“…In southern Brazil, studies demonstrated that the N applied during pasture phase of the ICLS, kept available to following summer crop, mainly due to the efficient nutrient cycling from pasture to corn (ASSMANN et al, 2003;SANDINI et al, 2011;SARTOR et al, 2018). On the other hand, in our study, the residual effect of the N applied during the corn phase (N-Corn plots) appeared not to be enough to maintain the high forage accumulation rate of this black oat and ryegrass mixture.…”

“…In these sense, owing to the constant soil cultivation in these agricultural systems (two or three crops by agricultural year), a hypothesis of carryover of fertilization from one crop to another was reported (ASSMANN et al, 2003). In southern Brazil, studies have confirmed a residual effect of nitrogen fertilization applied during winter pasture on subsequent corn crop in summer (SANDINI et al, 2011;SARTOR et al, 2018). Assmann et al (2003) found that the application of 300 kg N ha −1 to winter pasture resulted in no yield response in corn to further N fertilization in the summer.…”

“…According to these authors, most of nitrogen applied during pasture phase was still available to corn in summer, thus the corn N-fertilization would not be necessary due to the efficient nutrient cycling from pasture to corn. Sartor et al (2018) explained that the nitrogen fertilizer applied during the winter pasture phase may provide higher forage accumulation and consequently increase animal production, moreover nutrient cycling can improve the following crop yield in summer, especially grasses, demonstrating that the fertilization is not restrictive to one crop in the crop-pasture rotation. In this context, a new criteria for nitrogen fertilization recommendation in ICLS is suggested, with better use of N sources.…”

Nutrient cycling represents an important nutrient source in the Integrated Crop-Livestock Systems (ICLS). In general, only the crop phase of the ICLS is fertilized, however little is known about this residual effect of nitrogen fertilization from summer crop to succeeding winter pasture. This research aimed to evaluate the forage growth dynamic and botanical composition of a mixed pasture of black oat (Avena strigosa Schreb) and ryegrass (Lolium multiflorum Lam.) affected by two canopy height managements (high and low) and nitrogen fertilization applied to either the summer crop (corn) or winter pasture phase of an ICLS. The experiment was established in 2012 in southern Brazil. Black oat and ryegrass were growing during winter season and corn (Zea mays L.) during summer season, being this paper related to the 2014 pasture period. Treatments were composed by two canopy heights (25 and 10 cm) and two N-Fertilization Times (N-Pasture or N-Corn) of 200 kg of N ha-1. Canopy height was regulated by beef steers grazing through continuous stocking with a variable stocking rate. Forage mass was lower in the 10 cm canopy height on average, however this forage mass was composed by greater proportion of ryegrass leaves and lower proportion of dead material in relation to the treatment with 25 cm canopy height. The N-fertilization applied directly on pasture phase (N-Pasture) increased forage mass, tiller population density, participation of ryegrass and ryegrass leaf proportion in the forage mass. Furthermore, when pasture was fertilized with N, the forage accumulation rate increased about 69%, highlighting that the corn N-fertilization did not present significant effect on forage productivity. The residual effect of corn N-fertilization was not enough to maintain high forage accumulation. Thus, the pasture N-fertilization is fundamental to keep high-productive crop-livestock system.

“…Currently, fertilizer recommendations target to meet crop needs and to increase soil nutrient levels above critical thresholds. Conserving the nutrients is key for agroecosystem success, and the grazing animal play a crucial function to nutrient cycling and can affect positively subsequent crops yields when managed under moderate grazing intensities (Sartor et al 2018). Thus, a new approach of fertilization emerges-the system fertilization-which is based on the conceptual framework that fertilizer must be applied in the system phase that presents lower nutrient extraction and higher nutrient cycling capacity to maximize total system production (Assmann et al 2017).…”

Integrated crop-livestock systems (ICLS) can be an alternative to increase the productivity of agroecosystems by enhancing nutrient cycling via grazing animals. Despite the holistic approach that bears the designing of ICLS, fertilization practices are proceeded in a conventional crop basis, disregarding nutrient fluxes at the appropriate spatial and temporal dynamics. We argue that fertilization practices in ICLS must follow the same integrated approach. To test this, we compared a conventional crop fertilization strategy versus a system fertilization approach applied to two production systems being a conventional cropping system and ICLS. The conventional cropping system consisted of a soybean crop succeeded by a non-grazed Italian ryegrass cover crop. The ICLS model consisted of a soybean-Italian ryegrass rotation grazed by sheep. In the conventional crop fertilization strategy phosphorus and potassium were applied at soybean sowing and nitrogen at the Italian ryegrass establishment. The system fertilization consisted of the application of all nutrients during the Italian ryegrass establishment. Accordingly, treatments were fertilization strategies in a factorial framework with production systems randomly distributed in a complete block design with four replicates. Results indicated for the first time greater daily herbage accumulation rate (24%; P < 0.01) and total herbage production (18%; P < 0.05) in the system fertilization compared with conventional crop fertilization. Consequently, system fertilization allowed for greater stocking rates in the pasture phase (17%; P < 0.05). The ICLS presented greater equivalent soybean yield (P < 0.001), energy production (P < 0.01), and system productivity (P < 0.05) compared with the cropping system, regardless of fertilization strategies. Soybean yield was not affected by fertilization strategies or grazing. In conclusion, the adoption of system fertilization strategy and crop-livestock integration enhance the production without jeopardizing soybean grain yields, so that land use is optimized by a greater energy production per unit of nutrient applied.

Animal supplementation and grass-legume mixture can increase the stocking rate and crop and animal waste in the soil. Our hypothesis is that these alternatives can increase the amount of nitrogen recycled in an integrated crop-livestock system. We analyzed in an integrated croplivestock system, whether the nitrogen recycling and the soybean crops are influenced by legume and animal supplementation (1% live weight) in beef cattle production. We evaluated animal nitrogen intake, the recycled through feces and urine, and the amount of nitrogen retained in beef cattle carcass. In summer, the rate of dry matter, and nutrient release from the residual biomass after grazing and feces of animals, the export of nitrogen by soybean crops, and grain production. It was possible to increase the stocking rate in 21% through supplementation and with this there was a 33% increase in the return of nitrogen through feces and urine compared to the control. This result interfered with the export of nitrogen in grains, which was 9% higher in paddocks where there was animal supplementation. The amount of nitrogen exporting by the animals, in 90 days of grazing, did not differ between treatments, averaging 8.18 kg ha− 1 of N. Nitrogen return in a complete cycle increased by 19%, where animal and legume supplementation was used. We concluded that the supplementation and use of legumes are alternatives to increase the nitrogen recycled in integrated farming systems. Of the total N exporting, about 3 to 4% are through animals, and 96 to 97% are through soybean grains.
