Phosphorus (P) constraint can be alleviated by increasing C inputs, which help to improve crop production and P fertilizer use efficiency. However, the effects of different manures on soil microbial biomass (MBP) fractions as well in calcareous soils remain poorly understood. Soil MBP pool involves mineralization immobilization processes, potentially changing availability. Therefore, (MBP, MBC)...

Abstract The rising generation of organic waste (OW) can be a concern, representing at the same time valuable opportunity for phosphorous (P) recycling; however, yet little is known about plant-available P release from this source. In work, two anaerobic digestates, agro- (AW D ) and bio-waste (BW ), their respective composts C BW were selected to assess P-release via sequential chemical extrac...

Abstract Background The soil P leaching change point (CP) has been widely used to evaluate risk. However, an automation calculation method for CP value, and effective risk grading performed classifying evaluation have not developed. Results This study optimized the process value with two different fitting models. Subsequently, based on Python programming language, a computation tool named Soil ...

It is well established that shallow tillage (ST) and no-tillage (NT) of cultivated soils can have higher risk dissolved phosphorus (P) loss during runoff than conventional (CT). However, quantitative descriptors how differences in practices influence soil P sorption properties these turn remain lacking. Moreover, the on forms P, particularly molybdate unreactive (MUDP), has rarely been investig...

GPS-equipped mobile devices such as smart phones and in-car navigation units are collecting enormous amounts of spatial and temporal information that traces a moving object’s path. The exponential increase in the amount of such trajectory data has caused three major problems. First, transmission of large amounts of data is expensive and time-consuming. Second, queries on large amounts of trajec...

Abstract Continuous manure application based on crop nitrogen (N) requirements could substantially increase field nutrient losses from croplands. Although phosphorus-based (P) is an alternative, crops may suffer potential microbial P immobilization and fixation of in soil. A three-year study (2012–2014) was carried out Manitoba, Canada, to evaluate the agronomic environmental benefits tradeoffs...

Abstract Belowground and aboveground interactions are important in increasing yield nutrient-use efficiency intercropping. However, how the P-use respond to shoot-root intercropping remains unknown. Maize mono- was grown under field conditions (regosol soil, initial Olsen-P 12.6?mg?kg?1) with P supply of 0 35?kg ha yr-1 (P0 P35, respectively) for 3 years. Compared monocropping, significantly in...

Soil microorganisms directly participate in phosphorus (P) cycle, which turn affects crop yield and quality. However, how biological chemical parameters respond to mineral P fertilizer application rates rhizosphere soil remains unclear. Here, a pot experiment was conducted investigate the effects of different (0, 60, 120, 300 kg P2O5 ha−1) on properties bacterial community maize Mollisol. With ...

Zinc (Zn) nutrition is of key relevance in India, as a large fraction of the population suffers from Zn malnutrition and many soils contain little plant available Zn. In this study we compared organic and conventional wheat cropping systems with respect to DTPA (diethylene triamine pentaacetic acid)-extractable Zn as a proxy for plant available Zn, yield, and grain Zn concentration. We analyzed...
