Extracellular soil enzymes play a key role in organic matter decomposition and nutrient cycling. However, it is not fully understood how these respond to different land use. Long-term research studies were used evaluate diversified management practices affect extracellular driving C cycling [phenol oxidases (PO), peroxidases (PP), α-glucosidase (AG), β-glucosidase (BG), cellobiohydrolase (CB), β-1,-4-Nacetylglucosaminidase (NAG)], N [leucine aminopeptidase (LAP)], P [phosphomonoesterase...
Incorporating shrub willow chips into soil may improve the chemical, physical and biological properties of soils with low organic matter but impact on microbial communities their dynamics is not known. We assessed changes in response to chip applied at increasing rates (0, 20, 40 60 Mg ha-1) a potato-barley cropping system. Bacterial fungal community diversity, relative abundance, potential functions were using amplicon sequencing 16S ITS rRNA genes six time points. High (40 had no effect...
Core Ideas We assessed long‐term manure rates and application times on soil nutrients enzymes at two sites. Increasing rate enhanced fertility but hydrolase showed a quadratic trend. Manure prior to period of heavy rainfall (spring fall) was associated with phosphorus losses. Peroxidase phenol oxidase activities declined increasing rates. Oxidative enzyme were good indices organic carbon storage. investigated how (soil [SOC], nitrogen [N], Mehlich‐3‐extractable [P‐M 3 ]) involved in their...
Potato ( Solanum tuberosum L.) crops are often cultivated in coarse-textured soils with low soil organic matter and high nitrate leaching risk. Incorporating shrub willow chips into could enhance properties, while temporally immobilizing N thus reducing leaching. We performed a laboratory incubation study field experiment to evaluate the effects of applied at increasing rates fall after potato harvest on C, P cycling, pH moisture, barley Hordeum vulgare yield following year. In comparison...
