ABSTRACT Background Placement and acidification pretreatments are strategies to enhance the phosphorus (P) fertilizer value of biowastes. However, their impact on commercial yield horticultural crops effects contents undesirable elements in edible product not well known. Aims The main objective this study was assess how placement biowastes affect nutritional quality vegetables. Methods To investigate this, we selected two byproducts from agroindustries, meat bone meal (MBM) digestate solid...
Abstract State‐of‐the‐art predictive models of soil organic carbon (SOC) dynamics associated with land use changes are unable to reflect the diversity tropical types as knowledge contrasting site‐specific factors in mediating response SOC pool is sparse. This paper examines influence type and management on following conversion forests annual cropping Ghana. Soil from primary areas short (2–7 years) long (20 histories maize cultivation was sampled a Vertisol dominated by smectite Ultisol...
A number of root and hair traits have been proposed as important for nutrient acquisition. However, there is still a need knowledge on which are most in determining macro- micronutrient uptake at low soil fertility. This study investigated the variations growth vigour length density among spring wheat genotypes their relationship to concentrations during early growth. Six were grown with availability. The well concentration content micronutrients identified. significant genetic variability...
Abstract Cover crops increase carbon (C) inputs to agricultural soils, and thus have the potential mitigate climate change through enhanced soil organic (SOC) storage. However, few studies explored fate of belowground C associated with varying root traits into distinct SOC pools mineral‐associated (MAOC) particulate (POC). Therefore, a packed 0.5 m column trial was established 0.25 topsoil subsoil four cover species (winter rye, oilseed radish, chicory, hairy vetch) known differ in C:N ratio...
ABSTRACT The pH‐dependent release of cadmium, copper, and lead from soil materials was studied by use a stirred flow cell to quantify their rates, evaluate the method as test for bonding strength potential mobility heavy metals in soils. Soil sludge‐amended nonamended A horizons Thai coarse‐textured Kandiustult Danish loamy Hapludalf were characterized tested. For each sample, experiments with steady state pH values range 2.9 7.1 duration 7 d performed. effluent continuously collected...
We investigated immediate and long-term effects on bacterial populations of soil amended with cattle manure, sewage sludge or municipal solid waste compost in an ongoing agricultural field trial. Soils were sampled weeks 0, 3, 9 29 after fertilizer application. Pseudomonas isolates enumerated, the impact community structure was using 16S rRNA amplicon pyrosequencing. Bacterial at phylum level remained mostly unaffected. Actinobacteria, Proteobacteria Chloroflexi most prevalent phyla...
Managing phosphorus (P) losses in soil leachate folllowing land application of manure is key to curbing eutrophication many regions. We compared P leaching from columns variably textured, intact soils (20 cm diam., 20 high) subjected surface or injection dairy cattle (Bos taurus L.) slurry. Surface slurry increased relative baseline losses, but declined with increasing active flow volume. After elution one pore volume, averaged 0.54 kg ha(-1) the loam, 0.38 sandy and 0.22 loamy sand...
Abstract The large scale conversion of extensive swidden agriculture to intensive market oriented production maize in upland areas South East Asia is a cause environmental concern. This study investigates how cultivation affects soil quality an area Northern Thailand by comparing commonly used indicators soils from fields at various intensities. Relations between these and concentration permanganate oxidizable carbon (Pox‐C) – low cost proxy for are also examined. extent, type drivers land...
Abstract Limited nutrient availability is one of the major challenges in organic farming. Little known about budgets farms, underlying factors or effects on soil fertility. We therefore assessed farm gate for nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg) and sulfur (S) 20 farms Germany analyzed their nutri-ent status. In average, showed a surplus N (19 kg ha−1), K (5 S (12 Mg (7 deficit P (−3 ha−1). There was, however, high variability between (e.g. standard deviation up to ±...
