Various environmental factors and anthropogenic practices can affect the Fe biogeochemical cycles in soils. Nitrogen carbon states are closely associated with dynamics. However, we still have a limited understanding of complex response processes to long–term nitrogen– organic–fertilization regimes. This study investigated fraction distribution, as well link between nitrogen/carbon, bulk soil ag...

Treated domestic sewage (TDS) can contribute to plant nutrition and improve crop production. However, there are no data for its use in coloured cotton under a deficit or excess irrigation combination with potassium fertilization rates (KRs), mainly semiarid tropical conditions. The research was conducted using randomized complete block design factorial scheme (5 × 5, regimes vs. rates), plus an...

Background: There is increasing evidence that the reliance on synthetic chemical pesticides and mineral fertilizers in agriculture has significant negative environmental and/or health impacts poses a risk for future food security. Systematic reviews/meta-analyses showed organic production systems, which omit use of agrochemicals, produce crops with lower yields, but superior nutritional composi...

BACKGROUND Efficient information systems support the provision of multi-disciplinary aged care and a variety of organisational purposes, including quality, funding, communication and continuity of care. Agreed minimum data sets enable accurate communication across multiple care settings. However, in aged care multiple and poorly integrated data collection frameworks are commonly used for client...

water and nutrient availability are two major constraints to forage maize production in arid and semi-arid areas; however, the effect of different n levels from organic and inorganic sources on nutrient (i.e., n and p) efficiency under drought stress conditions is not well known for maize faming. thus, a field study was conducted with the objective of determining the effect of n fertilization a...
