UV-B radiation effects on nutrient concentrations in above-ground organs of maize were investigated at silking and maturity at different levels of applied nitrogen under field conditions. The experiment simulated a 20% stratospheric ozone depletion over Portugal. At silking, UV-B increased N, K, Ca, and Zn concentrations, whereas at maturity Ca, Mg, Zn, and Cu increased and N, P and Mn decrease...

Abstract Aims Fertiliser is often used to kick-start ecological restoration despite growing evidence of the potentially negative impacts on plant diversity. Jarrah ( Eucalyptus marginata ) forest species nutrient (especially phosphorus) impoverished soils in southwestern Australia have a suite adaptations for phosphorus (P) acquisition, including formation cluster roots, and associations with m...

Soil macrofauna are a critical component for ecosystem function and strongly affect production sustainability. The effect of fertiliser management practices, in different cropping systems, on soil communities remains poorly understood semi-arid to arid regions. objective this study was investigate the tillage practices i.e., no-till (NT), rotational (RT) conventional (CT) nitrogen application r...

Although the black soldier fly frass fertiliser (BSFFF) is globally recognised as a promising and potential high-quality organic fertiliser, there inadequate information on its impact growth performance nutritional status of maize. Furthermore, no exist their combination with mineral (NPK) well economic maize production. This study evaluated comparative BSFFF, NPK commercial (Evergrow ® ) growt...

Optimised Ammonia Sanitisation of Sewage Sludge Franziska Häfner The usage of sewage sludge as an organic fertiliser offers a way to recycle nutrients and organic matter for a sustainable agriculture. Sewage sludge is rich in plant nutrient like nitrogen, phosphorus, potassium and micronutrients. Concerning the depletion of phosphorus resources, the reuse of sewage ...
