Abstract

This study aimed to verify the applicability of a mass balance method for estimating nitrogen (N) and phosphorus (P) content in the solid organic fertiliser produced from cattle manure in North-West Russia. The study compared the relevant established norms in Russia, the data calculated by the mass balance method, and the average experimental data on N and P content in cattle manure (ex-housing) and the organic fertilizer ready to use from the selected cattle-breeding complex with 1250 heads and a manure output of 70 t day-1. Three animal categories were considered. The difference between the calculated and experimental data was 10% maximum but the experimental data and the established norms differed by above 15%. This proves the demand to revise the norms in the Russian regulatory documents to improve the accuracy of fertiliser application rates and the estimation of agricultural land required. Even an increase of 10% in the nutrient content of the organic fertiliser results in an increase in the required agricultural land from 451 to 526 ha for spreading the organic fertiliser from the 1250 heads of cattle at the selected farm.

修订总氮和磷含量的牛粪为基础的有机肥料在俄罗斯西北部

本研究旨在验证质量平衡法在估算俄罗斯西北部牛粪生产的固体有机肥中氮(N)和磷(P)含量的适用性。本研究选取1250头、粪便产量70 t day-1的牛场，比较了俄罗斯相关的既定规范、质量平衡法计算的数据和牛粪(除舍粪)中氮、磷含量及准备使用有机肥的平均实验数据。考虑了三种动物类别。计算值与实验值的差异最大为10%，而实验值与既定规范的差异在15%以上。这证明需要修改俄罗斯监管文件中的规范，以提高肥料施用量和所需农业用地估算的准确性。即使有机肥料的养分含量增加10%，也会导致所需的农业用地从451公顷增加到526公顷，用于在选定的农场中从1250头牛中施用有机肥料。

期刊介绍： Agricultural and Food Science (AFSci) publishes original research reports on agriculture and food research related to primary production and which have a northern dimension. The fields within the scope of the journal include agricultural economics, agricultural engineering, animal science, environmental science, horticulture, plant and soil science and primary production-related food science. Papers covering both basic and applied research are welcome. AFSci is published by the Scientific Agricultural Society of Finland. AFSci, former The Journal of the Scientific Agricultural Society of Finland, has been published regularly since 1928. Alongside the printed version, online publishing began in 2000. Since the year 2010 Agricultural and Food Science has only been available online as an Open Access journal, provided to the user free of charge. Full texts are available online from 1945 on.
