“…The nitrogen fertilization of winter pasture in doses equal to or greater than 150 kg N ha -1 ensures high [38] productivity of corn crops in the absence of N application. Alves et al (2022) [39] analysed potassium and phosphate fertilization strategies in crop-livestock integration on the grain crop and found no difference in soybean productivity. They found a greater efficiency of K use, leading to a more efficient balance of available K for the soil.…”

This study aimed to evaluate levels of potassium and nitrogen fertilizer inversion in the black oat crop on corn crop yields. The experimental design was a randomized block design with subdivided plots with three repetitions. The treatments were four nitrogen fertilization strategies, four potassium fertilization strategies, and two oat crop managements (forage and cover crop). The strategies involved winter (oats) and summer (corn) application, respectively, with the following combinations of nitrogen (200-0; 150-50; 50-150; 0-200 kg N ha-1) and potassium (80-0; 60-20; 20-60; 0-80 kg K ha-1). We evaluated the morphological aspects, grain productivity, chlorophyll contents, and light interception of oats for forage production and ground cover, and for corn the yield components and productivity. Oats managed as forage showed higher forage mass production but lower values of residual biomass, canopy height, extended tiller length, lodging index, radiation interception, and oat chlorophyll A and total. Light interception in the oat crop was higher when nitrogen was applied in the pasture. For the corn crop, nitrogen applied partially on black oat and the remaining on corn row crop increases stalk diameter. Fertilization strategies showed no significant effect on both crops in the system, indicating that it is possible to reverse or apply the entire amount of N and K predicted for the two crops in winter.

“…P and K soybean requirements applied on preceding Italian ryegrass did not affect the succeeding soybean yield and increased herbage production [114]. Fertilizers applied during the pasture phase are kept in the system by the decoupling-recoupling processes and then easily obtained by soybean in succession [115].…”

“…An increase in acid phosphatase activity was reported to be correlated with an increasing soybean yield, resulting from system fertilization and the livestock zoogeochemical effect [116]. When all nutrients (N, P, and K) are applied during the pasture phase, N increases the P and K demand [115], contributing to increasing the herbage accumulation rate and total herbage production, which in turn increase the stocking rate [114]. An increase in the stocking rate may not affect the live weight gain per animal if sound sward management targets are maintained [115], but it increases animal production per unit area and contributes to increased dung and urine deposition, resulting in a heavy cycling and a great source of available nutrients, which in turn may increase soil microbial biomass [110].…”

“…Well-established ICLSs-i.e., with use of the no-till system, the presence of grazing animals in well-managed pastures in soils with high nutrient levels, and soil acidity neutralization-make it possible to achieve a well-functioning system fertilization strategy [114,121], improving land use sustainability and productivity, without increasing agriculture expansion and/or deforestation and with less dependence on external inputs. Diversification (e.g., with leguminous species in pastures), use of organic fertilizers, and new standard fertilization needs to be developed to improve the efficiency of and benefits from ICLSs.…”

Domestic Herbivores, the Crucial Trophic Level for Sustainable Agriculture: Avenues for Reconnecting Livestock to Cropping Systems

Domestic herbivores have been closely associated with the historical evolution and development of agriculture systems worldwide as a complementary system for providing milk, meat, wool, leather, and animal power. However, their major role was to enhance and maintain agricultural soil fertility through the recycling of nutrients. In turn, cereal production increased, enabling to feed a progressively increasing human population living in expanding urban areas. Further, digestion of organic matter through the rumen microbiome can also be viewed as enhancing the soil microbiome activity. In particular, when animal droppings are deposited directly in grazing areas or applied to fields as manure, the mineralization–immobilization turnover determines the availability of nitrogen, phosphorus, potassium, and other nutrients in the plant rhizosphere. Recently, this close coupling between livestock production and cereal cropping systems has been disrupted as a consequence of the tremendous use of industrial mineral fertilizers. The intensification of production within these separate and disconnected systems has resulted in huge emissions of nitrogen (N) to the environment and a dramatic deterioration in the quality of soil, air, and ground- and surface water. Consequently, to reduce drastically the dependency of modern and intensified agriculture on the massive use of N and phosphorus (P) fertilizers, we argue that a close reconnection at the local scale, of herbivore livestock production systems with cereal-based cropping systems, would help farmers to maintain and recover the fertility of their soils. This would result in more diverse agricultural landscapes including, besides cereals, grasslands as well as forage and grain crops with a higher proportion of legume species. We developed two examples showing such a beneficial reconnection through (i) an agro-ecological scenario with profound agricultural structural changes on a European scale, and (ii) typical Brazilian integrated crop–livestock systems (ICLS). On the whole, despite domestic herbivores emit methane (CH4), an important greenhouse gas, they participate to nutrient recycling, which can be viewed as a solution to maintaining long-term soil fertility in agro-ecosystems; at a moderate stocking density, ecosystem services provided by ruminants would be greater than the adverse effect of greenhouse gas (GHG).

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.
