“…In this study, nutrient demand of crop and nutrient supply of manure were considered to calculate the R value as previous studies by Zheng et al (2019) and Zhu et al (2020), and the classification standard was the same as that used by Wang et al (2017). The R results showed that the risk of phosphorus was higher than that of nitrogen, which was mainly due to the larger contribution of nitrogen to the plant nutrient cycle than phosphorus (Lassaletta et al 2014;Li and Liu (2020)).…”

“…The index of livestock manure N or P load on farmland has been proposed to estimate the carrying capacity of local livestock farms (Jia et al 2015 ; Yang et al 2016 ; Yan et al 2017 ; Zhang et al 2019 ) and identified the environmentally critical regions of livestock farming in mainland China (Zheng et al 2019 ). Li and Liu ( 2020 ) used the soil’s own nutrient-supplying capacity as an empirical method to accurately determine the carrying capacity and environmental risks of the livestock and poultry breeding in Jiangsu Province. Wen et al ( 2020 ) compared the farmland area required for the reasonable consumption and utilization of the livestock manure nitrogen nutrient with the actual farmland area to assess the risk in Wuhan.…”

Decoupling livestock and cropland production at regional scale have poor resource-use efficiency and detrimental effects on environment in China. It is therefore necessary to identify the decoupled livestock and cropland production system and make recommendations to recouple livestock and cropland. This study used the indexes of land carrying capacity (LCC), animal manure absorption capacity (AMAC), and risk warning value (R) to evaluate the coupling between cropland and livestock at the local scale in the Huang-Huai-Hai region. The decoupling of cropland and livestock in the case of Beijing (SY_BJ) was found assessed with lower theoretical value of LCC and higher theoretical value of AMAC compared with local actual situation, categorized as grade IV with a high R value (above 1). Contrary results were found that the livestock and cropland production systems were coupled at the local scale in the cases located in Hebei and Shandong Provinces, categorized as grade I or II. Two measures were used to optimize the decoupled case by adjusting the ratio of manure to fertilization or reducing breeding quantity. The decoupled case of SY_BJ could be optimized by adjusting the ratio of manure to fertilization (95.34% based on nitrogen and 81.97% based on phosphorus, respectively). The breeding quantity in this case should be reduced by at least 46% to recouple the livestock and cropland at the local level to manage nutrient surpluses from livestock and poultry breeding.

“…Feces and urine released from livestock and poultry breeding can be used as organic fertilizers for agricultural production (Li and Liu, 2020), but superabundant waste generated by the livestock and poultry breeding caused a serious pollution for farmland because of the limited land capacity. According to animal manure production (Equation ( 2)) and farmland area, the animal manure load on farmland was able to be obtained as shown in Equation (4).…”

Effect and Risk Assessment of Animal Manure Pollution on Huaihe River Basin, China

Currently the deteriorated water quality for Huaihe River Basin (HRB) in China was still serious because of the negative influence multiple pollution sources including animal manure. However, little attention was paid to the potential risk of animal manure for farmland and water quality of HRB. This study was quantified and forecasted animal manure risk and its spatiotemporal variations in HRB from 2008 to 2018, through pollution discharge coefficient method and pollution load calculation, combined with kriging interpolation method of ArcGIS technology, based on statistics principle. All the data were originated from livestock and poultry breeding in HRB from 2008 to 2018. The future risk of farmland and water environment in HRB was further forecasted. The results indicated that the livestock and poultry manure has become a key pollution source causing a negative influence on farmland and water quality owing to a large amount of animal manure production without efficient recycle utilization. The chemical oxygen demand (COD) and total nitrogen (TN) discharge of animal manure in HRB almost accounted for 17.00% and 39.00% of the whole COD and TN discharge in China. The diffusion concentration of TN and TP in those regions of Shangqiu,

“…The combination of planting and breeding and the cycle of farming and grazing are considered to be the most effective solutions at present [22]. Therefore, based on the idea of planting and breeding balance, scientifically measuring the nutrient demand of regional crop growth and the nutrient availability of livestock manure has become the key to adjusting regional planting and raising structure, reducing the application of chemical fertilizer, reducing environmental pollution, and achieving high-quality agricultural development [23]. In this context, research on the regional livestock carrying capacity of farmland is becoming increasingly abundant [24].…”

“…The existing research generally studies the livestock carrying capacity of farmland from the perspective of meeting the nutrient requirements of crops, through constructing the farmland consumption model of livestock breed waste based on the soil nitrogen and phosphorus nutrient-balance method [23,[26][27][28][29]. If the regional crops can absorb the livestock breeding waste in an equal proportion, the balance between planting and breeding in the region can be considered to be achieved [29].…”

In this paper, we selected the northeast region as a study area from the perspective of soil nutrient demand, calculated the livestock carrying capacity of farmland under three scenarios where nitrogen nutrient accounts for 35% (low level), 45% (medium level), and 55% (high level) of fertilization, and carried out a risk analysis. The results show that the scale of husbandry breeding is expanding and the scale of the planting industry has remained basically unchanged. Under the three scenarios, there were 23 regions where the livestock manure exceeded the maximum value that could be absorbed by farmland in 2008 and 28 regions in 2019. These regions in the potential area are mostly located in Heilongjiang province and the regions in the restricted area are mostly located in Liaoning Province. On the whole, the northeast region is generally faced with the problem of livestock overloading, and the insufficient utilization and treatment capacity of livestock manure poses a huge threat to regional ecological security. Based on this, adjusting the structure of regional planting and breeding, promoting the development of the livestock manure processing industry, enhancing the production capacity of organic fertilizer, and constructing an integrated pattern of regional planting and breeding are effective ways to realize the sustainable utilization of farmland in northeast China.
