“…In a survey by [8], the authors reported on large quantities of good quality indigenous organic materials with widespread distribution in Ghana. The authors observed that using 3 t ha -1 of organic materials from crop residues with supplementary NPK fertilizer gave synergistic effect on soil fertility, soil chemical properties and soil buffer capacity, in lowland rice fields.…”

Integrated soil fertility management technology fits into the status of resource poor farmers in the Guinea savannah zone of Ghana. A field experiment was conducted at Nyankpala during the 2014 cropping season, to investigate the effects of Biochar, Rice husk and Rice straw and subsequently the residual impact on yield components and grain yield of maize. The study was a 3×3×3 factorial experiment consisting of three organic materials at three levels (2.5, 5 and 7.5 t ha-1 on dry matter basis) and three NPK rates (0-0-0, 45-30-30 and 90-60-60 kg ha-1) laid out in a Randomized Complete Block Design with four replications. The highest grain yield was obtained with 7.5 t ha-1 biochar (4825 kg ha-1) plus at 90-60-60 kg NPK t ha-1 , but 7.5 t ha-1 a biochar plus 45-30-30 kg NPK t ha-1 gave similar yield making the dose more acceptable. Longest cob was obtained with 5 to 7.5 t ha-1 of biochar (22.60 cm), or rice husk (20.69 cm), or rice straw (21.45 cm) plus at least 45-30-30 kg NPK ha-1.
