The behaviour of nitrogen fertilizers in neutral and acid loess soils II. Distribution and balances of 15 N‐tagged nitrogen

Mochoge, B. O.; Beese, F. (Wiley-VCH Verlag, 1983)

A study, to investigate the remaining fertilizer-N in undisturbed soil columns from agricultural and forest soils after 60 days of percolation (see part I), was carried out. The columns were fertilized with two 15-N tagged ...

Simulation of nitrate movement in undisturbed soil columns

Mochoge, B. O. (Elsevier Masson, 1984)

In order to simulate the behaviour of nitrate movement in soils, two loessal soils were used which differed in their physical and chemical fertility. Undisturbed soil columns of 30 cm in length and 15 cm diameter were ...

Leaching of plant nutrients from an acid forest soil after nitrogen fertilizer application

Mochoge, B. O. (Springer Verlag, 1986)

In a laboratory experiment, the effect of nitrogen fertilizers on the leaching patterns and input-output budgets of plant nutrients in an acid soil (dystric cambisols) was studied. An amount of N corresponding to 80 kg/ha ...

Concentrations of isometamidium chloride (Samorin®) in sera of Zebu cattle which showed evidence of hepatotoxicity following frequent trypanocidal treatments

Eisler, M.C.; Stevenson, P.; Munga, L.K.; Smyth, J.B.A (Blackwell Publishing, 1997)

The concentrations of isometamidium circulating in poorly nourished Zebu cattle which showed morbidity, mortality, and biochemical and histopathological evidence of hepatotoxicity, following frequent treatments with ...

An epidemic of besnoitiosis in cattle in Kenya

Munga, L.K.; Njagi, O.N.; Ndarathi, C.M.; Nyaga, P.N. (AOSIS OpenJournals, 1998)

A total of 17 head of cattle presenting with typical "Elephant skin disease" were isolated from the rest of the herd within a beef ranch for further clinical observation. On physical examination, all the animals had ...

Rinderpest vaccination and the incidence and development of trypanosomosis in cattle.

Munga, L.K.; Stevenson, P.; Ndung'u, E.K.; Rossiter, P.B.; Dolan, R.B. (Springer Verlag, 1999)

An investigation was made into whether recent vaccination of cattle with tissue culture rinderpest virus would cause immunosuppression and lead to more frequent or more severe infection with trypanosomes in animals grazing ...

Alley cropping of maize with calliandra and leucaena in the subhumid highlands of Kenya Part 1. Soil-fertility changes and maize yield

Mugwe, J. N.; Mugendi, D.N.; Nair, P. K.; O’neill, M. K.; Woomer, P. L. (Kluwer Academic Publishers., 1999-06-01)

Although N-rich leaf biomass of multipurpose trees is known to be a good source of N to crops, integrating such trees into crop production systems is a major challenge in the development of viable agroforestry systems. ...

Short communication effect of lime, urea and triple super phosphate on nitrogen and phosphorus mineralisation in an acid soil during incubation

Mochoge, B. O.; Onwonga, Richard N.; Lelei, Joyce J. (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 ...
