Spring barley yield and nitrogen recovery after application of peat manure and pig slurry [PDF]

open access: yes, 2006
The effectiveness of peat manure, manufactured of pig slurry and moderately humified Sphagnum peat (slurry:peat ca. 1:1.5 v/v), as nitrogen (N) source for spring barley was investigated in a four.year field experiment on a clay loam soil in south-western

Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)

open access: yesAdvanced Science, EarlyView.
Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

Double E─H Bond Activation of Ammonia and Water by Cyclic Gallaphosphene L(OCP)GaPGaL

open access: yesAngewandte Chemie, EarlyView.
Cyclic gallaphosphene 1 undergoes a twofold E─H bond activation with ammonia and water via a beneficial interplay between the polar “GaPGa” unit and the electrophilic nature of the C center in the bridging PCO unit, yielding six‐membered heterocycles 2 and 3, in which both nucleophilic phosphorus atoms are protonated.

Phosphorus Fertilizer Recommendations for Sugarcane Production on Florida Organic Soils

open access: yesEDIS, 2012
Much of the sugarcane grown in South Florida is on organic soils in the Everglades Agricultural Area, which is a phosphorus-limited system. Phosphorus loads in drainage water in the Everglades Agricultural Area are an environmental concern, so it is ...

ONION RESPONSE TO PHOSPHORUS FERTILIZER

open access: yesPakistan Journal of Science, 2022
Onion (Allium cepa L.) is among the most important food plants with high nutritional value, but insufficient application of phosphorous is one of the constraints to the yields. Research on onion responses to different doses of phosphorus will optimize fertilizer dose, making the practice more competitive with less environmental effects.

Long‐Term Active Rather than Passive Restoration Promotes Soil Organic Carbon Accumulation by Alleviating Microbial Nitrogen Limitation in an Extremely Degraded Alpine Grassland

open access: yesAdvanced Science, EarlyView.
Active restoration increases soil organic carbon stocks by reducing microbial nitrogen limitation. Nitrogen availability promotes particulate to mineral‐associated organic carbon conversion by reducing microbial carbon use efficiency. Passive restoration has no effect on soil organic carbon stocks.

Extractability of slurry and fertilizer phopshorus in soil after repeated freezing [PDF]

open access: yes, 2005
The potential effects of freezing on phosphorus (P) chemistry in Finnish soils are not well known. We studied the effects of multiple freeze-thaw cycles on soil P chemistry in a laboratory incubation experiment with one organic and one mineral surface ...
