Working Document Series Open Access Improving Maize-Beans Yields Through Improved Soil Moisture Storage using Trapezoidal Bunds and Manure in Machakos County-Eastern Kenya B.O. Danga · B.E. Mochoge · G.S. Openda The tremendous increase in population in Kenya has created the need for faster rate of increase in food production. However, more than 80% of Kenya lies in the arid and semi arid lands (ASALs). To mitigate food shortages in such areas, the… RUF-31997 2012 CC BY 4.0 13 May 2014
Working Document Series Open Access Effects of NP Fertilisers and Manure Application on Maize-bean Yields, and Soil Nitrogen Mineralisation in Machakos County, Eastern Kenya C. Kibunja · B.E. Mochoge · N. Ogucha The inherent poor fertility of soils in Kenya constitute a major constrain to sustainable smallholders agriculture and more especially in arid and semi-arid parts of the country. The solution herein lies in the efficient use of nutrients a… RUF-31846 2012 CC BY 4.0 8 May 2014
