“…These results suggest that the released of N by organic sources in the soil occurred mostly prior to the moment of higher N demand by corn. For this reason, it is interesting to combine the use of organic sources such as animal manure (before sowing) with the use of mineral N sources (top dressing), especially in grasses such as corn, in which split fertilization is recommended during the crop cycle (Ciancio et al 2014;Zhang et al 2016;Martínez et al 2017aMartínez et al , 2017b. The combined use of organic and mineral N sources is corroborated by the study of Guo et al (2016), who found that applying only 25% of total N recommendation in mineral form and 75% in organic form (manure) was enough to reach yields similar to treatments with 100% mineral fertilization.…”

The study aimed to evaluate the effects of long-term organic and mineral fertilization on soil solution dynamics of nitrogen (N), as well as to understand its relationship with corn plant growth, plant N uptake, and grain yield. The study was conducted in Santa Maria, State of Rio Grande do Sul, Brazil, for 12 years. The treatments consisted of pig slurry (PS); cattle slurry (CS); pig deeplitter (PL); mineral fertilizer (NPK); and no fertilization (control). We determined concentrations of dissolved inorganic N (DIN) and dissolved organic N (DON) in soil solution in situ, prior to sowing and during the growing cycle of corn. In plants, we determined the gaseous exchange, shoot N content, grain yield, and indices of recovery and efficiency of N. DIN in soil solution was the predominant N form in all treatments, ranging from 53 to 80% of total dissolved nitrogen (TDN). NPK was the only treatment that maintained high NO 3-concentration in the soil solution up to 35 days after plant emergence (DAE) and this resulted in higher grain yield. The plants fertilized with CS obtained a recovery of 80% of the N, and promoted improvements in crop growth. The results of this study showed the importance of combining the application of organic fertilizers (before sowing) with mineral sources of N (topdressing), allowing the maintenance of N availability in the soil solution during periods of demand of organic fertilizer.

“…In Brazil, the daily production of cattle manure can reach 40 thousand tons (Santos and Nogueira, 2012). Manure is typically applied to soil as a source of nutrients to crops, but it may result in soil and water contamination (Ciancio et al, 2014;Ciapparelli et al, 2016).…”

The efficiency index (EI) refers to the ratio of nutrients mineralized/made available in the soil to the total amount of nutrients added by organic fertilizer. Therefore, understanding the EI is essential for recommendation of organic fertilization. The aim of this study was to evaluate the availability through mineralization and the efficiency index of nitrogen (N), phosphorus (P), and potassium (K) in organic fertilizers produced from cattle manure. The following treatments were evaluated in an incubation experiment under controlled conditions: soil without fertilizer (control); soil + beef cattle manure vermicompost; soil + beef cattle manure/straw compost; soil + beef cattle manure; soil + dairy cattle manure; and soil + vermicompost produced under conditions of high moisture and forced air. Nitrogen and P mineralization and K availability in the soil were evaluated at 0, 7, 14, 28, 56, 112, 224, and 365 days. Nitrogen availability in the soil increased after the bioconversion of cattle manure by composting, whereas phosphorus availability increased by vermicomposting. The average efficiency indices of N, P, and K of the fertilizers produced from cattle manure were 16, 57, and 82 %, respectively. These efficiency indices are lower than the values presented by the Liming and Fertilization Manual for the states of Rio Grande do Sul (RS) and Santa Catarina (SC), Brazil.

“…The use of organic waste such as pig slurry manure (PSM), liquid cattle manure (LCM), and swine deep bedding (SDB) has increased over the years in annual crops or cultivation of perennial crops, due to the fertilizer potential of these wastes (Guardini et al 2012;Ciancio et al 2014;Lourenzi et al 2014). Usually, the dose of organic wastes to be applied to the soil is established based on the percentage of dry matter (DM), the concentration of macronutrients such as nitrogen (N), phosphorus (P), potassium (K), and the index of efficiency, which is related to the entire amount of nutrients contained in waste that can be processed from an organic to a mineral form (CQFS-RS/SC 2004).…”

Applications for long periods of organic animal waste as a source of nutrients to crops can contaminate the soil and the surface and subsurface waters. This study aimed to evaluate how the utilization of organic waste, after successive applications, affects P fractions in the soil and consequently environmental contamination. deep bedding and NPK fertilizer for eight years (urea + triple superphosphate + potassium chloride) provided accumulations of P fractions in the soil that were above the necessary for a proper nutrition to plants considering the available P fractions (AER + organic NaHCO 3 + inorganic NaHCO 3 ) in the soil. In addition, they showed that the use of swine deep bedding, followed by pig slurry, means higher levels of available P fractions in the soil. In this sense, the establishment of a dosage of organic waste to meet the nitrogen need of crops is not an environmentally appropriate parameter. It may cause P accumulation in the soil, increased absorption ability of plants and soil support, contributing to environmental contamination.
