Availability of Nutrients Soil pH influences the solubility of nutrients. It also affects the activity of micro-organisms responsible for breaking down organic matter and most chemical trans-formations in the soil. Soil pH thus affects the availability of several plant nutrients. A pH range of 6 to 7 is generally most favorable for plant growth because most plant nutrients are readily soil pH 6.0-7.5 is acceptable for most plants as most nutrients become available in this pH range. Soil pH is important because it affects the availability of nutrients to plants.

Specifically, if water and nutrient availability coincide (primarily available to the same roots), we would expect no evidence for sectoriality.

In the same line, application of lime increased soil pH, enhanced nutrient availability (Ca, Mg and P) and recorded mammoth yield increase of maize compared to treatments without lime in acid soils of Ghana (Buri et al., 2005). Many nutrients are more available in slightly acid soils: P is most available at a neutral pH (about 6.5); Mb is available at high pH and can be toxic to plants. The pH is also important in N transformations, such as mineralization, nitrification, and N fixation, as the bacteria involved are pH-sensitive.

The effect of N-Viro application on the soil properties, soil nutrient availability, plant nutrient uptake, and the fruit yield of the lowbush blueberry under irrigated and nonirrigated Nova Scotian conditions is unknown. This study was conducted to fill this knowledge gap in order to develop economically viable and environmentally accepted nutrient management strategies for the use of N-Viro nutrient availability, humification, and soil porosity [12]. On the other hand, soil microbes have been recognized to influence crop productivity by controlling N dynamics and its synchrony with crop demand [5], hence their presence is important in soil productivity studies especially in SSA soils where high nutrient deficiencies have been reported [13]. This study is one of the few reports
