“…(2014) and Assmann et al. (2017) in C 3 grasses (no grazing wheat and pasture residue from black oat + Italian ryegrass managed at 20 cm), probably because of lower initial P concentration (e.g., 2.6 g kg −1 ; Assmann et al., 2017) and slower P release than that found in the present study.…”

“…These results were attributed to K not being found in plant structural components (Hawkesford et al., 2012). Thus, as K is readily available from surface residues, played a minor role in organic compounds, and K release has little dependence on microbial processes (Assmann et al., 2017), its cycle tended to be shorter and faster. Therefore, to speed up K release from residues, the following crop should be planted immediately after management of the cover crop to develop a root system capable of K absorption released from residue decomposition (Assmann et al., 2014).…”

“…For this reason, Assmann et al. (2017) recommend that most of the fertilizer should be applied prior to the grazing cycle (i.e., the pasture) and a small amount should be added for soybean cropping, resulting in higher pasture and meat yields with the same amount of nutrient applied over the entire cycle.…”

“…Therefore, we want to assess the effect of including trees in ICLS on a variety of agricultural sustainability issues, one of which is nutrient cycling. Although pasture and cash‐crop residues are rich in nutrients and could serve as biological sources of fertility (Assmann et al., 2015; Assmann et al., 2017; Carvalho et al., 2010; Cavalli, Lange, Cavalli, & Behling, 2018), little is known of litter decomposition and subsequent nutrient release to a succeeding crop in typical ICLS that include trees.…”

Residue decomposition from pastures and crops plays an important role in nutrient cycling in integrated crop-livestock systems (ICLS). The objective of this research was to quantify dry matter decomposition and nutrient release-nitrogen, phosphorus, and potassium (N, P, and K, respectively), the most commonly required nutrients in tropical and subtropical agriculture-from pasture and soybean (Glycine max) residues of stocking and crop seasons in two ICLS (with and without trees, CLT and CL, respectively) and two N fertilization levels (90 vs. 180 kg N ha −1 , N90 and N180, respectively, applied during the pasture phase). Litter bag incubations were set out in the December 2014 (soybean phase) and May 2015 (pasture phase), and retrieved after 7, 15, 30, 60, 90, and 120 d in each season. The total N, P, and K released from the pasture or soybean residues were related to the initial quantity of plant residues, which was reduced in the CLT systems, mostly for pasture residue (−60%), probably due to light reduction (−55%), rather than changes in litter quality and dynamics. Significant amounts of N (∼57 kg ha −1 ), P (∼11 kg ha −1 ), and K (∼58 kg ha −1 ) were cycled, particularly in CL and N180 treatments. The quantities of K released from pasture residues were enough to restore the quantity of K exported by soybean grains. Therefore, results reinforce the need to understand nutrient release patterns from residues to improve fertilization management.Abbreviations: CL, crop-livestock systems; CLT, crop-livestock systems with trees; DBH, diameter at breast height; DM, dry matter; Gha, animal gain per hectare; Ht, total height; ICLS, integrated crop-livestock systems; LW, live weight; N180, 180 kg N ha −1 ; N90, 90 kg N ha −1 .

Integrated crop-livestock systems (ICLSs) appear as a good alternative to increase nutrient use efficiency (NUE) in rice (Oryza sativa L.) through the improvement in nutrient cycling and soil chemical attributes in paddy fields. The objective of this study was to evaluate the impact of an ICLS on soil chemical attributes and on the fertilization requirement of N, P, and K by flooded rice in the Brazilian subtropical region. Nutritional status, yield, and NUE of flooded rice were evaluated by fertilization trials through rice response to different fertilization rates of N, P, and K. Soil chemical attributes were evaluated at the beginning of the experiment and 30 mo later.Different fertilization rates were applied in two systems: (a) a conventional system (CS), based on intensive tillage, rice monocropping and winter fallow, and (b) ICLS, characterized by no-tillage and winter cattle grazing in annual ryegrass (Lolium multiflorum Lam.) pasture. Rice shoot accumulation of N, P, and K was greater under CS than ICLS at all fertilization levels. On the other hand, higher rice yields were observed under ICLS at almost every fertilization level, suggesting higher NUE than CS. In addition, rice yield was increased by 40% by fertilization of P and K under CS, whereas no response was observed under ICLS. These benefits were possibly related to greater nutrient cycling and greater synchronism between rice's nutrient uptake and nutrient release of the soil. Our results indicate that the adoption of ICLS ensures greater NUE becoming a system less dependent on external inputs.Abbreviations: CEC, cation exchange capacity; CS, conventional system; ICLS, integrated crop-livestock system; NUE, nutrient use efficiency; SOM, soil organic matter.
