In Sub-Saharan Africa (SSA), acidic soil covers 29% of the total area. About 13% of the Kenyan total land area has acidic soils, widely distributed in croplands of the central and western Kenyan regions. The high soil acidity, coupled with soil nutrient depletion, negatively affects crop productivity in the region. We conducted an on-farm experiment to determine the effect of lime, manure, and phosphatic fertilizer application, either solely or combined, on soil chemical properties, maize yield, and profitability in acidic soils of Tharaka Nithi County, Kenya. The treatments were different rates of manure, lime, and P fertilizer. The experiment was designed as a randomized complete block design replicated ten times in farmer’s fields. Soil sampling was done at a depth of 0-20 cm prior to the start of the experiment, after crop harvest of SR2016 and LR2017 seasons. The samples were analyzed in the laboratory following standard methods. Results showed that lime significantly increased soil pH by 10.6% during the SR2016 and by 17.7% during the LR2017. Similarly, treatments with lime reduced exchangeable acidity and increased soil available P. Treatments with inorganic fertilizers had significantly higher maize grain yield in comparison with treatments with the sole application of lime, manure, and lime + manure. Lime + fertilizer + manure treatment gave the highest average maize grain yield (5.1 t ha−1), while control gave the lowest (1.5 t ha−1) during the LR2017 season. Economic returns were low due to the prevailing low rainfall experienced during the study period during the SR2016 season. Lime combined with inorganic fertilizer treatment recorded the highest returns (128.75 USD ha-1) followed by sole inorganic fertilizer (105.94 USD ha-1) during the LR2017 season. The study recommends a combination of both lime and inorganic fertilizer for enhanced maize production and profitability in Tharaka-Nithi County, Kenya.

Background: Low soil productivity in Nigeria and Africa sub sahara is considered as one of the major causes of food insecurity and under nutrition. This area is considered among the most regions affected by acidity on soil nutrients optimization. Despite of its severity, there is limited knowledge about limiting effect of pH on nutrients availability and maize yield in the state. Evolving a technology that does not depend on traditional system of amendment for pH assessment for increased soil productivity must first of all go through a good knowledge of the nature and distribution of soil studied. The present study aimed to evaluate three pH (4, 7 and 9) values on soil chemical properties in the state and assess maize performance under these conditions in order to control and manage pH related problems. Methods: In the field-laboratory investigation during 2018-2019 at different localities of Ebonyi State were surveyed. Three sampling localities were selected based on geographical situation, climate and local condition. In the laboratory, the soil samples of natural stock collected were processed for mean pH values and confirmed with pH meter using standard laboratory method. Maize was used as test crop to assess effect of pH on its performance. Result: Our investigations in Ebonyi State have allowed us to inventory three pH values. Among the inventoried pH values, some are regarded adverse for soil productivity. The implication of soil pH on nutrients availability and maize performance was discussed. The current work will be a complementary contribution of detailed study of effect of pH on soil productivity.

ABSTRACT Organic materials subjected to a process of anaerobic digestion in a digester produce biofertilizer that can be used in agriculture as nutrient source. The objective of this study was to evaluate the effect of pig slurry biofertilizer on soil chemical properties and on corn yield and nutrient concentrations in leaves and kernels. The experiment was conducted in the field from November 2012 to April 2013, and was arranged in a randomized block design with seven treatments and four replicates. The treatments consisted of doses of pig slurry biofertilizer (0; 40; 80; 120; 160; 200 and 240 m3 ha-1), applied to the soil surface in a single application, at stage V2 of corn plants. Thirty-three days after biofertilization, soil samples were collected in each plot. Corn was harvested 129 days after sowing. Doses up to 240 m3 ha-1 of pig slurry biofertilizer applied to soil with good fertility did not influence soil chemical properties and corn yield. The use of pig slurry biofertilizer had no detectable effect on nutrient concentrations in corn leaves and kernels.

Soil organic matter, nitrogen (N), phosphorus (P) and potassium (K) nutrition of rice-maize cropping systems are important for sustaining crop productivity and food security. An experiment was conducted to determine the effects of tillage practices and residue retention on soil chemical properties in rice-maize cropping system. Conventional tillage, single pass wet tillage in rice (rotated with zero tillage in maize), bed planting (unpuddled rice transplanting) and strip tillage (unpuddled rice transplanting) in vertical plots and residue retention (0, 50 and 100%) in horizontal plot were tested for three consecutive years (2009-12). Rice was grown as transplanted irrigated crop and maize as upland crop. After third crop, strip tillage increased soil organic matter compared to bed and zero tillage at 0–7.5 cm soil depth. After three years, retention of crop residues, irrespective of tillage treatments, increased soil organic matter (SOM) at 7.5–15.0 cm soil depth. Tillage practices (puddled or unpudled) showed no significant changes in SOM. Neither tillage nor residue management had any significant effect on soil pH, total nitrogen, available phosphorus and exchangeable potassium.DOI: http://dx.doi.org/10.3329/agric.v13i2.26589The Agriculturists 2015; 13(2) 62-73
