1 , divided into seven applications and a treatment of mineral fertilization of 200 kg of nitrogen ha −1 •year −1. Samples of the collected plant material were weighed to obtain fresh mass taken for drying and then ground for bromatological determination. The dry mass production data were obtained by dry matter accumulation during the cuts and averages were made for the variables; plant height, crude protein, NDF, ADF, neutral detergent insoluble protein (NDIP) and acid detergent insoluble protein (ADIP). The data were subjected to variance analysis, performing regression for swine liquid manure doses and averages test (Dunnett test) to compare the doses with the mineral fertilization. Higher plant heights, dry mass production, crude protein content, neutral detergent insoluble protein content and lower neutral detergent fiber content in Tifton 85 grass were observed with mineral fertilization. In the variables, acid detergent fiber and acid detergent insoluble protein there was no difference (P = 0.05) between the mineral fertilization and the swine liquid manure doses. There was a linear increase (P = 0.05) of swine liquid manure doses only in dry matter production. Swine liquid manure doses up to 210 m 3 •ha −1 •year −1 do not meet the entire nutritional requirement of Tifton 85 grass, recommending the evaluation of higher swine liquid manure doses or complementation with mineral fertilization.

“…The N remaining in the soil profile at the end of the cropping season may benefit subsequent crops, which is known as the residual effect (Albuquerque et al 2017 ), but losses to soil and air should remain under certain acceptable limits. In the last harvest of 2007, the ratio between N yield of M090 vs. the one of the S146 treatment (Fig.…”

Intensive pig farming produces large amounts of slurry, which is applied to agricultural soils as fertilizer. A 7-year field study was performed to check the effect of pig slurry on soil properties and on the accumulation of some essential nutrients and heavy metals in a calcareous silty-loam soil (0–0.3 m) and in barley (Hordeum vulgare L.) plants in two cropping seasons with contrasting amounts of rainfall. Five fertilization treatments, control (no N applied), mineral fertilizer (90 kg N ha−1), and different N doses of pig slurry (146, 281, 534 kg N ha−1), were applied at sowing of a barley crop. Organic carbon, available P and K, and total P in soil increased with slurry dose. No differences were found in Co, Cr, Fe, Mn, Ni, and Pb soil concentrations. Slurries increased Cu, Mn, and Zn extractions and plant concentrations of P in straw and Zn in grain. However, the lowest slurry rate was able to maintain the highest grain yields while improving fertility. The results of this research study support the sustainability of pig slurry fertilization at appropriate rates in relation to soil chemical quality.
