Ameliorating acid infertile rice soil with organic residue from nitrogen fixing trees por Baggie, I., Zapata, F., Sanginga, N., Danso, S.

“…Ground and dried residues were mixed with soil and labelled with N15 ammonium sulfate (9.855% atom excess) at a rate of 10 mg N kg-1 soil. The 32P isotopic exchange method was used to determine the effect of organic residue incorporation on the bioavailable soil P status at five levels of P application. …”

Evaluación del valor nutritivo de subproductos del camarón en la alimentación de pollos por Jarquin, R., Braham, J.E., Gonzalez, J.M, BRESSANI, R.

“…Besides the lysine deficiency, excess of calcium in these by-products could have also been the responsible factor for their poor nutritive quality, since the addition of phosphorus improved the growth rate of the chickens.…”

Carbon offset management : worth considering when investing for reforestation CDM por Eriksson, Arvid

“…To get through an A/R CDM process the company is exposed to the risk of failing the process or that the overall costs will exceed the benefits of the project. This would delete the incentives to invest in GHG removals compared to purchasing emission allowances on the carbon market. …”

Resource distribution in disturbed landscapes – the effect of clearcutting on berry abundance and their use by brown bears por Domevscik, Matej

“…To survive winter hibernation, brown bears (Ursus arctos) need to store excess energy during late summer and autumn. Scandinavian brown bears usually have an abundance of berries to feed on, but their distribution varies depending on forest structure and age. …”

Embedding food system education into Swedish public schools – teachers’ perspectives por Weiss, Hanna

Magasin för lagring av vatten och växtnäring por Sandin, Maria

“…Nutrients are lost from crop producing farms as harvest products are sold, while farms with animal production often have manure in excess of their needs. In addition to this the retention of water and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number and size in the agricultural landscape. …”

Nitrogen release and synchrony in organic and conventional farming systems of the central highlands of Kenya por Musyoka, M.W., Adamtey, N., Bünemann, Else K., Muriuki, A.W., Karanja, E.N., Mucheru-Muna, M., Fiaboe, K.K.M., Cadisch, Georg

“…However, under maize strong temporal N immobilization from inputs occurred, particularly at Thika, related to the poor quality of manure and compost (lignin:N ratio > 13). In all systems, excess-asynchrony of available N was pronounced during vegetative stages and at harvest, while insufficient-asynchrony occurred at reproductive stages. …”

A double ITCZ phenomenology of wind errors in the equatorial Atlantic in seasonal forecasts with ECMWF models por Shonk, Jonathan KP, Demissie, Teferi Dejene, Toniazzo, Thomas

“…The transition is a seasonal feature of the model climatology (independent of initialisation date) and is associated with a seasonal increase in rainfall where a second branch of the ITCZ is produced south of the Equator. Excess off-equatorial convergence redirects the trade winds away from the Equator. …”

Bank stability and toe erosion model as a decision tool for gully bank stabilization in sub humid Ethiopian highlands por Zegeye, Assefa D., Langendoen, E.J., Steenhuis, T. S., Mekuria, Wolde, Tilahun, Seifu A.

“…The simulated results showed that a 5 m deep gully was stable under fully saturated conditions when the bank toe is protected, its upper surface is vegetated, and its bank angles do not exceed 45°. If the depth of the gully is less than 5 m or if its water table is deeper than 0.5 m, only regrading the gully bank to an angle of 45° can stabilize the gully. …”
