“…The organic fraction of the nutrient corresponds to 95% of the total N present in the soil (Müller et al, 2011). The SOM levels in this study may be classified as medium and high (Silva et al, 2016), which would allow them to stabilize the N content in the soil (Mafra et al, 2014;Grohskopf et al, 2015).…”

The objective of this work was to evaluate the effects of organomineral and mineral fertilizers, in their solid and fluid forms, on soils with variable charges with high fertility built up from nitrogen, phosphorus, and potassium contents in the soil and plant, as well as on corn (Zea mays) and black oat (Avena strigosa) yield. The treatments consisted of one control and four fertilizers - two organomineral and two mineral - in solid (SO, solid organomineral; and SM, solid mineral) and fluid (FO, fluid organomineral; and FM, fluid mineral) forms applied in Rhodic Kandiudox and Distrochrept soils with no-tillage. The use of organomineral or mineral fertilizers in fluid and solid forms increases total N content in the soil, maintains exchangeable K content in both soils, and may enhance available P content to the depth of 0.6 m in Distrochrept. These factors allowed significantly increasing corn yield, regardless of the fertilizer, and establishing greater residual effect for fluid organomineral fertilizer in the winter black oat yield, even in soils with high fertility.

“…Furthermore, research is needed on reuse of the nutrients available in organic waste (Grohskopf et al, 2015) and the use of highly productive conservation systems, such as integrated crop-livestock production systems (ICL), which place particular importance on soil fertility (Tormena et al, 2012).…”

Organic fertilizers derived from poultry litter and pig slurry are alternatives to mineral fertilizers in increasing soil nutrient availability. The aim of this study was to evaluate soil response, through characterization of organic C and available N, P, and K contents, and corn yield response to increasing amounts of poultry litter, pig slurry, and mineral fertilizers in an integrated crop-livestock production system (ICL) from 2011 to 2013. The experimental design consisted of randomized blocks in a 4 × 3 + 1 factorial arrangement with four replicates. The treatments consisted of four types of fertilizer, two organic (poultry litter and pig slurry) and two mineral, balanced with the same amounts of N, P and K as the organic fertilizers, one of which corresponded to the levels in the pig slurry (M1) and the other to the levels in the poultry litter (M2) in combination with three .increasing application rates of N (100, 200, and 300 kg ha -1 N) and control without fertilizer. For two years after implementing the ICL system, the application of the different rates of N using organic (pig slurry and poultry litter) or mineral (M1 and M2) fertilizers increased corn yields and K and P availability in the soil; these results were accompanied by small changes in organic C and total N content. There are similar efficiencies between the treatments pairs (pig slurry/M1 and poultry litter/M2).

“…The total nitrogen at 0.30 m depth presented a quadratic behavior with maximum concentrations of 1.85 g kg -1 in the ALT4 treatment submitted to 600 kg ha -1 of N ( Figure 4A) and quadratic ( Figure 4B), with a maximum concentration of 1.06 g kg -1 in the AAT3 treatment submitted to the dose of 450 kg ha -1 of N. Grohskopf et al (2015) found total nitrogen concentrations at 0.10 m depth of 2.70 g kg -1 when received the 200 m 3 ha -1 of swine wastewater (SW).…”

ABSTRACT:The aim of this study was to evaluate the soil chemical properties submitted to fertigation with slaughterhouse (SW) and dairies (DW) wastewater. The experiment was conducted in the Environmental Engineering Center and Sanitary of UFLA/MG in PVC columns filled with Dark Red Latosol (Oxisol) and randomly distributed. The treatments applied with nitrogen based load (300 kg ha years -1 of N) consisted of four doses of SW and DW (100, 200, 300 and 400% of the recommendation) and AQT0 control at random. The soil was collected at a depth of 0.30 m and, subsequently, characterized in terms of physical, chemical and physicochemical. The application of treatment of the largest irrigation of DW provided, after 120 days of monitoring, N concentration of 1.85 g kg -1 . However, the treatment with AQT0 obtained N concentration of 0.81 g kg -1 , in the soil. We observed that the largest irrigation of SW provided increases of 2.62 and 5.49 g kg -1 , respectively, in the P and K concentrations of the soil. There was quadratic increase in the N concentration in the 0.30 m soil depth of the columns with the increase in the applied irrigations of SW and DW, being obtained maximum values of 1.85 and 1.02 g kg -1 that were obtained in the relative irrigation of the application dose of 600 kg ha -1 of N.
