There was analyzed the effect of selected essential oils (orange, lemon, vanilla, linden blossom, thyme, geranium and tea oils) on the development and fertility of the most dangerous cereal grain stor...
Soil Mineral N Dynamics in a Maize Crop Following Different Soil Fertility Amendments in Different Soil Fertility Status in Sub-humid and Semi-arid Regions in Central Kenya
N uptake Organic inputs Nitrate ammonium
2010/11/15
Nitrogen is the major limiting nutrient in crop production and it is also one of the nutrients that is easily lost from the plant-soil system in various ways. Due to this, N supply, N management and N...
Factors responsible for differences in uptake of integrated soil fertility management practices amongst smallholders in western Kenya
