Transfer and Development of Pasteuria Penetrans.
(The Society of Nematologists, 2007-03)
Pasteuria penetrans isolate P-20 has been attributed as the cause of soil suppressiveness to peanut root-knot nematode in Florida. In this study, P. penetrans was transferred from a suppressive site to a new site and ...
Interactive effects of lime, manure, N and P fertilizers on maize (Zea mays L.) yield and N and P uptake in an acid mollic Andosol of Molo Kenya
(Penerbit UTHM, 2006)
Maize production in Molo division, situated in the central Rift Valley is constrained by acid soil infertility and high P fixation. To realize maximum crop production, the acid infertile soil may be corrected through liming, ...
Short communication effect of lime, urea and triple super phosphate on nitrogen and phosphorus mineralisation in an acid soil during incubation
(Bioline International,, 2000)
A significant portion of soil N and P occurs in organic forms that are not available for crop uptake unless mineralised ( Stevenson, 1986; Tisdale et al., 1990). Slowed nitrification rates (Weber and Gainey, 1962) and P ...
The role of agroforestry trees in intercepting leached nitrogen in the agricultural systems of the central highlands of Kenya.
(East African Agricultural and Forestry Journal, 2003)
Application of N-rich tree biomass to crop fields in agroforestry associations can cause a build-up of mineral-N in the top soil in excess of crop demand during early stages of crop growth. It is therefore important ...
The Potential of Morning and Afternoon Supplementation of Scavenging Chickens on Diets with Varying Energy and Protein Levels.
(Centro para la Investigación en Sistemas Sostenibles de Producción Agropecuaria, 2009)
The effects of supplementing different diets with varying levels of energy and protein either in the morning or afternoon were assessed. 384 scavenging indigenous chickens aged 14 weeks were allocated to four treatment diets: ...
