NITROGEN FORMS IN THREE KENYAN SOILS ANDOSOLS, LUVISOLS AND FERRALSOLS
International Journal for Innovation Education and Research, 2016 The nitrogen cycle in soil is an integral part of the overall cycle of N in nature. The primary source of N is the atmosphere where the strongly bonded gas molecule N is predominately gas (78.08%). Total N content in soils ranges from 0.02% in the subsoil and more than 2.5% in peats; ploughed layers of most cultivated soils contain between 0.06 and 0.5%

Uso de barreras cortavientos en un luvisol cultivado de olivos
, 2020 RESUMEN: Uso de redes cortavientos para disminuir la erosión y el transporte de sedimentos en un área concreta semiárida. Un hilo de 13x30 cm-2 y con una red de malla del 39 % frente al viento aumentaron la reducción promedio de erosión hasta un 72% a una altura de 0.4 m en olivares labrados recientemente.

Soil biological quality in short- and long-term field trials with conventional and organic fertility input types [PDF]
, 2007 Soils of the DOK trial and three other field trials with manure input were analysed for effects on soil biology. While long-term effects indicate a new steady state at the DOK trial site, differences at the other field trials suggest that fresh manure at

Topsoil Stripping in Potentially Arable Forested Luvisols: A Literature Review
Education and Research Archive, 1990 The objective of this literature review was to evaluate the available information on the effects of stripping versus not stripping topsoil during pipeline construction in potentially arable Luvisolic soils in forested areas. A profile description representative of an undisturbed Luvisol under native forest vegetation was studied to identify potential ...
