Abstract: 

Soil is a fundamental resource for man’s life on earth, most of the goods he needs coming directly or indirectly from the soil. This is not done without compensation in favour of the soil, which loses its productive capacity over time. Compensation is made through the provision of both mineral and organic fertilizers to the soil. A trial was conducted in Ngandajika where it was applied to the soil, two organic fertilizers, Bat-guano and Tithonia diversifolia, a mineral fertilizer, DAP for growing corn. At the end of this test, the following results were recorded: the pH was increased from 5.20 to 5.80 with the application of Tithonia diversifoia manure. The carbon content increased from 2.3 to 2.93 Kg/Ha, the nitrogen content increased from 5.5 to 23.99 Kg/Ha with Tithonia diversifolia. As regards phosphorus, its content increased from 12.24 to 46.04 kg with NPK, potassium from 4.9 to 21.83 kg/ha with Tithonia diversifolia and calcium from 23.7 to 56.73 kg/ha with Bat-guano. Both organic and mineral fertilizers increase soil fertility.
